PART 4 TECHNICAL PROVISIONS
SECTION 1 - EARTHWORK
A. Sc . The work shall include excavation, trenching and back-
filling required for construction of the pump station and appurtenant
piping, complete.
B. Excavation.
(1) General. All excavation of every description and of whatever
substances encountereZ shall be performed to the depths indicated or as
otherwise specified. During excavations, material suitable for backfilling
shall;be piled in an orderly manner a sufficient distance from the banks
of the trench to avoid overloading and to prevent slides or cave-ins. All
excavated materials not required or suitable for backfill shall be removed
and wasted as indicated or as directed. Grading shall be done as may be
necessary to prevent surface water from flowing into trenches or other
excavations, and any water accumulating therein shall be removed by
pumping or by othere approved methods. Sheeting and shoring shall be
done ao may be necessary for the protection of the work and for the safety
of personnel. Unless otherwise indicated, excavation shall be by open cut
except that short sections of a trench may, be tunneled if, in the opinion of
the Engineer, the pipe can be safely and properly installed and backfill can
be properly tamped in such tunnel sections.
(2) Excavation for gump pit, manholes and similar structures
shall be sufficient to leave a clear space between the outer surfaces and the
embankment or timber that may be used to hold and protect the banks. Any
overdepth excavation below such appurtenances that has not been directed
by the Engineer will be considered unauthorized and shall be refilled with
sand, gravel, or concrete, as directed, at no additional cost.
(3) Trench Excavation. Trenches shall be of the necessary
width for proper laying o t e pipe with width at and below the elevation
of the top of pipe not exceeding 8 inches on either side. The width of the
trench above that level shall be as wide as necessary for sheeting, bracing,
and the proper performance of the work. The trench shall be excavated to
a depth of six inches below the pipe invert for the full trench width and the
overexcavated space filled with crushed rock or gravel for the gravity sewers
and sand for the sewer force mains. The pipe bedding material shall be
compacted and then shaped to fit the lower portion of the pipe wall as
indicated on the drawings. The pipe shall bear uniformly on the trench
bottom except at joints and belly depressions which shall be excavated to
avoid bearing of the couplings or bells.
(a) Crusher 'Run Rock and Gravel. Crusher run rock or
gravel shall be natural, sound stone with the o owing gradation by weight
1 -1 "
passing a standard Tyler square mesh screen:
Screen Size Percent Passing
1 -1/2 inch 100
1 inch 90-100
3/4 inch 50-80
4 mesh 10-30
30 mesh 0-15
The material shall show a loss weight of not to exceed
50 percent when subjected to the Los Angeles rattler test in accordance
with ASTM-C-131 -55.
(b) Sand. Sand shall be any, free draining, durable
silicilous, granitic, or igeneous material with not more than b percent
passing a 200 mesh screen.
(4) Protection of Utility Lines. Existing underground
construction has een locatedroan a vailable data and spot checked by
excavations and is considered to be reasonably accurate. The Contractor
shall be responsible for protecting all existing underground installations
not indicated as abandoned, whether shown or not, from damage caused
by his operations including excavation and backfilling and shall repair to
the satisfaction of the Owner any installations damaged at no additional
cost to the Owner. Any modifications or relocations of existing buried
installations indicated in the wrong locations or not shown shall be cause
for additional compensation to the Contractor for the actual direct cost of
the additional work. Any relocations of the new construction required
herein caused by underground installations not properly located br not
shown shall be cause for additional compensation to be paid, at actual
direct cost, to the Contractor, if additional work or re-work is ordered
by the Engineer,
C. Backfilling.
(1) General. Joints of ventilation lines, sewer lines and sewer
force mains shall not be backfilled until all required tests are performed
and until the systems as installed conform to the requirements specified.
There, in the opinion of the Engineer, damage is likely to result from
withdrawing sheeting, the sheeting shall be left in place. Except as other-
wise specified for special conditions of overdepths, trenches shall be
backfilled to the ground surface with selected excavated material or other
material that is suitable for the specified compaction and as hereinafter
specified. Trenches improperly backfilled shall be reopened to the depth
required for proper compaction, then refilled and compacted as specified,
or the condition shall be otherwise corrected as permitted by the Engineer.
(24 Structures shall not be backfilled until the concrete or
rnpxtar has attaine its design strength, unless otherwise authorized by
the Engineer. Selected backfill from excavated material or imported sand
or gravel shall be placed to a density specified below. Backfilling operations
1 -2
shall be carried on simultaneously around the structures so as to prevent
eccentric loadings. Approved ;hand powered tampers shall be used to
obtain the specified density in the restricted areas adjacent to structures. _
(3) Lower Portion of the Trench. The lower portion of the
trench to 6 inches above the top of t e pipe shall be backfilled with imported
sand as specified hereinbefore for bedding. The sand material shall be
placed in not to exceed 6 inch layers wetted and compacted carefully around-
and under the pipe haunches by power tampers or hand tampers to 95%
of maximum density. Flooding or jetting will not be permitted. Special .
care shall be taken to avoid damage to pipe coating where applicable.
(4) Remainder of Trench. The remainder of the trench shall
be backfilled with material that is free of stones larger than 6 inches in
any dimension. Backfill material shall be deposited in 6 to 12 inch layers
and compacted to 90 percent of modified AASHO maximum density.
D. Determination of AASHHO Density. Compaction-test specimens
required byte Engineer shall e urnished by the Contractor. A separate
batch of soil shall be furnished for each compaction-test specimen. No
materials will be reused. Tests will be performed by the Engineer at no
expense to the Contractor. Determination of density will conform with
the requirements of AASHO Standard T 147-54 in the field, and the moisture-
density relations will be determined in the laboratory in accordance with
AASHO Standard T 100-57, Method D, modified as follows:
(1) The mold will be 7-inches high. A metal spacer disk,
5-15/16 inches in diameter and 2-1 /Z inches high will be used as a false
bottom in the mold during compaction and the correction factor will be
adjusted accordingly.
(2) Material over 3/4-inch in size will be removed and replaced
with an equal portion of material of a size retained on a No. 4 sieve, but
nothing more than 3/4-inch in size.
(3) ,The desired amount of water will be added to each compaction-
test specimen, mixed well, and the specimen placed in a container with an
airtight cover and allowed to cure for 24 hours. A shorter curing time may
be used where tests show that shortening the curing time will not affecte
the results. The water content should be redetermined after the curing
period if appreciable condensation occurs on the wall of the container.
(4) For cohesive materials, the water content will range from
below to above the estimated optimum. For cohesionless materials, the
water content will range from air-dried to as high as practicable.
E. C_l_e_a_n_-U Upon completion of the backfill, and compaction
requirements, tie Contractor shall dispose of all excess excavated materials
and the site shall be left in a clean and orderly condition to the satisfaction
of the Engineer. Excess materials shall be disposed of on the site as
directed.
