performance or furnishing of the Work, (d) study and carefully correlate Bidder's
observations with the Contract Documents, and (e) notify Engineer of all conflicts,
errors or discrepancies in the Contract Documents. Failure to make these
examinations shall in no way relieve any Bidder from the responsibility of fulfilling
all of the terms of the contract, without additional cost to the OWNER.
6.2 Information and data reflected in the Contract Documents with respect to
Underground Facilities at or contiguous to the site is based upon information and
data furnished to the Owner by Owners of such underground Facilities or others,
and the Owner does not assume responsibility for the accuracy or completeness
thereof. All existing structures, improvements, and utilities shall be adequately
protected, at the expense of the Contractor, from damage that might otherwise
occur due to construction operations. Where construction comes in close
proximity to existing structures or utilities, or if it becomes necessary to move

The utility lines and other existing structures shown on the plans are for
information only and are not guaranteed by the City to be complete or accurate as

6.5 The lands upon which the Work is to be performed, rights-of-way and easements
for access thereto and other lands designated for use by Contractor in performing
the Work, are identified in the Contract documents.
6.6 The submission of a Bid will constitute an incontrovertible representation by Bidder
that Bidder has complied with every requirement of this Article 6, that without
exception the Bid is premised upon performing and furnishing the work required by
the Contract Documents and such means, methods, techniques, sequences or
procedures of construction as may be indicated in or required by the Contract
Documents, and that the Contract Documents are sufficient in scope and detail to
indicate and convey understanding of all terms and conditions for performance and
furnishing of the Work.

statement with pertinent information regarding similar projects and other evidence
of qualification for each such Subcontractor, supplier, person or organization if

objection to any proposed Subcontractor, Supplier, other person or organization,
Owner may, before the Notice of Award is given, request the apparent Successful
Bidder to submit an acceptable substitute in which case the apparent Successful
Bidder shall submit an acceptable substitute. Bidder's Bid price may be increased
(or decreased) by the difference in cost occasioned by such substitution, and the

contract award.
If the apparent Successful Bidder declines to make any such substitution, the
Owner may award the contract to the next lowest Bidder that proposes to use
acceptable Subcontractors, Suppliers, other persons and organizations. The
declining to make requested substitutions will not constitute grounds for sacrificing
the Bid security of any Bidder.

reserves the right to reject the Bid of any Bidder if the Owner believes that it would
not be in the best interest of the Project to make an award to that Bidder, whether
because the Bid is not responsive or the Bidder is unqualified or has doubtful
financial ability or fails to meet any other pertinent standard or criteria established

CONTRACTOR represents that no employee or officer of the City has an
interest in the CONTRACTOR.”
ITEM 107.14 - STATE AND LOCAL SALES AND USE TAXES
SC-107.14
Delete the language in Item 107.14 in its entirety and substitute the following in lieu
thereof:
“Recent legislation has removed the sales tax exemption previously provided by
Section 151.311 of the Tax Code covering tangible personal property purchased by
a contractor for use in the performance of a contract for the improvement of City-
owned realty.
It is still possible, however, for a contractor to make tax-free purchase of tangible
personal property, which will be incorporated into and become part of a City
construction project through the use of a "separated contract" with the City. A
"separated contract" is one, which separates charges for materials from charges for
labor. Under such a contract, the contractor becomes a "seller" of those materials,
which are incorporated into the project, such as bricks, lumber, concrete, paint, etc.
The contractor issues a resale certificate in lieu of paying the sales tax at the time
such items are purchased. The contractor then receives an exemption certificate
from the city for those materials. (This procedure may not be used, however, for
materials, which do not become a part of the finished product. For example,
equipment rentals, form materials, etc. are not considered as becoming
"incorporated" into the project).
Utilization of this "separated contract" approach eliminates the need for bidders to
figure in sales tax for materials, which are to be incorporated into the project. The
successful bidder's bid form will be used to develop the "separated contract" and will
determine the extent of the tax exemption. Upon execution of the construction
contract, the CONTRACTOR shall furnish a breakdown (per item) of:
1) materials incorporated into the project; and
2) labor, equipment, supervision and materials not incorporated into the
project.”
ITEM 107.19 - PROTECTION OF WORK AND OF PERSONS AND PROPERTY
SC-107.19.2.1
Add the following new Item 107.19.2.1 immediately after Item 107.19.2:
“107.19.2.1 Should CONTRACTOR cause damage to the work or property of
any separate contractor at the site, or should any claim arise out of
CONTRACTOR's, OWNER’s, ENGINEER’s, Consulting Engineer’s
or any other person’s actions, CONTRACTOR shall promptly attempt
to settle with such other contractor by agreement, or to otherwise

resolve the dispute by arbitration or at law. CONTRACTOR shall, to
the fullest extent permitted by Laws and Regulations, indemnify and
hold OWNER, ENGINEER and Consulting Engineer harmless from
and against all claims, damages, losses and expenses (including,
but not limited to, fees of engineers, architects, attorneys and other
professionals and court and arbitration costs) arising directly,
indirectly or consequentially out of any action, legal or equitable,
brought by any separate contractor against OWNER, ENGINEER or
Consulting Engineer to the extent based on a claim arising out of
CONTRACTOR'S performance of the Work. Should a separate
contractor cause damage to the work or property of CONTRACTOR
or should the performance of work by any separate contractor at the
site give rise to any other claim, CONTRACTOR shall not institute
any action, legal or equitable, against OWNER, ENGINEER or
Consulting Engineer or permit any action against any of them to be
maintained and continued in its name or for its benefit in any court or
before any arbiter which seeks to impose liability on or to recover
damages from OWNER, ENGINEER or Consulting Engineer on
account of any such damage or claim. If CONTRACTOR is delayed
at any time in performing or furnishing Work by any act or neglect of
a separate contractor and OWNER and CONTRACTOR are unable
to agree as to the extent of any adjustment in Contract Time
attributable thereto, CONTRACTOR may make a claim for an
extension of time in accordance with Item 108.8. An extension of the
Contract Time shall be CONTRACTOR's exclusive remedy with
respect to OWNER, ENGINEER and Consulting Engineer for any
delay, disruption, interference or hindrance caused by any separate
contractor.”
ITEM 107.23 – EXISTING STRUCTURES, FACILITIES AND APPURTENANCES
SC-107.23.2.1
Add the following new Item 107.23.2.1 immediately after Item 107.23.2:
“107.23.2.1 Existing Utilities and Sewer Lines: The CONTRACTOR shall be
responsible for the protection of all existing utilities or service lines
crossed or exposed by the construction operations. Where existing
utilities or service lines are cut, broken or damaged, the
CONTRACTOR shall replace the utilities or service lines with the
same type of original construction, or better, at his own cost and
expense. This includes any and all irrigation systems, whether or not
they are identified on the plans. The CONTRACTOR shall
coordinate a time to video existing sprinkling systems with adjacent
property owners to determine if functioning properly in accordance
with the Contract Documents.

If it is necessary to change or move the property of any owner or of a

authorized by the ENGINEER. The right is reserved to the owner of
any public utility to enter upon the limits of the project for the purpose
of making such changes or repairs of their property that may be
made necessary by the performance of this contract.”
ITEM 108.1 – PROGRESS SCHEDULE
SC-108.1
Amend the first sentence of Item 108.1 by adding the following at the beginning of
the sentence: "If requested by OWNER or ENGINEER".
ITEM 108.3 - OTHER CONTRACTORS; OBLIGATION TO COOPERATE
SC-108.3

following in lieu thereof:
"In such event, CONTRACTOR shall be entitled to an extension of working time only
for unavoidable delays verified by the ENGINEER, as provided in Item 108.8;
however, no increase in the contract price shall be due the CONTRACTOR."
Insert the following sentence at the end of the second paragraph of Item 108.3:
"The ENGINEER shall coordinate such other work with the CONTRACTOR and
schedule events to minimize delay caused to the CONTRACTOR. No additional
time shall be given to the CONTRACTOR of such related work except as provided in
Item 108.8."
ITEM 108.8 - DELAYS; EXTENSION OF TIME; LIQUIDATED DAMAGES

the contract time shall be allowed unless the CONTRACTOR can demonstrate the
delay caused an adverse impact to the critical path and that loss of time can not be
made up by revising the sequence of the work of the project."

1.7 EXPLANATION OF CONTRACT TIME:
4-3 Specific Project Requirements
In the event the CONTRACTOR completes the contract prior to the expiration of
the Original Contract Time, the OWNER will pay the CONTRACTOR an incentive
payment of the Daily Value amount specified in Item 20 of the Instructions to
Bidders (Section 1) in the Contract Documents for each calendar day the actual
completion date precedes the Original Contract Time and is subject to the
conditions set forth below. The term “Original Contract Time” as used herein will
mean the number of calendar days established by the CONTRACTOR for
completion of the work of the Contract on the date the Contract was executed.
The term “calendar day” as used in this Article will mean every day shown on the
calendar. Calendar days will be consecutively counted from commencement of
Contract Time regardless of weather, weekends, holidays, suspensions of
CONTRACTOR’s operations, delays or other events as described herein. For
purposes of the calculation and the determination of the incentive/disincentive, the
Original Contract Time will not be adjusted for any reason, cause or circumstance
whatsoever, regardless of fault, save and except in the instance of a catastrophic
event (i.e., war, invasion, riot, declared state of emergency, national strike, or other
situations as declared by the OWNER). The parties anticipate that delays may be
caused by or arise from any number of events during the course of the Contract,
including, but not limited to, work performed, disruptions, permitting issues, actions
of suppliers, subcontractors or other contractors, actions by third parties, weather,
weekends, holidays, or other such events, forces or factors sometimes
experienced in roadway construction work. Such delays or events and their
potential impacts on performance by the CONTRACTOR are specifically
contemplated and acknowledged by the parties in entering into this Contract.
Further, any and all costs or impacts whatsoever incurred by the CONTRACTOR
in accelerating the CONTRACTOR’s work to overcome or absorb such delays or
events in an effort to complete the Contract prior to expiration of the Original
Contract Time, regardless of whether the CONTRACTOR successfully does so or
not, shall be the sole responsibility of the CONTRACTOR in every instance. In the
event the project is altered by work deleted, change orders, supplemental
agreements, utility conflicts, design changes or defects, extra work, right of way
issues, or other situations which are not the fault of or a direct result of
CONTRACTOR negligence which may impact the critical path of the project
construction schedule, the OWNER may choose to negotiate the extension or
reduction of the Original Contract Time with the CONTRACTOR.
In the event of a catastrophic event (i.e., war, invasion, riot, declared state of
emergency, national strike, or other situations as declared by the OWNER) directly
and substantially affecting the CONTRACTOR’s operations on the Contract, the
CONTRACTOR and the OWNER shall agree as to the number of calendar days to
extend the Original Contract Time, so that such extended Original Contract Time
will be used in the calculation of any incentive payment. In the event the
CONTRACTOR and OWNER are unable to agree to the number of calendar days
to extend the Original Contract Time, the OWNER shall unilaterally determine the
number of calendar days to extend the Original contract Time reasonably and
necessary and due solely to such catastrophic event and the CONTRACTOR shall
have no right whatsoever to contest such determination, save and except that the
CONTRACTOR establishes that the number of calendar days determined by the
OWNER were arbitrary or without any reasonable basis. The CONTRACTOR
4-4 Specific Project Requirements
shall have no rights under the Contract to make any claim arising out of this
incentive payment provision except as is expressly set forth in this Provision. As
conditions precedent to the CONTRACTOR’s entitlement to any incentive the
CONTRACTOR must:
1. Actually complete all Contract requirements, including the completion of all
punch list work, and obtain final acceptance by the OWNER prior to expiration
of the Original Contract Time.
2. The CONTRACTOR shall notify the OWNER in writing, within 30 days after the
final acceptance of the Contract by the OWNER, that the CONTRACTOR
elects to be paid the incentive payment which the CONTRACTOR is eligible to
be paid based on the actual final acceptance date, and such written notice
shall constitute a full and complete waiver, release and acknowledgement of
satisfaction by the CONTRACTOR of any and all claims, causes of action,
issues, demands, disputes, matters or controversies, of any nature or kind
whatsoever, known or unknown, against the OWNER, its employees, officers,
agents, representatives, consultants, and their respective employees, officers
and representatives, the CONTRACTOR has or may have, including, but not
limited to, work performed, work deleted, change orders, supplemental
agreements, delays, disruptions, differing site conditions, utility conflicts, design
changes or defects, time extensions, extra work, right of way issues, permitting
issues, actions of suppliers or subcontractors or other contractors, actions by
third parties, shop drawing approval process delays, expansion of the physical
limits of the project to make it functional, weather, weekends, holidays,
suspensions of CONTRACTOR’s operations, extended or unabsorbed home
office or job site overhead, lump sum maintenance of traffic adjustments, lost
profits, prime mark-up on subcontractor work, acceleration costs, any and all
direct and indirect costs, any other adverse impacts, events, conditions,
circumstances or potential damages, on or pertaining to, or as to or arising out
of the Contract. This waiver, release and acknowledgement of satisfaction
shall be all-inclusive and absolute, save and except any routine OWNER final
estimating quantity adjustments.
Should the CONTRACTOR fail to actually complete the Contract and obtain final
acceptance by the OWNER prior to expiration of the Original Contract Time, or
should the CONTRACTOR, having timely completed the Contract and obtained
final acceptance by the OWNER prior to expiration of the Original Contract Time,
but having failed to timely request the incentive payment for any reason, and
including but not limited to the CONTRACTOR choosing not to fully waive, release
and acknowledge satisfaction as set forth in (2) above, the CONTRACTOR shall
have no right to any payment whatsoever under this Article. Notwithstanding the
CONTRACTOR’s election or non-election of the incentive under this provision, the
disincentive provision applies to all circumstances where the work in the Contract
is not finally accepted by the Original Contract Time.
Should the CONTRACTOR fail to complete the Contract on or before the
expiration of the Original Contract Time, as adjusted in accordance with the
provisions above, the OWNER shall deduct from the monies due the
CONTRACTOR the Daily Value specified in the Contract Documents for each
4-5 Specific Project Requirements
calendar day completion exceeds the Original Contract Time. This deduction shall
be the disincentive for the CONTRACTOR’s failing to timely complete the
Contract. This shall be strictly enforced.
In the event the CONTRACTOR elects to exercise this incentive payment
provision, should this provision conflict with any other provision of the Contract; the
Contract shall be interpreted in accordance with this provision. Any reference to
“Substantially Complete” shall be interpreted to be complete with the Contract with

1.0 PURPOSE AND SCOPE
The purpose of this geotechnical exploration is for ALPHA TESTING, INC. (“ALPHA”) to
evaluate for the “Client” some of the physical and engineering properties of subsurface materials
at selected locations on the subject site with respect to formulation of appropriate geotechnical
design parameters for construction services. The field exploration was accomplished by
securing subsurface samples from widely spaced test borings performed across the expanse of
the site. Engineering analyses were performed from results of the field exploration and results of
laboratory tests performed on representative samples.
Also included are general comments pertaining to reasonably anticipated construction problems
and recommendations concerning earthwork and quality control testing during construction.
This information can be used to evaluate subsurface conditions and to aid in ascertaining
construction meets project specifications.
Recommendations provided in this report were developed from information obtained in test
borings depicting subsurface conditions only at the specific boring locations and at the particular
time designated on the logs. Subsurface conditions at other locations may differ from those
observed at the boring locations, and subsurface conditions at boring locations may vary at
different times of the year. The scope of work may not fully define the variability of subsurface
materials and conditions that are present on the site.
The nature and extent of variations between borings may not become evident until construction.
If significant variations then appear evident, our office should be contacted to re-evaluate our
recommendations after performing on-site observations and possibly other tests.
2.0 PROJECT CHARACTERISTICS
It is proposed to construct a new screen wall at the City of Coppell Reservoir site located south
of Village Parkway in Coppell, Texas. At the time the field exploration was performed, an
existing water reservoir facility occupied the site. A site plan illustrating the general outline of
the property is provided as Figure 1, the Boring Location Plan, in the Appendix of this report.
Present plans provide for the construction of a new screen wall. The new screen wall
(masonry/brick wall) is planned to be about 8 ft high with a total length of about 1,200 ft. The
screen wall is planned to extend around most of the site perimeter, except at the front of the site.
The wrought iron fence at the front of the facility will remain in place. It is anticipated the
screen wall will create light to moderate loads and will be supported with a relatively deep
foundation system.
3.0 FIELD EXPLORATION
Subsurface conditions on the site were explored by drilling a total of six (6) test borings to a
depth of about 25 ft each in general accordance with ASTM D 420 using standard rotary drilling
equipment. The approximate location of each test boring is shown on the Boring Location Plan,
Figure 1, enclosed in the Appendix of this report. Details of drilling and sampling operations are
briefly summarized in Methods of Field Exploration, Section A-1 of the Appendix.
ALPHA Report No. G162837

Subsurface types encountered during the field exploration are presented on Log of Boring sheets
included in the Appendix of this report. The boring logs contain our Field Technician's and
Engineer's interpretation of conditions believed to exist between actual samples retrieved.
Therefore, these boring logs contain both factual and interpretive information. Lines delineating
subsurface strata on the boring logs are approximate and the actual transition between strata may
be gradual.
4.0 LABORATORY TESTS
Selected samples of the subsurface materials were tested in the laboratory to evaluate their
engineering properties as a basis in providing recommendations for foundation design and
earthwork construction. A brief description of testing procedures used in the laboratory can be
found in Methods of Laboratory Testing, Section B-1 of the Appendix. Individual test results
are presented either on Log of Boring sheets or on summary data sheets also enclosed in the
Appendix.
5.0 GENERAL SUBSURFACE CONDITIONS
Based on the Geological Atlas of Texas (Dallas Sheet) from the Texas Bureau of Economic
Geology, published by the University of Texas at Austin, the project site is generally located
within alluvium deposits associated with the Trinity River system, overlying the Eagle Ford
Formation. Alluvium deposits consist of predominantly gravel, sand, silt and silty clay from
over bank flow from ancient stream channels. The Eagle Ford Formation is composed
predominantly of shale with occasional platy beds of sandstone and limestone. Residual
overburden soils associated with the Eagle Ford Formation generally consist of clay and shaly
clay with very high shrink/swell potential.
Within the 25-ft maximum depth explored on the site, subsurface materials consist generally
of sandy clay fill, clay/sandy clay, silty sand/sand and deeper shale. The sandy clay fill at the
borings extended to depths of 6 ft to 12 ft below existing grade. Clays were encountered below
the fill, except at Boring 2, and extended to a depth of 12 ft at Boring 1, to a depth of 13 ft at
Borings 4 and 5 and to the termination depth of 25 ft at Borings 3 and 6. Sandy clays were
encountered below the fill at Boring 2 and below the clays at Borings 4 and 5 and extended to
depths of 18 ft and 20 ft. Silty sands and sands were encountered below the clays and sandy
clays at Borings 1, 2 and 4 and extended to depths of 21 ft and 23 ft. Deeper gray shale was
encountered below the silty sands and sands in Borings 1, 2 and 4 at depths of 11 ft to 13 ft and
below the sandy clay in Boring 5 at a depth of 20 ft and extended to boring termination at a
depth of 25 ft.
The silty sand and sand encountered at this site are relatively permeable and expected to have a
relatively rapid response to water movement. However, the clays, sandy clays and shale are
considered relatively impermeable and are anticipated to have a slower response to water
movement. Therefore, due to the presence of the relatively impermeable soils, several days of
observation will be required to evaluate actual groundwater levels within the depths explored.
Also, the groundwater level at the site is anticipated to fluctuate seasonally depending on the
amount of rainfall, prevailing weather conditions and subsurface drainage characteristics.
ALPHA Report No. G162837
3
During field explorations, free groundwater was noted on drilling tools and in open boreholes
upon completion at depths of about 9 ft to 22 ft below the existing ground surface at Borings 1
through 5. Groundwater was not encountered at Boring 6. However, it is common to detect
shallow seasonal groundwater from within fill soils, natural fractures within the clayey matrix, in
the granular soils, near the soil/rock (gray shale) interface or from fractures in the rock,
particularly during or after periods of precipitation. If more detailed groundwater information is
required, monitoring wells or piezometers can be installed. Additionally, bore hole cave-in
occurred at depths of about 18 ft to 22 ft upon completion in Borings 1, 2 and 4.
Further details concerning subsurface materials and conditions encountered can be obtained from
the Log of Boring sheets provided in the Appendix of this report.
6.0 DESIGN RECOMMENDATIONS
The following design recommendations were developed on the basis of the previously described
Project Characteristics (Section 2.0) and General Subsurface Conditions (Section 5.0). If project
criteria should change our office should conduct a review to determine if modifications to the
recommendations are required. Further, it is recommended our office be provided with a copy of
the final plans and specifications for review prior to construction.
6.1 Potential Seasonal Movements
Our findings from the borings indicate soil-related potential seasonal movements are up
to about 3 inches for construction within 2 ft of existing grade. The above potential
seasonal movements were estimated using results of absorption swell tests, in general
accordance with methods outlined by TxDOT Test Method Tex-124-E and engineering
judgment and experience. Estimated movements were calculated assuming the moisture
content of the in-situ soil within the normal zone of seasonal moisture content change
varies between a "dry" condition and a "wet" condition as defined by Tex-124-E. Also, it
was assumed a 1 psi surcharge load from the slab acts on the subgrade soils. Movements
exceeding those predicted above could occur if positive drainage of surface water is not
maintained or if soils are subject to an outside water source, such as leakage from a
utility line or subsurface moisture migration from off-site locations.
6.2 Helical Piers
Due to the variable nature of the subsurface materials consisting of clays, sandy clays,
silty sands and sands, and relatively high free groundwater levels encountered at the
borings, helical pier foundations could be considered for the screen wall. Helical piers
should bear in native clay/sandy clay/silty sand/sand at a minimum depth of 15 ft below
existing or final grade, whichever is deeper. Helical piers are a manufactured foundation
element consisting of a centralized steel shaft and one or more helical bearing plates at
the bottom of the shaft.
The helical plates are formed with a uniform-pitch screw thread, and the pier is installed
by rotating it into the ground to the desired depth or refusal. The helical plate(s) provides
end bearing resistance due to gravity loads and uplift resistance due to swelling of high
shrink-swell active clays such as encountered at the boring locations.
ALPHA Report No. G162837

There are generally two modes of helical pier behavior; individual helix and group helix.
In the case of individual helix, each helix acts independently of the other and the total
helical pier capacity is based on the sum of the bearing capacities of the individual
helixes. In the case of group helix, the total helical pier capacity is based on the bearing
capacity of the bottom helix and skin friction developed from a cylinder of soil developed
between the helixes. Independent helix capacity occurs when helixes are widely spaced
(about 3 or more helix diameters apart) and group helix capacity occurs when helixes are
spaced closely together (less than 3 helix diameters).
For helical piers bearing in clay/sandy clay/silty sand/sand soils at a minimum depth of
15 ft below existing or final grade, whichever is deeper, exhibiting independent helix
behavior, pier capacity can be calculated by summing the allowable end bearing
pressures of 3 kips per sq ft applied to the lowermost helix and a reduced bearing
capacity of 1.5 kips per sq ft applied to any overlying helixes. For helical piers,
exhibiting group helix behavior, pier capacity can be calculated by summing the
allowable bearing pressure of 1.5 kips per sq ft applied to the lowermost helix with an
allowable skin friction of 0.8 kips per square foot taken over the surface of the soil
cylinder developed between the lowermost helix and any overlying helixes.
The minimum helix diameter must be sized to prevent the bearing soils from being over-
stressed and to develop sufficient uplift capacity to overcome the potential uplift forces
acting on the pier. The helix portion should be at least three (3) times the width of the
shaft. The minimum clear spacing between edges of adjacent piers should be at least two
(2) helix diameters (based on the larger helix). Normal elastic settlement of helical piers
under loading is estimated at less than about 1 inch.
Each helical pier should be designed to resist the uplift pressure (soil-to-pier adhesion)
due to potential soil swell along the shaft from post construction heave and other uplift
forces applied by structural loadings. The magnitude of uplift adhesion due to soil swell
along the helical pier shaft cannot be defined accurately and can vary according to the
actual in-place moisture content of the soils during construction. It is estimated this
uplift adhesion will be about 1.6 kips per sq ft to a depth of about 12 ft below the ground
surface.
From our experience, helical piers are frequently designed and installed by specialty
contractors with capacities in excess of those calculated by conventional static analysis.
Helical piers should be designed by a professional engineer and should be installed per
the manufacturer’s requirements. Helical piers should be load tested to verify the pier is
capable of supporting the design load. Load tests can also be utilized to maximize the
foundation load, thereby reducing the number of piers. We recommend performing at
least one helical pier load test. ALPHA TESTING would be pleased to assist in design,
implementation, and evaluation of a pier load test if desired.
All grade beams connecting piers and pier caps should be formed and not cast in earthen
trenches. Grade beams/pier caps should be formed with a nominal 6-inch void at the
bottom. Commercially available cardboard box forms (cartons) are made for this
purpose. The cardboard cartons should extend the full length and width of the grade
beams/pier caps. Prior to concrete placement, the cartons should be inspected to verify
ALPHA Report No. G162837

they are firm, properly placed, and capable of supporting wet concrete. Some type of
permanent soil retainer, such as pre-cast concrete panels, must be provided to prevent
soils adjacent to grade beams/pier caps from sloughing into the void space at the bottom
of the grade beams. Additionally, backfill soils placed adjacent to grade beams must be
compacted as outlined in Section 7.2 of this report.
Please note: Existing uncontrolled fill was encountered to depths of about 6 ft to 12
ft below existing grade at the test borings. Deeper uncontrolled fill may be present
at some areas of the site. Varying amounts of limestone/shale fragments and gravel
were encountered in the uncontrolled fill. Although not encountered at the borings,
uncontrolled fill can contain concrete, rubble, and other debris that could cause
obstruction to pier installation. The pier drilling contract should contain provision
for penetration or removal of obstructions.
6.3 Seismic Considerations
The Site Class for seismic design is based on several factors that include soil profile
(soil or rock), shear wave velocity, and strength, averaged over a depth of 100 ft.
Since our borings did not extend to 100-foot depths, we based our determinations on
the assumption that the subsurface materials below the bottom of the borings
were similar to those encountered at the termination depth of the borings. Based on
Section 1613.3.2 of the 2012 International Building Code and Table 20.3-1 in the
2010 ASCE-7, we recommend using Site Class D (stiff soil profile) for seismic design at
this site.
6.4 Drainage
Adequate drainage should be provided to reduce seasonal variations in the moisture
content of foundation soils. Final grades within 10 ft of the screen wall should be
adjusted to slope away at a minimum slope of 1 percent.
7.0 GENERAL CONSTRUCTION PROCEDURES AND RECOMMENDATIONS
Variations in subsurface conditions could be encountered during construction. To permit
correlation between test boring data and actual subsurface conditions encountered during
construction, it is recommended a registered Professional Engineering firm be retained to
observe construction procedures and materials.
Some construction problems, particularly degree or magnitude, cannot be anticipated until
the course of construction. The recommendations offered in the following paragraphs are
intended not to limit or preclude other conceivable solutions, but rather to provide our
observations based on our experience and understanding of the project characteristics and
subsurface conditions encountered in the borings.
ALPHA Report No. G162837

Construction site safety is the sole responsibility of the contractor, who shall also be solely
responsible for the means, methods and sequencing of construction operations. The contractor
should also be aware that slope height, slope inclination or excavation depths (including utility
trench excavations) should in no case exceed those specified in local, state and/or federal safety
regulations, such as OSHA Health and Safety Standard for Excavations, 29 CFR Part 1926, or
successor regulations. Stockpiles should be placed well away from the edge of the excavation
and their heights should be controlled so they do not surcharge the sides of the excavation.
Surface drainage should be carefully controlled to prevent flow of water over the slopes and/or
into the excavations. Construction slopes should be closely observed for signs of mass
movement, including tension cracks near the crest or bulging at the toe. If potential stability
problems are observed, a geotechnical engineer should be contacted immediately. Shoring,
bracing or underpinning required for the project (if any) should be designed by a professional
engineer registered in the State of Texas.
Due to the nature of the clayey soils found near the surface of the borings, traffic of heavy
equipment (including heavy compaction equipment) may create pumping and general
deterioration of shallow soils. Therefore, some construction difficulties should be anticipated
during periods when these soils are saturated.
Uncontrolled fill material was encountered to depths of about 6 ft to 12 ft below the existing
ground surface at the borings. From our experience, uncontrolled fills can contain boulders,
concrete, general debris, and other unsuitable materials, especially in an urban environment.
Excavation and grading contracts should contain provision for removal of unsuitable materials
from existing fill.
7.1 Fill Compaction
Sandy clays with a plasticity index below 25 should be compacted to a dry density of at
least 95 percent of standard Proctor maximum dry density (ASTM D 698) and within the
range of 1 percentage point below to 3 percentage points above the material's optimum
moisture content.
Clay soils with a plasticity index equal to or greater than 25 should be compacted to a dry
density between 93 and 98 percent of standard Proctor maximum dry density (ASTM
D 698). The compacted moisture content of the clays during placement should be within
the range of 2 to 6 percentage points above optimum.
Clayey materials used as fill should be processed and the largest particle or clod should
be less than 6 inches prior to compaction.
Silty sands and sands should be compacted to a dry density between 95 and 100 percent
of standard Proctor maximum dry density (ASTM D 698). The compacted moisture
content of the clays during placement should be within the range of 0 to 4 percentage
points above optimum.
ALPHA Report No. G162837
7
In cases where either mass fills or utility lines are more than 10 ft deep, the fill/backfill
below 10 ft should be compacted to at least 98 percent of standard Proctor maximum dry
density (ASTM D-698) and within 2 percentage points of the material's optimum
moisture content. The portion of the fill/backfill shallower than 10 ft should be
compacted as outlined above.
Even if fill is properly compacted, fills in excess of about 10 ft are still subject to
settlements over time of up to about 1 to 2 percent of the total fill thickness.
Compaction should be accomplished by placing fill in about 8-inch thick loose lifts
and compacting each lift to at least the specified minimum dry density. Field density
and moisture content tests should be performed on each lift.
7.2 Groundwater
Groundwater was encountered at depths of 9 ft to 22 ft at most of the borings. From our
experience with similar soils, shallow groundwater seepage could be encountered in
excavations for grade beams, foundations, utility conduits and other general excavations.
The risk of encountering seepage increases with depth of excavation and during or after
periods of precipitation. Standard sump pits and pumping may be adequate to control
minor seepage on a local basis for relatively shallow excavations and those that do not
encounter silty sand/sand. Supplemental dewatering measures such as (but not limited
to) submersible pumps in slotted casings and wellpoints may be required for deeper
excavations and/or where sands are encountered.

APPENDIX
ALPHA Report No. G162837
A-1 METHODS OF FIELD EXPLORATION
Using standard rotary drilling equipment, a total of six (6) test borings were performed for this
geotechnical exploration at the approximate locations shown on the Boring Location Plan,
Figure 1. The test boring locations were staked by either pacing or taping and estimating right
angles from landmarks which could be identified in the field and as shown on the site plan
provided during this study. The locations of test borings shown on the Boring Location Plan are
considered accurate only to the degree implied by the method used to locate the borings.
Relatively undisturbed samples of the cohesive subsurface materials were obtained by
hydraulically pressing 3-inch O.D. thin-wall sampling tubes into the underlying soils at selected
depths (ASTM D 1587). These samples were removed from the sampling tubes in the field and
examined visually. One representative portion of each sample was sealed in a plastic bag for use
in future visual examinations and possible testing in the laboratory.
In addition, representative samples of granular materials were obtained employing split-spoon
sampling procedures in general accordance with ASTM Standard D 1586. Disturbed samples
were obtained at selected depths in the borings by driving a standard 2-inch O.D. split-spoon
sampler 18 inches into the subsurface material using a 170-pound hammer falling 24 inches.
The number of blows required to drive the split-spoon sampler the final 12 inches of penetration
(N-value) is recorded in the appropriate column on the Log of Boring sheets.
The Texas Cone Penetration (TCP) test was used to assess the apparent in-place strength
characteristics of the rock type materials. The TCP test consists of a 3-inch diameter steel cone
driven by a 170-pound hammer dropped 24 inches (340 ft-pounds of energy) and is the basis for
TxDOT strength correlations. Depending on the resistance (strength) of the materials, either the
number of blows of the hammer required to provide 12 inches of penetration, or the inches of
penetration of the cone due to 100 blows of the hammer are recorded on the field logs and
are shown on the Log of Boring sheets as “TX Cone” (reference: TxDOT Test Method
TEX 132-E).
Logs of all borings are included in the Appendix of this report. The logs show visual
descriptions of subsurface strata encountered using the Unified Soil Classification System.
Sampling information, pertinent field data, and field observations are also included. Samples not
consumed by testing will be retained in our laboratory for at least 14 days and then discarded
unless the Client requests otherwise.
ALPHA Report No. G162837
B-1 METHODS OF LABORATORY TESTING
Representative samples were examined and classified by a qualified member of the Geotechnical
Division and the boring logs were edited as necessary. To aid in classifying the subsurface
materials and to determine the general engineering characteristics, natural moisture content tests
(ASTM D 2216), Atterberg-limit tests (ASTM D 4318), percent material passing the No. 200
sieve (ASTM D1140) and dry unit weight determinations were performed on selected samples.
In addition, unconfined compression (ASTM D 2166) and pocket-penetrometer tests were
conducted on selected soil samples to evaluate the soil shear strength. Results of all laboratory
tests described above are provided on the accompanying Log of Boring sheets.
In addition to the Atterberg-limit tests, the expansive properties of the clay soils were further
analyzed by absorption swell tests. The swell test is performed by placing a selected sample in a
consolidation machine and applying either the approximate current or expected overburden
pressure and then allowing the sample to absorb water. When the sample exhibits very little
tendency for further expansion, the height increase is recorded and the percent free swell and
total moisture gain calculated. Results of the absorption swell test are provided on the Swell
Test Data sheet, Figure 2 included in this appendix.
