Conveying Concrete:
Convey concrete from the mixer to the place of final
deposit by methods which will prevent the separation of the
ingredients.
Ce
Depositing Concrete:
General: Place concrete in reasonable uniform layers,
approximately horizontal, and not more than 12 inches deep,
exercising care to avoid vertical joints or inclined
planes. The piling up of concrete in forms, in such a
manner as to cause the separation or loss of any of its
ingredients, will not be permitted. Concrete which has
partially set or hardened shall not, under any
circumstances, be deposited in the work. Place concrete in
the forms as nearly in its final position as is practical
to avoid rehandling. Exercise special care to prevent
splashing the forms or reinforcement before the work
proceeds. Do' not place concrete on previously deposited
concrete which has hardened sufficiently to cause the
formation of seams or planes of weakness within the
respective member or section, except as hereinafter
specified. Do not permit concrete to drop freely at
distance greater than 3 feet. Where longer drops are
necessary use a chute, tremie, or other approved conveyance
to assist the concrete into place without separation. Do
not pour directly into any excavation where water is
standing. If the place of deposit cannot be successfully
pumped dry, pour through a tremie with its outlet end near
the bottom of the place of deposit.
e
Slump: Concrete shall not be placed when its plasticity,
as measured by slump tests, is outside the limits
determined by the independent testing laboratory.
e
Vibration: As soon as concrete is deposited, thoroughly
agitate the same by means of mechanical vibrators and
suitable hand tools, so manipulated as to work the mixture
well into all parts and corners of the forms, and entirely

Geotechnical Investigation
Proposed Brick Wa]is
Lakes of Coppell, MacArthur
and Parkway Boulevards
Coppdl, Texas
Dear Mro Cobb:
In accordance with your request, we have performed a geotechnical
investigation at the above referenced site. The purpose of this
investigation was to provide design recommendations for free standing
wa]is along MacArthur and Parkway Boulevards. No additional analyses
were requested or performed.
This report is being submitted in summary form. Descriptions and
details of the various field and laboratory tests are on file in our
office and may be obtained upon request. The results of the field and
laboratory tests are shown on the individual boring logs submitted
herewith.
SUMMARY:
The project site is located in the City of Coppell within the Lakes
of Coppell Development, Current plans indicate that brick walls
will be constructed along the north and the south sides of MacArthur
and Parkway Boulevards at the locations indicated on the enclosed
Plan.
e
The generalized subsurface profile revealed by the test borings
consisted of gray, brown, reddish brown and yellowish brown days,
sandy clays, clayey sands and sands. The primary gray shale stratum

was encountered at depths ranging between 1.0 and 11.0 feet below
the existing ground surface except in test borings B-1 and B-2 where
the shale was not encountered during the drilling operations.
Seepage water was encountered in test borings B-6, B-7 and B-12 at
5.0, 7.0 and 7.0 feet below the existing ground surface, respec-
tively. However this condition may change with seasonal climatic
conditions and should be verified prior to construction.
The structural loads of the proposed wall may be supported by one of
the following foundation systems:
Auger excavated, cast-in-place, straight shaft reinforced con-
crete piers founded at least two feet into the primary gray
shale layer if the shale is encountered at a depth of less than
12 feet below the existing ground surface. The piers may be
designed using an allowable bearing pressure of 10,000 pounds
per square foot.
In areas where the shale is not encountered within the top 12
feet (area of borings B-1 and B-2), the piers may be underreamed
twalve (12) feet below the ground surface. An allowable end
bearing pressure of 2,400 pounds per square foot may be used.
The pier shafts should contain enough steel reinforcement to
resist tension forces of up to 1,000 pounds per square foot
acting in a vertical direction that may be created by the swel-
ling of the surficial overburden softs. Foundation piers,
proportioned, designed and placed in accordance with the recom-
mendations provided in this report will have a factor of safety
in excess of 2.0 against shear type failure. Differential
settlement between adjacent piers should be less than 0.5 of an
inch; or
Individual or continuous footings founded approximately two (2)
feet below the ground surface within the clay, sandy clay,
clayey sand and sand softs and designed using an allowable soft
bearing pressure of 2,300 pounds per square foot. Care should
be taken to insure that the footings excavations are free of
loose material prior to the placement of the concrete.
The walls or grade beams should be designed to withstand differen-
tial vertical soft movement of up to 2.00 inches caused by the swel-
ling of the near surface softs, or should be provided with a void
space between the exposed subgrade soils and the wall/grade beam
structure where foundation piers are used.
