ARTICLE 11—AMENDING THE CONTRACT DOCUMENTS;CHANGES IN THE WORK
11.01 Amending and Supplementing the Contract Documents
A. The Contract Documents may be modified by a Contract Amendment, Change Order, Work
Change Directive, or Field Order.
1. Contract Amendment: Owner and Contractor may modify the terms and conditions of
the Contract Documents without the recommendation of the Designer using a Contract
Amendment. A Contract Amendment may be used for:
a. Changes that do not involve:
1) The performance or acceptability of the Work;
2) The design as described in the Drawings, Specifications, or otherwise; or
3) Other engineering, architectural or technical matters.
b. Authorizing new phases of the Work and establishing the Contract Price, Contract
Times, or terms and conditions of the Contract for the new phase of Work when
using phased construction or purchasing Goods and Special Services to be
incorporated into the Project.
General Conditions 00 72 00-50
Corpus Christi Standards Rev 6/2021
2. Change Order: All changes to the Contract Documents that include a change in the
Contract Price or the Contract Times for previously authorized Work, or changes to the
Work requiring Designer's approval must be made by a Change Order. A Change Order
may also be used to establish modifications of the Contract Documents that do not
affect the Contract Price or Contract Times.
3. Work Change Directive: A Work Change Directive does not change the Contract Price
or the Contract Times, but is evidence that the parties expect that the modifications
ordered or documented by a Work Change Directive will be incorporated in a
subsequently issued Change Order following negotiations on the Contract Price and
Contract Times. If negotiations under the terms of the Contract Documents governing
adjustments, expressly including Paragraphs 11.04 and 11.05 are unsuccessful,
Contractor must submit a Change Proposal seeking an adjustment of the Contract Price
or the Contract Times no later than 30 days after the completion of the Work set out in
the Work Change Directive.
4. Field Order: Designer may require minor changes in the Work that do not change the
Contract Price or Contract Times using a Field Order. OAR may issue a Field Order for
non-technical, administrative issues. Submit a Change Proposal if Contractor believes
that a Field Order justifies an adjustment in the Contract Price or Contract Times before
proceeding with the Work described in the Field Order.
B. Perform added or revised Work under the applicable provisions of the Contract Documents
for the same or similar Work unless different Drawings, Specifications or directions are
provided in the Modification.
11.02 Owner-Authorized Changes in the Work
A. Owner may order additions, deletions,or revisions in the Work at any time as recommended
by the Designer to the extent the change:
1. Involves the design as described in the Contract Documents;
2. Involves acceptance of the Work; or
3. Involves other engineering, architectural or technical matters.
B. These changes may be authorized by a Modification. Proceed with the Work involved or, in
the case of a deletion in the Work, immediately cease construction activities with respect to
the deleted Work upon receipt of the Modification. Nothing in this paragraph obligates the
Contractor to undertake Work that Contractor reasonably concludes cannot be performed
in a manner consistent with Contractor's safety obligations under the Contract Documents
or Laws and Regulations.
11.03 Unauthorized Changes in the Work
A. Contractor is not entitled to an increase in the Contract Price or an extension of the Contract
Times with respect to Work performed that is not required by the Contract Documents,
except in the case of an emergency as provided in Paragraph 7.12, or in the case of
uncovering Work as provided in Paragraph 16.05.
General Conditions 00 72 00-51
Corpus Christi Standards Rev 6/2021
B. Contractor is responsible for costs and time delays associated with variations from the
requirements of the Contract Documents unless the variations are specifically approved by
Change Order.
11.04 Change of Contract Price
A. The Contract Price for authorized Work can only be changed by a Change Order. Any Change
Proposal for an adjustment in the Contract Price must comply with the provisions of
Paragraph 11.06. Any Claim for an adjustment of Contract Price must comply with the
provisions of Article 13.
B. An adjustment in the Contract Price is to be determined as follows:
1. By applying unit prices to the quantities of the items involved, subject to the provisions
of Paragraph 15.03, where the Work involved is covered by unit prices in the Contract
Documents;
2. By a mutually agreed lump sum where the Work involved is not covered by unit prices
in the Contract Documents; or
3. Payment on the basis of the Cost of the Work determined as provided in Paragraph
15.01 plus a Contractor's fee for overhead and profit determined as provided in
Paragraph 15.05 when the Work involved is not covered by unit prices in the Contract
Documents and the parties do not reach a mutual agreement to a lump sum.
C. The original Contract Price may not be increased by more than 25 percent or the limit set out
in Texas Local Government Code 252.048 or its successor statute, whichever is greater.
Owner may decrease the Work by up to 25 percent of the Contract Price.
11.05 Change of Contract Times
A. The Contract Times for authorized Work can only be changed by Change Order. Any Change
Proposal for an adjustment in the Contract Times must comply with the provisions of
Paragraph 11.06. Any Claim for an adjustment in the Contract Times must comply with the
provisions of Article 13.

Contractor, including undisputed sums or amount of time for Work actually performed
in accordance with a Work Change Directive;
2. Changes in Contract Price resulting from Owner set-offs unless the set-off has been
successfully challenged by Contractor;
3. Changes in the Work which are:
a. Ordered by Owner pursuant to Paragraph 11.02.A,
b. Required because Defective Work was accepted under Paragraph 16.04 or Owner's
correction of Defective Work under Paragraph 16.07, or
c. Agreed to by the Owner and Contractor; and
4. Changes in the Contract Price or Contract Times, or other changes under Paragraph
11.06 or Article 13.
B. Acceptance of a Change Order by Contractor constitutes a full accord and satisfaction for any
and all claims and costs of any kind, whether direct or indirect, including but not limited to
impact, delay or acceleration damages arising from the subject matter of the Change Order.
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. Contractor may file a Claim for payment and/or time, pursuant to
Article 13.

Note: Executive Order(EO) 13706, Establishing Paid Sick Leave
for Federal Contractors applies to all contracts subject to the
Davis-Bacon Act for which the contract is awarded (and any
solicitation was issued) on or after January 1, 2017. 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
Supplementary Conditions 00 73 00-6
23061 16-inch Water Main Extension—SH 286 to Alameda St Rev 3/2023
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
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
Supplementary Conditions 00 73 00-7

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
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
Supplementary Conditions 00 73 00-8
23061 16-inch Water Main Extension—SH 286 to Alameda St Rev 3/2023
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.
Supplementary Conditions 00 73 00-9
23061 16-inch Water Main Extension—SH 286 to Alameda St Rev 3/2023
A UAVG rate will be updated once a year, usually in January,to
reflect a weighted average of the current rates in the
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
Supplementary Conditions 00 73 00- 10
23061 16-inch Water Main Extension—SH 286 to Alameda St Rev 3/2023
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
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.

Temporary Controls 01 57 00-4
23061 16-inch Water Main Extension—SH 286 to Alameda St Rev 8/2019
C. An alternative to sheet flow is to pump storm water to an area where ponding occurs
naturally without leaving the designated work area or by a manmade berm(s) prior to
entering the storm water system. Sheet flow and ponding is to allow solids screening and/or
settling prior to entering a storm water conduit or inlet.
D. Storm water or groundwater shall not be discharged to private property without permission.
It is the intent that Contractor discharges groundwater primarily into the existing storm
water system, provided that the quality of groundwater is equal to or better than the
receiving stream,the Corpus Christi Bay.
E. Testing of groundwater quality is to be performed by the Contractor, at the Contractor's
expense, prior to commencing discharge and shall be retested by the Contractor, at the
Contractor's expense, a minimum of once a week. 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.
Groundwater flow can be estimated by boring a hole or excavating a short trench then record
water level shortly after completion, allow to sit overnight, record water level again, pump
hole or trench dry to a holding tank or vacuum truck then record how long it takes to fill to
original level and overnight level.
1.12 DISPOSAL OF CONTAMINATED GROUNDWATER
A. An allowance will be included in the Bid for the unanticipated disposal of contaminated
groundwater. This allowance may not be needed but is provided in case contaminated
groundwater is encountered during the course of the Project and does not meet the water
quality requirements for discharge into the storm water or wastewater systems. This
allowance includes all materials, tools, equipment, labor, transportation, hauling,
coordination, and proper disposal of the contaminated water at an approved landfill, deep
water injection well, or other site as agreed to by the Designer. Suggested disposal facilities
would be [US Ecology (USET) in Robstown, Texas or Texas Molecular in Corpus Christi,
Texas].
B. The payment for this Work will be based on the Contractor's actual costs and will be
negotiated. Payment will not include costs associated with routine dewatering, which is
considered subsidiary to the appropriate bid items as described in Paragraph 1.11.

EXCAVATION AND BACKFILL FOR UTILITIES
1. DESCRIPTION
This specification shall govern all work for excavation and backfill for utilities required to complete
the project.
2. CONSTRUCTION
(1) Unless otherwise specified on the drawings or permitted by the Engineer, all pipe and
conduit shall be constructed in open cut trenches with vertical sides. Trenches shall be
sheathed and braced as necessary throughout the construction period. Sheathing and bracing
shall be the responsibility of the Contractor (refer to Section 022022 "Trench Safety for
Excavations" of the City Standard Specifications).
Trenches shall have a maximum width of one foot beyond the horizontal projection of the
outside surfaces of the pipe and parallel thereto on each side unless otherwise specified.
The Contractor shall not have more than 200 feet of open trench left behind the trenching
operation and no more than 500 feet of ditch behind the ditching machine that is not
compacted as required by the plans and specifications. No trench or excavation shall remain
open after working hours.
For all utility conduit and sewer pipe to be constructed in fill above natural ground, the
embankment shall first be constructed to an elevation not less than one foot above the top of
the pipe or conduit, after which excavation for the pipe or conduit shall be made.
If quicksand, muck, or similar unstable material is encountered during the excavation, the
following procedure shall be used unless other methods are called for on the drawings. If the
unstable condition is a result of ground water,the Contractor,prior to additional excavation,
shall control it. After stable conditions have been achieved,unstable soil shall be removed or
stabilized to a depth of 2 feet below the bottom of pipe for pipes 2 feet or more in height;and
to a depth equal to the height of pipe, 6 inches minimum,for pipes less then 2 feet in height.
Such excavation shall be carried at least one foot beyond the horizontal limits of the structure
on all sides. All unstable soil so removed shall be replaced with suitable stable material,
placed in uniform layers of suitable depth as directed by the Engineer,and each layer shall be
wetted, if necessary, and compacted by mechanical tamping as required to provide a stable
condition. For unstable trench conditions requiring outside forms, seals, sheathing and
bracing, any additional excavation and backfill required shall be done at the Contractor's
expense.
(2) Shaping of Trench Bottom. The trench bottom shall be undercut a minimum depth sufficient
to accommodate the class of bedding indicated on the plans and specifications.
022020
Page 1 of 4
Rev.3-25-2015
(3) Dewatering Trench. Pipe or conduit shall not be constructed or laid in a trench in the
presence of water. All water shall be removed from the trench sufficiently prior to the pipe
or conduit planing operation to insure a relatively dry (no standing water), firm bed. The
trench shall be maintained in such dewatered condition until the trench has been backfilled to
a height at lease one foot above the top of pipe. Removal of water may be accomplished by
bailing,pumping, or by installation of well-points,as conditions warrant. Removal of well-
points shall be at rate of 1/3 per 24 hours (every third well-point). The Contractor shall
prevent groundwater from trench or excavation dewatering operations from discharging
directly into the storm water system. Groundwater from dewatering operations shall be
sampled and tested, if applicable, and disposed of, in accordance with City Standard
Specification Section 022021 "Control of Ground Water".
(4) Excavation in Streets. Excavation in streets,together with the maintenance of traffic where
specified, and the restoration of the pavement riding surface, shall be in accordance with
drawing detail or as required by other applicable specifications.
(5) Removing Abandoned Structures. When abandoned masonry structures or foundations are
encountered in the excavation, such obstructions shall be removed for the full width of the
trench and to a depth one foot below the bottom of the trench. When abandoned inlets or
manholes are encountered and no plan provision is made for adjustment or connection to the
new utility,such manholes and inlets shall be removed completely to a depth one foot below
the bottom of the trench. In each instance,the bottom to the trench shall be restored to grade
by backfilling and compacting by the methods provided hereinafter for backfill. Where the
trench cuts through utility lines which are known to be abandoned, these lines shall be cut
flush with the sides of the trench and blocked with a concrete plug in a manner satisfactory to
the Engineer.
(6) Protection of Utilities. The Contractor shall conduct his work such that a reasonable
minimum of disturbance to existing utilities will result. Particular care shall be exercised to
avoid the cutting or breakage of water and gas lines. Such lines,if broken, shall be restored
promptly by the Contractor. When active wastewater lines are cut in the trenching
operations, temporary flumes shall be provided across the trench while open, and the lines
shall be restored when the backfilling has progressed to the original bedding line of the sewer
so cut.
The Contractor shall inform utility owners sufficiently in advance of the Contractor's
operations to enable such utility owners to reroute, provide temporary detours, or to make
other adjustments to utility lines in order that the Contractor may proceed with his work with
a minimum of delay. The Contractor shall not hold the City liable for any expense due to
delay or additional work because of utility adjustments or conflicts.
(7) Excess Excavated Material. All materials from excavation not required for backfilling the
trench shall be removed by the Contractor from the job site promptly following the
completion of work involved.

or conduit not located under pavements (including waterlines, gravity wastewater lines,
wastewater force mains and reinforced concrete storm water pipe) shall be imported select
material or clean, excess material from the excavation meeting the following requirements:
Free of hard lumps, rock fragments, or other debris,
No clay lumps greater than 2" diameter
Moisture Content: +/-3%
Backfill material shall be placed in layers not more than ten (10) inches in depth (loose
measurement),wetted if required to obtain proper compaction,and thoroughly compacted by
use of mechanical tampers to the natural bank density but not less than 95%Standard Proctor
density,unless otherwise indicated. Flooding of backfill is not allowed. Jetting of backfill
may only be allowed in sandy soils and in soils otherwise approved by the Engineer.
Regardless of backfill method, no lift shall exceed 10 inches and density shall not be less
than 95% Standard Proctor density. A period of not less than twenty-four (24)hours shall
elapse between the time of jetting and the placing of the top four (4) feet of backfill. If
jetting is used, the top four (4) feet of backfill shall be placed in layers not more than 10
inches in depth (loose measurement), wetted if required to obtain proper compaction, and
thoroughly compacted by use of mechanical tampers to the natural bank density but not less
than 95% Standard Proctor density(ASTM D698).
PAVED AREAS: At utility line crossings under pavements (including waterlines, gravity
wastewater lines, wastewater force mains, and reinforced concrete stone water pipe), and
where otherwise indicated on the drawings, trenches shall be backfilled as shown below:
From top of initial backfill (typically twelve (12) inches above top of the pipe)to three

2. CONSTRUCTION METHODS
(A) Stripping and Excavation
Strip the top 6 inches in all areas to underlay compacted fill, curbs, base or pavement, by removing
all humus, vegetation and other unsuitable materials. Unless otherwise noted, remove existing
trees, shrubs, fences, curb, gutter, sidewalk, drives, paving, pipe and structures and other items
within the graded area which interfere with new construction of finished grading.
All suitable excavated materials shall be utilized, insofar as practicable, in constructing the required
roadway sections or in uniformly widening embankments, flattening slopes, etc., as directed by the
Engineer, provided that the material meets the requirements for roadway embankment as specified
in Article 3 below. Unwanted or unsuitable roadway excavation and roadway excavation in excess
of that needed for construction shall become the property of the Contractor to be disposed of by him
outside the limits of the right-of-way at a location suitable to the Engineer. "Unsuitable" material
encountered below subgrade elevation in roadway cuts, when declared unwanted by the Engineer,
shall be replaced as directed by the Engineer with suitable material from the roadway excavation or
with other suitable material.
Maintain moisture and density until covered and protected by the subbase or base course. Remove
soft or wet areas found at any time, replace with suitable material, and recompact (especially utility
trenches).
(B) Subgrade Preparation
That area shown on the drawings for street construction shall be cut to grade, scarified to a depth
not less than 6 inches, or as otherwise indicated on the drawings, and compacted to 95% Standard
Proctor density (ASTM D698) to within 0 to +3% of optimum moisture. The section may be
accepted if no more than I in 5 of the most recent moisture or density tests is beyond+I% deviation
from the required moisture or density requirement. Irregularities exceeding %2 inch in 16 feet shall
be corrected. Soft areas found at anytime shall be removed, replaced with suitable material and
compacted (especially at utility trenches). The correct moisture density relationship shall be
maintained until the subgrade is protected. Excessive loss of moisture shall be prevented by
sprinkling, sealing, or covering with a subsequent layer. Should the subgrade, due to any reason or
cause, lose the required stability, density, or moisture before it is protected by placement of the next
layer, it shall be re-compacted and refinished and retested at the expense of the Contractor until
acceptable to the City.

BITUMINOUS ADHESIVE FOR PAVEMENT MARKERS
EFFECTIVE DATE:JANUARY 2008
6130.1. Description. This Specification establishes the requirements for bituminous type hot-
melt adhesive used for the placement of pavement markers. Two types are addressed: standard
bituminous marker adhesive consisting of an asphalt base with homogeneously mixed mineral
tiller; and flexible bituminous marker adhesive consisting of a highly polymer modified asphalt.
Either adhesive must be suitable for bonding ceramic and plastic markers to hydraulic cement
concrete, asphaltic concrete, and chip-sealed road surfaces and be applicable when road surface
and marker temperatures are in the approximate range of 4-71°C (40-160°F).
The composition of the adhesive must be such that its properties will not deteriorate when heated
to and applied at temperatures up to 218°C (425°F)using either air or oil-jacketed melters.
6130.2. Units of Measurements. The values given in parentheses (if provided) are not standard
and may not be exact mathematical conversions. Use each system of units separately. Combining
values from the two systems may result in nonconformance with the standard.
6130.3. Material Requirements.
A. Adhesive Properties. The adhesive must be smooth and homogeneous, containing no
visible particles, and must comply with the requirements in Table 1.

6130.4. Test Methods.
A. Heat Stability Flow. To determine the heat stability flow, place 1000 g of adhesive in a
loosely-covered quart can,heat to 218°C (425°F) and maintain at this temperature 4 hours
before performing the flow test.
B. Extraction and Abson Recovery. Use this procedure to separate and recover the base
asphalt from the adhesive. Heat the adhesive just to the point where it will easily flow.
Transfer between 125 and 150 g into a 1000-mL (I-qt.) Erlenmeyer flask containing
400 mL (13.5 fl. oz.) of trichloroethylene with a temperature of 52-66°C (125-150°F).
Stir this mixture thoroughly to dissolve the asphalt. Decant the solvent-asphalt mixture.
Recover the base asphalt from solvent according to Tex-211-F, but begin with the
centrifuge step; the primary distillation is not necessary. Repeat the above extraction-
recovery method as necessary to obtain the desired quantity of asphalt.
C. Filler Separation Technique. Use this procedure to separate the filler material from the
asphalt and determine the filler content of the adhesive. Weigh 10.00 10.01 g of solid
adhesive,broken into small pieces, into a centrifuge flask with approximately 100 mL
(3.5 fl. oz.)volume such as that specified in ASTM D 1796. Add 50 mL (1.7 fl. oz.) of
trichloroethylene to the adhesive. Swirl or stir the mixture with a fine rod, taking care not
TEXASDEPARTMENT OF TRANSPORTATION 2-3 LAST REVIEWED:SEPTEMBER 2014
DEPARTMENTAL MATERIALS SPECIFICATION BITUMINOUS ADHESIVE FOR PAVEMENT MARKERS
to lose any solids. Place the sample flask in a balanced centrifuge and spin using a
minimum relative centrifugal force of 150 (as determined in ASTM D 1796, Section 6.)
Remove the sample flask and decant the solvent, taking care not to lose any solids.
Repeatedly add more solvent, centrifuge, and decant until the solvent becomes clear and
the filler appears free of asphalt. Dry the recovered filler at 71 ± YC (160± 5°F) to
remove solvent. Weigh the dried filler. Filter the decanted solvent through a filter paper
with a 20-25 µm retention factor to verify there is no loss of filler. Calculate the filler
content as a percentage of the original sample weight.
D. Filler Fineness. Use this procedure to determine the filler fineness. Use the same
apparatus as described in ASTM C 430, except also use 75µm (No. 200) and 150 µm
(No. 100) sieves. Prepare a water solution containing 1 wt. percent of a nonionic, water-
soluble surfactant, such as Triton X-100,beforehand. Thoroughly wet the 1 g dry sample
in the surfactant solution and allow it to soak for 30 min. Transfer the filler completely
into the 45 µm (No. 325) sieve cup. Wash the sample with the water spray, as described in
ASTM C 430, Section 5, for 2 min., adding surfactant solution as needed to disperse any
clumped particles. Dry and weigh the sample and perform calculations as directed in
ASTM C 430. Repeat the procedure using the other two sieve sizes.
6130.5. Acceptance. Bituminous adhesives are pre-qualified in accordance with Tex-538-C.
Consult "Bituminous Marker Adhesive" for a list of materials currently pre-qualified under this
procedure.
6130.6. Packaging and Labeling. Package the adhesive in self-releasing cardboard containers
with essentially flat and parallel top and bottom surfaces such that the packages will stack
properly. Each package must have a net weight of either 23 or 27 kg (50 or 60 lb.) and must
weigh within 1 kg (2 lb.) of the stated quantity.
Self-releasing cardboard dividers, which will separate each package into sections weighing no
more than 7 kg (15 lb.) each, must be part of the packaging.
Each package must display:
• the manufacturer's name,
• net weight,
• lot or batch number, and
• a product name that clearly identifies the material as either standard or flexible bituminous
marker adhesive.

applicable City Standard Details for Water.
(4) POLYETHYLENE WRAPPING
All ductile iron pipe, valves and fittings, except pipe or valves which are laid in encasement
pipe or in concrete valve boxes, shall be wrapped in polyethylene. The polyethylene
material shall have a thickness of 8 mils and may be either clear or black. The wrapping
shall be lapped in such manner that all surfaces of pipe, valves and fittings, including joints,
shall have a double thickness of polyethylene. If a single longitudinal lap is made using a
double thickness of polyethylene, it shall be lapped a minimum of 18 inches and the lap
shall be placed in the lower quadrant of the pipe and in such a manner that backfill material
cannot fall into the lap. The polyethylene shall be secured in place with binder twine at not
more than 6-foot intervals. If wrapping is applied before the pipe is placed in the trench,
then special care shall be taken in handling the pipe so that the wrapping will not be
damaged. Care shall also be exercised in backfilling around the pipe and fittings and in
blocking fittings so as not to damage the wrapping. Any wrapping that may be damaged
shall be repaired in a manner satisfactory to the Engineer and so as to form the best
protection to the pipes.
(5) SAND ENCASEMENT
All pipe and fittings that are not enclosed in concrete valve boxes or laid in encasement
pipe, shall be completely encased with a minimum of eight inches (8") of sand on the
bottom and sides of waterlines smaller than 16 inches in diameter, and twelve inches
(12") over the top of the waterline, unless otherwise indicated on the drawings. This
encasement includes the bottom, sides and top of pipe and fittings including bells, so that all
portions will be encased with sand to insulate the pipe from the natural ground and from the
backfill. The sand shall be compacted to a minimum of 90% Standard Proctor density.
Provide twelve inches (12") of sand encasement all around the pipe for 16-inch diameter
and larger waterlines.
Sand shall be placed in a manner that will not injure the polyethylene wrapping and shall be
compacted under, around the side, and over the pipe in a manner that will reduce settlement
to a minimum and as approved by the Engineer.
In order to reduce the amount of sand required, the trench bottom may be excavated in a
rounded manner so as to maintain at least a minimum of eight inches of sand between the
excavation and the pipe (twelve inches for 16-inch diameter and larger waterlines), unless
otherwise indicated on the drawings.
(6) LOWERING PIPE AND ACCESSORIES IN THE TRENCH
a) General: The trench shall be excavated true and parallel to the pipe center line with a
minimum clearance of eight inches below the pipe bottom and with a like clearance
026402
Page 3 of 5
Rev.3-25-2015
from the bottom of the bell to the bottom of the bell hole. The trench shall then be
refilled to the proper grade with sand as specified. The placing of the encasing
material shall be done in such a manner so as to be free of all natural soil rock or other
foreign matter.
After final grading in the trench of the encasing material, bell holes shall be excavated
at each joint.
Proper implements, tools and facilities satisfactory to the Engineer shall be provided
and used by the Contractor for the safe and efficient execution of the work. All pipe,
fittings, valves, hydrants and accessories shall be carefully lowered into the trench by
means of a derrick, ropes or other suitable equipment, in such a manner as to prevent
damage to pipe and fittings. Under no circumstances shall pipe or accessories be
dropped or dumped into the trench.

and adequacy of all sheeting, shoring and bracing. The sheeting, shoring, and bracing shall
be removed as the excavation is backfilled.
Sloping Sides: In unimproved areas where sufficient space is available,the Contractor will
be allowed to back slope the sides of the excavation. The back slope shall be such that the
excavation will be safe from caving. Safety requirements shall govern the back slope used.
De-watering: The Contractor shall keep the excavation free from water by use of
cofferdams,bailing,pumping,well pointing, or any combination, as the particular situation
may warrant. All de-watering devices shall be installed in such a manner as to provide
clearance for construction,removal of forms, and inspection of exterior of form work. It is
the intent of these specifications that the foundation be placed on a firm dry bed. The
foundation bed shall be kept in a de-watered condition for a sufficient period of time to
027205
Page 3 of 6
Rev.3-25-2015
insure the safety of the structure,but in no case shall de-watering be terminated sooner than
seven(7)days after placing concrete. All de-watering methods and procedures are subject to
the approval of the Engineer. The excavation shall be inspected and approved by the
Engineer before work on the structure is started. The Contractor shall provide a relatively
smooth,firm foundation bed for footings and slabs that bear directly on the undisturbed earth
without additional cost to the City, regardless of the soil conditions encountered. The
Engineer will be the sole judge as to whether these conditions have been met. The
Contractor shall pile excavated material in a manner that will not create an unsafe condition.
Unauthorized Over-Excavation: Excavation for slabs, footings, etc., that rest on earth,
shall not be carried below the elevation shown on the drawings. In the event the excavation
is carried below the indicated elevation, the Contractor shall bring the slab, footing, etc., to
the required grade by filling with concrete.
Wall Preparation for Pipe Penetrations: For sanitary sewer application,pipe penetrations
for pipe sizes 4-inch through 15-inch shall be made with appropriately sized core drill bits
recommended by the manufacturer. Pipe penetrations other than described above and as
authorized by the Engineer shall be made as follows: cut shall be equal to the outside
diameter of pipe to pass through it, plus 1/2 inch. Cuts are to be made using electric or
gasoline powered circular saw with masonry blade. Impact type tools shall not be used.
Handling: Manholes shall be handled and stored in a safe manner as necessary to prevent
damaging either the manhole or the surroundings. If manhole must be moved by rolling,the
ground which it traverses shall be smooth and free of rocks, debris, etc. Manholes shall be
lifted as specified by the manufacturer.
Height Adjustment: If necessary, utilize HDPE adjustment rings to adjust the manhole to
the correct grade elevation. A maximum of 18" of adjustment rings may be utilized.
Installation: Lower manhole into wet concrete until it rests at the proper elevation, and a
minimum of six (6) inches into concrete, then plumb.
Backfill Material: Unless shown otherwise on the drawings, initial backfrll around
manholes (from subgrade to five feet (5') above the top of the concrete footing) shall be
flowable grout. The remaining final backfill around manholes shall be cement-stabilized
sand, or approved equal, containing a minimum of 2 sacks of standard Type I or Type II
Portland cement per cubic yard of sand, free of large hard lumps, rock fragments or other
debris. The material shall be free of large lumps or clods which will not readily break down
under compaction. This material shall be subject to approval by the Engineer. Backfill
material shall be free of vegetation or other extraneous material. Topsoil should be
stockpiled separately and used for finish grading around the structure, if necessary.
027205
Page 4 of 6
Rev.3-25-2015
Schedule of Backfilling: The Contractor may begin backfilling around manhole as soon as
the concrete has been allowed to cure and the forms removed.
Compaction: Backfill shall be placed in layers not to exceed 6 inches compacted thickness
and mechanically tamped to at least 95% Standard Proctor density(ASTM D698). Backfill
shall be placed in such a manner as to prevent any wedging action against the structure.
Contractor shall follow operational requirements for bypass pumping as set forth in City
Standard Specification Section 027200 "Control of Wastewater Flows".
5. TESTING
Manholes shall be tested for leakage by either of two tests as specified by the Engineer.
Water Leakage Test:
The Contractor shall provide water, labor, and materials for testing.
Testing shall be as follows:
1. With sewers plugged, the manhole shall be filled with water.
2. The manhole shall be checked after 24 hours have elapsed.
3. Water loss shall not exceed 2.4 gallons per foot of depth for the 24-hour period for
4-foot diameter manholes, or 3.0 gallons per foot of depth for the 24-hour period for
5-foot diameter manholes. Water loss shall not exceed 0.6 gallon per foot of
diameter per foot of depth for the 24-hour period for all sizes of sanitary manholes.
4. If the manhole is within 9 feet of a waterline that is not or cannot be encased, the
manhole shall be tested for no leaks and no noticeable loss of water shall be
experienced for the 24-hour period.
If water loss is excessive,the Contractor shall correct the problem and the manhole shall be retested.
Vacuum Test:
Vacuum testing shall be in accordance with City Standard Specification Section 027203
"Vacuum Testing of Wastewater Manholes and Structures".
6. GRADE ADJUSTMENT OF EXISTING FIBERGLASS MANHOLES
The adjustment of the ring and cover is to be achieved by removal or addition of HDPE grade
adjustment rings that rest above the fiberglass corbel. If the ring and cover must be lowered to the
extent that the new elevation cannot be achieved by removal of adjustment rings and it is necessary
to remove a section of the fiberglass manhole, this work shall be done as described below.
Note that manhole repair kits are available for this work.
Remove the appropriately sized section of the existing manhole from the vertical manhole wall at
least 6 inches below the seam where the corbel meets the vertical wall.
027205

be added to produce the color required. When required by the Engineer, latex adhesive shall be
added to the mortar.
(7) Admixtures
Calcium Chloride will not be permitted. Unless otherwise noted, air-entraining, retarding and
water-reducing admixtures may be used in all concrete and shall conform to the following
requirements:
A "water-reducing, retarding admixture" is defined as a material which, when added to a concrete
mixture in the correct quantity, will reduce the quantity of mixing water required to produce
concrete of a given consistency and will retard the initial set of the concrete.
A "water-reducing admixture" is defined as a material which, when added to a concrete mixture in
the correct quantity, will reduce the quantity of mixing water required to produce concrete of a
030020
Page 4 of 13
Rev.10-30-2014
given consistency.
(a) Retarding and Water-Reducing Admixtures. The admixture shall meet the
requirements for Type A and Type D admixture as specified in ASTM
Designation: C494,modified as follows:
(1) The water-reducing retarder shall retard the initial set of the concrete
a minimum of 2 hours and a maximum of 4 hours, at a specified
dosage rate, at a temperature of 90°F.
(2) The cement used in any series of tests shall be either the cement
proposed for specific work or a "reference" Type I cement from one
mill.
(3) Unless otherwise noted on the plans, the minimum relative durability
factor shall be 80.
The air-entraining admixture used in the referenced and test concrete shall be neutralized Vinsol
resin.
(b) Air-Entraining Admixture. The admixture shall meet the requirements of
ASTM Designation: C260, modified as follows:
(1) The cement used in any series of tests shall be either the cement
proposed for specific work or a "reference" Type I cement from one
mill.
(2) Unless otherwise noted on the plans, the minimum relative durability
factor shall be 80.
The air-entraining admixture used in the referenced concrete shall be neutralized Vinsol resin.
3. STORAGE OF CEMENT
All cement shall be stored in well-ventilated weatherproof buildings or approved bins, which will
protect it from dampness or absorption of moisture. Storage facilities shall be ample, and each
shipment of packaged cement shall be kept separated to provide easy access for identification and
inspection.
The Engineer may permit small quantities of sacked cement to be stored in the open for a maximum
of 48 hours on a raised platform and under waterproof covering.
4. STORAGE OF AGGREGATE
The method of handling and storing concrete aggregate shall prevent contamination with foreign
materials. If the aggregates are stored on the ground, the sites for the stockpiles shall be clear of all
vegetation and level. The bottom layer of aggregate shall not be disturbed or used without
recleaning.
030020
Page 5 of 13
Rev.10-30-2014
When conditions require the use of two or more sizes of aggregates, they shall be separated to
prevent intermixing. Where space is limited, stockpiles shall be separated by physical barriers.
Methods of handling aggregates during stockpiling and subsequent use shall be such that
segregation will be minimized.
Unless otherwise authorized by the Engineer, all aggregate shall be stockpiled at least 24 hours to
reduce the free moisture content.
5. MEASUREMENT OF MATERIALS
The measurement of the materials, except water, used in batches of concrete, shall be by weight.
The fine aggregate, coarse aggregate and mineral filler shall be weighed separately. Where bulk
cement is used, it shall be weighed separately, but batch weighing of sacked cement will not be
required. Where sacked cement is used, the quantities of material per batch shall be based upon
using full bags of cement. Batches involving the use of fractional bags will not be permitted.
Allowance shall be made for the water content in the aggregates.
Bags of cement varying more than 3 percent from the specified weight of 94 pounds may be
rejected, and when the average weight per bag in any shipment, as determined by weighing 50 bags
taken at random, is less than the net weight specified, the entire shipment may be rejected. If the
shipment is accepted, the Engineer will adjust the concrete mix to a net weight per bag fixed by an
average of all individual weights which are less than the average weight determined from the total
number weighed.
6. CLASSIFICATION AND MIX DESIGN
It shall be the responsibility of the Contractor to furnish the mix design, using a coarse aggregate
factor acceptable to the Engineer, for the class(es) of concrete specified. The mix shall be designed
by a qualified concrete technician to conform with the requirements contained herein and in
accordance with the THD Bulletin C-11. The Contractor shall perform, at his own expense, the
work required to substantiate the design, except the testing of strength specimens, which will be
done by the Engineer. Complete concrete design data shall be submitted to the Engineer for
approval.
It shall also be the responsibility of the Contractor to determine and measure the batch quantity of
each ingredient, including all water, so that the mix conforms to these specifications and any other
requirements shown on the plans.
Trial batches will be made and tested using all of the proposed ingredients prior to placing the
concrete, and when the aggregate and/or brand of cement or admixture is changed. Trial batches
shall be made in the mixer to be used on the job. When transit mix concrete is to be used, the trial
designs will be made in a transit mixer representative of the mixers to be used. Batch size shall not
be less than 50 percent of the rated mixing capacity of the truck.
Mix designs from previous or concurrent jobs may be used without trial batches if it is shown that
030020
Page 6 of 13
Rev.10-30-2014
no substantial change in any of the proposed ingredients has been made.
The coarse aggregate factor shall not be more than 0.82, except that when the voids in the coarse
aggregate exceed 48 percent of the total dry loose volume, the coarse aggregate factor shall not
exceed 0.85. The coarse aggregate factor shall not be less than 0.70 for Grades 1, 2 and 3
aggregates.
If the strength required for the class of concrete being produced is not secured with the cement
specified in Table 4, the Contractor may use an approved water-reducing or retarding admixture, or
he shall furnish aggregates with different characteristics which will produce the required results.
Additional cement may be required or permitted as a temporary measure until the redesign is
checked.
Water-reducing or retarding agents may be used with all classes of concrete at the option of the
Contractor.
When water-reducing or retarding agents are used at the option of the Contractor, reduced dosage of
the admixture will be permitted.
Entrained air will be required in accordance with Table 4. The concrete shall be designed to entrain
5 percent air when Grade 2 coarse aggregate is used and 6 percent when Grade 3 coarse aggregate is
used. Concrete as placed in the structure shall contain the proper amount as required above with a
tolerance of plus or minus 1.5 percentage points. Occasional variations beyond this tolerance will
not be cause for rejection. When the quantity of entrained air is found to be above 7 percent with
Grade 2 coarse aggregate or above 8 percent for Grade 3 coarse aggregate, additional test beams or
cylinders will be made. If these beams or cylinders pass the minimum flexural or compressive
requirements, the concrete will not be rejected because of the variation in air content.
7. CONSISTENCY
In cases where the consistency requirements cannot be satisfied without exceeding the maximum
allowable amount of water, the Contractor may use, or the Engineer may require, an approved
water-reducing or retarding agent, or the Contractor shall furnish additional aggregates or
aggregates with different characteristics, which will produce the required results. Additional
cement may be required or permitted as a temporary measure until aggregates are changed and
designs checked with the different aggregates or admixture.
The consistency of the concrete as placed should allow the completion of all finishing operations
without the addition of water to the surface. When field conditions are such that additional
moisture is needed for the final concrete surface finishing operation, the required water shall be
applied to the surface by fog spray only, and shall be held to a minimum. The concrete shall be
workable, cohesive, possess satisfactory finishing qualities, and of the stiffest consistency that can
be placed and vibrated into a homogenous mass. Excessive bleeding shall be avoided. Slump
requirements will be as specified in Table 3.

NOTE: No concrete will be permitted with slump in excess of the maximums shown.
8. QUALITY OF CONCRETE
General
The concrete shall be uniform and workable. The cement content, maximum allowable water-
cement ratio, the desired and maximum slump and the strength requirements of the various classes
of concrete shall conform to the requirements of Table 3 and Table 4 and as required herein.
During the process of the work, the Engineer or his designated representative will cast test cylinders
or beams as a check on the compressive or flexural strength of the concrete actually placed. Test
cylinders must be picked up by the testing lab within 24 hours.
A test shall be defined as the average of the breaking strength of two cylinders or two beams, as the
case may be. Specimens will be tested in accordance with TxDOT Test Methods Tex-418-A or
Tex-420-A.
Test beams or cylinders will be required as specified in the contract documents. For small
placements on structures such as manholes, inlets, culverts, wingwalls, etc., the Engineer may vary
the number of tests to a minimum of one for each 25 cubic yards placed over a several day period.
All test specimens, beams or cylinders, representing tests for removal of forms and/or falsework
shall be cured using the same methods, and under the same conditions as the concrete represented.
"Design Strength"beams and cylinders shall be cured in accordance with THD Bulletin C-11.
The Contractor shall provide and maintain curing facilities as described in THD Bulletin C-11 for
the purpose of curing test specimens. Provision shall be made to maintain the water in the curing
tank at temperatures between 70°F and 90°F.
When control of concrete quality is by twenty-eight-day compressive tests, job control will be by
seven-day compressive tests which are shown to provide the required twenty-eight-day strength,
based on results from trial batches. If the required seven-day strength is not secured with the
030020

9. MIXING CONDITIONS
The concrete shall be mixed in quantities required for immediate use. Any concrete which is not in
place within the limits outlined in City Standard Specification Section 038000 "Concrete
Structures", Article "Placing Concrete-General", shall not be used. Retamping of concrete will not
be permitted.
In threatening weather, which may result in conditions that will adversely affect the quality of the
concrete to be placed, the Engineer may order postponement of the work. Where work has been
started and changes in weather conditions require protective measures, the Contractor shall furnish
adequate shelter to protect the concrete against damage from rainfall, or from freezing temperatures.
If necessary to continue operations during rainfall, the Contractor shall also provide protective
coverings for the material stockpiles. Aggregate stockpiles need be covered only to the extent
necessary to control the moisture conditions in the aggregates to adequately control the consistency
of the concrete.
10. MIXING AND MIXING EQUIPMENT
All equipment, tools, and machinery used for hauling materials and performing any part of the work
shall be maintained in such condition to insure completion of the work underway without excessive
delays for repairs or replacements.

Concrete transported by conveyors shall be protected from sun and wind,if necessary,to prevent loss
of slump and workability. Pipes through which concrete is pumped shall be shaded and/or wrapped
with wet burlap, if necessary, to prevent loss of slump and workability. Concrete shall not be
transported through aluminum pipes, tubes or other aluminum equipment.
Chutes, troughs, conveyors or pipes shall be arranged and used so that the concrete ingredients will
not be separated. When steep slopes are necessary, the chutes shall be equipped with baffle boards
or made in short lengths that reverse the direction of movement, or the chute ends shall terminate in
vertical downspouts. Open troughs and chutes shall extend, if necessary, down inside the forms or
through holes left in them. All transporting equipment shall be kept clean and free from hardened
concrete coatings. Water used for cleaning shall be discharged clear of the concrete.
Each part of the forms shall be filled by depositing concrete as near its final position as possible.
The coarse aggregate shall be worked back from the face and the concrete forced under and around
the reinforcement bars without displacing them. Depositing large quantities at one point and running
or working it along the forms will not be allowed.
Concrete shall be deposited in the forms in layers of suitable depth but not more than 36 inches in
thickness, unless otherwise directed by the Engineer.
The sequence of successive layers or adjacent portions of concrete shall be such that they can be
vibrated into a homogenous mass with the previously placed concrete without a cold j oint. Not more
than one hour shall elapse between adjacent or successive placements of concrete. Unauthorized
construction joints shall be avoided by placing all concrete between the authorized joints in one
continuous operation.
An approved retarding agent shall be used to control stress cracks and/or unauthorized cold joints in
mass placements where differential settlement and/or setting time may induce stress cracking.
Openings in forms shall be provided, if needed, for the removal of laitance of foreign matter of any
kind.
All forms shall be wetted thoroughly before the concrete is placed therein.
All concrete shall be well consolidated and the mortar flushed to the form surfaces by continuous
working with immersion type vibrators. Vibrators which operate by attachment to forms or
reinforcement will not be permitted, except on steel forms. At least one stand-by vibrator shall be
038000
Page 9 of 19
Rev.3-25-2015
provided for emergency use in addition to those required for placement.
The concrete shall be vibrated immediately after deposit. Prior to the beginning of work, a
systematic spacing of the points of vibration shall be established to insure complete consolidation
and thorough working of the concrete around the reinforcement, embedded fixtures, and into the
corners and angles of the forms. Immersion type vibrators shall be inserted vertically,at points 18 to
30 inches apart, and slowly withdrawn. The vibrator may be inserted in a sloping or horizontal
position in shallow slabs. The entire depth of each lift shall be vibrated, allowing the vibrator to
penetrate several inches into the preceding lift. Concrete along construction joints shall be
thoroughly consolidated by operating the vibrator along and close to but not against the joint surface.
The vibration shall continue until thorough consolidation,and complete embedment of reinforcement
and fixtures is produced,but not long enough to cause segregation. Vibration may be supplemented
by hand spading or rodding, if necessary,to insure the flushing of mortar to the surface of all forms.
Slab concrete shall be mixed in a plant located off the structure. Carting or wheeling concrete
batches over completed slabs will not be permitted until they have aged at least four(4)full curing
days. If carts are used,timber planking will be required for the remainder of the curing period. Carts
shall be equipped with pneumatic tires. Curing operations shall not be interrupted for the purpose of
wheeling concrete over finished slabs.
After concrete has attained its initial set,at least one(1)curing day shall elapse before placing strain
on projecting reinforcement to prevent damage to the concrete.
The storing of reinforcing or structural steel on completed roadway slabs generally shall be avoided
and, when permitted, shall be limited to quantities and distribution that will not induce excessive
stresses.
8. PLACING CONCRETE IN COLD WEATHER
(1) Cast-in-Place Concrete. Concrete may be placed when the atmospheric temperature is not less
than 35 degrees F. Concrete shall not be placed in contact with any material coated with frost or
having a temperature less than 32 degrees F.
Aggregates shall be free from ice, frost and frozen lumps. When required, in order to produce the
minimum specified concrete temperature,the aggregate and/or the water shall be heated uniformly,
in accordance with the following:
The water temperature shall not exceed 180 degrees F,and/or the aggregate temperature shall
not exceed 150 degrees F. The heating apparatus shall heat the mass of aggregate uniformly.
The temperature of the mixture of aggregates and water shall be between 50 degrees F and 85
degrees F before introduction of the cement.
All concrete shall be effectively protected as follows:
(a) The temperature of slab concrete of all unformed surfaces shall be maintained
at 50 degrees F or above for a period of 72 hours from time of placement and above
40 degrees F for an additional 72 hours.
038000
Page 10 of 19
Rev.3-25-2015
(b) The temperature at the surface of all concrete in piers, culverts walls,retaining
walls,parapets,wingwalls,bottoms of slabs,and other similar formed concrete shall
be maintained at 40 degrees F or above for a period of 72 hours from time of
placement.
(c) The temperature of all concrete, including the bottom slabs of culverts placed
on or in the ground, shall be maintained above 32 degrees F for a period of 72 hours
from time of placement.
Protection shall consist of providing additional covering, insulated forms or other means, and if
necessary, supplementing such covering with artificial heating. Curing as specified under Article
"Curing Concrete"of this specification shall be provided during this period until all requirements for
curing have been satisfied.
When impending weather conditions indicate the possibility of the need for such temperature
protection, all necessary heating and covering material shall be on hand ready for use before
permission is granted to begin placement.
Sufficient extra test specimens will be made and cured with the placement to ascertain the condition
of the concrete as placed, prior to form removal and acceptance.
(2) Precast Concrete. A fabricating plant for precast products which has adequate protection from
cold weather in the form of permanent or portable framework and covering, which protects the
concrete when placed in the forms, and is equipped with approved steam curing facilities,may place
concrete under any low temperature conditions provided:
(a) The framework and covering are placed and heat is provided for the concrete and the
forms within one hour after the concrete is placed. This shall not be construed to be one hour
after the last concrete is placed,but that no concrete shall remain unprotected longer than one
hour.
(b) Steam heat shall keep the air surrounding the concrete between 50 degrees F and 85
degrees F for a minimum of three hours prior to beginning the temperature rise which is
required for steam curing.
(c) For fabricating plants without the above facilities and for job site precast products,the
requirements of the Article "Curing Concrete" of this specification shall apply.
The Contractor is responsible for the protection of concrete placed under any and all weather
conditions. Permission given by the Engineer for placing concrete during freezing weather will in no
way relieve the Contractor of the responsibility for producing concrete equal in quality to that placed
under nonnal conditions. Should concrete placed under such conditions prove unsatisfactory,it shall
be removed and replaced at no additional cost.
038000
Page 11 of 19
Rev.3-25-2015
9. PLACING CONCRETE IN WATER
Concrete shall be deposited in water only when specified on the plans or with written permission by
the Engineer. The forms or cofferdams shall be sufficiently tight to prevent any water current
passing through the space in which the concrete is being deposited. Pumping will not be permitted
during the concrete placing, nor until it has set for at least 36 hours.
The concrete shall be placed with a tremie, closed bottom-dump bucket, or other approved method,
and shall not be permitted to fall freely through the water nor shall it be disturbed after it has been
placed. The concrete surface shall be kept approximately level during placement.
The tremie shall consist of a water-tight tube 14 inches or less in diameter. It shall be constructed so
that the bottom can be sealed and opened after it is in place and fully charged with concrete. It shall
be supported so that it can be easily moved horizontally to cover all the work area and vertically to
control the concrete flow.
Bottom-dump buckets used for underwater placing shall have a capacity of not less than one-half
cubic yard. It shall be lowered gradually and carefully until it rests upon the concrete already placed
and raised very slowly during the upward travel; the intent being to maintain still water at the point
of discharge and to avoid agitating the mixture.
The placing operations shall be continuous until the work is complete.
10. PLACING CONCRETE IN BOX CULVERTS
In general, construction joints will be permitted only where shown on the plans.
Where the top slab and walls are placed monolithically in culverts more than 4 feet in clear height,
an interval of not less than one (1) nor more than two (2)hours shall elapse before placing the top
slab to allow for shrinkage in the wall concrete.
The base slab shall be finished accurately at the proper time to provide a smooth uniform surface.
Top slabs which carry direct traffic shall be finished as specified for roadway slabs in Article"Finish
of Roadway Slabs". Top slabs of fill type culverts shall be given a reasonably smooth float finish.
11. PLACING CONCRETE IN FOUNDATIONS AND SUBSTRUCTURE
Concrete shall not be placed in footings until the depth and character of the foundation has been
inspected by the Engineer and permission has been given to proceed.
Placing of concrete footings upon seal concrete courses will be permitted after the caissons or
cofferdams are free from water and the seal concrete course cleaned. Any necessary pumping or
bailing during the concreting operation shall be done from a suitable sump located outside the forms.
All temporary wales or braces inside cofferdams or caissons shall be constructed or adjusted as the
work proceeds to prevent unauthorized construction joints in footings or shafts.
038000
Page 12 of 19
Rev.3-25-2015
When footings can be placed in a diy excavation without the use of cofferdams or caissons, forms
may be omitted,if desired by the Contractor and approved by the Engineer,and the entire excavation
filled with concrete to the elevation of the top of footing; in which case,measurement for payment
will be based on the footing dimensions shown on the plans.
12. TREATMENT AND FINISHING OF HORIZONTAL SURFACES EXCEPT ROADWAY
SLABS
All unformed upper surfaces shall be struck off to grade and finished. The use of mortar topping for
surfaces under this classification will not be permitted.
After the concrete has been struck off, the surface shall be floated with a suitable float. Sidewalks
shall be given a wood float or broom finish, or may be striped with a brush, as specified by the
Engineer. Other surfaces shall be wood float finished and striped with a fine brush leaving a fine-
grained texture.
13. FINISH OF ROADWAY SLABS
As soon as the concrete has been placed and vibrated in a section of sufficient width to permit
working,the surface shall be approximately leveled,struck off and screeded,carrying a slight excess
of concrete ahead of the screed to insure filling of all low spots. The screed shall be designed rigid
enough to hold true to shape and shall have sufficient adjustments to provide for the required
camber. A vibrating screed may be used if heavy enough to prevent undue distortion. The screeds
shall be provided with a metal edge.
Longitudinal screeds shall be moved across the concrete with a saw-like motion while their ends rest
on headers or templates set true to the roadway grade or on the adjacent finished slab.
The surface of the concrete shall be screeded a sufficient number of times and at such intervals to
produce a uniform surface, true to grade and free of voids.
If necessary, the screeded surface shall be worked to smooth finish with a long handled wood or
metal float of the proper size, or hand floated from bridges over the slab.
When required by the Engineer, the Contractor shall perform sufficient checks with a long handled
10-foot straightedge on the plastic concrete to insure that the final surface will be within the
tolerances specified below. The check shall be made with the straightedge parallel to the centerline.
Each pass thereof shall lap half of the preceding pass. All high spots shall be removed and all
depressions over one-sixteenth inch(1/16")in depth shall be filled with fresh concrete and floated.
The checking and floating shall be continued until the surface is true to grade and free of
depressions, high spots, voids or rough spots.
Rail support holes shall be filled with concrete and finished to match the top of the slab.
Surface Texturing.
Perform surface texturing using a either carpet drag or metal tining as indicated on the drawings.
Complete final texturing before the concrete has attained its initial set. Draw the carpet drag
038000
Page 13 of 19
Rev.3-25-2015
longitudinally along the pavement surface with the carpet contact surface area adjusted to provide a
satisfactory coarsely textured surface. A metal-tine texture finish is required using a tining machine
unless otherwise shown on the plans. Provide the metal-tine finish immediately after the concrete
surface has set enough for consistent tining. Operate the metal-tine device to obtain grooves spaced
at 1 in., approximately 3/16 in. deep, with a minimum depth of 1/8 in., and approximately 1/12 in.
wide. Do not overlap a previously tined area. Use manual methods for achieving similar results on
ramps and other irregular sections of pavements. Repair damage to the edge of the slab and joints
immediately after texturing. Do not tine pavement that will be overlaid.
Upon completion of the floating and/or straight edging and before the disappearance of the moisture
sheen, the surface shall be given a broom or burlap drag finish. The grooves of these finishes shall
be parallel to the structure centerline. It is the intent that the average texture depth resulting from the
number of tests directed by the Engineer be not less than 0.035 inch with a minimum texture depth of
0.030 inch for anyone test when tested in accordance with TxDOT Test Method Tex-436-A. Should
the texture depth fall below that intended, the finishing procedures shall be revised to produce the
desired texture.
After the concrete has attained its final set, the roadway surface shall be tested with a standard 10-
foot straightedge. The straightedge shall be placed parallel to the centerline of roadway to bridge any
depressions and touch high spots. Ordinates of irregularities measured from the face of the
straightedge to the surface of the slab shall not exceed one-eighth of an inch(1/8"),making proper
allowances for camber,vertical curvature and surface texture. Occasional variations,not exceeding
three-sixteenth of an inch (3/16") will be acceptable, if in the opinion of the Engineer it will not
affect the riding qualities.
When directed by the Engineer, irregularities exceeding the above requirements shall be corrected.
In all roadway slab finishing operations,camber for specified vertical curvature and transverse slopes
shall be provided.
14. CURING CONCRETE
The Contractor shall inform the Engineer fully of the methods and procedures proposed for curing;
shall provide the proper equipment and material in adequate amounts; and shall have the proposed
methods, equipment and material approved prior to placing concrete.
Inadequate curing and/or facilities, therefore,shall be cause for the Engineer to stop all construction
on the job until remedial action is taken. All concrete shall be cured for a period of four(4) curing
days except as noted herein.
038000

Rev.3-25-2015
EXCEPTIONS TO 4-DAY CURING
Description Required Curing
Upper Surfaces of Bridge Slabs and 8 curing days (Type I or III) cement
Top Slabs of Direct Traffic Culverts 10 curing days (Type II cement)
Concrete Piling (non-prestressed) 6 curing days
When the air temperature is expected to drop below 35 degrees F,the water curing mats shall
be covered with polyethylene sheeting, burlap-polyethylene blankets or other material to
provide the protection required by Article "Placing Concrete in Cold Weather" of these
specifications.
A curing day is defined as a calendar day when the temperature, taken in the shade away from
artificial heat, is above 50 degrees F for at least 19 hours (colder days if satisfactory provisions are
made to maintain the temperature of all surfaces of the concrete above 40 degrees F for the entire 24
hours). The required curing period shall begin when all concrete therein has attained its initial set.
The following methods are permitted for curing concrete subject to the restrictions of Table 1 and the
following requirements for each method of curing.
(1) Form Curing. When forms are left in contact with the concrete, other curing methods will not
be required except for cold weather protection.
(2) Water Curing. All exposed surfaces of the concrete shall be kept wet continuously for the
required curing time. The water used for curing shall meet the requirements for concrete mixing
water as specified in the specification Section 030020 "Portland Cement Concrete". Seawater will
not be permitted. Water which stains or leaves an unsightly residue shall not be used.
(a) Wet Mat. Cotton mats shall be used for this curing method. They shall be placed as
soon as possible after the surface has sufficiently hardened to prevent damage to the concrete.
(See Article, 'Placing Concrete" of this specification.) Damp burlap blankets made from
nine-ounce stock may be placed on the damp concrete surface for temporary protection prior
to the application of the cotton mats which may be placed dry and wetted down after
placement.
The mats shall be weighted down adequately to provide continuous contact with all concrete
surfaces where possible. The surfaces of the concrete shall be kept wet for the required
curing time. Surfaces which cannot be cured by contact shall be enclosed with mats and
anchored positively to the forms or to the ground so that outside air cannot enter the
enclosure. Sufficient moisture shall be provided inside the enclosure to keep all surfaces of
the concrete wet.
(b) Water Spray. This curing method shall consist of overlapping sprays or sprinklers that
keep all unformed surfaces continuously wet.
(c) Pondin . This curing method requires the covering of the surfaces with a minimum of
two inches (2") of clean granular material, kept wet at all times, or a minimum of one-inch
038000
Page 15 of 19
Rev.3-25-2015
(1") depth of water. Satisfactory provisions shall be made to provide a dam to retain the
water or saturated granular material.
(3) Membrane Curing. This consists of curing concrete pavement,concrete pavement(base),curbs,
gutters, retards, sidewalks, driveways, medians, islands, concrete riprap, cement-stabilized riprap,
concrete structures and other concrete as indicated on the plans by impervious membrane method.
Unless otherwise provided herein or shown on the plans, either Type 1-D or Type 2 membrane
curing compound may be used where permitted except that Type 1-D (Resin Base Only) will be
required for slab concrete in bridge decks and top slabs of direct traffic culverts.

Rev.3-25-2015
Membrane curing shall not be applied to dry surfaces,but shall be applied just after free moisture has
disappeared. Formed surfaces and surfaces which have been given a first rub shall be dampened and
shall be moist at the time of application of the membrane.
When membrane is used for complete curing, the film shall remain unbroken for the minimum
curing period specified. Membrane which is damaged shall be corrected immediately by
reapplication of membrane. Unless otherwise noted herein or on the plans,the choice of membrane
type shall be at the option of the Contractor. Only one type of curing compound will be permitted on
any one structure.
The membrane curing compound shall be applied after the surface finishing has been completed,and
immediately after the free surface moisture has disappeared. The surface shall be sealed with a
single uniform coating of curing compound applied at the rate of coverage recommended by the
manufacturer and directed by the Engineer, but not less than 1 gallon per 180 square feet of area.
The Contractor shall provide satisfactory means and facilities to properly control and check the rate
of application of the compound.
The compound shall be thoroughly agitated during its use and shall be applied by means of approved
mechanical power pressure sprayers. The sprayers used to apply the membrane to concrete pavement
or concrete pavement (base) shall travel at uniform speed along the forms and be mechanically
driven. The equipment shall be of such design that it will insure uniform and even application of the
membrane material. The sprayers shall be equipped with satisfactory atomizing nozzles. Only on
small miscellaneous items will the Contractor be permitted to use hand-powered spray equipment.
For all spraying equipment, the Contractor shall provide facilities to prevent the loss of the
compound between the nozzle and the concrete surface during the spraying operations.
The compounds shall not be applied to a dry surface. If the surface of the concrete has become dry,
it shall be moistened prior to application of membrane by fogging or mist application. Sprinkling or
coarse spraying will not be allowed.
At locations where the coating shows discontinuities,pinholes or other defects,or if rain falls on the
newly-coated surface before the film has dried sufficiently to resist damage,an additional coat of the
compound shall be applied immediately at the same rate of coverage specified herein.
To insure proper coverage, the Engineer shall inspect all treated areas after application of the
compound for the period of time designated in the governing specification for curing, either for
membrane curing or for other methods. Should the foregoing indicate that any area during the curing
period is not protected, an additional coat or coats of the compound shall be applied immediately,
and the rate of application of the membrane compound shall be increased until all areas are
uniformly covered.
When temperatures are such as to warrant protection against freezing,curing by this method shall be
supplemented with an approved insulating material capable of protecting the concrete for the
specified curing period.
If at any time there is reason to believe that this method of curing is unsatisfactory or is detrimental
038000
Page 17 of 19
Rev.3-25-2015
to the work,the Contractor,when notified, shall immediately cease the use of this method and shall
change to curing by one of the other methods specified under this contract.
15. REMOVAL OF FORMS
Except as herein provided, forms for vertical surfaces may be removed when the concrete has aged
not less than one day(24 hours)when Type I and Type II cement is used, and not less than one-half
day (12 hours) when Type III cement is used, provided it can be done without damage to the
concrete.
Forms for inside curb faces may be removed in approximately three hours provided it can be done
without damage to the curb.
16. FINISHING EXPOSED SURFACES
Concrete shall be finished as required in the specification Section for the respective item or as
otherwise specified on the plans.
An ordinary surface finish shall be applied to all concrete surfaces either as a final finish or
preparatory to a higher finish.
Ordinary Surface Finish shall be as follows:
After form removal,all porous or honey-combed areas and spalled areas shall be corrected by
chipping away all loose or broken material to sound concrete.
Feather edges shall be eliminated by cutting a face perpendicular to the surface. Shallow
cavities shall be repaired using adhesive grout or epoxy grout. If judged repairable by the
Engineer, large defective areas shall be corrected using concrete or other material approved
by the Engineer.
Holes and spalls caused by removal of metal ties, etc., shall be cleaned and filled with
adhesive grout or epoxy grout. Exposed parts of metal chairs on surfaces to be finished by
rubbing, shall be chipped out to a depth of one-half inch (1/2") and the surface repaired.
All fins,runs, drips or mortar shall be removed from surfaces which remain exposed. Form
marks and chamfer edges shall be smoothed by grinding and/or dry rubbing.
Grease, oil, dirt, curing compound, etc., shall be removed from surfaces requiring a higher
grade of finish. Discolorations resulting from spillage or splashing of asphalt,paint or other
similar material shall be removed.
Repairs shall be dense, well bonded and properly cured, and when made on surfaces which
remain exposed and do not require a higher finish, shall be finished to blend with the
surrounding concrete.

The boring locations were selected by PSI personnel and located in the field using a recreational-grade GPS
system. Elevations of the ground surface at the boring locations were not provided and should be surveyed
by others prior to construction, if required. We have estimated ground surface elevations at the boring
locations from the topographic survey provided (or from Google Earth) and estimate an approximate 1 foot
accuracy.The references to elevations of various subsurface strata are based on depths below existing grade
at the time of drilling.The approximate boring locations are depicted on the Boring Location Plan provided in
the Appendix.

The boring logs included in the Appendix should be reviewed for specific information at individual boring
locations. The boring logs include soil descriptions, stratifications, locations of the samples, and field and
laboratory test data.The descriptions provided on the logs only represent the conditions at the specific boring
location;the stratifications represent the approximate boundaries between subsurface materials.The actual
transitions between strata may be more gradual and less distinct. Variations will occur and should be
expected across the site.
2.5.1 GROUNDWATER INFORMATION
Water level measurements were performed during drilling and after completion of drilling. Specific
information concerning groundwater is noted on each boring log presented in the Appendix of this report.
Groundwater was encountered during the field investigation of this site.
Groundwater was measured at a depth of about 13.5 feet during drilling and 12 feet after completion of the
drilling.The groundwater measurements are summarized in the following table:

Groundwater levels fluctuate seasonally as a function of rainfall, proximity to creeks, rivers and lakes, the
infiltration rate of the soil,seasonal and climatic variations and land usage. In relatively pervious soils,such as
sandy soils, the indicated depths are a relatively reliable indicator of groundwater levels. In relatively
impervious soils, water levels observed in the borings may not provide a reliable indication of groundwater
elevations, even after several days. If a detailed water level evaluation is required, observation wells or
piezometers should be installed at the site to monitor water levels.
The groundwater levels presented in this report were measured at the time of PSI field activities. The
contractor should be prepared to control groundwater, if encountered, during construction.

3.0 GEOTECHNICAL EVALUATION AND RECOMMENDATIONS
3.1 GEOTECHNICAL DISCUSSION
The geotechnical recommendations presented in this report have been developed based on the subsurface
conditions encountered and PSI's understanding of the project. Should changes in the project criteria occur,
a review should be made by PSI to determine if modifications to the recommendations will be required.
Our borings did not indicate groundwater in areas when excavations are 10 feet or less from ground surface
following completion of the drilling.
For temporary retaining purposes,we have included lateral earth pressure information for various soil types
encountered along the alignment.
The following design recommendations have been developed based on the previously described project
characteristics and subsurface conditions encountered. If there are changes in the project criteria, PSI should
be retained to determine if modifications in the recommendations will be required. The findings of such a
review would be presented in a supplemental report.Once final design plans and specifications are available,
a general review by PSI is recommended to observe that the conditions assumed in the project description
are correct and to verify that the earthwork and foundation recommendations are properly interpreted and
implemented within the construction documents.
3.2 PIPELINE DESIGN CONSIDERATION
The pipeline design consideration should include the overburden soil pressure on the pipe material. Pressure
from surficial dead and live loads above the overburden are not anticipated to be significant due to the
anticipated depth of pipe installation (4 feet minimum). If the preceding is not the case, it should be
accommodated in the pipe cross-section and material type selection.
3.2.1 EXCAVATIONS-LATERAL EARTH PRESSURE
Soils excavated along the pipeline alignment can be stockpiled adjacent to the excavations, but sufficiently
distant so as not to add loading to the excavation sidewalls/slopes. PSI recommends that the temporary
structures that retain excavations (trench boxes if used) be designed to resist lateral earth pressures.
Equivalent lateral earth pressure values for both at-rest and active earth pressure conditions are shown in
the following tables.

3.2.2 OSHA SOIL CLASSIFICATION FOR BORE PIT EXCAVATION
The subsoils can be classified in general accordance with OSHA Health and Safety Standards for Excavations,
29 CFR Part 1926,dated October 31,1989.OSHA soil classification system categorizes the soil and rock in four
types based on shear strength and stability.Based on our geotechnical exploration and laboratory test results,
details of soil classification at each boring are summarized in the following table. Additional geotechnical
design parameters presented in the Appendix for consideration.

3.3 GROUNDWATER CONSIDERATIONS
Groundwater depths in the exploratory borings during our field exploration are near the 12 to 13.5 foot
depths.Wellpoint dewatering for deeper excavations(if needed)will likely be required.
Depending on the pipe material type, size, and depth of installation, uplift and buoyant forces may be of
concern when groundwater is present around the pipe and should be considered in the design but may be
significantly proportional to the increase in pipe size. When an empty pipe is placed below the groundwater
table, the bottom may be subjected to the uplift force equal to 62.4 pounds per square foot for each cubic
foot of pipe below the water table and will be at the maximum when the pipe is empty. If design requires
uplift considerations,uplift forces may be resisted bythe mass of the pipe,buried concrete dead man anchors,
if feasible, and by the weight of the overburden soils above the pipeline installation.

4.0 PAVEMENT DESIGN RECOMMENDATIONS
4.1 PAVEMENT DESIGN PARAMETERS
PSI understands that flexible and rigid pavements will be considered for this project. PSI utilized the "City
of Corpus Christi Infrastructure Design Manual' and the "AASHTO Guide for Design of Pavement
Structures" published by the American Association of State Highway and Transportation Officials to
evaluate the pavement thickness recommendations in this report. This method of design considers
pavement performance, traffic, roadbed soil, pavement materials, environment, drainage and reliability.
Each of these items is incorporated into the design methodology.
We have not been provided with traffic counts for this street. We are assuming streets would be classified
as a C2 Collector. Based on Table 6.3.3A "Pavement Design Specifications" of the current City of Corpus
Christi IDM,this street type requires a 30-year design section based on 2,000,000 18 kip ESALs.
Based on this information, PSI is providing recommended pavement sections for both flexible HMAC and
rigid concrete pavement options. Details regarding the basis for this design are presented in the table
below
TABLE 4.1: PAVEMENT DESIGN PARAMETERS AND ASSUMPTIONS(FLEXIBLE)
Reliability,percent 90
Length of Service Life,Years 30
Initial Serviceability Index,Flexible Pavement 4.2
Terminal Serviceability Index 2.5

Standard Deviation,Flexible Pavement 0.45
Subgrade California Bearing Ratio(CBR) 2.0 for clay subgrade
Subgrade Modulus of Subgrade Reaction, k in pci 240 for lime/cement stabilized clay subgrade
Asphaltic concrete pavements founded on top of expansive soils will be subjected to PVM soil movements
estimated and presented in this report(i.e.2% inches).These potential soil movements are typically activated
to some degree during the life of the pavement. Consequently, pavements can be expected to crack and
require periodic maintenance to reduce damage to the pavement structure.
During the paving life, maintenance to seal surface cracks within concrete or asphalt paving and to reseal
joints within concrete pavement should be undertaken to achieve the desired paving life. Perimeter drainage
should be controlled to prevent or retard influx of surface water from areas surrounding the paving. Water
penetration leads to paving degradation.Water penetration into base or subgrade materials,sometimes due
to irrigation or surface water infiltration leads to pre-mature paving degradation.
The City of Corpus Christi requires the base and subgrade to be extended beneath the curb and gutter and to
2 feet behind the Curb. In accordance with City Standard Spec 025612 (Concrete Curb and Gutter)there is a
requirement for compaction behind the Curb within 48 hours of removing forms.
Material specifications,construction considerations,and section requirements are presented in the following
sections.

Corpus Christi,Texas September 8,2025
The presented recommended pavement sections are based on the field and laboratory test results for the
project, local pavement design practice, design assumptions presented herein and previous experience with
similar projects.The project Civil Engineer should verify that the ESAL and other design values are appropriate
for the expected traffic and design life of the project. PSI should be notified in writing if the assumptions or
design parameters are incorrect or require modification.
4.2 PAVEMENT SECTION RECOMMENDATIONS
The soil conditions in this area generally consists of a highly plasticity sandy clay subgrade. The PI of the
sandy clay is approximately 40. Table 6.3.51D of the current City of Corpus Christi IDM indicates that this
is a Clay Type A3 soil type. We recommend lime/cement stabilization for the subgrade or lime stabilization
only for the flexible pavement option if a geogrid is utilized as part of the pavement design section.
4.2.1 FLEXIBLE PAVEMENT
The proposed roadways and parking areas for this project may be constructed with flexible asphaltic concrete
pavement. Recommendations for flexible asphaltic concrete pavement for roadways and parking areas are
provided below.

5.0 CONSTRUCTION CONSIDERATIONS
Having a Geotechnical Engineer retained to review the earthwork recommendations in the Contract
Documents and be an active participant in team meetings near the time of construction can often result in
project cost savings. Therefore, PSI recommends that an AASHTO accredited 3rd party laboratory with
qualified professional engineers who specialize in geotechnical engineering be retained to provide
observation and testing of construction activities involved in the foundations, earthwork, pavements and
related activities of this project.As the Geotechnical Engineer of Record (GER), PSI's services can be retained
as the 3rd party laboratory. PSI's participation would be advantageous to the project flow and value
engineering during construction since we are most familiar with the existing soil conditions at the site.
The geotechnical engineer often does not have available all design information at the time of writing the
original report since the report is done very early in the design process. The GER can be of great benefit
immediately prior to construction since definitive information regarding the location of the building,
surrounding flatwork, pavements, planned landscaping, and drainage features is available at that time.The
GER can then write Supplement letters to the original geotechnical report often resulting in less risk and
significant project cost savings.
PSI cannot accept responsibility for conditions which deviate from those described in this report, nor for the
performance of the foundations or pavements if not engaged to also provide construction observation and
materials testing for this project. The PSI geotechnical engineer of record should also be engaged by the
Design Team during construction,even if periodic on-call testing is contracted with PSI Construction Services.
5.1 INITIAL SITE PREPARATION CONSIDERATIONS
5.1.1 SUBGRADE PREPARATION FOR SITE WORK
Grade adjustments outside of the building pad and pavement areas can be made using select or general fill
materials.The clean excavated onsite soils may also be reused in areas not sensitive to movement.

5.1.2 EXISTING SITE CONDITIONS
The following table outlines construction considerations in consideration of demolition of existing structures,
demolition of existing paving, procedures for abandoning old utility lines and removing trees.

Abandoned Utilities

Utilities of former structures located outside of footprint
Abandon in place using a grout plug
of proposed structure
5.2 MOISTURE SENSITIVE SOILS/WEATHER RELATED CONCERNS
Soils are sensitive to disturbances caused by construction traffic and changes in moisture content. During wet
weather periods, increases in the moisture content of the soil can cause significant reduction in the soil
strength and support capabilities. In addition, soils which become wet may be slow to dry and thus
significantly retard the progress of grading and compaction activities. It will, therefore, be advantageous to
perform earthwork,foundation, and construction activities during dry weather.
5.3 EXCAVATION OBSERVATIONS
Excavations should be observed by a representative of PSI prior to continuing construction activities in those
areas. PSI needs to assess the encountered materials and confirm that site conditions are consistent with
those discussed in this report. This is especially important to identify the condition and acceptability of the
exposed subgrades under foundations and other structures that are sensitive to movement.Soft or loose soil
zones encountered at the bottom of the excavations should be removed to the level of competent soils as
directed by the Geotechnical Engineer or their representative. Cavities formed as a result of excavation of
soft or loose soil zones should be backfilled with compacted select fill or lean concrete.
After opening,excavations should be observed,and concrete should be placed as quickly as possible to avoid
exposure to wetting and drying. Surface run-off water should be drained away from the excavations and not
PAGE 15 Lon
n
Proposed 16-inch Water Main Extension Hwy 286 to Alameda PSI Project No:0312-3623
Corpus Christi,Texas September 8,2025
be allowed to pond. Excavations left open for more than 48 hours should be protected to reduce evaporation
or entry of moisture.
5.4 DRAINAGE CONSIDERATIONS
Water should not be allowed to collect in or adjacent to foundation excavations, on foundation surfaces, or
on prepared subgrades within the construction area during or after construction. Proper drainage around
grade-supported sidewalks and flatwork is important to reduce potential movements. Excavated areas should
be sloped toward one corner to facilitate removal of collected rainwater, groundwater, or surface runoff.
Providing rapid, positive drainage away from the building reduces moisture variations within the underlying
soils and will aid in reducing the magnitude of potential movements.
5.5 EXCAVATIONS AND TRENCHES
Excavation equipment capabilities and field conditions may vary. Geologic processes are erratic and large
variations can occur in small vertical and/or lateral distances. Details regarding "means and methods" to
accomplish the work (such as excavation equipment and technique selection) are the sole responsibility of
the project contractor. The comments contained in this report are based on small diameter borehole
observations. The performance of large excavations may differ as a result of the differences in excavation
sizes.
The Occupational Safety and Health Administration (OSHA) Safety and Health Standards (29 CFR Part 1926,
Revised October 1989), require that excavations be constructed in accordance with the current OSHA
guidelines. Furthermore, the State of Texas requires that detailed plans and specifications meeting OSHA
standards be prepared for trench and excavation retention systems used during construction. PSI
understands that these regulations are being strictly enforced,and if they are not closely followed,the owner
and the contractor could be liable for substantial penalties.
The contractor is solely responsible for designing and constructing stable,temporary excavations and should
shore, slope, or bench the sides of the excavations as required to maintain stability of both the excavation
sides and bottom.The contractor's"responsible person",as defined in 29 CFR Part 1926,should evaluate the
soil exposed in the excavations as part of the contractor's safety procedures. In no case should slope height,
slope inclination, or excavation depth, including utility trench excavation depth, exceed those specified in
local,State, and Federal safety regulations.
PSI is providing this information as a service to the client. PSI does not assume responsibility for construction
site safety or the contractor's or other parties' compliance with local, State, and Federal safety or other
regulations.A trench safety plan was beyond the scope of our services for this project.

6.0 REPORT LIMITATIONS
The recommendations submitted in this report are based on the available subsurface information obtained
by PSI and design details furnished by the client for the proposed project. If there are revisions to the plans
for this project, or if deviations from the subsurface conditions noted in this report are encountered during
construction,PSI should be notified immediately to determine if changes in the foundation recommendations
are required. If PSI is not notified of such changes, PSI will not be responsible for the impact of those changes
on the project.
The Geotechnical Engineer warrants that the findings, recommendations, specifications, or professional
advice contained herein have been made in accordance with generally accepted professional Geotechnical
Engineering practices in the local area. No other warranties are implied or expressed.This report may not be
copied without the expressed written permission of PSI.
After the plans and specifications are more complete, the Geotechnical Engineer should be retained and
provided the opportunity to review the final design plans and specifications to check that the engineering
recommendations have been properly incorporated in the design documents. At this time, it may be
necessary to submit supplementary recommendations. If PSI is not retained to perform these functions, PSI
will not be responsible for the impact of those conditions on the project.
This report has been prepared for the exclusive use of the City of Corpus Christi for specific application to the
proposed 16-inch Water Main Extension Hwy. 286 to Alameda to be constructed at Corpus Christi,Texas.
