Engineer II RE: Proposal for Geotechnical Services Proposed Slough Road Reconstruction and New CR 7B Extension (18042A) 2018/2019 MSA Geotechnical and Materials Testing (17099A) Corpus Christi, Texas Proposal #: 247954 Dear Ms. Alaniz: Intertek-Professional Service Industries, Inc. (PSI) is pleased to submit this proposal to conduct a geotechnical exploration at the above referenced property. PSI thanks you for the opportunity to propose these geotechnical services and looks forward to being part of the design team. This work will include reconstruction of a portion of Slough Road and and a new CR 7B Extension. A review of project information, along with a proposed scope of services, schedule and fee information is provided below. PROJECT UNDERSTANDING Project information was provided by Ms. Marisa Alaniz. E.I.T. with the City of Corpus Christi Engineering Services Department. PSI understands approximately 4,000 LF of existing Slough Road will be reconstructed including the widening of the road and a center turn lane. Also included in the project will be a new 1,900 LF County Road 7B extension to Slough Road. The geotechnical exploration will be performed for residential street design per City of Corpus Christi requirements. A Site Description is provided in Table 1 and a Project Description is provided in Table 2 below based on currently available information: Table 1 —Site Description Site Location Slough Road—Rodd Field Rd.to Amethyst Dr. County Road 76 Extension to Slough Road Slough Road is an existing distressed asphalt roadway and Existing Site Ground Cover the CR 7B Extension site is currently primarily a natural ground pathway A Pond exists adjacent to the northern portion of the North Existing Site Features Extension on the west side. Otherwise the project area is surrounded primarily by residential developments Existing Grade/Elevation Changes Relatively flat Ground Surface Soil Support Capability Firm Enough for Field Equipment Intertek—Professional Service Industries,Inc.•810 S Padre Island Drive,Corpus Christi,TX 78416•Phone(361)854-4801•Fax(361)854-6049 Exhibit A Page 1 of 7 • Proposed Slough Road Reconstruction and CR 7B Extension June 18,2018 Corpus Christi, Texas PSI Proposal No. 247954 Page 2 of 7 Table 2-General Project Description Slough Road Approximately 4,000 LF to be Reconstruction and Designed per Residential Collector Classification CR 7B Extension Approximately 1,900 LF of New Roadway Designed per Residential Classification Should the above information or assumptions be inconsistent with planned construction, the Client should contact the PSI office and allow necessary modifications be made to the proposal. SCOPE OF SERVICES The geotechnical engineering scope of services will include the following items. • Field exploration consisting of drilling and sampling of the subsurface materials and observing groundwater levels at the site. • Laboratory testing of the subsurface materials. • Performing engineering analyses and providing geotechnical recommendations in a geotechnical report. Field Exploration A total of thirteen (13)soil borings are proposed for this project at the approximate locations shown on the attached Boring Location Plan. The table below summarizes the planned exploratory boring program. Table 3-Summary of Borings Design Element Number of Boring Depth(s) Drilling Footage Borings (feet) (feet) Slough Road Pavement 8 5 40 New CR 7B Extension Pavement 5 5 25 TOTAL 13 --- 65 The borings locations will be identified in the field using available natural landmarks or GPS coordinates.Surveying of the boring locations to obtain surface coordinates and elevations is beyond the scope of work and should be surveyed by others prior to construction. References to elevations of various subsurface strata will be based on depths below existing grade at the time of drilling. • During the field activities, the subsurface conditions were observed, logged, and visually classified field notes were maintained to summarize soil types and descriptions, water levels, changes in subsurface conditions, and drilling conditions • Final depths of the borings may be extended or reduced depending on the subsurface materials identified during field activities. • PSI will contact Texas One Call/Dig Tess, etc. or other public utility clearance companies prior to the start of drilling activities. It is our experience that these companies do not mark the locations of privately owned utilities. This proposal is based on private utility lines and other subsurface appurtenances are located in the field by others prior to field activities. me ASI Exhibit A �� Page 2 of 7 • Proposed Slough Road Reconstruction and CR 78 Extension June 18,2018 Corpus Christi, Texas PSI Proposal No. 247954 Page 3 of 7 • Some damage to the ground surface may result from the drilling operations near the work areas and along ingress/egress pathways. The field crew will attempt to limit such damage, but no restoration other than backfilling the borings is included in this proposal. Excess auger cuttings and drilling spoils would be spread of on the site. • PSI will exercise reasonable caution to avoid damages to underground utilities by contacting local utility companies prior to the field activities. However, private utility locations are often unknown by public utility companies and by the utility owners. Therefore, PSI will not be responsible for damage to the site or any buried utilities that are not made known to us. • PSI will provide traffic control during drilling and sampling operations.

Portions of any samples that are not altered or consumed by laboratory testing will be retained for 60 days after the issuance of the final geotechnical report and will then be discarded. Engineering Analyses and Report The results of the field exploration and laboratory testing will be used in the engineering analysis and in the formulation of the recommendations. The results of the subsurface exploration, including the recommendations and the data on which they are based, will be presented in a written geotechnical report. The geotechnical report will include the following items: • A review of surface topographical features, geologic features, and site conditions; • Boring location plan and boring logs with laboratory test results of subsurface materials encountered including groundwater levels; • Discussion of potential soil movements relating to shrinking and swelling soils • Site preparation requirements and pavement section thickness recommendations for mim �ASI Exhibit A 1"t Page 3 of 7 • • Proposed Slough Road Reconstruction and CR 7B Extension June 18,2018 Corpus Christi, Texas PSI Proposal No. 247954 Page 4 of 7 flexible pavement systems considering the reconstruction of Slough Road and a new pavement section for the North Extension • Pavement construction considerations based on provided design traffic information A pdf version of the geotechnical report,will be prepared and submitted by email to the Client and design team. If requested by the Client, additional hard copies can be provided.The geotechnical report will be reviewed, signed, and sealed by a registered Professional Engineer. SCHEDULE Based on the site being accessible to the truck rig, drilling can commence within approximately one week after receipt of authorization to proceed, weather permitting. Preliminary verbal recommendations could be made available after laboratory testing is completed. A final report can be provided within four(4)weeks of authorization. Delays sometime occur due to adverse weather, utility clearance requirements, site clearing requirements for drill rig access, obtaining drilling permits, obtaining Right of Entries and other factors outside of PSI's control. In this event, PSI will communicate the nature of the delay and provide a revised schedule at the earliest possible date. FEE PSI proposes the fee for performance of the outlined scope of services be charged on a unit rate basis based upon PSI's 2018/2019 Master Service Agreement for Geotechnical and Materials Testing(17099A)shown on the attached Estimated Fee Breakdown.Based on the scope of services outlined above, the estimated fee will be$10,589.00. The estimate fee is based on the boring locations being accessible to truck-mounted drilling equipment and the Client providing permission for PSI to enter and access the site. Not included in the proposed fee are costs associated with locating private underground utilities, reviewing foundation drawings, preparing construction specifications, attending special conferences, providing environmental consulting, and any other work requested after submittal of the report. PSI will exercise reasonable caution to avoid damages to underground utilities by contacting local utility companies prior to the field activities. However, utility locations on the owners'side of the meter are often unknown by utility companies and by the utility owners. Therefore, PSI will not be responsible for damage to any buried utilities that are not made known to us. Authorization PSI will proceed with the work upon issuance by the City of Corpus Christi of the Task Order to proceed with this project. Intertek Exhibit A M�f.
