section.
1. GENERAL
A. The Contractor shall inspect the site of the work and assume all
responsibility as to the nature of the materials which may be
encountered in the excavation.
B. The Contractor shall make excavations of normal depth in earth for
trenches and structure; shall backfill such excavations to the extent
necessary; shall furnish all plant, labor, equipment and materials
and perform all operations in connection with the stripping,
excavation, filling, dewatering, backfilling, sheeting and bracing,
and rough grading, complete as indicated on the drawings and as
specified herein.
C. Excavation, dewatering, sheeting and bracing shall be carried out so
as to eliminate all possibility of undermining or disturbing the
foundations of existing structures or of work previously completed
under this contract.
• D. The Engineer will establish a bench mark, or marks, and it shall be
the Contractor's responsibility to set all required lines and grades
from those marks.
2. REMOVAL OF SURFACE MATERIALS
A. The Contractor shall remove only as much of any existing pavement as
is necessary for the prosecution of the work. All bituminous
pavement shall be cut to an even edge with pneumatic tools in advance
of the excavation. The Engineer shall also require that the pavement
be cut again with pneumatic tools, without extra compensation to the
Contractor, and where, in the opinion of the Engineer, it is
'necessary to properly prepare the road surface for paving. Where
pavement is removed in large pieces, it shall be disposed of before
proceeding with the excavation.
B. Loam and topsoil shall be removed from areas within which excavations
are to be made, and shall be stored for future use or if the
Contractor prefers not to separate surface materials, he shall
furnish, as directed, loam and topsoil at least equal in quantity and
quality to that excavated.
3. EXTENT OF OPEN EXCAVATION
A. The Contractor shall make excavations in such manner and to such
widths as will give suitable room for building the structures or
laying and jointing the piping; shall furnish and place all sheeting,
bracing, and supports; shall do all cofferdamming, pumping, and
. 222-2
draining; and shall render the bottom of the excavation firm and dry
and acceptable in all respects. Excavation shall extend a sufficient
distance from walls and footings to allow for placing and removal of
forms, installation of services and for inspection, except where
concrete for walls and footings is authorized by the Engineer to be
deposited directly against excavated surfaces. Under-cutting will
not be permitted. In conditions where suitable bearing soils are
encountered at different elevations from those indicated on the
drawings, the Engineer may direct in writing that the excavation be
carried to elevations above or below those indicated on the drawings.
B. After excavation has been made, and before forms set for footings,
slabs, or other structures, and before reinforcing is placed, the
surface to support concrete items shall be compacted with vibratory
roller or compactor in order to consolidate disturbed material.
C. If material unsuitable for foundations (in the opinion of the
Engineer) is found at or below the grade to which excavation would
normally be carried in accordance with the drawings and/or
specifications, the Contractor shall remove such material to the
width and depth ordered by the Engineer and replace it with compacted
bank-run gravel or concrete or other material placed in the dry as
herein specified, or indicated on the drawings and as approved by the
. Engineer.
D. Unless so approved or directed by the Engineer, excavation shall not
be carried below the elevations indicated on the drawings. All
excavations carried outside of the lines and grades given or
specified, together with the disposal of such material and
backfilling of such excavations, shall be at the Contractor's own
expense.
E. If the bottom of any excavation for piping to be installed without a
concrete cradle or encasement is taken beyond the limits indicated or
specified, the resulting void shall be backfilled at the Contractor's
expense with thoroughly compacted bankrun or screened gravel or with
2000 psi concrete, if the excavation was for a concrete structure.
F. If the bottom of any excavation for structures is taken beyond the
limits indicated or specified, the resulting void shall be backfilled
at the Contractor's expense with compacted bank-run gravel or
concrete, placed as hereinafter specified and/or approved by the
Engineer.
G. In no case, except as provided for the Article titled "Trench
Excavation", shall the earth be plowed, scraped, or dug by machinery
so near to the finished subgrade as to result in the disturbance of
material below said subgrade and the last of the material to be
excavated shall be removed with pick and shovel, or approved
equipment such as a smooth toothless bucket just before the placing
of the pipe, masonry, or other structure.
. 222-3
H. All excavations, except as otherwise specified or permitted, shall be
made in the open. The final trimming of the bottoms and sides of
excavations against which concrete is to be placed shall be done just
before the concrete is placed.
4. SHEETING 6 BRACING
A. The Contractor shall furnish, put in place, and maintain such
sheeting, bracing, etc. , as may be necessary to support the sides of
the excavation and to prevent any movement of earth that could in any
way diminish the width of the excavation to less than the necessary
for proper construction, or would otherwise injure or delay the work,
or endanger adjacent structures or workmen. If the Engineer is of
the opinion that at any point, sufficient or proper supports have not
been provided, he may order additional supports put in at the expense
of the Contractor. The Contractor alone is responsible for sheeting
and bracing.
B. Whenever possible, sheeting shall be driven ahead of the excavation
to avoid loss of material from behind the face along which the
sheeting will be driven. Care shall be taken to prevent voids
outside of the sheeting, but, if voids occur, they shall be filled
• immediately with sand and compacted.
C. The Contractor shall leave in place to be embedded in the backfill,
or concrete, all wood sheeting, bracing, etc. He also shall leave in
place any and all other sheeting, bracing, etc. , which the Engineer
may direct him in writing to leave in place, at any time during the
progress of the work, for the purpose of preventing injury to
structures or property.
D. All sheeting and bracing that is not necessary to be left in place
shall be reioved so as not to endanger the construction or other
structures. All voids left or caused by the withdrawal of sheeting
shall be backfilled immediately with approved material and compacted
by ramming with tools especially adapted to that purpose, or by other
means as may be directed. As compensation for all sheeting not left
in place the cost of furnishing, placing, cutting, and removal
thereof is to be included in the price to be paid for under the pipe
installation item. Unless otherwise specified, sheeting to be left
in place shall be cut off and left in place at a line 5'0" below the
top of trench but in no case less than V 0" above the crown of the
pipe.
5. DRAINAGE
A. The Contractor shall provide and maintain ample means and devices
• (including spare units kept ready for immediate use in case of
breakdowns) with which to intercept and/or remove promptly and
dispose of properly all water entering trenches and other
. 222-4
excavations. Such excavations shall be kept dry until the
structures, pipes, and appurtenances to be built therein have been
completed to such extent that they will not float or otherwise be
C
aged.
atering shall be accomplished in a manner that will preserve the
istubed state of the foundation soils. All water pumped or
ined from the work shall be disposed of in a suitable manner
hout undue interference with other work, damage to pavement, other
faces, or property. Suitable temporary pipes, flumes, or channels
ll be provided for water that may flow along or across the site of
work.
C. Care shall be exercised to prevent soil, sand and silt from entering
the existing catchbasins, pipes and ditches of the drainage system
and all deposits formed therein as a result of the Contractor's
operations shall be removed at his expense.
D. Temporary underdrains, if used, shall be laid in trenches beneath the
grade of the structure. Trenches shall be of suitable dimensions to
provide room for the chosen size of underdrain and its surrounding
screened gravel.
• E. Temporary underdrain pipe shall be approved asbestos-cement,
vitrified-clay or concrete pipe of standard thickness. Temporary
underdrains, if used, shall be laid at an approved distance below the
bottom of the normal excavation and with open joints wrapped in
cheesecloth, and entirely surrounded by screened gravel. The
distance between the bottom of the pipe or structure and the top of
the bell of the underdrain pipe shall be at least 3" unless otherwise
permitted. The space between the underdrain and the pipe or
structure shall be filled with sand meeting the requirements of ASTM
Designation C-33 which shall be rammed if necessary and left with a
surface suitable for laying the pipe or building the structure.
Following their use, underdrains shall be plugged as directed by the
Engineer.
6. TRENCH EXCAVATION
A. The Contractor shall make all excavations are required for proper
installation of waterlines and appurtenances, including disposition
of excavated materials as specified herein.

filling and disposal of any and all materials encountered within the
limits of the work, and shall include all pumping, bailing, refill
and protection therefor. Excavation of ledge includes replacement
with satisfactory material.
•
222_5
C. Where pipe is to be laid in crushed stone, gravel bedding or concrete
cradle, the trench may be excavated by machinery to, or just below,
the designated subgrade, provided that the material remaining at the
bottom of the trench is no more than slightly disturbed.
D. Where pipe is to be laid directly on the trench bottom, the lower
part of trenches in earth shall not be excavated to subgrade by
machinery, but, just before the pipe is to be placed, the last of the
material to be excavated shall be removed by means of hand tools to
form a flat or shaped bottom, true to grade, so that the pipe will
have uniform and continuous bearing on firm and undisturbed material
between joints, except where the use of pipe slings may have
disturbed the bottom in limited areas.
7. TRENCH WIDTH
A. Pipe trenches shall be made as narrow as practicable and shall not
have to be widened by scraping or loosening materials from the sides.
Every effort shall be made to keep the sides of the trenches firm and
undisturbed.
B. Trenches shall be excavated with approximately vertical sides between
the elevation of the center of the pipe and an elevation. 1 foot,
above the top of the pipe.
S. TRENCH EXCAVATION IN FILL
A. If the pipe is to be laid in embankments or other recently filled
naterial, the material shall first be placed to the top of the fill
or to a height cf at leaet 1 foot above the top of the p=re,
whichever is the lesser. Particular care sha7.1 re tEVEn to '-cure
maximum consolidation of material under the pipe location. The pipe
trench shall be excavated as though in undisturbed material.
9. EXCAVATION NEAR EXISTING STRUCTURES
A. Items encountered in excavations may include pipe, electric conduit
and other utility services, and may also include lumber, masonry, or
other materials from previous constructions. Some of these have been
indicated on the drawings, but no attempt has been made to show all
such items and the accuracy of the information is not guaranteed.
The Contractor shall make his own investigations to determine the
presence of these utilities or former constructions.
B. As the excavation approaches pipe, conduits, or other underground
structures, digging by machinery shall be discontinued and the
excavation shall be done by means of hand tools, as directed. Such
manual excavation when incidental to normal excavation shall be
• included in the work to be done under items involving normal
excavation.
. 222-6
C. Where the exact location of a pipe or other underground structure is
necessary for doing the work properly, the Contractor may be required
to excavate test pits to determine such locations. When such test
pits may be properly considered as incidental to other excavation,
the Contractor shall receive no additional compensation, the work
being understood to be included as a part of the excavation.
10. * PROTECTION OF EXISTING STRUCTURES
A. All existing walks, pipes, conduits, poles, wires, fences, curbings,
property-line markers, walls, buildings, and other structures which
do not, in the opinion of the Engineer, require to be changed in
location, shall be carefully supported and protected from injury by
the Contractor without additional compensation, and in case of
injury, they shall be restored by him without compensation therefor,
to as good condition as that in which they were found.
11. RELOCATION & REPLACEMENT OF EXISTING STRUCTURES
A. Whenever the Contractor encounters certain existing structures, as
described below, he shall change their location, remove and restore,
replace or assist the Owner in so doing. For all such work the
Contractor shall be paid under such items of work as may be
• applicable.
B. In removing existing pipes or other structures, the Contractor shall
use care to avoid damage to materials, and the Engineer shall include
for payment only those new materials which, in his judgement, are
necessary to replace those unavoidably damaged.
C. The preceding paragraphs apply to pipes, wires, and other structures
which (a) are not indicated on the drawings or otherwise provided
for, (b) encroach upon or are near and substantially parallel to the
edge of an excavation, and (c) in the opinion of the Engineer, will
impede progress to such an extent that satisfactory construction
cannot proceed.
D. -At locations indicated on the plans and detail sheets, or when fences
interfere with the Contractor's operations, he shall remove and
(unless otherwise specified) later restore them to at least as good
condition as that in which they were found immediately before the
work was begun, all without additional compensation. The restoration
of fences shall be done as promptly as possible and not left until
the end of the construction period.
E. The materials removed shall be utilized in the fence reset except,
where necessary, new posts and bases shall be furnished by the
Contractor. Any materials damaged or lost during or subsequent to
removal shall be replaced by the Contractor without additional
compensation.
• 222-7
F. All new materials required shall be equal in quality and design to
the materials in the present fences.

neatly trimmed and covered with an application of grafting wax or
tree healing paint as directed.'
C. Cultivated hedges, shrubs, and plants which might be injured by the
Contractor's operations shall be protected by suitable means or shall
be dug up and temporarily replanted and maintained. After the
construction operations have been substantially completed, they shall
be replanted in their original positions and cared for until growth
is re-established. If cultivated hedges, shrubs, and plants are
injured to such a degree as to affect their growth or appearance,
they shall be replaced by items at least equal to the kind and
quality of the originals.
D. On paved surfaces, the Contractor shall not use or operate tractors,
bulldozers, or other powered equipment the treads or wheels of which .
will cut or otherwise injure the surfaces.
E. All surfaces which have been injured by the Contractor's operations
shall be restored to a condition at least equal to that in which they
were found immediately before work was begun. The restoration of
existing property or structures shall be done as promptly as
practicable and shall not be left until the end of the construction
. period.
• 222-8
13. DISPOSAL OF SURPLUS EXCAVATED MATERIALS
A. Excavated materials shall not be removed from the site of the work or
disposed of by the contractor except as directed or approved.
Surplus excavated materials suitable for backfill shall be used to
backfill normal excavations in rock or to replace other materials
unacceptable for use as backfill; shall be neatly deposited and
graded so as to make or widen fills, flatten side slopes, or fill
depressions; or shall be neatly deposited for other purposes
indicated by the Owner within its jurisdictional limits; all as
directed or approved and without additional compensation.
B. Any excavated materials not required or not suitable for backfilling
shall be removed from the site of the work and deposit in sites as
directed by the Engineer. The Contractor shall perform such work at
his own expense and in a manner approved by the Engineer.
14. DUST CONTROL
A. During the progress of the work, the Contractor shall conduct his
operations and shall sweep and wet down the streets, as necessary, to
minimize the creation and dispersion of dust.
• B. If the Engineer decides that it is necessary to use calcium chloride
for dust control, the Contractor shall furnish and spread the
materials as directed.
(1) Calcium chloride, when used, shall conform to the requirements
of AASHO-M 144, Type I or Type II and ASTM Designation D-98.
The calcium chloride shall be packaged in moisture proof bags or
in airtight drums with the manufacturer, name of product, net
weight, and percentage of calcium chloride guaranteed by the
manufacturer legibly marked on each container.
(2) Calcium chloride failing to meet the requirements of the
aforementioned specifications or that has become caked or sticky
in shipment, may be rejected by the Engineer.
(3) Calcium chloride shall be uniformly applied at the rate of Ili
pounds per square yard or at any other rate as directed by the
Engineer. Application shall be by means of a mechanical
spreader, or other approved methods. The number and frequency
of application shall be determined by the Engineer.
15. MAINTAIN STREETS PASSABLE
A. Streets, roads and private ways in which pipe lines, structures or
other work is being constructed, shall be maintained passable for
vehicles at all times, unless otherwise ordered by the Engineer.
•
. 222-9
B. The Contractor shall, at his own expense, provide suitable and safe
bridges and other crossing-means where required for the accommodation
of travel and to provide access to private property during
construction. He shall remove said structures upon completion of the
work.
16. BACKFILLING - GENERAL
A. In general, and unless other material is indicated on the drawings or
specified, material used for backfilling trenches and around
structures shall be common fill.
B. Where sufficient common fill is not available, borrow shall be used-
and this shall be paid for at the unit price for type of material
required. Said unit price shall include excavation of poor material,
waste of this material and furnishing and placing the borrow as
replacement material.
C. Frozen material shall not be placed in the backfill nor shall
backfill be placed upon frozen material. Previously frozen material
shall be removed or shall be otherwise treated, as required, before
new backfill is placed.
11, BACKFILLING UNDER AND AROUND STRUCTURES
A. Unless otherwise indicated or specified, all fill and backfill under
structures and pavements adjacent to structures shall be compacted
screened gravel.
B. The fill and backfill materials shall be placed in layers not
exceeding 6 in. in thickness. Unless otherwise indicated or
specified, each layer shall be compacted to 95 percent.
C. After completion of footings, walls and other below-grade
construction and prior to backfilling, all forms shall be removed and
the excavation shall be cleaned of all trash and debris. In general,
backfill shall not be placed until all below-grade concrete has
acquired 28-day strength. Backfill shall be placed when ordered by
the Engineer. All excavations shall be free of water during
backfilling operations. Compacted Bank Run Gravel shall be used to
backfill within 3 feet of structures.
Care shall be exercises in placing fill adjacent to piers, walls,
grade beams, footings, and other structures to prevent lateral
movement. Fill on opposite side of such items shall be kept at
approximately the same elevation to prevent an unbalanced earth
pressure, and shoring shall be used as necessary. Foundation walls
and footings will not withstand unbalanced earth or equipment
loadings.
•
• 222-10
D. Backfill shall be placed in horizontal 9" (max.) loose layers with
moisture content such that the required degree of compaction may be
obtained. Each layer shall be compacted with machine tampers or
other suitable mechanical equipment to the density specified in
Article 21.
18. BACKFILLING PIPE TRENCHES
A. Backfilling shall begin as soon as possible after the pipe has been
placed and the pipe joints have been inspected and shall proceed
without interruption. The zone around the pipe shall be packed full
by hand with the material shown on the drawings. If common fill is
shown or specifically approved by the Engineer in writing, it shall
be free of hard lumps or stones with any dimension greater than 3".
The fill material shall be placed and compacted to a level two feet
above the top of the pipe. The backfill shall be carried up
uniformly on both sides of the pipe using care not to disturb the
pipe. There shall be at least one man tamping fill for each man
shovelling material into the trench.
B. With the exception mentioned below in this paragraph, trenches shall
not be backfilled at pipe joints until after that section of the
pipeline has successfully passed any specified tests. Should the
. Contractor wish to minimize the use of lights and barricades and the
obstruction of traffic, he may at his own risk, backfill the entire
trench. He shall however, be responsible for removing and replacing
backfill, at his own expense, should he be ordered to do so in order
to locate and repair or replace leaking or defective joints or pipe.
(1) Materials. The nature of the backfill materials will govern
both their acceptability and compaction. The material and the
methods shall be subject to the approval and direction of the
Engineer. No stone or rock fragment larger than 9 inches in
greatest dimension shall be placed in the backfill nor shall
large masses of backfill material be dropped into the trench in
such a manner as to endanger the pipeline. If necessary, a
timber grillage shall be used to break the fall of material
dropped from a height of more than 5 feet. Pieces of bituminous
pavement shall be excluded from the backfill unless their use is
expressly permitted, in which case they shall be broken up as
directed.
Material for backfill shall not contain vegetation, masses of
roots, individual roots more than 18 inches long or more than
inch in diameter, or porous matter. Organic matter shall not
exceed minor quantities and shall be well distributed.
(2) Compaction. All compaction shall be accomplished by tamping or,
under appropriate circumstances, rolling. The material shall be
• deposited and spread in uniform, parallel layers not exceeding
8" thick before compaction. Each layer shall be tamped as
. 222-11
required so as to obtain a thoroughly compacted mass. If
necessary, the Contractor shall furnish and use an adequate
number of power-driven tampers, each weighing at least 20
pounds, for this purpose. Care shall be taken that the material
close to the bank, as well as in all other portions of the
trench, is thoroughly compacted. When trench width and depth
are sufficient to make it feasible and it can be done
effectively and without damage to the pipe, backfill may, on
approval, be compacted by suitable rollers, tractors, or similar
powered equipment. The rate at which backfill material is
deposited in the trench shall not exceed that permitted by the
facilities for its spreading, leveling, and • compaction. If
necessary to ensure proper compaction, the material shall first
be wet by sprinkling.
However, no compacting shall be done when the material is too
wet to be compacted properly. At such times, the work shall be
suspended, until backfill materials have dried out sufficiently
to permit proper compacting, or other precautions shall be taken
as may be necessary to obtain proper compaction.
(3) Water-jetting and puddling to compact backfill shall not be
allowed.
• 19. MATERIAL FOR FILLING & EMBANKMENTS
A. Common Fill - Selected Material
(1) Common fill shall be on-site excavated material consisting of
earth and stone that is free of vegetable or spongy material,
broken pavement, construction debris and stone larger than 8" in
the largest dimension. Common fill shall, in general, be used
for building embankments and for miscellaneous fill where so
indicated on the drawings or where its. use is specifically
permitted by the Engineer. Off-site material shall be used as
needed.
B. Bank Run .Gravel
(1) Bank Run Gravel shall be used for backfill around structures to
the limits shown on the drawings. Bank Run Gravel shall consist
of hard, durable granular material graded as given below. It
shall not contain vegetation, masses of roots more than 18" long
or more than k" in diameter and shall be substantially free from
loam and other organic matter, clay and other fine or harmful
substanced.

D. Screened Gravel
Screened gravel shall be well graded in size from 1/4" to or of
other size approved. The gravel shall consist of clean, hard,
durable particles or fragments free from dirt, vegetable or other
objectionable matter and an excess of soft, thin elongated, laminated
-or disintegrated pieces. Crushed stone shall not be allowed instead
of screened gravel.
E. Crushed Stone
The Contractor shall furnish, place, and compact crushed stone as
indicated on the drawings or as directed and as herein specified.
Crushed stone shall be well graded meeting the requirements of ASTM
Designation C-33, Gradation 67 (3/4-inch to No. 4) . It shall not
contain vegetation, masses of roots, loam and other organic matter,
clay, and other fine or harmful substances.
20. PLACING 6 COMPACTING MATERIAL
A. After the subgrade has been prepared as hereinabove specified in the
• clearing and grubbing paragraph of this Section, the material shall
be placed thereon and built up in successive layers until it has
reached the required elevation.
222-13
B. Unless otherwise specified or indicated on the drawings, where fill
is required to raise the subgrade for foundation under concrete slabs
or for subbase under pavement, such fill shall be compacted gravel
and be placed in layers not exceeding 8 inches (loose measure) in
thickness. Each layer shall be moistened during compaction to a
moisture content such that the required degree of compaction may be
obtained. Compaction shall be in a manner approved by the Engineer.
C. Where filling is done beside foundation walls, Bank Run Gravel shall
be brought up essentially at the same height on both sides at all
times until the maximum level at the lower side is reached. Where a
higher level of fill is required on one side of the foundation wall,
the higher level must be properly compacted. If a power roller is
used for compaction, the roller edge must not approach nearer than
four feet from the face of the wall. The space so left shall be
machine-tamped to the required density.
D. Fill for various applications shall be compacted to the following
minimum densities,_ determined by ASTM Designation D-1557 Method D.
(1) Drainage Fill and 957 of maximum
Compacted Fill density at optimum
moisture content
(2) All other fill and backfill 907 of maximum density
