General Conditions 00 72 00-18 Corpus Christi Standards Rev 6/2021 2. No provision of referenced standard specifications, manuals, reference standards, codes, or instructions of a Supplier changes the duties or responsibilities of OPT or Contractor from those described in the Contract Documents or assigns a duty to or gives authority to the OPT to supervise or direct the performance of the Work or undertake responsibilities inconsistent with the Contract Documents. 3.

Each Change Order must be specific and final as to prices and extensions of time, with no reservations or other provisions allowing for future additional money or time as a result of the particular changes identified and fully compensated in the Change Order. The execution of a Change Order by Contractor constitutes conclusive evidence of Contractor's agreement to the ordered changes in the Work. This Contract, as amended, forever releases any claim against Owner for additional time or compensation for matters relating to or arising out of or resulting from the Work included within or affected by the executed Change Order. This release applies to claims related to the cumulative impact of all Change Orders and to any claim related to the effect of a change on unchanged Work. C. All Change Orders require approval by either the City Council or Owner by administrative action. The approval process requires a minimum of 45 days after submission in final form with all supporting data. Receipt of Contractor's submission by Owner constitutes neither acceptance nor approval of a Change Order, nor a warranty that the Change Order will be authorized by City Council or administrative action. The time required for the approval process may not be considered a delay and no extensions to the Contract Times or increase in the Contract Price will be considered or granted as a result of the process. Contractor may proceed with Work if a Work Change Directive is issued. D. If the Contractor refuses to execute a Change Order that is required to be executed under the terms of this Paragraph 11.07, the Change Order is deemed to be in full force as if executed by Contractor.

If this contract is covered by the EO,the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year. Employees must be permitted to use paid sick leave for their own illness, injury or other health-related needs, including preventive care;to assist a family member(or person who is like family to the employee)who is ill, injured,or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member(or person who is like family to the employee)who is a victim of,domestic violence, sexual assault, or stalking. Additional information on contractor requirements and worker protections under the EO is available at https://www.dol.gov/agencies/whd/government-contracts. Note: Executive Order 13658 generally applies to contracts Supplementary Conditions 00 73 00-6 CCIA Taxiway Echo Rehabilitation Rev 3/2023 Project No: 26122 subject to the Davis-Bacon Act that were awarded on or between January 1,2015 and January 29,2022, and that have not been renewed or extended on or after January 30, 2022. Executive Order 13658 does not apply to contracts subject only to the Davis-Bacon Related Acts regardless of when they were awarded. If a contract is subject to Executive Order 13658,the contractor must pay all covered workers at least$13.30 per hour(or the applicable wage rate listed on this wage determination, if it is higher)for all hours spent performing on the contract in 2025. The applicable Executive Order minimum wage rate will be adjusted annually. Additional information on contractor requirements and worker protections under Executive Order 13658 is available at www.dol.gov/whd/govcontracts. Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (iii)). ---------------------------------------------------------------- The body of each wage determination lists the classifications and wage rates that have been found to be prevailing for the type(s) of construction and geographic area covered by the wage determination.The classifications are listed in alphabetical order under rate identifiers indicating whether the particular rate is a union rate(current union negotiated rate), a survey rate, a weighted union average rate, a state adopted rate, or a supplemental classification rate. Union Rate Identifiers Supplementary Conditions 00 73 00-7 CCIA Taxiway Echo Rehabilitation Rev 3/2023 Project No: 26122 A four-letter identifier beginning with characters other than ""SU"", ""UAVG"", ?SA?, or?SC?denotes that a union rate was prevailing for that classification in the survey. Example: PLUM0198-005 07/01/2024. PLUM is an identifier of the union whose collectively bargained rate prevailed in the survey for this classification,which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198.The next number,005 in the example, is an internal number used in processing the wage determination.The date,07/01/2024 in the example, is the effective date of the most current negotiated rate. Union prevailing wage rates are updated to reflect all changes over time that are reported to WHD in the rates in the collective bargaining agreement (CBA)governing the classification. Union Average Rate Identifiers The UAVG identifier indicates that no single rate prevailed for those classifications, but that 100%of the data reported for the classifications reflected union rates. EXAMPLE: UAVG-OH-0010 01/01/2024. UAVG indicates that the rate is a weighted union average rate. OH indicates the State of Ohio. The next number,0010 in the example, is an internal number used in producing the wage determination.The date,01/01/2024 in the example, indicates the date the wage determination was updated to reflect the most current union average rate. A UAVG rate will be updated once a year, usually in January,to reflect a weighted average of the current rates in the Supplementary Conditions 00 73 00-8 CCIA Taxiway Echo Rehabilitation Rev 3/2023 Project No: 26122 collective bargaining agreements on which the rate is based. Survey Rate Identifiers The ""SU"" identifier indicates that either a single non-union rate prevailed (as defined in 29 CFR 1.2)for this classification in the survey or that the rate was derived by computing a weighted average rate based on all the rates reported in the survey for that classification.As a weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SUFL2022-007 6/27/2024.SU indicates the rate is a single non-union prevailing rate or a weighted average of survey data for that classification. FL indicates the State of Florida. 2022 is the year of the survey on which these classifications and rates are based.The next number,007 in the example, is an internal number used in producing the wage determination.The date, 6/27/2024 in the example, indicates the survey completion date for the classifications and rates under that identifier. ?SU?wage rates typically remain in effect until a new survey is conducted. However,the Wage and Hour Division (WHD) has the discretion to update such rates under 29 CFR 1.6(c)(1). State Adopted Rate Identifiers The ""SA"" identifier indicates that the classifications and prevailing wage rates set by a state(or local)government were adopted under 29 C.F.R 1.3(g)-(h). Example:SAME2023-007 01/03/2024.SA reflects that the rates are state adopted. ME refers to the State of Maine. 2023 is the year during which the state completed the survey on which the listed classifications and rates are based.The next number, 007 in the example, is an Supplementary Conditions 00 73 00-9 CCIA Taxiway Echo Rehabilitation Rev 3/2023 Project No: 26122 internal number used in producing the wage determination. The date, 01/03/2024 in the example, reflects the date on which the classifications and rates under the ?SA?identifier took effect under state law in the state from which the rates were adopted. ----------------------------------------------------------- WAGE DETERMINATION APPEALS PROCESS 1) Has there been an initial decision in the matter?This can be: a) a survey underlying a wage determination b)an existing published wage determination c) an initial WHD letter setting forth a position on a wage determination matter d) an initial conformance(additional classification and rate) determination On survey related matters, initial contact, including requests for summaries of surveys, should be directed to the WHD Branch of Wage Surveys.

The intent of the contract is to provide for construction and completion, in every detail, of the work described. It is further intended that the Contractor shall furnish all labor, materials, equipment, tools, transportation, and supplies required to complete the work in accordance with the plans, specifications, and terms of the contract. 40-02 Alteration of work and quantities.The Owner reserves the right to make such changes in quantities and work as may be necessary or desirable to complete, in a satisfactory manner, the original intended work. Unless otherwise specified in the Contract, the Owner's Engineer or RPR shall be and is hereby authorized to make, in writing, such in-scope alterations in the work and variation of quantities as may be necessary to complete the work, provided such action does not represent a significant change in the character of the work. For purpose of this section, a significant change in character of work means: any change that is outside the current contract scope of work; any change (increase or decrease) in the total contract cost by more than 25%; or any change in the total cost of a major contract item by more than 25%. Work alterations and quantity variances that do not meet the definition of significant change in character of work shall not invalidate the contract nor release the surety. Contractor agrees to accept payment for such work alterations and quantity variances in accordance with Section 90, paragraph 90-03, Compensation for Altered Quantities. Should the value of altered work or quantity variance meet the criteria for significant change in character of work, such altered work and quantity variance shall be covered by a supplemental agreement. Supplemental agreements shall also require consent of the Contractor's surety and separate performance and payment bonds. If the Owner and the Contractor are unable to agree on a unit adjustment for any contract item that requires a supplemental agreement, the Owner reserves the right to terminate the contract with respect to the item and make other arrangements for its completion. 40-03 Omitted items. The Owner, the Owner's Engineer or the RPR may provide written notice to the Contractor to omit from the work any contract item that does not meet the definition of major contract item. Major contract items may be omitted by a supplemental agreement. Such omission of contract items shall not invalidate any other contract provision or requirement. Should a contract item be omitted or otherwise ordered to be non-performed, the Contractor shall be paid for all work performed toward completion of such item prior to the date of the order to omit such item. Payment for work performed shall be in accordance with Section 90, paragraph 90-04, Payment for Omitted Items. 40-04 Extra work. Should acceptable completion of the contract require the Contractor to perform an item of work not provided for in the awarded contract as previously modified by change order or supplemental agreement, Owner may issue a Change Order to cover the necessary extra work. Change orders for extra work shall contain agreed unit prices for performing the change order work in accordance with the requirements specified in the order, and shall contain any adjustment to the contract time that, in the RPR's opinion, is necessary for completion of the extra work. When determined by the RPR to be in the Owner's best interest, the RPR may order the Contractor to proceed with extra work as provided in Section 90, paragraph 90-05, Payment for Extra Work. Extra work that is necessary for acceptable completion of the project, but is not within the general scope of the work covered by the original contract shall be covered by a supplemental agreement as defined in Section 10, paragraph 10-59, Supplemental Agreement. If extra work is essential to maintaining the project critical path, RPR may order the Contractor to commence the extra work under a Time and Material contract method. Once sufficient detail is available to establish the level of effort necessary for the extra work, the Owner shall initiate a change order or supplemental agreement to cover the extra work. General Provisions 00 74 01- 15 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 Any claim for payment of extra work that is not covered by written agreement(change order or supplemental agreement)shall be rejected by the Owner. 40-05 Maintenance of traffic. It is the explicit intention of the contract that the safety of aircraft, as well as the Contractor's equipment and personnel, is the most important consideration. The Contractor shall maintain traffic in the manner detailed in the Construction Safety and Phasing Plan (CSPP). a. It is understood and agreed that the Contractor shall provide for the free and unobstructed movement of aircraft in the air operations areas (AOAs) of the airport with respect to their own operations and the operations of all subcontractors as specified in Section 80, paragraph 80-04, Limitation of Operations. It is further understood and agreed that the Contractor shall provide for the uninterrupted operation of visual and electronic signals (including power supplies thereto) used in the guidance of aircraft while operating to, from,and upon the airport as specified in Section 70, paragraph 70-15, Contractor's Responsibility for Utility Service and Facilities of Others. b. With respect to their own operations and the operations of all subcontractors, the Contractor shall provide marking, lighting, and other acceptable means of identifying personnel, equipment, vehicles, storage areas,and any work area or condition that may be hazardous to the operation of aircraft,fire-rescue equipment, or maintenance vehicles at the airport in accordance with the construction safety and phasing plan (CSPP) and the safety plan compliance document (SPCD). c. When the contract requires the maintenance of an existing road, street, or highway during the Contractor's performance of work that is otherwise provided for in the contract, plans, and specifications, the Contractor shall keep the road, street, or highway open to all traffic and shall provide maintenance as may be required to accommodate traffic. The Contractor, at their expense, shall be responsible for the repair to equal or better than preconstruction conditions of any damage caused by the Contractor's equipment and personnel. The Contractor shall furnish, erect, and maintain barricades,warning signs, flag person,and other traffic control devices in reasonable conformity with the Manual on Uniform Traffic Control Devices (MUTCD) (http://mutcd.fhwa.dot.gov/), unless otherwise specified. The Contractor shall also construct and maintain in a safe condition any temporary connections necessary for ingress to and egress from abutting property or intersecting roads, streets or highways. 40-06 Removal of existing structures. All existing structures encountered within the established lines, grades, or grading sections shall be removed by the Contractor, unless such existing structures are otherwise specified to be relocated, adjusted up or down,salvaged,abandoned in place, reused in the work or to remain in place. The cost of removing such existing structures shall not be measured or paid for directly, but shall be included in the various contract items. Should the Contractor encounter an existing structure (above or below ground) in the work for which the disposition is not indicated on the plans, the Resident Project Representative (RPR) shall be notified prior to disturbing such structure. The disposition of existing structures so encountered shall be immediately determined by the RPR in accordance with the provisions of the contract. Except as provided in Section 40, paragraph 40-07, Rights in and Use of Materials Found in the Work, it is intended that all existing materials or structures that may be encountered (within the lines, grades, or grading sections established for completion of the work) shall be used in the work as otherwise provided for in the contract and shall remain the property of the Owner when so used in the work. 40-07 Rights in and use of materials found in the work. Should the Contractor encounter any material such as (but not restricted to) sand, stone, gravel, slag, or concrete slabs within the established lines, grades, or grading sections, the use of which is intended by the terms of the contract to be embankment, the Contractor may at their own option either: a. Use such material in another contract item, providing such use is approved by the RPR and is in conformance with the contract specifications applicable to such use; or, b. Remove such material from the site, upon written approval of the RPR; or c. Use such material for the Contractor's own temporary construction on site; or, General Provisions 00 74 01- 16 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 d. Use such material as intended by the terms of the contract. Should the Contractor wish to exercise option a., b., or c., the Contractor shall request the RPR's approval in advance of such use. Should the RPR approve the Contractor's request to exercise option a., b., or c., the Contractor shall be paid for the excavation or removal of such material at the applicable contract price. The Contractor shall replace, at their expense, such removed or excavated material with an agreed equal volume of material that is acceptable for use in constructing embankment, backfills, or otherwise to the extent that such replacement material is needed to complete the contract work.The Contractor shall not be charged for use of such material used in the work or removed from the site. Should the RPR approve the Contractor's exercise of option a., the Contractor shall be paid, at the applicable contract price, for furnishing and installing such material in accordance with requirements of the contract item in which the material is used. It is understood and agreed that the Contractor shall make no claim for delays by reason of their own exercise of option a., b., or c. The Contractor shall not excavate, remove,or otherwise disturb any material, structure,or part of a structure which is located outside the lines, grades, or grading sections established for the work, except where such excavation or removal is provided for in the contract, plans, or specifications. 40-08 Final cleanup. Upon completion of the work and before acceptance and final payment will be made, the Contractor shall remove from the site all machinery, equipment, surplus and discarded materials, rubbish,temporary structures,and stumps or portions of trees.The Contractor shall cut all brush and woods within the limits indicated and shall leave the site in a neat and presentable condition.

END OF SECTION 40 General Provisions 00 74 01- 17 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 PAGE INTENTIONALLY LEFT BLANK General Provisions 00 74 01- 18 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 SECTION 50 CONTROL OF WORK 50-01 Authority of the Resident Project Representative (RPR). The RPR has final authority regarding the interpretation of project specification requirements. The RPR shall determine acceptability of the quality of materials furnished, method of performance of work performed, and the manner and rate of performance of the work. The RPR does not have the authority to accept work that does not conform to specification requirements. 50-02 Conformity with plans and specifications. All work and all materials furnished shall be in reasonably close conformity with the lines, grades, grading sections, cross-sections, dimensions, material requirements, and testing requirements that are specified (including specified tolerances) in the contract, plans, or specifications. If the RPR finds the materials furnished,work performed,or the finished product not within reasonably close conformity with the plans and specifications, but that the portion of the work affected will, in their opinion, result in a finished product having a level of safety, economy, durability, and workmanship acceptable to the Owner, the RPR will advise the Owner of their determination that the affected work be accepted and remain in place. The RPR will document the determination and recommend to the Owner a basis of acceptance that will provide for an adjustment in the contract price for the affected portion of the work. Changes in the contract price must be covered by contract change order or supplemental agreement as applicable. If the RPR finds the materials furnished, work performed,or the finished product are not in reasonably close conformity with the plans and specifications and have resulted in an unacceptable finished product, the affected work or materials shall be removed and replaced or otherwise corrected by and at the expense of the Contractor in accordance with the RPR's written orders. The term "reasonably close conformity" shall not be construed as waiving the Contractor's responsibility to complete the work in accordance with the contract, plans, and specifications. The term shall not be construed as waiving the RPR's responsibility to insist on strict compliance with the requirements of the contract, plans, and specifications during the Contractor's execution of the work, when, in the RPR's opinion, such compliance is essential to provide an acceptable finished portion of the work. The term "reasonably close conformity" is also intended to provide the RPR with the authority, after consultation with the Sponsor and FAA, to use sound engineering judgment in their determinations to accept work that is not in strict conformity, but will provide a finished product equal to or better than that required by the requirements of the contract, plans and specifications. The RPR will not be responsible for the Contractor's means, methods, techniques, sequences, or procedures of construction or the safety precautions incident thereto. 50-03 Coordination of contract, plans, and specifications. The contract, plans, specifications, and all referenced standards cited are essential parts of the contract requirements. If electronic files are provided and used on the project and there is a conflict between the electronic files and hard copy plans, the hard copy plans shall govern. A requirement occurring in one is as binding as though occurring in all. They are intended to be complementary and to describe and provide for a complete work. In case of discrepancy, calculated dimensions will govern over scaled dimensions; contract technical specifications shall govern over contract general provisions, plans, cited standards for materials or testing, and cited advisory circulars (ACs); contract general provisions shall govern over plans, cited standards for materials or testing, and cited ACs; plans shall govern over cited standards for materials or testing and cited ACs. If any paragraphs contained in the Special Provisions conflict with General Provisions or Technical Specifications,the Special Provisions shall govern. From time to time, discrepancies within cited testing standards occur due to the timing of the change, edits, and/or replacement of the standards. If the Contractor discovers any apparent discrepancy within standard test methods, the Contractor shall immediately ask the RPR for an interpretation and decision, and such decision shall be final. General Provisions 00 74 01- 19 MA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 The Contractor shall not take advantage of any apparent error or omission on the plans or specifications. In the event the Contractor discovers any apparent error or discrepancy, Contractor shall immediately notify the Owner or the designated representative in writing requesting their written interpretation and decision. 50-04 List of Special Provisions. See Special Provisions (Section 00 74 02) 50-05 Cooperation of Contractor. The Contractor shall be supplied with two hard copies or an electronic PDF of the plans and specifications.The Contractor shall have available on the construction site at all times one hardcopy each of the plans and specifications. Additional hard copies of plans and specifications may be obtained by the Contractor for the cost of reproduction. The Contractor shall give constant attention to the work to facilitate the progress thereof, and shall cooperate with the RPR and their inspectors and with other Contractors in every way possible.

If, in the Contractor's opinion, the Owner's assistance is needed to locate the utility service or facility or the presence of a representative of the Owner is desirable to observe the work, such advice should be included in the notification. Such notification shall be given by the most expeditious means to reach the utility owner's "Person to Contact" no later than two normal business days prior to the Contractor's commencement of operations in such general vicinity. The Contractor shall furnish a written summary of the notification to the RPR. The Contractor's failure to give the two days' notice shall be cause for the Owner to suspend the Contractor's operations in the general vicinity of a utility service or facility. Where the outside limits of an underground utility service have been located and staked on the ground, the Contractor shall be required to use hand excavation methods within 3 feet (1 m) of such outside limits at such points as may be required to ensure protection from damage due to the Contractor's operations. Should the Contractor damage or interrupt the operation of a utility service or facility by accident or otherwise, the Contractor shall immediately notify the proper authority and the RPR and shall take all reasonable measures to prevent further damage or interruption of service. The Contractor, in such events, shall cooperate with the utility service or facility owner and the RPR continuously until such damage has been repaired and service restored to the satisfaction of the utility or facility owner. The Contractor shall bear all costs of damage and restoration of service to any utility service or facility due to their operations whether due to negligence or accident. The Owner reserves the right to deduct such costs from any monies due or which may become due the Contractor, or their own surety. 70-16 Furnishing rights-of-way. The Owner will be responsible for furnishing all rights-of-way upon which the work is to be constructed in advance of the Contractor's operations. 70-17 Personal liability of public officials. In carrying out any of the contract provisions or in exercising any power or authority granted by this contract, there shall be no liability upon the Engineer, RPR, their authorized representatives, or any officials of the Owner either personally or as an official of the Owner. It is understood that in such matters they act solely as agents and representatives of the Owner. 70-18 No waiver of legal rights. Upon completion of the work, the Owner will expeditiously make final inspection and notify the Contractor of final acceptance. Such final acceptance, however,shall not preclude or stop the Owner from correcting any measurement, estimate, or certificate made before or after completion of the work, nor shall the Owner be precluded or stopped from recovering from the Contractor or their surety, or both, such overpayment as may be sustained, or by failure on the part of the Contractor to fulfill their obligations under the contract. A waiver on the part of the Owner of any breach of any part of the contract shall not be held to be a waiver of any other or subsequent breach. The Contractor,without prejudice to the terms of the contract, shall be liable to the Owner for latent defects, fraud, or such gross mistakes as may amount to fraud, or as regards the Owner's rights under any warranty or guaranty. 70-19 Environmental protection. The Contractor shall comply with all federal, state, and local laws and regulations controlling pollution of the environment. The Contractor shall take necessary precautions to prevent pollution of streams, lakes, ponds, and reservoirs with fuels, oils, asphalts, chemicals, or other harmful materials and to prevent pollution of the atmosphere from particulate and gaseous matter.

No allowance will be made for anticipated profits. The period of shutdown shall be computed from the effective date of the written order to suspend work to the effective date of the written order to resume the work. Claims for such compensation shall be filed with the RPR within the time period stated in the RPR's order to resume work. The Contractor shall submit with their own claim information substantiating the amount shown on the claim. The RPR will forward the Contractor's claim to the Owner for consideration in accordance with local laws or ordinances. No provision of this article shall be construed as entitling the Contractor to compensation for delays due to inclement weather or for any other delay provided for in the contract, plans, or specifications. If it becomes necessary to suspend work for an indefinite period, the Contractor shall store all materials in such manner that they will not become an obstruction nor become damaged in any way. The Contractor shall take every precaution to prevent damage or deterioration of the work performed and provide for normal drainage of the work.The Contractor shall erect temporary structures where necessary to provide for traffic on, to, or from the airport. 80-07 Determination and extension of contract time.

END OF SECTION 80 General Provisions 00 74 01-39 MA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 PAGE INTENTIONALLY LEFT BLANK General Provisions 00 74 01-40 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 SECTION 90 MEASUREMENT AND PAYMENT 90-01 Measurement of quantities. All work completed under the contract will be measured by the RPR, or their authorized representatives, using United States Customary Units of Measurement. The method of measurement and computations to be used in determination of quantities of material furnished and of work performed under the contract will be those methods generally recognized as conforming to good engineering practice. Unless otherwise specified, longitudinal measurements for area computations will be made horizontally, and no deductions will be made for individual fixtures (or leave-outs) having an area of 9 square feet (0.8 square meters) or less. Unless otherwise specified, transverse measurements for area computations will be the neat dimensions shown on the plans or ordered in writing by the RPR. Unless otherwise specified,all contract items which are measured by the linear foot such as electrical ducts, conduits, pipe culverts, underdrains, and similar items shall be measured parallel to the base or foundation upon which such items are placed. The term"lump sum"when used as an item of payment will mean complete payment for the work described in the contract. When a complete structure or structural unit (in effect, "lump sum"work) is specified as the unit of measurement, the unit will be construed to include all necessary fittings and accessories. When requested by the Contractor and approved by the RPR in writing, material specified to be measured by the cubic yard (cubic meter) may be weighed, and such weights will be converted to cubic yards (cubic meters)for payment purposes. Factors for conversion from weight measurement to volume measurement will be determined by the RPR and shall be agreed to by the Contractor before such method of measurement of pay quantities is used. MEASUREMENT AND PAYMENT TERMS Term Description Excavation and In computing volumes of excavation, the average end area method will be used Embankment unless otherwise specified. Volume Measurement and The term "ton" will mean the short ton consisting of 2,000 pounds avoirdupois. All Proportion by materials that are measured or proportioned by weights shall be weighed on Weight accurate, independently certified scales by competent, qualified personnel at locations designated by the RPR. If material is shipped by rail, the car weight may be accepted provided that only the actual weight of material is paid for. However, car weights will not be acceptable for material to be passed through mixing plants. Trucks used to haul material being paid for by weight shall be weighed empty daily at such times as the RPR directs, and each truck shall bear a plainly legible identification mark. Measurement by Materials to be measured by volume in the hauling vehicle shall be hauled in Volume approved vehicles and measured therein at the point of delivery. Vehicles for this purpose may be of any size or type acceptable for the materials hauled, provided that the body is of such shape that the actual contents may be readily and accurately determined. All vehicles shall be loaded to at least their water level capacity, and all loads shall be leveled when the vehicles arrive at the point of delivery. Asphalt Material Asphalt materials will be measured by the gallon or ton. When measured by volume, such volumes will be measured at 60°F (16°C) or will be corrected to the volume at 60OF (16°C)using ASTM D1250 for asphalts. Net certified scale weights or weights based on certified volumes in the case of rail shipments will be used as a basis of measurement,subject to correction when asphalt material has been lost General Provisions 00 74 01-41 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 Term Description from the car or the distributor, wasted, or otherwise not incorporated in the work. When asphalt materials are shipped by truck or transport, net certified weights by volume, subject to correction for loss or foaming, will be used for computing quantities. Cement Cement will be measured by the ton or hundredweight. Structure Structures will be measured according to neat lines shown on the plans or as altered to fit field conditions. Timber Timber will be measured by the thousand feet board measure (MFBM) actually incorporated in the structure. Measurement will be based on nominal widths and thicknesses and the extreme length of each piece. Plates and Sheets The thickness of plates and galvanized sheet used in the manufacture of corrugated metal pipe, metal plate pipe culverts and arches, and metal cribbing will be specified and measured in decimal fraction of inch. Miscellaneous When standard manufactured items are specified such as fence, wire, plates, Items rolled shapes, pipe conduit, etc., and these items are identified by gauge, unit weight, section dimensions, etc., such identification will be considered to be nominal weights or dimensions. Unless more stringently controlled by tolerances in cited specifications, manufacturing tolerances established by the industries involved will be accepted. Scales Scales must be tested for accuracy and serviced before use. Scales for weighing materials which are required to be proportioned or measured and paid for by weight shall be furnished, erected, and maintained by the Contractor, or be certified permanently installed commercial scales. Platform scales shall be installed and maintained with the platform level and rigid bulkheads at each end. Scales shall be accurate within 0.5% of the correct weight throughout the range of use. The Contractor shall have the scales checked under the observation of the RPR before beginning work and at such other times as requested. The intervals shall be uniform in spacing throughout the graduated or marked length of the beam or dial and shall not exceed 0.1% of the nominal rated capacity of the scale, but not less than one pound. The use of spring balances will not be permitted. In the event inspection reveals the scales have been "overweighing" (indicating more than correct weight)they will be immediately adjusted. All materials received subsequent to the last previous correct weighting-accuracy test will be reduced by the percentage of error in excess of 0.5%. In the event inspection reveals the scales have been under-weighing (indicating less than correct weight), they shall be immediately adjusted. No additional payment to the Contractor will be allowed for materials previously weighed and recorded. Beams, dials, platforms, and other scale equipment shall be so arranged that the operator and the RPR can safely and conveniently view them. Scale installations shall have available ten standard 50-pound weights for testing the weighing equipment or suitable weights and devices for other approved equipment. All costs in connection with furnishing, installing, certifying, testing, and maintaining scales;for furnishing check weights and scale house; and for all other items specified in this subsection, for the weighing of materials for proportioning General Provisions 00 74 01-42 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport AC 150/5370-10H CCIA Taxiway Echo Rehabilitation 12/21/2018 Term Description or payment, shall be included in the unit contract prices for the various items of the project. Rental Equipment Rental of equipment will be measured by time in hours of actual working time and necessary traveling time of the equipment within the limits of the work. Special equipment ordered in connection with extra work will be measured as agreed in the change order or supplemental agreement authorizing such work as provided in paragraph 90-05 Payment for Extra Work. Pay Quantities When the estimated quantities for a specific portion of the work are designated as the pay quantities in the contract, they shall be the final quantities for which payment for such specific portion of the work will be made, unless the dimensions of said portions of the work shown on the plans are revised by the RPR. If revised dimensions result in an increase or decrease in the quantities of such work, the final quantities for payment will be revised in the amount represented by the authorized changes in the dimensions. 90-02 Scope of payment. The Contractor shall receive and accept compensation provided for in the contract as full payment for furnishing all materials, for performing all work under the contract in a complete and acceptable manner, and for all risk, loss, damage, or expense of whatever character arising out of the nature of the work or the execution thereof, subject to the provisions of Section 70, paragraph 70-18, No Waiver of Legal Rights. When the "basis of payment" subsection of a technical specification requires that the contract price (price bid) include compensation for certain work or material essential to the item, this same work or material will not also be measured for payment under any other contract item which may appear elsewhere in the contract, plans, or specifications. 90-03 Compensation for altered quantities. When the accepted quantities of work vary from the quantities in the proposal, the Contractor shall accept as payment in full, so far as contract items are concerned, payment at the original contract price for the accepted quantities of work actually completed and accepted. No allowance, except as provided for in Section 40, paragraph 40-02,Alteration of Work and Quantities, will be made for any increased expense, loss of expected reimbursement, or loss of anticipated profits suffered or claimed by the Contractor which results directly from such alterations or indirectly from their own unbalanced allocation of overhead and profit among the contract items, or from any other cause. 90-04 Payment for omitted items. As specified in Section 40, paragraph 40-03, Omitted Items, the RPR shall have the right to omit from the work (order nonperformance) any contract item, except major contract items, in the best interest of the Owner. Should the RPR omit or order nonperformance of a contract item or portion of such item from the work, the Contractor shall accept payment in full at the contract prices for any work actually completed and acceptable prior to the RPR's order to omit or non-perform such contract item. Acceptable materials ordered by the Contractor or delivered on the work prior to the date of the RPR's order will be paid for at the actual cost to the Contractor and shall thereupon become the property of the Owner. In addition to the reimbursement hereinbefore provided, the Contractor shall be reimbursed for all actual costs incurred for the purpose of performing the omitted contract item prior to the date of the RPR's order. Such additional costs incurred by the Contractor must be directly related to the deleted contract item and shall be supported by certified statements by the Contractor as to the nature the amount of such costs. 90-05 Payment for extra work. Extra work, performed in accordance with Section 40, paragraph 40-04, Extra Work, will be paid for at the contract prices or agreed prices specified in the change order or supplemental agreement authorizing the extra work.

Contractors employing apprentices or trainees under approved programs shall maintain written evidence of the registration of apprenticeship programs and certification of trainee programs, the registration of the apprentices and trainees, and the ratios and wage rates prescribed in the applicable programs and basic records relating thereto shall be maintained by the contractor during the course of the work and preserved for a period of three years thereafter for all laborers and mechanics working at the site of the work. Such records shall contain the name, address,and social security number of each such worker, his or her correct classification, hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in 1(b)(2)(B)of the Davis-Bacon Act); daily and weekly number of hours worked, deductions made and actual wages paid. Whenever the Secretary of Labor has found under 29 CFR 5.5(a)(1)(iv) that the wages of any laborer or mechanic include the amount of any costs reasonably anticipated in providing benefits under a plan or program described in section 1(b)(2)(B)of the Davis-Bacon Act, the contractor shall maintain records which show that the commitment to provide such benefits is enforceable, that the plan or program is financially responsible, and that the plan or program has been communicated in writing to the laborers or mechanics affected, and records which show the costs anticipated or the actual costs incurred in providing such benefits. Contractors employing apprentices or trainees under approved programs shall maintain written evidence of the registration of apprenticeship programs and certification of trainee programs, the registration of the apprentices and trainees, and the ratios and wage rates prescribed in the applicable programs. (A) The Contractor shall submit weekly for each week in which any contract work is performed a copy of all payrolls to the Federal Aviation Administration if the agency is a party to the contract, but if the agency is not such a party, the Contractor will submit the payrolls to the applicant, Sponsor, or Owner, as the case may be, for transmission to the Federal Aviation Administration. The payrolls submitted shall set out accurately and completely all of the information required to be maintained under 29 CFR § 5.5(a)(3)(i), except that full social security numbers and home addresses shall not be included on weekly transmittals. Instead, the payrolls shall only need to include an individually identifying number for each employee (e.g., the last four digits of the employee's social security number). The required weekly payroll information may be submitted in any form desired. Optional Form WH-347 is available for this purpose from the Wage and Hour Special Provisions 00 74 02-9 MA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport CCIA Taxiway Echo Rehabilitation Division Web site at https://www.dol.gov/agencies/whd/government- contracts/construction/payroll-certification or its successor site. The prime contractor is responsible for the submission of copies of payrolls by all subcontractors. Contractors and subcontractors shall maintain the full social security number and current address of each covered worker and shall provide them upon request to the Federal Aviation Administration if the agency is a party to the contract, but if the agency is not such a party, the Contractor will submit them to the applicant, Sponsor, or Owner, as the case may be, for transmission to the Federal Aviation Administration, the Contractor, or the Wage and Hour Division of the Department of Labor for purposes of an investigation or audit of compliance with prevailing wage requirements. It is not a violation of this section for a prime contractor to require a subcontractor to provide addresses and social security numbers to the prime contractor for its own records, without weekly submission to the sponsoring government agency (or the applicant, Sponsor, or Owner). (B) Each payroll submitted shall be accompanied by a"Statement of Compliance,"signed by the Contractor or subcontractor or his or her agent who pays or supervises the payment of the persons employed under the contract and shall certify the following: (1) That the payroll for the payroll period contains the information required to be provided under 29 CFR § 5.5(a)(3)(ii), the appropriate information is being maintained under 29 CFR § 5.5 (a)(3)(i) and that such information is correct and complete; (2) That each laborer and mechanic (including each helper, apprentice and trainee) employed on the contract during the payroll period has been paid the full weekly wages earned, without rebate, either directly or indirectly, and that no deductions have been made either directly or indirectly from the full wages earned, other than permissible deductions as set forth in Regulations 29 CFR Part 3; (3) That each laborer or mechanic has been paid not less than the applicable wage rates and fringe benefits or cash equivalents for the classification of work performed, as specified in the applicable wage determination incorporated into the contract. (C) The weekly submission of a properly executed certification set forth on the reverse side of Optional Form WH-347 shall satisfy the requirement for submission of the "Statement of Compliance" required by paragraph (3)(ii)(B) of this section. (D) The falsification of any of the above certifications may subject the Contractor or subcontractor to civil or criminal prosecution under Section 1001 of Title 18 and Section 231 of the United States Code. (iii) The contractor or subcontractor shall make the records required under paragraph (3)(i) of this section available for inspection, copying or transcription by authorized representatives of the sponsor, the Federal Aviation Administration, or the Department of Labor, and shall permit such representatives to interview employees during working hours on the job. If the contractor or subcontractor fails to submit the required records or to make them available, the Federal agency may, after written notice to the contractor, sponsor, applicant or owner, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds. Furthermore, failure to submit the required records upon request or to make such records available may be grounds for debarment action pursuant to 29 CFR § 5.12. 4. Apprentices and Trainees (i) Apprentices.Apprentices will be permitted to work at less than the predetermined rate for the work they performed when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the U.S. Department of Labor, Special Provisions 00 74 02- 10 MA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport CCIA Taxiway Echo Rehabilitation Employment and Training Administration, Office of Apprenticeship Training, Employer and Labor Services, or with a State Apprenticeship Agency recognized by the Office, or if a person is employed in his or her first 90 days of probationary employment as an apprentice in such an apprenticeship program, who is not individually registered in the program, but who has been certified by the Office of Apprenticeship Training, Employer and Labor Services or a State Apprenticeship Agency (where appropriate) to be eligible for probationary employment as an apprentice. The allowable ratio of apprentices to journeymen on job site in any craft classification shall not be greater than the ratio permitted to the contractor as to the entire work force under the registered program. Any worker listed on a payroll at an apprentice wage rate, who is not registered or otherwise employed as stated above, shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. Where a contractor is performing construction on a project in a locality other than that in which its program is registered, the ratios and wage rates (expressed in percentages of the journeyman's hourly rate) specified in the Contractor's or subcontractor's registered program shall be observed. Every apprentice must be paid at not less than the rate specified in the registered program for the apprentice's level of progress, expressed as a percentage of the journeymen hourly rate specified in the applicable wage determination. Apprentices shall be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the apprenticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage determination for the applicable classification. If the Administrator determines that a different practice prevails for the applicable apprentice classification, fringes shall be paid in accordance with that determination. In the event the Office of Apprenticeship Training, Employer and Labor Services, or a State Apprenticeship Agency recognized by the Office,withdraws approval of an apprenticeship program, the Contractor will no longer be permitted to utilize apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is approved. (ii) Trainees. Except as provided in 29 CFR § 5.16, trainees will not be permitted to work at less than the predetermined rate for the work performed unless they are employed pursuant to and individually registered in a program which has received prior approval, evidenced by formal certification by the U.S. Department of Labor, Employment and Training Administration. The ratio of trainees to journeymen on the job site shall not be greater than permitted under the plan approved by the Employment and Training Administration. Every trainee must be paid at no less than the rate specified in the approved program for the trainee's level of progress, expressed as a percentage of the journeyman hourly rate specified in the applicable wage determination. Trainees shall be paid fringe benefits in accordance with the provisions of the trainee program. If the trainee program does not mention fringe benefits, trainees shall be paid the full amount of fringe benefits listed on the wage determination unless the Administrator of the Wage and Hour Division determines that there is an apprenticeship program associated with the corresponding journeyman wage rate on the wage determination that provides for less than full fringe benefits for apprentices. Any employee listed on the payroll at a trainee rate that is not registered and participating in a training plan approved by the Employment and Training Administration shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any trainee performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. In the event the Employment and Training Administration withdraws approval of a training program, the Contractor will no longer be permitted to utilize trainees at less than the applicable predetermined rate for the work performed until an acceptable program is approved.

The Owner and/or Engineer will call such coordination conferences as may seem expedient to him for the purpose of assuring coordination of the work covered by this Contract.The Contractor shall attend all such conferences. This in no way relieves the Contractor of his responsibility to fully coordinate his work under this Contract. C-05 EXTENSIONS OF TIME Extensions of time for completion, under the condition of 3(a) next below, will be granted; extensions may be granted under other stated conditions: 1. If the satisfactory execution and completion of the Contract shall require work or material in greater amounts or quantities than those set forth in the Contract, then the Contract time shall be increased in the same proportion as the additional work bears to the original work contracted for. C-01.1 2.An average or usual number of inclement weather days, when work cannot proceed, is to be anticipated during the construction period and is not to be considered as warranting extension of time. See See Section 00 725 00 General Conditions and 00 73 00 Supplementary Conditions. 3. Should the work under the Contract be delayed by other causes which could not have been prevented or contemplated by the Contractor, and which are beyond the Contractor's power to prevent or remedy, an extension of time may be granted. Such causes of delay shall include but not necessarily be limited to the following: a. Acts of God, acts of the public enemy, acts of the Owner except as provided in these Specifications, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and unusually severe weather. b. Any delays of Subcontractors or suppliers occasioned by any of the causes specified above. The Engineer or other authorized representative of the Owner shall keep a written record sufficient for determination as to the inclusion of that day in the computation of Contract time.This record shall be available for examination by the Contractor during normal hours of work as soon as feasible after the first of each Special Provisions 00 74 02-26 CCIA Taxiway Echo Rehabilitation Project No: Project No:26122 Corpus Christi International Airport CCIA Taxiway Echo Rehabilitation construction month.Weather reporting locations and procedures shall be discussed during the preconstruction meeting. In case of disagreement between the representative of the Owner and the Contractor, as to the classification of any day, the matter shall be referred to the Owner whose decision shall be final. The Contractor shall provide notice to the Engineer each week, in the form of written letter or e-mail, to document weather and site conditions and request certain days be deemed non-conducive due to weather or site conditions. At a minimum, reports shall contain average temperature, 24 hour rainfall and information source.The notice shall be received by the Engineer's representative by the close of business of each Tuesday for the previous week of contract time. Failure to provide the written documentation by the close of business each Tuesday shall result in all seven days of the previous week being deemed conducive.These notices shall serve as justification for whether or not an extension of time is granted, if merited. In case of disagreement between the representative of the Owner and the Contractor,as to the classification of any day,the matter shall be referred to the Owner whose decision shall be final. If the Contractor finds it impossible for reasons beyond his control to complete the work within the Contract time as specified,or as extended in accordance with the provisions of this subsection, he may, at any time prior to the expiration of the Contract time as extended, make a written request to the Engineer for an extension of time setting forth the reasons which he believes will justify the granting of his request. The Contractor's plea that insufficient time was specified is not a valid reason for extension of time. If the Engineer finds that the work was delayed because of conditions beyond the control and without the fault of the Contractor, he may recommend to the Owner that the contract time be extended as conditions justify. If the Owner extends the contract, the extended time for completion shall then be in full force and effect, the same as though it were the original time for completion. The amount of all extensions of time for whatever reason granted shall be determined by the Owner. In general, only actual and not hypothetical days of delay will be considered. The Owner shall have authority to grant additional extensions of time as the Owner may deem justifiable.

Contractor shall coordinate with the Owner on all testing. Tests will also be performed as each new area of construction is started. F. Another option for disposal of groundwater by Contractor would include pumping to the nearest wastewater system. If discharging to temporary holding tanks and trucking to a wastewater or wastewater plant, the costs for these operations shall be negotiated. Other groundwater disposal alternatives or solutions may be approved by the Designer on a case by case basis. G. Prior to pumping groundwater from a trench to the wastewater system the Contractor shall contact Wastewater Pre-treatment Coordinator at 826-1817 to obtain a "no cost" permit from the Owner's Waste Water Department. Contractor will pay for any water quality testing or water analysis cost required. The permit will require an estimate of groundwater flow.

Should conflicts arise between manufacturer's recommendations and this specification, they shall be brought to the attention of the Engineer. B. Tack coat shall not be placed when weather conditions are unsuitable in the opinion of the Engineer. Air and pavement temperatures shall be sufficient to allow the asphalt tack coat to hold the geotextile in place. Air temperature shall be 10°C (50°F) and rising for asphalt cement tack coats. Air temperature shall be 15°C (50°F)for asphalt emulsion tack coats are used. City Project No: 26122 Issue For Bids SS-221-5 Garver Project No. 2502477 Corpus Christi International Airport Taxiway Echo Rehabilitation C. The specified rate of tack coat application must be sufficient to satisfy the asphalt retention properties of the geotextile and bond the geotextile and overlay to the old pavement. D. When emulsions are used, the application rate must be increased to offset water content of the emulsion. E. Application of the tack coat shall be by distributor spray bar, with hand spraying kept to a minimum. Temperature of the asphalt sealant shall be sufficiently high to permit uniform spray pattern. For asphalt cements the minimum temperature shall be 150°C (300°F). To avoid damage to the geotextile, however, the distributor tank temperatures shall not exceed 160°C (320°F). F. A spray pattern for asphalt emulsion is improved by heating. Temperatures in the 55°C (130°F) to 70°C(160°F)range are desirable. A temperature of 70°C(160°F)shall not be exceeded since higher temperatures may break emulsion. G. The target width of asphalt tack coat application shall be the geotextile width plus 150 mm (6 in). The asphalt tack coat shall not be applied any farther in advance of geotextile placement than the distance the Contractor can maintain free of traffic. H. Asphalt spills shall be cleaned from the pavement surface to avoid flushing and geotextile movement. I. When asphalt emulsions are used, the emulsion shall be cured prior to placing the geotextile and final wearing surface. This means essentially no moisture remaining. 3.3 INSTALLATION OF GEOTEXTILE PAVING FABRIC A. The geotextile shall be installed per manufacturers recommendations and the requirements of this specifications. Should conflicts arise between manufacturers recommendations and this specification, they shall be brought to the attention of the Engineer. B. The geotextile shall not be placed when weather conditions are unsuitable in the opinion of the Engineer. Air and pavement temperatures shall be sufficient to allow the asphalt tack coat to hold the geotextile in place. For geotextiles installed in conjunction with asphalt cement tack coats, air temperature shall be 10'C (50°F) and rising. Air temperature shall be 15°C (50°F) where asphalt emulsions are used. C. The geotextile shall be placed onto the asphalt tack coat (calendared or smooth side up) with minimum wrinkling prior to the time the asphalt has cooled and lost tackiness. As directed by the Engineer, wrinkles or folds in excess of 25 mm (1 in) shall be slit and laid flat. D. Blooming and/or pneumatic rolling will be required to maximize geotextile contact with the pavement surface. E. Overlap of geotextile joints shall be sufficient to ensure full closure of the joint, but should not exceed 150 mm. Transverse joints shall be lapped in the direction of paving to prevent edge pickup by the paver. A second application of asphalt tack coat to the geotextile overlaps will be City Project No: 26122 Issue For Bids SS-221-6 Garver Project No. 2502477 Corpus Christi International Airport Taxiway Echo Rehabilitation required if in the judgement of the Engineer additional asphalt tack coat is needed to ensure proper bonding of the double geotextile layer. F. Placement of the hot-mix overlay should closely follow geotextile laydown. The asphalt overlay should be placed the same day the paving fabric is installed. The temperature of the overlay mix shall not exceed 160°C (3200F). G. In the event asphalt bleeds through the geotextile causing construction problems before the overlay is placed, the affected areas shall be blotted by spreading sand. H. To avoid movement of, or damage to the tack-coat saturated geotextile, turning of the paver and other vehicles shall be gradual and kept to a minimum. I.

When the specifications provide for acceptance of material based on the method of estimating percentage of material within specification limits (PWL), the PWL will be determined in accordance with this section. All test results for a lot will be analyzed statistically to determine the total estimated percent of the lot that is within specification limits. The PWL is computed using the sample average (X) and sample standard deviation (Sn) of the specified number (n) of sublots for the lot and the specification tolerance limits, L for lower and U for upper, for the particular acceptance parameter. From these values, the respective Quality index, QL for Lower Quality Index and/or Qu for Upper Quality Index, is computed and the PWL for the lot for the specified n is determined from Table 1. All specification limits specified in the technical sections shall be absolute values. Test results used in the calculations shall be to the significant figure given in the test procedure. There is some degree of uncertainty(risk)in the measurement for acceptance because only a small fraction of production material (the population) is sampled and tested. This uncertainty exists because all portions of the production material have the same probability to be randomly sampled. The Contractor's risk is the probability that material produced at the acceptable quality level is rejected or subjected to a pay adjustment. The Owner's risk is the probability that material produced at the rejectable quality level is accepted. It is the intent of this section to inform the Contractor that, in order to consistently offset the Contractor's risk for material evaluated, production quality(using population average and population standard deviation) must be maintained at the acceptable quality specified or higher. In all cases, it is the responsibility of the Contractor to produce at quality levels that will meet the specified acceptance criteria when sampled and tested at the frequencies specified. 110-2 Method for computing PWL. The computational sequence for computing PWL is as follows: a. Divide the lot into n sublots in accordance with the acceptance requirements of the specification. b. Locate the random sampling position within the sublot in accordance with the requirements of the specification. c. Make a measurement at each location, or take a test portion and make the measurement on the test portion in accordance with the testing requirements of the specification. d. Find the sample average (X)for all sublot test values within the lot by using the following formula: X= (X1 +X2 +X3+ . . An)/ n Where: X = Sample average of all sublot test values within a lot x1, x2,. . .xn= Individual sublot test values n = Number of sublot test values e. Find the sample standard deviation (Sn) by use of the following formula: Sn = [(d12 + d22 + d32 + . . Ant)/(n-1)]v2 Where: Sn = Sample standard deviation of the number of sublot test values in the set d1, d2, . . .dn = Deviations of the individual sublot test values x1, x2, ... from the average value X that is: d1 = (x1 -X), d2 = (X2-X) ... do = (Xn -X) n = Number of sublot test values City Project No: 26122 Issue For Bids C-110-1 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 f. For single sided specification limits (i.e., L only), compute the Lower Quality Index QL by use of the following formula: QL= (X- L)/S„ Where: L = specification lower tolerance limit Estimate the percentage of material within limits (PWL) by entering Table 1 with QL, using the column appropriate to the total number(n) of measurements. If the value of QL falls between values shown on the table, use the next higher value of PWL. g. For double-sided specification limits (i.e., L and U), compute the Quality Indexes QL and Qu by use of the following formulas: QL= (X- L)/S„ and QU = (U -X)/S„ Where: L and U = specification lower and upper tolerance limits Estimate the percentage of material between the lower (L) and upper (U) tolerance limits (PWL) by entering Table 1 separately with QL and Qu, using the column appropriate to the total number (n) of measurements, and determining the percent of material above PL and percent of material below Pu for each tolerance limit. If the values of QL fall between values shown on the table, use the next higher value of PL or Pu. Determine the PWL by use of the following formula: PWL= (Pu + PL) - 100 Where: PL= percent within lower specification limit Pu = percent within upper specification limit City Project No: 26122 Issue For Bids C-110-2 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 EXAMPLE OF PWL CALCULATION Project: Example Project Test Item: Item P-401, Lot A.

All material excavated shall be classified as defined below: a. Unclassified excavation. Unclassified excavation shall consist of the excavation and disposal of all material, regardless of its nature. 152-1.3 Unsuitable excavation. Unsuitable material shall be disposed in designated off-site waste areas or as directed by the Engineer. Materials containing vegetable or organic matter, such as muck, peat, organic silt, or sod shall be considered unsuitable for use in embankment construction. Material suitable for topsoil may be used on the embankment slope when approved by the RPR. Undercutting of material unsatisfactory for subgrade foundation, roads, shoulders, or areas intended for turfing shall be considered unsuitable excavation and shall be excavated to the depth specified by the Engineer below the subgrade. CONSTRUCTION METHODS 152-2.1 General. BefGFe beginning excavation, gFading, and embankment opeFations in any aFea, the area shallTea-red-or eleared and grubbed on aGGOFdanee-with-item r. The suitability of material to be placed in embankments shall be subject to approval by the RPR. All unsuitable material shall be disposed of in waste areas as shown on the plans. All waste areas shall be graded to allow positive drainage of the area and adjacent areas. The surface elevation of waste areas shall be specified on the plans or approved by the RPR. When the Contractor's excavating operations encounter artifacts of historical or archaeological significance, the operations shall be temporarily discontinued and the RPR notified per Section 70, paragraph 70-20. At the direction of the RPR,the Contractor shall excavate the site in such a manner as to preserve the artifacts encountered and allow for their removal. Such excavation will be paid for as extra work. Areas outside the limits of the pavement areas where the top layer of soil has become compacted by hauling or other Contractor activities shall be scarified and disked to a depth of 4 inches, to loosen and pulverize the soil. Stones or rock fragments larger than two(2)-inches 4 R;Ghea in their greatest dimension will not be permitted in the top 6 inches of the subgrade or top 4 inches of areas to be returned to preconstruction condition. If it is necessary to interrupt existing surface drainage, sewers or under-drainage, conduits, utilities, or similar underground structures, the Contractor shall be responsible for and shall take all necessary precautions to preserve them or provide temporary services. When such facilities are encountered, the Contractor shall notify the RPR, who shall arrange for their removal if necessary. The Contractor, at their own expense, shall satisfactorily repair or pay the cost of all damage to such facilities or structures that may result from any of the Contractor's operations during the period of the contract. a. Blasting. Blasting shall not be allowed. 152-2.2 Excavation. No excavation shall be started until the work has been staked out by the Contractor and the RPR has obtained from the Contractor, the survey notes of the elevations and measurements of the ground surface. The Contractor and RPR shall agree that the original ground lines shown on the original topographic mapping are accurate, or agree to any adjustments made to the original ground lines. Digital terrain model (DTM)files of the existing surfaces, finished surfaces and other various surfaces were used to develop the design plans. City Project No: 26122 Issue For Bids P-152-1 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 All areas to be excavated shall be stripped of vegetation and topsoil. Topsoil shall be stockpiled for future use in areas designated on the plans or by the RPR. All suitable excavated material shall be used in the formation of embankment, subgrade, or other purposes as shown on the plans. All unsuitable material shall be disposed of as described in paragraph 152-1.3 shOWR on the plan The grade shall be maintained so that the surface is well drained at all times. When the volume of the excavation exceeds that required to construct the embankments to the grades as indicated on the plans, the excess shall be used to grade the areas of ultimate development or disposed as directed by the RPR. When the volume of excavation is not sufficient for constructing the embankments to the grades indicated, the deficiency shall be obtained from borrow areas. a. Selective grading.When the quality of material varies significantly seleGtive gr„ iRg ,s indi aced „R the plans, the more suitable material designated by the RPR shall be used in constructing the embankment or in capping the pavement subgrade. If, at the time of excavation, it is not possible to place this material in its final location, it shall be stockpiled in approved areas until it can be placed.The more suitable material shall then be placed and compacted as specified. Selective grading shall be considered incidental to the work involved. The cost of stockpiling and placing the material shall be included in the various pay items of work involved. Selective grading will not be measured for separate payment but will be considered subsidiary to "Unclassifed Excavation." b. Undercutting. Rock, shale, hardpan, loose rock, boulders, or other material unsatisfactory for safety areas, subgrades, roads, shoulders, or any areas intended for turf shall be excavated to a minimum depth of 12 inches below the subgrade or to the depth specified by the RPR. Muck, peat, matted roots, or other yielding material, unsatisfactory for subgrade foundation, shall be removed to the depth specified. Unsuitable materials shall be disposed of as directed in paragraph 152-1.3. This excavated material shall be paid for at the contract unit price per cubic yard for Unsuitable Excavation. The excavated area shall be backfilled with suitable material obtained from the grading operations or borrow areas and compacted to specified densities. The necessary backfill will constitute a necessary part of Unsuitable Excavation part of the emba.,L.,-8Rt Where rock cuts are made, backfill with select material. Any pockets created in the rock surface shall be drained in accordance with the details shown on the plans. Undercutting will be paid as Unsuitable Excavation. c. Over-break. Over-break, including slides, is that portion of any material displaced or loosened beyond the finished work as planned or authorized by the RPR. All over-break shall be graded or removed by the Contractor and disposed of as directed by the RPR. The RPR shall determine if the displacement of such material was unavoidable and their own decision shall be final. Payment will not be made for the removal and disposal of over-break that the RPR determines as avoidable. Unavoidable over-break will be classified as "Unclassified Excavation." d. Removal of utilities. The removal of existing structures and utilities required to permit the orderly progress of work will be accomplished by someone other than the Contractor. All existing foundations shall be excavated at least 2 feet below the top of subgrade or as indicated on the plans, and the material disposed of as directed by the RPR.All foundations thus excavated shall be backfilled with suitable material and compacted as specified for embankment or as shown on the plans. All work associated with the excavation, removal, backfill, disposal, and/or stockpiling of existing structures and culverts will not be measured for separate payment but will be considered subsidiary to "Unclassified Excavation" 152-2.3 Borrow excavation. Imported material for fill or backfill under pavements shall be homogenous, free from organics, and clay balls, and other deleterious materiasl and shall have a maximum liquid limit (LL) of 40 percent and a plasticity index (PI) between 7 and 18. The material shall have a minimum of 35 percent passing the No. 200 sieve, with no soil particles exceeding 1-112 inches. 152-2.4 Drainage excavation. Drainage excavation shall consist of excavating drainage ditches including intercepting, inlet, or outlet ditches; or other types as shown on the plans. The work shall be performed in City Project No: 26122 Issue For Bids P-152-2 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 sequence with the other construction. Ditches shall be constructed prior to starting adjacent excavation operations.All satisfactory material shall be placed in embankment fills; unsuitable material shall be placed in designated waste areas or as directed by the RPR. All necessary work shall be performed true to final line, elevation, and cross-section. The Contractor shall maintain ditches constructed on the project to the required cross-section and shall keep them free of debris or obstructions until the project is accepted. This item shall not be measured for separate payment as it shall be considered subsidiary to drainage installation and overall construction costs. 152-2.5 Preparation of cut areas or areas where existing pavement has been removed. In those areas on which a subbase or base course is to be placed, the top 12 inches of subgrade shall be compacted to not less than 100 % of maximum density for non-cohesive soils, and 95% of maximum density for cohesive soils as determined by ASTM D1557. As used in this specification, "non-cohesive" shall mean those soils having a plasticity index (PI) of less than 3 as determined by ASTM D4318. 152-2.6 Preparation of embankment area. All sod and vegetative matter shall be removed from the surface upon which the embankment is to be placed. The cleared surface shall be broken up by plowing or scarifying to a minimum depth of 6 inches and shall then be compacted per paragraph 152-2.10. Sloped surfaces steeper than one (1) vertical to four (4) horizontal shall be plowed, stepped, benched, or broken up so that the fill material will bond with the existing material. When the subgrade is part fill and part excavation or natural ground, the excavated or natural ground portion shall be scarified to a depth of 12 inches and compacted as specified for the adjacent fill. No direct payment shall be made for the work performed under this section. The necessary clearing and grubbing and the quantity of excavation removed will be paid for under the respective items of work. 152-2.7 Control Strip. The first half-day of construction of subgrade and/or embankment shall be considered as a control strip for the Contractor to demonstrate, in the presence of the RPR, that the materials, equipment, and construction processes meet the requirements of this specification. The sequence and manner of rolling necessary to obtain specified density requirements shall be determined. The maximum compacted thickness may be increased to a maximum of 12 inches upon the Contractor's demonstration that approved equipment and operations will uniformly compact the lift to the specified density. The RPR must witness this demonstration and approve the lift thickness prior to full production. Control strips that do not meet specification requirements shall be reworked, re-compacted, or removed and replaced at the Contractor's expense. Full operations shall not begin until the control strip has been accepted by the RPR. The Contractor shall use the same equipment, materials, and construction methods for the remainder of construction, unless adjustments made by the Contractor are approved in advance by the RPR. 152-2.8 Formation of embankments.The material shall be constructed in lifts as established in the control strip, but not less than 6 inches nor more than 12 inches of compacted thickness. When more than one lift is required to establish the layer thickness shown on the plans, the construction procedure described here shall apply to each lift. No lift shall be covered by subsequent lifts until tests verify that compaction requirements have been met. The Contractor shall rework, re-compact and retest any material placed which does not meet the specifications. The lifts shall be placed, to produce a soil structure as shown on the typical cross-section or as directed by the RPR. Materials such as brush, hedge, roots, stumps, grass and other organic matter, shall not be incorporated or buried in the embankment. Earthwork operations shall be suspended at any time when satisfactory results cannot be obtained due to rain, freezing, or other unsatisfactory weather conditions in the field. Frozen material shall not be placed in the embankment nor shall embankment be placed upon frozen material. Material shall not be placed on surfaces that are muddy, frozen, or contain frost. The Contractor shall drag, blade, or slope the embankment to provide surface drainage at all times. City Project No: 26122 Issue For Bids P-152-3 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 The material in each lift shall be within ±2% of optimum moisture content before rolling to obtain the prescribed compaction. The material shall be moistened or aerated as necessary to achieve a uniform moisture content throughout the lift. Natural drying may be accelerated by blending in dry material or manipulation alone to increase the rate of evaporation. The Contractor shall make the necessary corrections and adjustments in methods, materials or moisture content to achieve the specified embankment density. The RPR will take samples of excavated materials which will be used in embankment for testing and develop a Moisture-Density Relations of Soils Report(Proctor)in accordance with D 1557 .A new Proctor shall be developed for each soil type based on visual classification. Density tests will be taken by the Contractor for every 3,000 square yards of compacted embankment for each lift which is required to be compacted, or other appropriate frequencies as determined by the RPR. If the material has greater than 30% retained on the 3/4-inch (19.0 mm)sieve,follow AASHTO T-180 Annex Correction of maximum dry density and optimum moisture for oversized particles. Rolling operations shall be continued until the embankment is compacted to not less than 100% of maximum density for non-cohesive soils, and 95% of maximum density for cohesive soils as determined by ASTM D1557. Under all areas to be paved, the embankments shall be compacted to a depth of 12" and to a density of not less than 95 percent of the maximum density as determined by ASTM D1557. As used in this specification, "non-cohesive" shall mean those soils having a plasticity index (PI) of less than 3 as determined by ASTM D4318. On all areas outside of the pavement areas, no compaction will be required on the top 4 inches which shall be prepared for a seedbed in accordance with Item T-901. The in-place field density shall be determined in accordance with ASTM 6938 using Procedure A, the direct transmission method, and ASTM D6938 shall be used to determine the moisture content of the material. The machine shall be calibrated in accordance with ASTM D6938. The RPR shall perform all density tests. If the specified density is not attained, the area represented by the test or as designated by the RPR shall be reworked and/or re-compacted and additional random tests made. This procedure shall be followed until the specified density is reached. Compaction areas shall be kept separate, and no lift shall be covered by another lift until the proper density is obtained. During construction of the embankment, the Contractor shall route all construction equipment evenly over the entire width of the embankment as each lift is placed. Lift placement shall begin in the deepest portion of the embankment fill.As placement progresses,the lifts shall be constructed approximately parallel to the finished pavement grade line. When rock, concrete pavement, asphalt pavement, and other embankment material are excavated at approximately the same time as the subgrade, the material shall be incorporated into the outer portion of the embankment and the subgrade material shall be incorporated under the future paved areas. Stones, fragmentary rock, and recycled pavement larger than 4 inches in their greatest dimensions will not be allowed in the top 12 inches of the subgrade. Rockfill shall be brought up in lifts as specified or as directed by the RPR and the finer material shall be used to fill the voids forming a dense, compact mass. Rock, cement concrete pavement, asphalt pavement, and other embankment material shall not be disposed of except at places and in the manner designated on the plans or by the RPR. When the excavated material consists predominantly of rock fragments of such size that the material cannot be placed in lifts of the prescribed thickness without crushing, pulverizing or further breaking down the pieces,such material may be placed in the embankment as directed in lifts not exceeding 2 feet in thickness. Each lift shall be leveled and smoothed with suitable equipment by distribution of spalls and finer fragments of rock. The lift shall not be constructed above an elevation 4 feet below the finished subgrade. City Project No: 26122 Issue For Bids P-152-4 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 There will be no separate measurement of payment for compacted embankment. All costs incidental to placing in lifts, compacting, discing, watering, mixing, sloping, and other operations necessary for construction of embankments will be included in the contract price for excavation, borrow, or other items. 152-2.9 Proof rolling. The purpose of proof rolling the subgrade is to identify any weak areas in the subgrade and not for compaction of the subgrade. After compaction is completed, the subgrade area shall be proof rolled with a heavy pneumatic-tired roller having four or more tires abreast, each tire loaded to a minimum of 30,000-pounds and inflated to a 125 psi in the presence of the RPR. Apply a minimum of 50% coverage, or as specified by the RPR, under pavement areas. A coverage is defined as the application of one tire print over the designated area. Soft areas of subgrade that deflect more than 1 inch or show permanent deformation greater than 1 inch shall be removed and replaced with suitable material or reworked to conform to the moisture content and compaction requirements in accordance with these specifications. Removal and replacement of soft areas is incidental to this item. 152-2.10 Compaction requirements. The subgrade under areas to be paved shall be compacted to a depth of 12 inches and to a density of not less than 100 percent of the maximum dry density as determined by ASTM D1557 The subgrade in areas outside the limits of the pavement areas shall be compacted to a depth of 12 inches and to a density of not less than 95 percent of the maximum density as determined by ASTM 1557. The material to be compacted shall be within±2%of optimum moisture content before being rolled to obtain the prescribed compaction (except for expansive soils). When the material has greater than 30 percent retained on the 3/4 inch (19.0 mm) sieve, follow the methods in ASTM D1557 . Tests for moisture content and compaction will be taken at a minimum of 3,000-S.Y. of subgrade. All quality assurance testing shall be done by the RPR. The in-place field density shall be determined in accordance with ASTM D6938 using Procedure A, the direct transmission method, and ASTM D6938 shall be used to determine the moisture content of the material. The machine shall be calibrated in accordance with ASTM D6938 within 12 months prior to its use on this contract. The gage shall be field standardized daily. Maximum density refers to maximum dry density at optimum moisture content unless otherwise specified. If the specified density is not attained, the entire lot shall be reworked and/or re-compacted and additional random tests made. This procedure shall be followed until the specified density is reached. All cut-and-fill slopes shall be uniformly dressed to the slope, cross-section, and alignment shown on the plans or as directed by the RPR and the finished subgrade shall be maintained. 152-2.11 Finishing and protection of subgrade. Finishing and protection of the subgrade is incidental to this item. Grading and compacting of the subgrade shall be performed so that it will drain readily. All low areas, holes or depressions in the subgrade shall be brought to grade. Scarifying, blading, rolling and other methods shall be performed to provide a thoroughly compacted subgrade shaped to the lines and grades shown on the plans. All ruts or rough places that develop in the completed subgrade shall be graded, re- compacted, and retested. The Contractor shall protect the subgrade from damage and limit hauling over the finished subgrade to only traffic essential for construction purposes. The Contractor shall maintain the completed course in satisfactory condition throughout placement of subsequent layers. No subbase, base, or surface course shall be placed on the subgrade until the subgrade has been accepted by the RPR. 152-2.12 Haul. All hauling will be considered a necessary and incidental part of the work. The Contractor shall include the cost in the contract unit price for the pay of items of work involved. No payment will be made separately or directly for hauling on any part of the work. The Contractor's equipment shall not cause damage to any excavated surface, compacted lift or to the subgrade as a result of hauling operations. Any damage caused as a result of the Contractor's hauling operations shall be repaired at the Contractor's expense. City Project No: 26122 Issue For Bids P-152-5 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 The Contractor shall be responsible for providing, maintaining and removing any haul roads or routes within or outside of the work area, and shall return the affected areas to their former condition, unless otherwise authorized in writing by the Owner. No separate payment will be made for any work or materials associated with providing, maintaining and removing haul roads or routes. 152-2.13 Surface Tolerances.

Asphalt mixture shall not be stored in storage and/or surge bins for a period greater than twelve (12) hours. If the RPR determines there is an excessive heat loss, segregation, or oxidation of the asphalt mixture due to temporary storage, temporary storage shall not be allowed. 401-4.3 Aggregate stockpile management. Aggregate stockpiles shall be constructed in a manner that prevents segregation and intermixing of deleterious materials. Aggregates from different sources shall be stockpiled, weighed and batched separately at the asphalt batch plant. Aggregates that have become segregated or mixed with earth or foreign material shall not be used. A continuous supply of materials shall be provided to the work to ensure continuous placement. 401-4.4 Hauling equipment. Trucks used for hauling asphalt shall have tight, clean, and smooth metal beds. To prevent the asphalt from sticking to the truck beds, the truck beds shall be lightly coated with a minimum amount of paraffin oil, lime solution, or other material approved by the RPR. Petroleum products shall not be used for coating truck beds. Each truck shall have a suitable cover to protect the mixture from adverse weather. When necessary, to ensure that the mixture will be delivered to the site at the specified temperature, truck beds shall be insulated or heated and covers shall be securely fastened. 401-4.4.1 Material transfer vehicle (MTV). Material transfer vehicles used to transfer the material from the hauling equipment to the paver, shall use a self-propelled, material transfer vehicle with a swing conveyor that can deliver material to the paver without making contact with the paver. The MTV shall be able to move back and forth between the hauling equipment and the paver providing material transfer to the paver, while allowing the paver to operate at a constant speed.

The number, type, and weight of rollers shall be sufficient to compact the asphalt to the required density while it is still in a workable condition without crushing of the aggregate, depressions or other damage to the pavement surface. Rollers shall be in good condition, clean, and capable of operating at slow speeds to avoid displacement of the asphalt. All rollers shall be specifically designed and suitable for compacting asphalt concrete and shall be properly used. Rollers that impair the stability of any layer of a pavement structure or underlying soils shall not be used. 401-4.7 Density device. The Contractor shall have on site a density gauge during all paving operations in order to assist in the determination of the optimum rolling pattern, type of roller and frequencies, as well as to monitor the effect of the rolling operations during production paving. The Contractor shall supply a qualified technician during all paving operations to calibrate the gauge and obtain accurate density readings for all new asphalt. These densities shall be supplied to the RPR upon request at any time during construction. No separate payment will be made for supplying the density gauge and technician. 401-4.8 Preparation of asphalt binder. The asphalt binder shall be heated in a manner that will avoid local overheating and provide a continuous supply of the asphalt binder to the mixer at a uniform temperature. The temperature of unmodified asphalt binder delivered to the mixer shall be sufficient to provide a suitable viscosity for adequate coating of the aggregate particles, but shall not exceed 325°F when added to the aggregate. The temperature of modified asphalt binder shall be no more than 350°F when added to the aggregate. 401-4.9 Preparation of mineral aggregate. The aggregate for the asphalt shall be heated and dried. The maximum temperature and rate of heating shall be such that no damage occurs to the aggregates. The temperature of the aggregate and mineral filler shall not exceed 350°F when the asphalt binder is added. Particular care shall be taken that aggregates high in calcium or magnesium content are not damaged by overheating. The temperature shall not be lower than is required to obtain complete coating and uniform distribution on the aggregate particles and to provide a mixture of satisfactory workability. 401-4.10 Preparation of Asphalt mixture. The aggregates and the asphalt binder shall be weighed or metered and mixed in the amount specified by the JMF. The combined materials shall be mixed until the aggregate obtains a uniform coating of asphalt binder and is thoroughly distributed throughout the mixture. Wet mixing time shall be the shortest time that will produce a satisfactory mixture, but not less than 25 seconds for batch plants. The wet mixing time for all plants shall be established by the Contractor, based on the procedure for determining the percentage of coated particles described in ASTM D2489, for each individual plant and for each type of aggregate used. The wet mixing time will be set to achieve 95% of coated particles. For continuous mix plants, the minimum mixing time shall be determined by dividing the weight of its contents at operating level by the weight of the mixture delivered per second by the mixer. The moisture content of all asphalt upon discharge shall not exceed 0.5%. 401-4.11 Application of Prime and Tack Coat. Immediately before placing the asphalt mixture, the underlying course shall be cleaned of all dust and debris. A tack coat shall be applied in accordance with Item P-603 to all vertical and horizontal asphalt and concrete surfaces prior to placement of the first and each subsequent lift of asphalt mixture. 401-4.12 Laydown plan, transporting, placing, and finishing. Prior to the placement of the asphalt, the Contractor shall prepare a laydown plan with the sequence of paving lanes and width to minimize the number of cold joints; the location of any temporary ramps; laydown temperature; and estimated time of completion for each portion of the work (milling, paving, rolling, cooling, etc.). The laydown plan and any modifications shall be approved by the RPR. Deliveries shall be scheduled so that placing and compacting of asphalt is uniform with minimum stopping and starting of the paver. Hauling over freshly placed material shall not be permitted until the material has been compacted, as specified, and allowed to cool to approximately ambient temperature. The Contractor, at their expense, shall be responsible for repair of any damage to the pavement caused by hauling operations. Contractor shall survey each lift of asphalt surface course and certify to RPR that every lot of each lift meets the grade tolerances of paragraph 401-6.2d before the next lift can be placed. City Project No: 26122 Issue For Bids P-401-7 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 Edges of existing asphalt pavement abutting the new work shall be saw cut and the cut off material and laitance removed. Apply a tack coat in accordance with P-603 before new asphalt material is placed against it. The speed of the paver shall be regulated to eliminate pulling and tearing of the asphalt mat. Placement of the asphalt mix shall begin along the centerline of a crowned section or on the high side of areas with a one way slope unless shown otherwise on the laydown plan as accepted by the RPR. The asphalt mix shall be placed in consecutive adjacent lanes having a minimum width of 12.5 feet except where edge lanes require less width to complete the area. Additional screed sections attached to widen the paver to meet the minimum lane width requirements must include additional auger sections to move the asphalt mixture uniformly along the screed extension. The longitudinal joint in one course shall offset the longitudinal joint in the course immediately below by at least one foot; however, the joint in the surface top course shall be at the centerline of crowned pavements. Transverse joints in one course shall be offset by at least 10 feet from transverse joints in the previous course. Transverse joints in adjacent lanes shall be offset a minimum of 10 feet. On areas where irregularities or unavoidable obstacles make the use of mechanical spreading and finishing equipment impractical, the asphalt may be spread and luted by hand tools. The RPR may at any time, reject any batch of asphalt, on the truck or placed in the mat, which is rendered unfit for use due to contamination, segregation, incomplete coating of aggregate, or overheated asphalt mixture. Such rejection may be based on only visual inspection or temperature measurements. In the event of such rejection, the Contractor may take a representative sample of the rejected material in the presence of the RPR, and if it can be demonstrated in the laboratory, in the presence of the RPR, that such material was erroneously rejected, payment will be made for the material at the contract unit price. Areas of segregation in the surface course, as determined by the RPR, shall be removed and replaced at the Contractor's expense. The area shall be removed by saw cutting and milling a minimum of the construction lift thickness as specified in paragraph 401-3.3,Table 2 for the approved mix design. The area to be removed and replaced shall be a minimum width of the paver and a minimum of 10 feet long. 401-4.13 Compaction of asphalt mixture. After placing, the asphalt mixture shall be thoroughly and uniformly compacted by self-propelled rollers. The surface shall be compacted as soon as possible when the asphalt has attained sufficient stability so that the rolling does not cause undue displacement, cracking or shoving. The sequence of rolling operations and the type of rollers used shall be at the discretion of the Contractor. The speed of the roller shall, at all times, be sufficiently slow to avoid displacement of the hot mixture and be effective in compaction. Any surface defects and/or displacement occurring as a result of the roller, or from any other cause, shall be corrected at the Contractor's expense. Sufficient rollers shall be furnished to handle the output of the plant. Rolling shall continue until the surface is of uniform texture, true to grade and cross-section, and the required field density is obtained. To prevent adhesion of the asphalt to the roller, the wheels shall be equipped with a scraper and kept moistened with water as necessary. In areas not accessible to the roller, the mixture shall be thoroughly compacted with approved power tampers. Any asphalt that becomes loose and broken, mixed with dirt, contains check-cracking, or in any way defective shall be removed and replaced with fresh hot mixture and immediately compacted to conform to the surrounding area. This work shall be done at the Contractor's expense. Skin patching shall not be allowed. 401-4.14 Joints.The formation of all joints shall be made to ensure a continuous bond between the courses and obtain the required density. All joints shall have the same texture as other sections of the course and meet the requirements for smoothness and grade. The roller shall not pass over the unprotected end of the freshly laid asphalt except when necessary to form a transverse joint. When necessary to form a transverse joint, it shall be made by means of placing a bulkhead or by tapering the course. The tapered edge shall be cut back to its full depth and width on a City Project No: 26122 Issue For Bids P-401-8 Garver Project No. 2502477 Corpus Christi International Airport AC 150/5370-10H Taxiway Echo Rehabilitation 12/21/2018 straight line to expose a vertical face prior to placing the adjacent lane.

The Contractor shall perform smoothness testing in transverse and longitudinal directions daily to verify that the construction processes are producing pavement with variances less than '/4 inch in 12 feet, identifying areas that may pond water which could lead to hydroplaning of aircraft. If the smoothness criteria is not met,appropriate changes and corrections to the construction process shall be made by the Contractor before construction continues The Contractor may use a 12-foot straightedge, a rolling inclinometer meeting the requirements of ASTM E2133, or rolling external reference device that can simulate a 12-foot straightedge, approved by the RPR. Straight-edge testing shall start with one-half the length of the straightedge at the edge of pavement section being tested and then moved ahead one-half the length of the straightedge for each successive measurement. Testing shall be continuous across all joints. The surface irregularity shall be determined by placing the freestanding (unleveled) straightedge on the pavement surface and allowing it to rest upon the two highest spots covered by its length, and measuring the maximum gap between the straightedge and the pavement surface in the area between the two high points. If the rolling inclinometer or external reference device is used, the data may be evaluated using either the FAA profile program, Pro FAA, or FHWA ProVal, using the 12-foot straightedge simulation function. Smoothness readings shall not be made across grade changes or cross slope transitions. The transition between new and existing pavement shall be evaluated separately for conformance with the plans.

All test methods required for acceptance sampling and testing will be listed on the lab accreditation. b. Lot size. A standard lot will be equal to one day's production divided into approximately equal sublots of between 400 to 600 tons. When only one or two sublots are produced in a day's production, the sublots will be combined with the production lot from the previous or next day. Where more than one plant is simultaneously producing asphalt for the job,the lot sizes will apply separately for each plant. c. Asphalt air voids. Plant-produced asphalt will be tested for air voids on a sublot basis. (1) Sampling. Material from each sublot shall be sampled in accordance with ASTM D3665. Samples shall be taken from material deposited into trucks at the plant or at the job site in accordance with ASTM D979. The sample of asphalt may be put in a covered metal tin and placed in an oven for not less than 30 minutes nor more than 60 minutes to maintain the material at or above the compaction temperature as specified in the JMF. (2)Testing. Air voids will be determined for each sublot in accordance with ASTM D3203 for a set of three compacted specimens prepared in accordance with ASTM D6926. d. In-place asphalt mat and joint density. Each sublot will be tested for in-place mat and joint density as a percentage of the theoretical maximum density (TMD). (1)Sampling. The Contractor will cut minimum 5 inch diameter samples in accordance with ASTM D5361. The Contractor shall furnish all tools, labor, and materials for cleaning, and filling the cored pavement. Laitance produced by the coring operation shall be removed immediately after coring, and core holes shall be filled within one day after sampling in a manner acceptable to the RPR. (2) Bond. Each lift of asphalt shall be bonded to the underlying layer. If cores reveal that the surface is not bonded, additional cores shall be taken as directed by the RPR to determine the extent of unbonded areas. Unbonded areas shall be removed by milling and replaced at no additional cost as directed by the RPR. (3)Thickness. Thickness of each lift of surface course will be evaluated by the RPR for compliance to the requirements shown on the plans after any necessary corrections for grade. Measurements of thickness will be made using the cores extracted for each sublot for density measurement. The maximum allowable deficiency at any point will not be more than 1/4 inch less than the thickness indicated for the lift. Average thickness of lift,or combined lifts,will not be less than the indicated thickness.Where the thickness tolerances are not met, the lot or sublot shall be corrected by the Contractor at his expense by removing the deficient area and replacing with new pavement. The Contractor, at his expense, may take additional cores as approved by the RPR to circumscribe the deficient area. (4) Mat density. One core shall be taken from each sublot. Core locations will be determined by the RPR in accordance with ASTM D3665. Cores for mat density shall not be taken closer than one foot from a transverse or longitudinal joint. The bulk specific gravity of each cored sample will be determined in accordance with ASTM D2726. The percent compaction (density) of each sample will be determined by dividing the bulk specific gravity of each sublot sample by the TMD for that sublot. (5) Joint density. One core centered over the longitudinal joint shall be taken for each sublot that has a longitudinal joint. Core locations will be determined by the RPR in accordance with ASTM D3665. The bulk specific gravity of each core sample will be determined in accordance with ASTM D2726. The percent compaction (density)of each sample will be determined by dividing the bulk specific gravity of each joint density sample by the average TMD for the lot. The TMD used to determine the joint density at joints formed between lots will be the lower of the average TMD values from the adjacent lots.

General. Acceptance will be based on the implementation of the Contractor Quality Control Program (CQCP) and the following characteristics of the asphalt and completed pavements: air voids, mat density, joint density, grade. b. Air Voids and Mat density. Acceptance of each lot of plant produced material for mat density and air voids will be based on the percentage of material within specification limits (PWL). If the PWL of the lot equals or exceeds 90%, the lot will be acceptable. Acceptance and payment will be determined in accordance with paragraph 401-8.1. c. Joint density. Acceptance of each lot of plant produced asphalt for joint density will be based on the PWL. If the PWL of the lot is equal to or exceeds 90%, the lot will be considered acceptable. If the PWL is less than 90%, the Contractor shall evaluate the reason and act accordingly. If the PWL is less than 80%, the Contractor shall cease operations and until the reason for poor compaction has been determined. If the PWL is less than 71%, the pay factor for the lot used to complete the joint will be reduced by five (5) percentage points.

After grading of areas has been completed and before applying fertilizer and limestone, areas to be sodded shall be raked or otherwise cleared of stones larger than 2 inches in any diameter, sticks, stumps, and other debris which might interfere with sodding, growth of grasses, or subsequent maintenance of grass-covered areas. If any damage by erosion or other causes occurs after grading of areas and before beginning the application of fertilizer and ground limestone, the Contractor shall repair such damage.This may include filling gullies, smoothing irregularities, and repairing other incidental damage. 904-3.3 Applying fertilizer and ground limestone. Following ground surface preparation, fertilizer shall be uniformly spread at a rate which will provide not less than the minimum quantity of each fertilizer ingredient, as stated in the special provisions. If use of ground limestone is required, it shall then be spread at a rate that will provide not less than the minimum quantity stated in the special provisions. These materials shall be incorporated into the soil to a depth of not less than 2 inches by discing, raking, or other suitable methods. Any stones larger than 2 inches in any diameter, large clods, roots, and other litter brought to the surface by this operation shall be removed. 904-3.4 Obtaining and delivering sod. After inspection and approval of the source of sod by the RPR, the sod shall be cut with approved sod cutters to such a thickness that after it has been transported and placed on the prepared bed, but before it has been compacted, it shall have a uniform thickness of not less than 2 inches. Sod sections or strips shall be cut in uniform widths, not less than 10 inches, and in lengths of not less than 18 inches, but of such length as may be readily lifted without breaking, tearing, or loss of soil. Where strips are required, the sod must be rolled without damage with the grass folded inside. The Contractor may be required to mow high grass before cutting sod. The sod shall be transplanted within 24 hours from the time it is stripped, unless circumstances beyond the Contractor's control make storing necessary. In such cases,sod shall be stacked, kept moist, and protected from exposure to the air and sun and shall be kept from freezing. Sod shall be cut and moved only when the soil moisture conditions are such that favorable results can be expected. Where the soil is too dry, approval to cut sod may be granted only after it has been watered sufficiently to moisten the soil to the depth the sod is to be cut. 904-3.5 Laying sod. Sodding shall be performed only during the seasons when satisfactory results can be expected. Frozen sod shall not be used and sod shall not be placed upon frozen soil. Sod may be transplanted during periods of drought with the approval of the RPR, provided the sod bed is watered to moisten the soil to a depth of at least 4 inches immediately prior to laying the sod. The sod shall be moist and shall be placed on a moist earth bed. Pitch forks shall not be used to handle sod, and dumping from vehicles shall not be permitted. The sod shall be carefully placed by hand, edge to edge and with staggered joints, in rows at right angles to the slopes, commencing at the base of the area to be sodded and working upward. The sod shall immediately be pressed firmly into contact with the sod bed by tamping or rolling with approved equipment to provide a true and even surface, and ensure knitting without displacement of the sod or deformation of the surfaces of sodded areas. Where the sod may be displaced during sodding operations, the workmen, when replacing it, shall work from ladders or treaded planks to prevent further displacement. Screened soil of good quality shall be used to fill all cracks between sods. The quantity of the fill soil shall not cause smothering of the grass. Where the grades are such that the flow of water will be from paved surfaces across sodded areas, the surface of the soil in the sod after compaction shall be set approximately one inch below the pavement edge. Where the flow will be over the sodded areas and onto the paved surfaces around manholes and inlets, the surface of the soil in the sod after compaction shall be placed flush with pavement edges. On slopes steeper than one (1)vertical to 2-1/2 horizontal and in v-shaped or flat-bottom ditches or gutters, the sod shall be pegged with wooden pegs not less than 12 inches in length and have a cross-sectional area of not less than 3/4 sq inch. The pegs shall be driven flush with the surface of the sod. 904-3.6 Watering. Adequate water and watering equipment must be on hand before sodding begins, and sod shall be kept moist until it has become established and its continued growth assured. In all cases, watering shall be done in a manner that will avoid erosion from the application of excessive quantities and will avoid damage to the finished surface.

Lot 1 Placement.Placement payment adjustments greater than 1.000 for Lot 1 will be in accordance with Section 341.6.2.,"Placement Payment Adjustment Factors"; however,no placement adjustment less than 1.000 will be assessed for any sublot placed in Lot 1 when the in-place air voids are greater than or equal to 2.7%and less than or equal to 9.9%. Remove and replace any sublot with in-place air voids less than 2.7% or greater than 9.9%. 4.9.3.1.2. Incomplete Placement Lots.An incomplete placement lot consists of the area placed as described in Section 341.4.9.2.1.1.,"Incomplete Production Lots,"excluding areas defined in Section 341.4.9.3.1.4., "Miscellaneous Areas."Placement sampling is required if the random sample plan for production resulted in a sample being obtained from an incomplete production sublot. 4.9.3.1.3. Shoulders, Ramps, Etc.Shoulders,ramps, intersections,acceleration lanes,deceleration lanes,and turn lanes are subject to in-place air void determination and payment adjustments unless shown on the plans as not eligible for in-place air void determination. Intersections may be considered miscellaneous areas when determined by the Engineer. 4.9.3.1.4. Miscellaneous Areas.Miscellaneous areas include areas that typically involve significant handwork or discontinuous paving operations,such as temporary detours,driveways, mailbox turnouts,crossovers, gores,spot level-up areas,pavement repair sections less than 300 ft.,and other similar areas.Temporary detours are subject to in-place air void determination when shown on the plans. Miscellaneous areas also include level-ups and thin overlays when the layer thickness shown on the plans is less than the minimum untrimmed core height eligible for testing in accordance with Table 13.The specified layer thickness is based City Project No:26122 Issue For Bids TX-341-25 Garver Project No.2502477 Corpus Christi International Airport TX-341 Taxiway Echo Rehabilitation on the rate of 110 lb.per square yard for each inch of pavement unless another rate is shown on the plans. When"Level Up"is listed as part of the bid item description,a payment adjustment factor of 1.000 will be assigned for all placement sublots as described in Article 341.6.,"Payment."Miscellaneous areas are not eligible for random placement sampling locations. Compact miscellaneous areas in accordance with Section 341.4.8.,"Compaction."Miscellaneous areas are not subject to in-place air void determination, thermal profiles testing,segregation(density profiles),or longitudinal joint density evaluations. 4.9.3.2. Placement Sampling.The Engineer will select random numbers for all placement sublots at the beginning of the project.The Engineer will provide the Contractor with the placement random numbers only immediately after the sublot is completed. Mark the roadway location at the completion of each sublot and record the station number. Determine one random sample location for each placement sublot in accordance with Tex-225-F.Adjust the random sample location by no more than necessary to achieve a 2-ft. clearance if the location is within 2 ft.of a joint or pavement edge. Shoulders, ramps, intersections,acceleration lanes,deceleration lanes,and turn lanes are always eligible for selection as a random sample location; however, if a random sample location falls on one of these areas and the area is shown on the plans as not subject to in-place air void determination,cores will not be taken for the sublot and a 1.000 pay factor will be assigned to that sublot. Provide the equipment and means to obtain and trim roadway cores onsite. Onsite is defined as in close proximity to where the cores are taken. Obtain the cores within 1 working day of the time the placement sublot is completed,unless otherwise approved. Obtain two 6-in.diameter cores side-by-side from within 1 ft. of the random location provided for the placement sublot. Mark the cores for identification, measure and record the untrimmed core height,and provide the information to the Engineer. The Engineer will witness the coring operation and measurement of the core thickness.Visually inspect each core and verify that the current paving layer is bonded to the underlying layer.Take corrective action if an adequate bond does not exist between the current and underlying layer to ensure that an adequate bond will be achieved during subsequent placement operations. Trim the cores immediately after obtaining them from the roadway in accordance with Tex-251-F if the core heights meet the minimum untrimmed value in accordance with Table 13.Trim the cores onsite in the presence of the Engineer. Use a permanent marker or paint pen to record the lot and sublot numbers on each core,as well as the designation as Core A or Core B.The Engineer may require additional information to be marked on the core and may choose to sign or initial the core.The Engineer will take custody of the cores immediately after witnessing the trimming of the cores and will retain custody of the cores until the Department's testing is completed. Before turning the trimmed cores over to the Engineer,the Contractor may wrap the trimmed cores or secure them in a manner that will reduce the risk of possible damage occurring during transport by the Engineer.After testing,the Engineer will return the cores to the Contractor. The Engineer may have the cores transported back to the Department's laboratory at the HMA plant via the Contractor's haul truck or other designated vehicle. In such cases where the cores will be out of the Engineer's possession during transport,the Engineer will use Department-provided security bags and the Protocol for Roadway Core Custody located on the Department's website to provide a secure means and process that protect the integrity of the cores during transport. Decide whether to include the pair of cores in the air void determination for that sublot if the core height before trimming is less than the minimum untrimmed value shown in Table 13.Trim the cores in accordance with Tex-251-F before delivering to the Engineer if electing to have the cores included in the air void determination. If electing to not have the cores included in air void determination, inform the Engineer of the decision,and deliver untrimmed cores to the Engineer.The placement pay factor for the sublot will be 1.000 if cores will not be included in air void determination. Instead of the Contractor trimming the cores onsite immediately after coring,the Engineer and the Contractor may mutually agree to have the trimming operations performed at an alternate location,such as a field laboratory or other similar location. In such cases,the Engineer will take possession of the cores immediately after they are obtained from the roadway and will retain custody of the cores until testing is completed. Either City Project No:26122 Issue For Bids TX-341-26 Garver Project No.2502477 Corpus Christi International Airport TX-341 Taxiway Echo Rehabilitation the Department or Contractor representative may perform trimming of the cores.The Engineer will witness all trimming operations in cases where the Contractor representative performs the trimming operation.

Repair core holes using other methods when approved. 4.9.3.3. Placement Testing.Perform placement tests in accordance with Table 16.After the Engineer returns the cores,the Contractor may test the cores to verify the Engineer's test results for in-place air voids.The allowable differences between the Contractor's and Engineer's test results are shown in Table 11. 4.9.3.3.1. In-Place Air Voids.The Engineer will measure in-place air voids in accordance with Tex-207-F and Tex-227-F. Before drying to a constant weight,cores may be pre-dried using a CoreDry or similar vacuum device to remove excess moisture.The Engineer will average the values obtained for all sublots in the production lot to determine the theoretical maximum specific gravity.The Engineer will use the average air void content for in-place air voids. The Engineer will use the vacuum method to seal the core if required in accordance with Tex-207-F.The Engineer will use the test results from the unsealed core to determine the placement payment adjustment factor if the sealed core yields a higher specific gravity than the unsealed core.After determining the in-place air void content,the Engineer will return the cores and provide test results to the Contractor. 4.9.3.3.2. Informational Shear Bond Strength Testing.The Engineer will select one random sublot within the first four lots of the project for shear bond strength testing.Obtain full-depth cores in accordance with Tex-249-F unless the HMA is being placed directly on concrete pavement. Label the cores with lot and sublot numbers and provide to the Engineer. Inspector must use pertinent Department form to document the CSJ number, producer of the tack coat, mix type,and shot rate.The Engineer will ship the cores to the Materials and Tests Division or District laboratory for shear bond strength testing. Results from these tests will not be used for specification compliance. 4.9.3.3.3. Segregation(Density Profile).Test for segregation using density profiles in accordance with Tex-207-F, Part V.

The bulk specific gravity of each core from each sublot will be divided by the Engineer's average maximum theoretical specific gravity for the lot.The individual core densities for the sublot will be averaged to determine the new payment adjustment factor of the sublot in question. If the new payment adjustment factor is 0.720 or greater,the new payment adjustment factor will apply to that sublot. If the new payment adjustment factor is less than 0.720, no payment will be made for the sublot. Remove and replace the failing sublot,or the Engineer may allow the sublot to be left in place without payment.The Engineer may also accept the sublot in accordance with Section 5.3.1.,"Acceptance of Defective or Unauthorized Work." Replacement material meeting the requirements of this Item will be paid for in accordance with this Section. 6.3. Total Adjusted Pay(TAP)Calculation.TAP will be based on the applicable payment adjustment factors for production and placement for each lot. TAP=(A+B)/2 where: A=Bid price x production lot quantity x average payment adjustment factor for the production lot B=Bid price x placement lot quantity x average payment adjustment factor for the placement lot+(bid price x quantity placed in miscellaneous areas x 1.000) Production lot quantity=Quantity actually placed-quantity left in place without payment Placement lot quantity=Quantity actually placed-quantity left in place without payment-quantity placed in miscellaneous areas City Project No:26122 Issue For Bids TX-341-33 Garver Project No.2502477 Corpus Christi International Airport TX-341 Taxiway Echo Rehabilitation PAGE INTENTIONALLY LEFT BLANK City Project No:26122 Issue For Bids TX-341-34 Garver Project No.2502477 Corpus Christi International Airport TX-462 Taxiway Echo Rehabilitation Item 462 Texas Concrete Box Culverts and Drains !)eanspor t of Transportation 1.

Runway 13-31, Parallel Taxiway B and Associated Taxiways RETL Job Number G121054 Corpus Christi International Airport, Corpus Christi, Texas INTRODUCTION This report presents the results of a soil exploration and a laboratory testing program for the proposed Runway and Taxiway Pavement Rehabilitation project, to include Runway 13-31, Parallel Taxiway B and Associated Taxiways, located at the Corpus Christi International Airport in Corpus Christi, Texas. This study was conducted for Garver, LLC (Garver). Authorization The scope of work for this project was performed in accordance with a Rock Engineering and Testing Laboratory, Inc. (RETL) Proposal No. P111920A, Revision 2, dated December 9, 2020. Our services were approved by Garver, LLC on January 28, 2021 by provision and execution of the Agreement for Subconsultant Professional Services between RETL and Garver, for Garver Project No. 21 A06171. Purpose and Scope The purpose of this exploration was to inventory the existing pavement sections and obtain soil and groundwater data at the site to enable a pavement design for potential repair areas. The scope of the exploration and analysis included the subsurface exploration, field and laboratory testing, engineering evaluation of the subsurface soils, provision of existing pavement constituents and preparation of this report. The scope of work for this project was determined by Garver. The scope of services did not include design of, or design recommendations for, the rehabilitated pavement structures, as we understand that the pavement design will be performed by Garver. In addition, the scope of services did not include an environmental assessment. Any statements in this report, or on the boring logs, regarding odors, colors, unusual or suspicious items or conditions are strictly for the information of the client. General The exploration and analysis of the subsurface conditions reported herein are considered sufficient in detail and scope to provide existing pavement profile information, groundwater data, and empirical or correlative modulus values for the raw subgrade soils and base materials for use by the project designer. The information submitted for the proposed project is based on project details provided by Garver and the pavement and soil information obtained at the boring locations. If the designers require additional soil parameters to complete the design of the proposed repairs or rehabilitation, and this information can be obtained from the soil data and laboratory tests performed within the scope of work included in our proposal for this project, then RETL will provide the additional information requested as a supplement to this report.

Runway 13-31, Parallel Taxiway B and Associated Taxiways RETL Job Number G121054 Corpus Christi International Airport, Corpus Christi, Texas The Geotechnical Engineer states that the findings, specifications or professional advice contained herein have been presented after being prepared in a manner consistent with that level of care and skill ordinarily exercised by reputable members of the Geotechnical Engineer's profession practicing contemporaneously under similar conditions in the locality of the project. RETL operates in general accordance with, "Standard Practice for Minimum Requirements for Agencies Engaged in the Testing and/or Inspection of Soil and Rock as Used in Engineering Design and Construction, (ASTM D3740)." No other representations are expressed or implied, and no warranty or guarantee is included or intended. This study was conducted for Garver and the design team for the specific application to the proposed Runway and Taxiway Pavement Rehabilitation project, to include Runway 13-31, Parallel Taxiway B and Associated Taxiways, located at the Corpus Christi International Airport in Corpus Christi, Texas. SITE DESCRIPTION The site of the planned Runway and Taxiway Pavement Rehabilitation project is located at the Corpus Christi International Airport in Corpus Christi, Texas. There is an existing Runway 13- 31 and Parallel Taxiway B, running in the northwest to southeast direction. The Runway 13- 31 and Taxiway B are each approximately 1.6 miles in length and consist of flexible, asphaltic concrete pavement systems. In addition, multiple smaller taxiways are also present and also consist of flexible, asphaltic concrete pavements. The runway, taxiways and the surrounding areas are relatively flat and level. At the time of our field investigation the condition of the ground surface was firm and did not pose any significant difficulties to the drill crew moving their equipment. A Site Vicinity Map is included in the Appendix of this report. FIELD EXPLORATION Scope The field exploration, to evaluate the thickness and engineering characteristics of the existing pavement materials and pavement bearing materials, included reconnaissance of the project site, performing the test boring operations and obtaining disturbed split spoon soil samples and relatively undisturbed Shelby tube samples. During the sample recovery operations, the soils encountered were classified and recorded on the boring logs in accordance with "Standard Guide for Field Logging of Subsurface Exploration of Soil and Rock, (ASTM D5434)." Nineteen borings were performed for the purpose of providing existing pavement material constituents and pavement subgrade information for the proposed project. The table below provides the boring identification, boring depth and GPS coordinates. Page 2 of 9 February 24, 2021 RUNWAY AND TAXIWAY PAVEMENT REHABILITATION Attn: Mr. Derek Mayo, P.E.

RETL performed the drilling operations. The GPS coordinates were obtained at the boring locations using a Garmin GPS model eTrex and are provided in this report and on the boring logs. Upon completion of the drilling operations and obtaining the groundwater observations, the borings were backfilled with bentonite and the surface was restored using concrete. A Boring Location Plan is provided in the Appendix of this report. Page 3 of 9 February 24, 2021 RUNWAY AND TAXIWAY PAVEMENT REHABILITATION Attn: Mr. Derek Mayo, P.E. Runway 13-31, Parallel Taxiway B and Associated Taxiways RETL Job Number G121054 Corpus Christi International Airport, Corpus Christi, Texas The borings performed for this project were used to determine the pavement material types and thicknesses, as well as the classification and strengths of the subgrade soils. The information provided on the boring logs include boring location, boring depth, pavement materials, soil classification, soil strengths, and laboratory test results. The boring logs are included in the Appendix. Drilling and Sampling Procedures A diamond tipped core barrel was utilized to penetrate and obtain samples of the pavement constituents to a depth where natural in-situ soils were encountered. The test borings were performed using a drilling rig equipped with a rotary head turning solid stem augers to advance the boreholes. Disturbed soil samples were obtained employing split-barrel sampling procedures in general accordance with the procedures for, "Penetration Test and Split-Barrel Sampling of Soils, (ASTM D1586)." Relatively undisturbed soil samples were obtained using thin-wall tube sampling procedures in general accordance with, "Thin Walled Tube Sampling of Soils, (ASTM D1587)." The samples obtained by this procedure were extruded by a hydraulic ram in the field. The samples were visually classified, placed in plastic bags, marked according to boring number, depth and any other pertinent field data, stored in special containers and delivered to the laboratory for testing. Field Observations Penetration Tests — During the sampling procedures, standard penetration tests (SPT) were performed to obtain the standard penetration value of the subgrade soil at selected intervals. The standard penetration value (N) is defined as the number of blows of a 140-pound hammer, falling 30 inches, required to advance the split-barrel sampler 1 foot into the soil. The sampler is lowered to the bottom of the previously cleaned drill hole and advanced by blows from the hammer. The number of blows is recorded for each of three successive 6-inch penetrations. The "N" value is obtained by adding the second and third 6-inch increment number of blows. An automatic hammer was utilized when performing SPT. An automatic hammer is usually taken as having an efficiency of one. The results of standard penetration tests indicate the relative density of cohesionless soils and comparative consistency of cohesive soils, thereby providing a basis for estimating the relative strength and compressibility of the soil profile components. Water Level Observations — Water level observations were obtained during the test boring operations. Water level observations are noted on the boring logs provided in the Appendix. In relatively pervious soils, such as sandy soils, the indicated depths are usually reliable groundwater levels. In relatively impervious soils, such as clay soils, a suitable estimate of the groundwater depth may not be possible, even after several days of observation. Seasonal variations, temperature, land-use, proximity to large water bodies and recent rainfall conditions may influence the depth to the groundwater. The amount of water an open borehole largely depends on the permeability of the soils encountered at the boring locations.

Runway 13-31, Parallel Taxiway B and Associated Taxiways RETL Job Number G121054 Corpus Christi International Airport, Corpus Christi, Texas Ground Surface Elevations — The ground surface elevations at the boring locations were not provided, therefore, depths referred to in this report are from the ground surface at the boring locations during the time of our field investigation. LABORATORY TESTING PROGRAM In addition to the field investigation, a laboratory testing program was conducted to determine additional pertinent engineering characteristics of the subsurface materials. The laboratory testing program included supplementary visual classification (ASTM D2487) and water content tests (ASTM D2216) on the samples. In addition, selected samples were subjected to Atterberg limits tests (ASTM D4318) and percent material finer than the#200 sieve tests (ASTM D1140). The estimated soil shear strengths of cohesive soil samples were obtained using a hand penetrometer. The laboratory testing program was conducted in general accordance with applicable ASTM Specifications. The results of these tests are to be found on the accompanying boring logs provided in the Appendix. SUBSURFACE CONDITIONS General The types of pavement bearing materials encountered in the test borings have been visually classified and are described in detail on the boring logs. The results of the standard penetration tests, hand penetrometer values, water level observations and laboratory tests are presented on the boring logs. Representative samples of the soils were placed in polyethylene bags and are now stored in the laboratory for further analysis, if desired. Unless notified to the contrary, the samples will be disposed of three months after issuance of this report. The stratification of the soil, as shown on the boring logs, represents the soil conditions at the actual boring locations. Variations may occur between or beyond the boring locations. Lines of demarcation represent the approximate boundary between different soil types, but the transition may be gradual, or not clearly defined. It should be noted that, whereas the test borings were drilled and sampled by experienced drillers, it is sometimes difficult to record changes in stratification within narrow limits. In the absence of foreign substances, it is also difficult to distinguish between discolored soils and clean soil fill.

Phenolphthalein is a chemical compound that can be used as an indicator of the presence of lime, as it turns colorless in acidic solutions and pink in basic solutions. Based upon the phenolphthalein testing on the clayey subgrade at each boring location, it appears that lime is present in the subgrade soils as indicated in the following table.

Most notable is the presence of a clayey sand subgrade at Boring B-1. Detailed descriptions of the soils encountered at the boring locations are provided on the boring logs included in the Appendix. Groundwater Observations Groundwater was encountered in Boring B-13 at a depth of approximately 13 feet during the drilling operations and was measured within the open borehole at a depth of approximately 13.5 feet upon completion of drilling. Groundwater was not encountered in any of the remaining soil borings or observed within the open boreholes upon completion of drilling. It should be noted that the water level in open boreholes may require several hours to several days to stabilize depending on the permeability of the soils and that groundwater levels at this site may be subject to seasonal conditions, recent rainfall, drought or temperature effects. PAVEMENT CONSIDERATIONS Potential Vertical Rise (PVR) The laboratory test results indicate that the subsoils in the active zone at this site are high to very high in plasticity. The calculated total potential vertical rise (PVR) at this site, considering undeveloped land or unpaved areas, is estimated to be approximately 4 to 41/4 inches. In consideration of the existing pavement structures, the PVR in the pavement areas is estimated to be approximately 2'/2 to 2% inches. These PVR values represent the vertical rise that can be experienced by dry subsoils if they are subjected to conditions that allow them to become saturated, such as poor drainage. The actual movement of the subsoils is dependent upon their change in moisture content. The PVR was calculated using the Texas Department of Transportation Method TEX-124E and took into account the depth of the active zone, estimated to extend to a depth of approximately 15 feet at this site, and the Atterberg limits test results of the soils encountered within the active zone. Page 8 of 9 February 24, 2021 RUNWAY AND TAXIWAY PAVEMENT REHABILITATION Attn: Mr. Derek Mayo, P.E. Runway 13-31, Parallel Taxiway B and Associated Taxiways RETL Job Number G121054 Corpus Christi International Airport, Corpus Christi, Texas Reduction of PVR is typically not performed beneath pavements servicing typical automobile and service vehicle types of traffic and therefore specific PVR reduction recommendations are not provided in this report. However, if PVR reduction is required in the design or desired by the pavement designers, RETL should be contacted for specific PVR reduction recommendations. Subgrade Soil and Base Material Parameters The California Bearing Ratio (CBR) is a penetration test that is commonly used in pavement design and represents a ratio to that of crushed stone. Specific field or laboratory CBR testing has not been performed for this analysis. Based upon local experience and correlative data, the estimated CBR value for the natural fat clay subgrade soils encountered with the upper 5 to 10 feet at this site is 2. The Resilient Modulus (Mr), a measure of material stiffness, is often used in pavement response computation models to characterize unbound pavement materials and is common in mechanistic-empirical pavement design methods. It is defined as a ratio of applied axle deviator stress and recoverable axial strain. Specific laboratory testing has not been performed for this analysis. Based on our experience and correlative data and considering the variability in the existing base material types and thicknesses identified at the boring locations, the estimated Mr value for the governing existing base material is 10,000 psi. GENERAL COMMENTS If significant changes are made in the character or location of the proposed project, a consultation should be arranged to review any changes with respect to the prevailing soil conditions. At that time, it may be necessary to submit supplementary recommendations. It is recommended that the services of RETL be engaged to test and evaluate the soils in the pavement excavations prior to placing pavement constituents in order to verify that the existing pavement materials and bearing soils are consistent with those encountered in the borings. RETL cannot accept any responsibility for any conditions that deviate from those described in this report, nor for the performance of the rehabilitated pavements if not engaged to also provide construction observation and testing for this project. If it is required for RETL to accept any liability, then RETL must agree with the plans and perform such observation during construction as we recommend. All sheeting, shoring and bracing of trenches, pits and excavations should be made the responsibility of the contractor and should comply with all current and applicable local, state and federal safety codes, regulations and practices, including the Occupational Safety and Health Administration.
