Contractor.
If the Contractor, in. the course of the work, finds any discrepancy
between the plans and the physical conditions of the locality, or any errors
or omissions in the plans or in the layout as given by points and instruc-
tions, it shall be his duty to immediately inform the Engineer in writing,
and the Engineer shall promptly verify the same. Any work after such
discovery, until authorized, will be done at the Contractor's risk.
Neither party shall employ or hire any employee of the other party
without the other party's consent.
15.. CHANGES IN THE WORK:
The Owner, without invalidating the Contract, may order extra
work or make changes by altering, adding to, or. deducting from the work,
the Contract Sum being adjusted accordingly. All such work shall be
executed under the conditions of the original Contract except that any
claim for extension of time caused thereby shall be adjusted at the time
of ordering such change.
In giving instructions, the Engineer shall have authority to make
minor changes in the work, not involving extra cost, and not inconsistent
with the purposes of the work, but otherwise, except in an emergency
endangering life or property, no extra work or change. shall be made'
unless in pursuance of a written order by the Engineer, and no claim for
an addition to the Contract Sum shall be valid unless so ordered.

the Engineer may direct, a correct account of the net cost of labor and
materials, together with vouchers. In any case, the Engineer shall certify
to the amount including reasonable allowance for overhead and profit, due
to the Contractor. Pending final determination of value, payments on ac-
count of changes shall be made on the Engineer's estimate.

contractor employed by the Owner, or by changes ordered in the work,
or by strikes, lockouts, fire, unusual delay in transportation, unavoidable
casualties or any causes beyond the Contractor's control, or by any causes
which the Engineer shall decide to justify*the delay, then the time of com-
pletion shall be extended for such reasonable time as the Owner may decide.
No such extension shall be made for delay occurring more than
seven (7) days before claim therefor is made in writing to the Engineer.
In the case of a continuing cause of delay, only one (1) claim is necessary.
GC-8
If no schedule or agreement stating the dates upon which drawings
lie shall be furnished is made, then no claim for delay shall be allowed on

The Owner shall have the right to take possession of and use any
completed or partially completed portions of the work, notwithstanding
the time for completing the entire work or such portions which may not
have expired; but such taking possession and use shall not be deemed an
acceptance of any work not completed in accordance with the Contract
Documents. If such prior use increases the cost of or delays the work,
the Contractor shall be entitled to such extra compensation, or extension
of time, or both, as the Engineer may determine.
1 GC-10

shall become due until the Contractor shall deliver to the Owner a com-
plete release of all liens arising out of this Contract, or receipts in full
in lieu thereof. In either case an affidavit shall be furnished to the Owner
stating that so far as he has knowledge or information, the releases and
receipts include all the labor and material for which a lien could be filed.

TECHNICAL, SPECIFICATIONS
SECTION I
MATERIALS OF CONSTRUCTION
1. MATERIALS AND INSPECTION:
All materials and equipment used on this work shall be new, of the
best quality, and shall meet the requirements of these specifications.
Materials shall be sampled and tested in accordance with current ASTM
Specifications or such others as specified hereinafter. The Contractor
will be required to furnish certificates of conformance to ASTM or other
applicable specifications. Materials shall be stored in such a manner
that their condition is equivalent to new when installed.
Whenever in these specifications reference is made to the require-
ments of the ASTM (American Society for Testing Materials), AWWA
(American Water Works Association), ASA (American Standards Associa-
tion), or other standard specifications, the latest modifications or revisions
of such specifications shall be applicable for use.
All material to be used in this work will be inspected before being
placed and all rejected material must be removed immediately and not
used in the work under this Contract. Any material installed or placed
without inspection shall be removed and replaced with new material if so
directed by the Engineer.
The Contractor will be required to furnish such laborers as may be
necessary to aid the Engineer in the examination and culling of material.
The Contractor shall pay for all tests required by the specifications.
Such tests shall be performed by a competent independent laboratory ap-
proved by the Engineer on test specimens selected by the Contractor under
the direct supervision of the Engineer. Copies of all test results shall be
submitted to the Engineer directly from the testing laboratory.
® 2. CONCRETE AGGREGATES:
The source of supply of the aggregates shall be approved by the
Engineer before delivery or use is started. Representative preliminary
I-1
samples of the materials to be used shall be submitted by the Contractor
to the Engineer for examination and tests at least 45 days prior to use in
the project.
Aggregates shall be stored and handled so as to ensure the preser-
vation of their quality and fitness for use, and shall be located so as to
facilitate prompt inspection. All equipment for handling and transporting
aggregates must be clean before any aggregates are placed therein.
In no case will the use of pit-run or naturally mixed aggregates
be permitted. Aggregates must, in every case, be screened and washed,
and all fine and coarse aggregates stored separately and kept clean. The
mixing of different kinds of aggregates from different sources in one stor-
age pile or alternating batches of different aggregates will not be permitted.
Aggregates containing lumps of frozen or partially cemented material shall
not be used.
The tests to which the aggregates will be subjected will include,
but not necessarily be limited to, specific gravity, absorption, Los
Angeles abrasion, soundness in magnesium and sodium sulphate, freezing
and thawing in concrete, alkali-aggregate reaction and organic impurities,
and any other tests that are necessary to demonstrate that concrete of
acceptable quality can be produced from the materials proposed.
Coarse Aggregate. The material to be used as coarse aggregate
in the concrete shall be gravel or crushed limestone. Gravel aggregates
shall be clean, washed gravel, consisting of hard, strong, durable pieces
free from dust, loam, clay, alkali, organic impurities, adherent coatings,
or other deleterious substances, and from thin, porous, elongated or
laminated particles. Crushed limestone aggregate shall consist of uncoated
particles of sound, durable rock of uniform quality, without an excess of
flat, elongated or laminated pieces. No surface yellow or soft stone shall
be permitted. The specific gravity of the stone shall'be.not less than 2. 56.
Coarse aggregates shall conform to the requirements of Specifications for
Concrete Aggregates, ASTM Designation C33.
The gravel or crushed limestone shall be graded to meet the follow-
ing requirements using the U. S. Standard Sieve Series:
® Sieve Sizes Percentage Passing
1-1/2-inch 10016 by weight
1-inch 95-10010 by weight
3/4-inch 65- 80% by weight
3/8-inch 15- 401a by weight
No. 4 0- 5% by weight
No. 8 0- 2% by weight
I-2
The coarse aggregate shall be uniformly graded and should the
grading vary between loads from the maximum to the minimum limits of
these specifications, such variation will be sufficient grounds for rejection.
To ensure the production of suitable aggregates, complying in all
respects with these specifications, the aggregate plant shall be subject to
the approval of the Engineer and no deliveries of aggregate shall be made
until the operating conditions of the plant,from which the gravel is to be
delivered, have been inspected and approved.
No stockpiling of the coarse aggregates will be permitted on public
streets, alleys, or highways. If the aggregates are to be stored in other
than bins or hoppers, the aggregates must be deposited on a clean, hard
surface. In no case shall aggregates be dumped directly on the ground.
The use of frozen aggregates will not be permitted. When the
temperature of the air permits concreting to be carried on, the aggregates
must be thawed out, thoroughly removing all frost before incorporating
same in the concrete mixture.
Fine Aggregate. The fine aggregate to be used in concrete shall
consist of clean, natural sand of hard, strong, durable, uncoated grains,

fla drawings shall be submitted for approval.
Payment for shop drawings shall be included in the price bid for
the item of equipment or material for which the shop drawing is furnished.
3. HANDLING OF MATERIALS:
All materials shall be delivered and distributed to the site of the
work by the Contractor.
Payment for work described in this paragraph shall be included in
the price bid for the item containing the various pieces of equipment or
material.
S 4. CONCRETE:
The Contractor's attention is called to the fact that the specifica-
tions for Class A and Class B concrete carry three limiting factors, all of
Iwhich shall be complied with. These factors are: (1) minimum strength,
II-1
(2) minimum volume of cement per cubic yard of concrete, and (3) maxi-
mum volume of water per sack of cement.
a. Classes of Concrete. Class C concrete may be used for fill in
trenches as required for pipe in rock trench, or for overexcavation of the
trench. Class B concrete shall be used for encasement and cradling of
pipe or for blocking for cast iron or ductile iron pipe. All other concrete
used on this project shall be Class A concrete, unless otherwise specifi-
cally noted on the Plans.
b. Class A Concrete. Class A concrete shall have a minimum
compressive strength of 3, 500 pounds per square inch in 28 days and shall
consist of the mixture which results in one cubic yard of concrete to each
batch of fine and coarse aggregate and water used to each six sacks of
cement. Total water shall be limited to a maximum of 6-1/2 gallons per
sack of cement. The fine and coarse aggregates for each batch of concrete
where monolithic construction is to be carried out shall be accurately
weighed; the exact weight of each batch shall be that necessary to produce
a dense workable concrete with the yield per sack of cement as herein
specified when mixed within the limitations of the amount of water herein
specified. Where small batches of concrete are to be used and the concrete
is mixed on the site, Class A concrete shall be considered as that mixture
MID consisting of 2 cubic feet of dry fine aggregate, not more than 3-1/2 cubic
feet of dry coarse aggregate to each sack of cement, mixed with not more
than 6-1/2 gallons of total added water.
c. Class B Concrete. Class B concrete shall have a minimum
compressive strength of 2, 000 pounds per square inch in 28 days and shall
consist of the mixture which results in one cubic yard of concrete to each
batch of fine and coarse aggregate and water used to each four sacks of
cement. Total water shall be limited to a maximum of 8-1/2 gallons per
sack of cement. Where small batches of concrete are to be used and the
concrete is mixed on the site, Class B concrete shall be considered as that
mixture consisting of 3 cubic feet of dry fine aggregate, not more than 5
cubic feet of dry coarse aggregate to each sack of cement, mixed with not
more than 8-1/2 gallons of total added water.
d. Class C Concrete. Class C concrete shall consist of the mix-
ture which results in one cubic yard of concrete to each batch of fine and
coarse aggregate and water used to each two sacks of cement. Total water
shall be limited to a maximum of 9- 1/2 gallons per sack of cement.
e. Determination of Added Water. In determining the amount of
added water, allowance should be made for the moisture content in the
II-2
aggregates. In measuring the fine aggregate by volume For small batches
of concrete, if the aggregate is wet, allowance should be made for the
bulking on account of the presence of moisture.
f. Proportioning. The concrete mixtures will be approved by the
Engineer from design mix tests. All materials required for these tests
shall be supplied by the Contractor from samples taken from the approved
source of supply. At any time during the construction period, the relative
weights of fine and coarse aggregates as determined by the original mix
design may be varied slightly in order to ensure the use of the least amount
of fine aggregate which will produce workable concrete with the slumps
specified.
The water content of the concrete shall at all times be the mini-
mum necessary to properly place the concrete. It shall be regulated as
required to adjust for any variation in the moisture content or grading of
the aggregates. Addition of water to compensate for stiffening of the con-
sistency before placing will not be permitted. Uniformity of concrete
consistency from batch to batch will be required.
All concrete shall be proportioned by weight. Allowance must
be made for the weight of moisture in the aggreates in order to deter-
mine the amount of additional water required for the given concrete mix
design.
g. Air-Entrained Concrete. An air-entraining admixture, ap-
proved by the Engineer may be used in the concrete should the Contractor
desire to improve the workability of the concrete. No additional payment
will be made for the use of an admixture approved by the Engineer at the
Contractor's request. The air-entraining admixture shall be added to the
concrete during the process of mixing. The agents shall be accurately
measured and dispensed by means of an approved adjustable mechanical
dispenser which will automatically and gradually discharge the required
amount of material into the mixing water. The entire amount of air-
entraining agent shall be fully discharged before all of the mixing water
has entered the drum of the mixer. The dispenser shall be so constructed
that it can be accurately calibrated for the quantity of agent discharged at
various settings and shall be provided with means by which the discharge
can be readily diverted from the stream of mixing water to a container for
measurement.
II-3
1
Class A concrete which contains an approved admixture shall con-
tain 5 per cent plus or minus 1 per cent of entrained air by volume. The
volume of entrained air in the freshly mixed concrete will be measured
by the Engineer by the volumetric method, Test for Air Content of Freshly
Mixed Concrete by the Volumetric Method, ASTM Designation C173, or by
the pressure method, Test for Air Content of Freshly Mixed Concrete by
the Pressure Method, ASTM Designation C231. Mixes will be designed for
the recommended air content and adequate control shall be provided to keep
the air content within the required limits.
h. Consistency. The consistency of the concrete shall be such that
the slump, when measured according to Test for Slump of Portland Cement
Concrete, ASTM Designation C143, is the lowest compatible with work-
ability and ease of placing. In general, the slump shall not exceed 3 inches.
No additional water shall be added at the site of placement except
with permission and under strict supervision of the Engineer and then only
in an emergency. Such additional water shall be added only in small in-
crements and then only in the smallest amount necessary within the required
limits of consistency for the particular work, and shall be uniformly mixed
and incorporated into the unplaced concrete before deposition in the forms.
i. Mixing. Concrete required for blocking, encasement and other
uses incidental to the installation of pipe: involving small quantities may
either be mixed by machine or by hand. All other concrete shall be mixed
by machine.
j. Mixing by Machine. The mixer to be used shall be so designed as
to take one complete batch of materials using whole bags of cement only
and to mix that batch thoroughly before any portion of it is withdrawn and
any portion of the succeeding batch is introduced. In no case shall the
volume of the batch to be mixed be greater than the amount of materials
which can be loaded and mixed in the mixer without any loss during the
loading or mixing by spilling. The mixer shall be equipped with a water
tank accurately calibrated so that the required amount of water can be
added to each batch, and with a batch meter or other suitable attachment
for satisfactorily locking the discharging device so as to prevent the
emptying of the drum until all of the materials have been mixed together
rfor the minimum time required.
r After all the ingredients, including water, have been placed in the
drum, they shall be thoroughly mixed in the mixer for a period of not less
r
II-4
r
than one minute. During this period the drum shall make not less than 14
nor more than 20 revolutions per minute.
k. Central Plant Concrete Mixing. . In lieu of mixing on the job by
machine or by hand, central plant: concrete will be permitted, provided the
concrete conforms to the proportioning hereinbefore specified, is mixed at
a central plant or in transit in equipment approved by the Engineer, and in
conformity with current ASTM Specifications for Ready-Mixed Concrete
(C94). The concrete shall be delivered to the job in batches of such size
that it can be conveniently handled without setting up during placing, without
segregation of aggregates, and of satisfactory consistency to ensure a uni-
form concrete mixture when placed.
1. Hand Mixing. Where hand mixing of concrete is permitted, it
shall be carried out on watertight boards or pans in not more than 2-sack
batches. The cement and fine aggregates shall first be mixed dry until a
uniform color is obtained. The water shall then be gradually added and
the mixture made into a mortar, adding additional water until the desired
consistency is reached. The coarse aggregate shall then be spread upon
the mortar and covered with mortar. The whom. mass shall then be cut
through and turned over not less than four times or until thoroughly mixed
with a uniform homogeneous mixture obtained before being removed from
the mixing board or pan in the place where it is to be deposited. The total
amount of water shall not exceed the limitations hereinbefore specified for
Class A, I3, or C concrete.
m. Forms. Forms for concrete shall be rigidly braced so that
they cannot bulge or warp and leave an unworkmanlike finished surface.
They may be constructed of any material with sufficient strength which
will give.the finished work a satisfactory surface. They must be sufficiently
tight so that mortar cannot escape from the concrete in appreciable quantity.
Forms shall be cleaned and be thoroughly moistened or treated with form
oil before concrete is placed. All exposed exterior concrete corners shall
be chamfered one inch.
n. Reinforcing. All reinforcing shall be rigidly fastened in the forms
prior to the pouring of any concrete in such manner that the steel will be
held accurately to the location shown on the Plans. Steel shall be cleaned
of rust, scale, oil, or other surface matter before being placed in forms.
o. Placing. The methods and equipment used for transporting con-
crete and the time that elapses during transportation shall be such as will
not cause appreciable segregation of coarse aggregate, or slump loss in
1 excess of one inch in the concrete as it is placed in the project.
II-5
Before placing concrete in the forms or in the place of deposit, all
debris and foreign materials, soft earth, or mud, shall be removed. Water
shall be removed from the place of deposit. No concrete shall be placed in
water. Steel or wood forms shall be oiled and treated to prevent adhesion
of concrete and damage to the concrete surface upon removal of the forms.
Concrete shall be placed as nearly as practicable in its final position to
avoid segregation due to rehandling or flowing. Concreting shall be carried
on at such a rate that the concrete is at all times plastic and flows readily
into the forms and around reinforcing. No concrete shall be used that has
partially hardened or has been contaminated by foreign material or that has
been retempered. Placing of concrete shall be performed only in the pres-
ence of"a duly authorized representative of the Engineer unless inspection
is waived in each specific case.
The temperature of concrete when it is being placed shall be not
more than 90 degrees F. or less 40 degrees F.
Concrete shall be placed before initial set has occurred.
Before depositing concrete on or against concrete which has taken
its initial set, the surface of the hardened concrete shall be broken off
down to coarse aggregate and wire-brushed to remove foreign matter and
laitance. A layer of grout of the same cement-sand ratio as the concrete
without coarse aggregate shall be placed to a thickness of 1 to 2 inches on
the brushed surface after which the new concrete shall be placed immediately.
When concreting has once started, it shall be carried on as a con-
tinuous operation until the section or structural unit is completed.
All concrete shall be thoroughly compacted by vibrators, spading
or other suitable means during the operation of placing, to ensure that
concrete will flow around all reinforcement, embedded fixtures and into
the corners of the forms to give a dense finished product with true sur-
faces free from honeycombing, segregation and other imperfections. Con-
' crete shall be placed in horizontal layers of no greater depth than 18,inches.
Concrete shall be placed at a suitable rate to avoid the formation of unauthor-
ized cold joints. In no case shall vibrators be used to transport the concrete
inside the forms.
Care shall be taken when placing concrete through reinforcing steel
so that the segregation of coarse aggregate is kept to a minimum. In such
cases, spouts, elephant trunks, or other suitable means shall be used. The
free fall of concrete shall be held to a practical minimum and shall not ex-
ceed 5 feet at any time.
II-6
I
The placing of concrete shall be so planned that horizontal and
vertical construction joints are made where shown on the drawings or
b. where approved by the Engineer. Structural keys shown on the Plans shall
have a minimum width of 4 inches and a depth of 1-1/2 inches. The con-
crete shall be left with a roughened surface for construction joints. Water-
stops shall be placed as shown on the Plans and in all construction joints
subject to water on one side and where the opposite side is intended to be
dry.
p. Protection. The Contractor shall protect all concrete against
injury until final acceptance by the Engineer.
During cold weather all concrete materials and all reinforcement,
forms, fill material, and ground with which the concrete will be placed
in contact, shall be free of frost or ice and snow. Whenever the tempera-
ture of the surrounding area is 40 degrees F. and falling, no concrete
shall be placed unless the Contractor has on hand sufficient, suitable, and
approved means of protecting the concrete. Whenever the temperature of
the surrounding air is between 40 degrees F. and 32 degrees F. , all con-
crete placed in the forms shall have a temperature between 50 and 70 de-
grees F. Adequate means shall be provided for maintaining a temperature
in the surrounding air not less than 70 degrees F. for at least three days, or
50 degrees F. for five days. The housing, covering, or other protection
used shall remain intact and in place at least 24 hours after artificial heat-
ing is discontinued. Care must be used to prevent fire hazards when using
heating and no fire or excessive heat shall be permitted near or in direct
contact with concrete at any time. Salt or chemicals shall not be used in
the concrete to prevent freezing.
Whenever the temperature of the surrounding air reaches 32 de-
grees F. , or lower, concrete shall not be placed except with the approval
of the Engineer who shall state the time in addition to that specified herein
that artificial heat and protection must be supplied. Whenever the tempera-
ture of the surrounding air reaches 20 degrees F. or lower, no concrete
shall be placed except for emergencies and only with special permission
and supervision of the Engineer.
q. Curing of Concrete. All concrete placed when the temperature
is above 40 degrees F. shall be either sprinkled continuously for 72 hours,
® or shall be covered with burlap which shall be kept moist for at least 72
hours. The use of membrane curing shall be permitted only when approved
by the Engineer. The membrane curing compound shall be of a type ap-
proved by the Engineer.
I
11-7
I
Concrete cured with water shall be kept continually wet for at least
72 hours immediately following placement of the concrete, or until covered
with fresh concrete. The concrete to be cured shall be kept wet by cover-
ing with water-saturated material or by a system of perforated pipes,
mechanical sprinklers, or porous hose, or by any other approved method
which will keep all surfaces to be cured continuously (not periodically)
wet. Water curing shall commence as soon as the concrete has hardened
sufficiently to prevent damage. Water used for curing shall meet the re-
quirements for water used for mixing concrete.
Membrane curing compound shall be applied to formed surfaces
immediately after the forms are removed. If any areas require patching,
or any other surface treatment, the membrane curing shall not be applied
to that area until after the area has been repaired. The area to be repaired
shall be kept continually wet by a method approved by the Engineer prior
to the patching or surface treatment of the area. Following the patching or
surface treatment and a 24-hour period of water curing, the area may, at
the Contractor's option, be treated with membrane curing compound for
the remainder of the curing period.
Any membrane curing compound applied to surfaces that require
patching or other surface treatment, or to surfaces that are specified to
be water cured as listed above, shall be completely removed by sand
blasting.
Where membrane curing is used, following removal of the forms,
the surfaces shall be thoroughly moistened with water and the curing com-
pound applied as soon as free water disappears. The curing compound
shall be applied to unformed surfaces as soon as free water disappears
or immediately following finishing where special finishing operations are e
specified. The curing compound shall. be applied in a two-coat continuous
operation by approved power-spraying equipment and at a uniform coverage
of not more than 300 square feet per gallon for each coat. All concrete
surfaces on which the curing compound has been applied, shall be ade-
quately protected for a period of 72 hours from any cause which will disrupt
the continuity of the curing membrane. Any curing membrane damaged
during the 72-hour period, shall be restored as directed by the Engineer.
All concrete and reinforcing steel shown on the Plans or required
by the specifications shall be included in the unit price bid for each item
in which the concrete is used, and will not be measured or paid for sepa-
rately, except Class B and C concrete used for pipe bedding or pipe encase-
ment will be measured and paid for as noted elsewhere in these specifications.

S. INTERFERENCE WITH TRAFFIC:
It must be recognized that in some instances the work of this proj-
ect involves the construction of sewers along the public streets of the de-
veloped municipality. Access to abutting property should be provided
wherever it is possible without interference with the construction opera-
tion. The Contractor will be required to provide satisfactory bridges to
allow traffic to cross over the excavated trench where the street intersec-
tion is traversed by open cut excavation. Care should be taken to avoid
blocking of access to fire hydrants during this construction. After the
sewer is constructed and the backfill made over the completed sewer, a
temporary pavement is to be laid down and the street open to traffic in
order to provide access to abutting property as soon as possible. Open
cut crossings are to be maintained for 60 days with macadam or other sat-
isfactory material so as to provide an all-weather roadway surface, after
which time the restoration of the permanent pavement of the type ordered
ca by the Engineer shall be carried out.
Payment for all work described in this paragraph shall be included
in the unit price bid for "Class B Trench Excavation. "
6. PROTECTION OF TREES AND RESTORATION OF LANDSCAPED
AREAS:
Wh er ever the sewe r i s to be bu ilt in a right-of-way located along
occupied property which has been landscaped or in the sidewalk space ad-
jacent to trees, and wherever trees are encountered adjacent to the line
of the work, the Contractor's operations must be so organized and carried
out as not to disturb or destroy any trees except where permission to do
so has been obtained from the property owners with the Engineer's approval.
The existing surface shall not be disturbed beyond the limits of the right-
of-way, which shall include the necessary area for storing of materials of
construction and excavated materials. Upon completion of the work, the
surface shall be replaced to conform to the original surface. Where turf
has been disturbed, the completed backfilled surface shall be sodded or
raked and seeded during the proper'.time of the year. Where excavated
material is stored adjacent to trees, it shall be carried away so as not to
cause injury to them in any way. If necessary, boxing shall be provided
around trees, plants or shrubs. Upon completion of the work, such box-
ing shall be removed and the original condition restored. Payment for
carrying out the necessary protection and restoration of trees and land-
scaped areas, as herein specified, shall be included in the payments made
at the price bid per cubic yard for "Class B Trench Excavation. "
II-9
Where excavation is made through surface rock, the Contractor may
be required to restore the surface to its original contour. The Contractor
4D will replace the surface rock with Class C concrete at the direction of the
Engineer. Such concrete will be measured and paid for at the price bid
per cubic yard for "Class C Concrete. "
7. PROTECTION OF EXISTING STRUCTURES:
The work must be carried out in such a manner that all structures
or improvements along and adjacent to the new sewer construction are
properly protected. Any damage occurring to property of others because
of the Contractor's operation shall be repaired to the satisfaction of the
owner of said private property by the Contractor and the cost considered
as covered in the item of "Class B Trench Excavation. "
8. PROTECTION OF POLE LINES, WATER AND GAS PIPES, AND ALL .
OTHER UNDERGROUND UTILITIES:
On the Plans, for the work to be constructed under this Contract,
is shown the record information which has been obtained from the utilities
for underground pipes or conduits which exist along the line of the proposed
sewers or at the location of the other improvements. The City does not
guarantee the accuracy of these locations, but merely indicates the infor-
mation which has been obtained from the companies owning such under-
ground pipes or conduits. The locations of utility poles, shown as noted
at the time of the survey, may have since been changed. It is assumed
that the Contractor will make a field 'inspection of the locations of the
work, and note all poles and overhead improvements which may affect
his method of operation in the construction of the sewers and other im-
provements at such locations.
Such poles, overhead wires, underground pipes and conduits that
may exist or may be encountered are to be protected at the Contractor's
expense. Any expense or inconvenience caused by their existence, and
the necessary protection during the construction of the sewers or other
facilities adjacent thereto, shall be considered as covered and included
in the price bid for "Class B Trench Excavation, " or the lump sum bid
for other improvements. The Contractor shall notify the utility owners
in advance of any construction which would expose underground pipelines
or otherwise affect their safety.
9. REMOVAL AND REPLACEMENT OF SECONDARY PAVEMENTS:
Usable dirt roads and secondary pavements, consisting largely of
crushed rock and cinders, which are to be removed in the course of the
II-14
construction, shall be replaced with a layer of crushed rock compacted to
a minimum thickness of 8 inches. The road surface shall be maintained for
a period of 60 days after initial replacement to allow for settlement and con-
solidation of the backfill, after which it shall be bladed to a smooth and uni-
form surface.
No separate payment for the removal and restoration of secondary
pavements shall be made. Payment for such removal and replacement
shall be considered as included in the price bid for "Class B Trench
Excavation. "
10. REMOVAL AND RESTORATION OF ASPHALTIC PAVEMENT:
The asphaltic pavement to be removed shall be cut to neat straight
lines. After completion of the granular backfill, a layer of crushed rock
shall be compacted to a minimum thickness of 8 inches. The rock course
shall be primed and covered with a minimum of 2 inches of asphaltic con-
crete wearing surface to the cross section and grade as set by the Engineer
to meet the present undisturbed pavement on each side of the area restored.
Asphaltic concrete and placing methods used shall be similar in quality to
the original pavement and approved by the Engineer. The Contractor shall
restore the surface to the grade specified by the Engineer, should any
settlement take place within 1 year of the initial pavement restoration,
Payment for the removal and restoration of asphaltic concrete shall
be limited to an area calculated on a width equal to the trench payline
widths herein specified for the particular size of sewer installed, multi-
plied by the length of pavement restored. Payment will be made at the
price bid per square yard for "Restoration of Asphaltic Pavement, " which
payment shall include the whole cost of removing the existing pavement
within cut straight lines, disposing of the material removed from the line
of work, preparing the subgrade, furnishing of plant, labor, materials,
tools and all other incidentals which may be necessary for removing and
restoring the pavement.
11. REMOVAL AND RESTORATION OF CONCRETE CURB:
4
Where the alignment of the sewers requires the removal of existing
concrete curb, removal shall be to the full width of the concrete pavement
removal. The curb shall be cut in a neat straight line and shall be replaced
to the same cross section as that removed, using Class A concrete.
Payment for the removal and restoration of concrete curb will be
made at the price bid per lineal foot for ''Restoration of Concrete Curb, "
J II-11
which payment shall include the whole cost of removing the curb and laying
the new sections as required. Curb paralleling the sewer trench will not
be measured or paid for unless it falls within a distance equal to one-half
the payline width of the trench involved.
12. SIDEWALKS AND DRIVEWAYS:
Where sidewalk's or driveways are removed, the Contractor shall
replace them with materials similar to those removed and to the reason-
able satisfaction of the owner.
No separate payment for the removal and restoration of sidewalks
and driveways shall be made. Payment for such removal and replacement
shall be considered as included in the price bid for "Class B Trench
Excavation. "
13. TRENCH EXCAVATION:
The work included under "Trench Excavation" shall comprise any
necessary clearing of the line on which the sewer is to be constructed; of
making all excavations of all materials of every description which may be
encountered and as classified hereinafter as "Trench Excavation, Class All
and "Trench Excavation, Class B"; of furnishing and placing of all shoring,
sheeting and bracing which may be necessary to protect the work and to
execute it; of shaping the bottom; of furnishing all equipment which may be
necessary to keep the trenches free from water so that the sewers and con-
crete may be placed in the dry; of providing for the uninterrupted flow of
surface water or sewage adjacent to the line of the work during the progress
of the work so as not.to interfere with the natural surface flows; of protect-
ing all pipes, conduits, culverts, bridges and all other public and private
property which may be endangered by the work; and of hauling away all sur-
plus excavated material,
A series of borings was taken along the entire length of the con-
struction. The results of these borings are shown on the Plans for infor-
mation only. There is no expressed or implied agreement or guarantee
that the depths or character of materials are correctly shown or that
conditions affecting the work will not differ from those shown on the Plans.
All excavation shall be carried out accurately to the line and grade
as shown on the Plans and as established by the Engineer.
If the bottom of the excavation is found to be unstable or to include
Iashes, cinders, refuse, vegetable or other organic materials considered
H_12
unsuitable by the Engineer, the Contractor shall excavate and remove such
unsuitable material to the depth required and backfill to the original sub-
grade with granular backfill, well-compacted by means of mechanical
tampers or vibrators in 6-inch layers, except as noted hereinafter. If
over-excavation is required by the Engineer, the quantity of such authorized
additional excavation shall be determined by the Engineer, and the Con-
tractor shall be paid by the City for the over-excavation at the unit price
bid for "Class B Trench Excavation. " Any unauthorized over-excavation
shall also be backfilled as described above but no payment shall be made
for such over-excavation and backfilling.
All excavation shall be dewatered before any construction is under-
taken therein. Concrete shall be placed only upon dry firm foundation
material and pipe shall be laid only in dry trenches.
The responsibility of the Contractor with respect to the use of ex-
plosives in blasting includes compliance with all laws, rules and regula-
tions of the State, the City and the insuror, governing the keeping, storage,
use, manufacture, sale, handling, transportation or other distribution of
explosives. All operations involving the handling, storage and use of ex-
plosives shall be conducted with every precaution by trained, reliable men
under satisfactory supervision. Blasts shall not be fired until all persons
in the vicinity have had ample notice and have reached positions out of
danger therefrom. The Contractor shall advise the Engineer in advance
when charges are to be set off.
After a blast is fired, the Contractor shall thoroughly scale the
excavation, removing all loose and shattered rock or other loose material
which may be dangerous to the workmen, and the excavation shall be made
safe before proceeding with the work. The fact that the removal of loose
or shattered material may enlarge: the excavation beyond the required
limits shall not relieve the Contractor from the necessity for making such
removal, and the Contractor shall not be entitled to compensation therefor,
Class A material is any material, such as solid limestone or hard
stone in original bed or well-defined ledges, large boulders, detached
pieces of limestone or hard stone, or mass concrete more than 9 cubic
feet in volume, any of which cannot be removed by heavy equipment without
drilling and blasting or wedging.
Where rock or other hard material occurs in the trench so that any
portion of the pipe would rest on rock or hard material, or at the direction
of the Engineer, the trench excavation shall be carried to a depth below the
planned grade so that no rock is closer than 2 inches to the outside of the
H-13
pipe at any point. The width of trenches shall be ample to permit the pipe
to be laid, jointed, and covered properly.
Class B material is any material not included in Class A excavation.
Trenches shall be dug so that all pipes can be laid to the alignment
and depth required. The width of trenches shall be ample to permit the pipe
VIR to be laid and jointed properly and the backfill to be placed and compacted.
Additional width shall be provided where shoring or bracing is used.
In order to avoid superimposed loading in excess of the designed
and specified pipe strength and to provide sufficient room for proper in-
stallation and bedding of pipe, the trench widths for the sewer pipe sizes
used shall be kept within the limits specified as follows:
Size of Pipe Minimum Width Maximum Width
�.
8" - 12" 21-411 2'-10"
1511 21-811 31-211 L
18" 2'-1111 3'-6"
Ile 2111 31-311 31-1011
24" 31-611 41-011
27" 3'-9" 4'-411
30" 4'-1" 4C "
'-8
36" 4'-8" 5'-0"
The Contractor may, at his option, where working conditions and
rights-of-way permit, and with the approval of the Engineer, excavate
sewer trenches with sloping sides, but with the following limitations:
Only braced vertical trenches will be permitted in streets, alleys
or easements which are paved, or in locations where the trenches are in
close proximity to utilities, buildings, railroad tracks, or other installa-
tions which could be endangered by the excavation.
MWhere trenches are excavated with sloping sides for pipe sewers
to be installed, the slope shall not extend below a point one foot above the
extrados of the pipe, and the trench excavation below the point shall be
carried out with vertical sides for widths not exceeding the maximum
widths provided for in these specifications above.
Any trench excavated with sloping sides for pipe sewers which has
a width one foot above the top of the pipe in excess of the maximum trench
II-14
width permitted will result in an increased load on the sewer pipe. If slopes
are allowed to extend below this level, or if the width of the trench at this
level is greater than the specified maximum width, additional strengthen-
ing of the pipe is required, and accordingly, wherever such conditions
exist and where the fill on the pipe exceeds 6 feet, the Contractor shall
place a Class C concrete fill between the bottom of the trench and the level
of the intrados of the pipe from the outside of the pipe to the undisturbed
sides of the trench. No payment shall be made for such Class C concrete
backfilling which shall become necessary on account of the Contractor's
operations in excavating trenches of excessive widths below the specified
levels.
The elevations shown on the profiles of the sewers are those of the
flowline of the pipes. In excavating the bottom of the trench in material
other than rock, the Contractor shall allow for the thickness of the pipe
where pipe sewers are installed, and shall shape the trench bottom by
hand to fit the lower section of the pipe, as shown on the Plans, recessing
for the bell holes where the bell projects beyond the barrel of the pipe in
such manner as to relieve the bell of all load. If the bottom has not been
excavated to conform to the outside of the pipes, as shown in detail on the
AM Plans, the backfill necessary to the required grade for the outside of the
pipe shall be made with crushed rock for bedding. Bedding shall have a
minimum thickness of 2 inches beneath the pipe and shall be placed up to
the springline of the pipe. If in the opinion of the Engineer the natural mate-
rial is suitable for bedding, it may be used in lieu of crushed rock. Such
crushed rock where excess excavation occurs,shall be placed at the Con-
tractor's own expense.
If the material in the bottom of the trench is unstable or otherwise
unsuitable for supporting the pipe, the unsuitable material may be exca-
vated as directed by the Engineer. The quantity of such authorized addi-
tional excavation shall be determined by the Engineer and paid for by the
City at the unit price bid for "Class B Trench Excavation. "
Where necessary to protect the labor, the work, or adjacent property
and .in all trenches with vertical sides deeper than 6 feet, the Contractor
shall provide and install shoring. The sides of the trench shall be securely
held by bracing or sheeting of either wood or steel. Shoring shall remain
® in place until the backfill has proceeded to a point where it can be safely
removed. If, in the opinion of the Engineer, damage is likely to result
from withdrawing shoring, it shall remain in place. Payment for all
lumber left in place as ordered by the Engineer will be paid for at the
price bid per MFBM for "Lumber Ordered Left in Trench, " which pay-
ment shall cover the whole cost of furnishing all material, labor, equipment,
H_15
tools and all other incidentals which may be necessary for placing the lum-
ber in the trench. This payment shall not cover the cost of furnishing,
placing and removing lumber used for bracing during construction, which
need not remain in place upon completion of the backfill. Payment for
lumber used as temporary bracing shall be included in the price bid per
cubic yard for "Class B Trench Excavation. "
Payment for trench excavation in rock, including backfill and sur-
plus disposal shall be made at the price bid per cubic yard for "Class A
Trench Excavation. " Payment shall cover the whole cost of furnishing all
equipment, labor, tools, materials and all other incidentals which may be
necessary for completing the excavation. It shall cover the whole cost of
rerouting all storm water or sanitary sewage flows, of protecting adjacent
improvements, maintaining temporary macadam or gravel surfaces in
satisfactory and safe condition for use by traffic until permanent pavement
restoration is carried out, and of cleaning up the site.
Payment for Class A trench excavation shall be for the volume cal-
culated on the basis of the payline width of the trench, as herein specified
for the various sizes of pipe sewers, the actual depth of rock removed or
the depth from the upper rock surface to an elevation 6 inches below the
required bottom of the pipe, whichever is the lesser, and the actual length
of rock removed, up to the distance between centers of manholes.
Payment for Class C concrete is covered in Section II, paragraph 15.
Payment for Class B trench excavation, including backfill and sur-
plus disposal, shall be made at the price bid per cubic yard for "Class B
Trench Excavation" (including backfill and surplus disposal). Payment
shall cover the whole cost of furnishing all equipment, labor, tools, mate-
rials and all other incidentals -which may be necessary for carrying out
the necessary excavation, pumping and fluming, and taking care of dry
and storm water flows, protecting adjacent improvements, backfilling,
including tamping of the backfill as herein specified, maintaining temporary
macadam or gravel surface in satisfactory safe condition for use by traffic
until the permanent pavement restoration is carried out, disposing of the
surplus excavated materials, removing any existing sewers, and cleaning
up of the site, including the furnishing, placing and removing of all sheet-
ing and bracing which may be necessary during construction, but which is
not ordered left in place and which is removed as the backfill is being car-
ried out.
Payment for Class B trench excavation shall be for the volume cal-
culated on the basis of the payline width of the trench as herein specified
II-16
for the various sizes of pipe sewers, the actual depth of Class B material
removed, or the depth from the surface to the pipe flowline, whichever is
lesser, and the length between centers of manholes.
Payline widths for trench excavation for pipe which are to be used
in calculating the volume of excavation performed under this Contract are
as follows:
Size of Sewer in Inches Payline Width of Trench
8 - 12 2 feet - 4 inches
15 2 feet - 8 inches
18 2 feet - 11 inches
21 3 feet - 3 inches
24 3 feet - 6 inches
27 3 feet - 9 inches
30 4 feet - 1 inch
36 4 feet - 8 inches
14. STANKS OR SHORT TUNNELS:
The gravity sewers shall be constructed in stanks or short tunnels
where requested by the Contractor and approved'by the Engineer.
The top of the tunneled length shall slope upwards to each entrance
to permit adequate backfilling. The tunneled portions shall be sufficiently
large to allow adequate working room at the sides and above the pipe to be
installed.
FA
The tunnel bottom small be shaped as nearly as practicable to the
bottom of the pipe with provision for pipe bells. A bedding of crushed
limestone and screenings shall be placed to fill any irregularities in shaping
and to ensure a uniform continuous bearing for the pipe barrel at the re-
quired elevation without load on the pipe bells. After firmly bedding and
jointing the pipe, the crushed limestone and screenings shall be solidly
packed around the pipe to the level of the top of the pipe. The remaining
space above the top of the pipe shall be packed solidly with tamped earth
free from debris, rocks, lumps or organic matter or, at the election of
the Contractor, with tamped limestone screenings or compacted sand-
' cement mix.
The Contractor shall carry out the work of stanking in a safe, pru-
dent manner to avoid endangering human life or property.
II-17
No separate payment for the construction of the gravity sewer in
stanks or short tunnels shall be made. Payment for such stanks or short
tunnels shall be considered as included in the price bid for "Class B
Trench Excavation. "
15. CONCRETE BEDDING:
Concrete bedding shall be placed beneath and up to the springline
of all pipes where the bottom of the trench is rock, unless the pipe is to
be encased as shown on the Plans, or where directed by the Engineer.
Class C concrete shall be used for bedding. Concrete bedding shall be
placed only in dry trenches. Backfill above the concrete shall be placed
as stated in Section II, paragraph 21.
Payment will be made for Class C concrete used in bedding in rock
trenches at the price bid per cubic yard for "Class C Concrete. " Such
payment shall cover the whole cost of furnishing all materials, labor,
equipment, tools, and all other incidentals which may be necessary for

16. INSTALLATION OF VITRIFIED CLAY AND CONCRETE SEWER PIPE:
Each pipe shall be set on end and rung before laying and any pipe
found to be cracked or damaged shall be plainly marked in such a manner
that the marking will not rub or wash off, and shall subsequently be removed
from the site.
II-18
Pipe shall be laid with the bell or socket uphill to the line and grade
given by the Engineer on a prepared subgrade excavated and shaped as
hereinbefore described. The prepared subgrade shall be kept free from
water during the laying of the pipe. Line and grade shall'be maintained
by the use of no less than three batter boards set at 25-foot intervals and
a top line. Except by special permission of the Engineer, no pipe shall be
laid except in the presence of an inspector. Each pipe as laid shall be
plumbed for line with a plumb bob, and graded with a grade stick for ele-
vation, The accuracy of the finished line and grade of the pipe shall be
obtained in the preparation of the subgrade.
As the work progresses, the interior of the sewer shall be cleaned
of all dirt or debris of any description.
Pipe shall be laid through line manholes, and the upper half re-
moved after the invert is completed, unless half-pipe is used.
For reinforced concrete pipe, the gasket shall be a continuous
rubber ring and shall be the sole element depended on to make the joint
watertight. Gaskets shall be properly placed on the clean spigot end of
the pipe with the proper adhesive. Before assembly or sending "home"
the pipe in the trench, the exposed gasket surfaces shall be coated with
lubricant. No petroleum product shall be used as a lubricant.
For vitrified clay pipe, the pipe shall be, so handled and stored that
the jointing material will not be deformed or damaged. The joints shall
be connected by first brushing the proper lubricant sealer on the clean
mating surfaces as recommended by the pipe manufacturer. The spigot
end shall be centered on grade into the bell end of the downstream pipe
and shoved "home. " The pipes shall be joined not later than five-minutes
after the application of the lubricant sealer,
All sewer pipe shall be laid and handled so that the allowable*leak-
age shall not be exceeded as measured by the tests hereinafter described.
All extraneous material shall be removed from the completed sewer
pipes and manholes before they are accepted by the City.
All vitrified clay pipe and concrete sewer pipe will be measured
and paid for as such except where it is noted on the Plans that the pipe is
to be included with the lump sum bid for a structure. Each size of pipe
shall be measured and paid for at the corresponding unit price bid for each
particular size and type of 'pipe installed. The length of pipe shall be the
11-19
r
horizontal distance between the centers of manholes as measured along the
alignment of the pipe.
The unit prices for vitrified clay pipe and concrete sewer pipe of
the various sizes and types shall include all material, labor and equipment
necessary to install and test the pipe, complete in place, in accordance
with the Plans and specifications.
17. INSTALLATION OF WYE JUNCTIONS:
Wyes shall be installed in the same manner as specified for the pipe.
Wye branches shall be closed at the outer end. A clay or concrete stopper
or cap shall be placed against the shoulder or offset in the bell, groove or
sockets. The space in the socket above the cap shall be filled with wet sand
or .clay and then covered with a thin coating of mortar so the cap is sealed
but can be readily removed.
Wyes will be paid for at the unit price bid for each and as an addi-
tion to the amount paid for the completed pipe s ewer containing the wye.
The payment shall include all material, labor, and equipment necessary to
install the wye including the stopper or cap.
18. CONCRETE ENCASEMENT:
The pipe shall be encased where shown on the Plans or where
directed by the Engineer with Class B concrete of the dimensions shown
on the detail on Sheet 10. The concrete may be placed against the undis-
turbed earth sides and bottom of the trench. Side forms may be used if
necessary and if approved by the Engineer. Horizontal joints will not be
permitted in unreinforced encasement. Pipe shall be supported and held
in place before and during placing of concrete. The trench shall be kept
dry and free of water until the concrete has set and can not be damaged
by water. Backfill above the top of encasement to a level one foot above
the top of pipe shall be carefully compacted select job-excavated material.
This compacted backfill below a level one foot above the pipe shall not be
placed until 12 hours after the concrete encasement has been completed.

19. MANHOLE CONSTRUCTION:
Manholes shall be built of brick to the dimensions and at the loca-
tions as shown on the Plans or as directed by the Engineer, as rapidly as
the construction of the sewer will permit. All bricks in each course shall
be headers and break joints with those in the adjoining course. Each brick
shall have full mortar joints on the bottom and sides, which shall be formed
at one operation by placing sufficient mortar on the bed and forcing the
brick into it. Horizontal joints shall not exceed 3/8 inch and vertical joints
on the inside of the manholes shall not exceed 1/4 inch:
The mortar for the brick work of the manholes shall be made of one
part of portland cement and three parts of sand, complying with the fine
aggregate specifications hereinbefore described. The sand and cement
shall be thoroughly mixed dry, and the necessary quantity of clean water
shall be added so as to produce a stiff mortar of the proper consistency,
which mix shall be thoroughly worked with proper tools.
All joints on the inside of the manholes are to be carefully rubbed
full and struck as the manhole is built up. Upon completion of each man-
shole, all waste mortar and debris shall be immediately removed from the
bottom and the invert shaped to the dimensions shown on the Plans and all
bottom joints struck or pointed. The jointing of the brick work shall be
such that the manhole will be watertight so that no ground water infiltration
through the manhole joints will occur. The outside of the manhole shall be
covered with a mortar plaster coat 1/2 inch thick.
A single rowlock shall be turned over all incoming and outgoing
pipes,
H-21
rThe inverts of all manholes located at changes in alignment of the
sewer shall be shaped to the incoming and outgoing pipes and smoothly
curved from pipe to pipe to the top of invert at springline.
On line manholes, pipe shall be laid through the manhole and the
upper half removed after the invert has been completed. Half pipe may
be used.
As alternates, precast manholes or manholes built of poured in
place Glass A concrete may be used. Joints of precast manhole sections
shall be formed entirely of concrete employing a rubber gasket conform-
ing to ASTM Designation 0443. Joints shall be self-centering. The gasket
shall be the sole element utilized in sealing the joint. Plans for concrete
manholes must be approved by the Engineer. Forms may be of steel or
clean lumber, assuring a smooth finished surface.
During the construction of each manhole, cast-iron steps conform-
ing to the specifications for cast-iron manhole steps hereinbefore described,
shall be set in place on the inside of the manhole, at the spacing shown on
the Plans. The top step shall not be more than 2 feet below the top of the
manhole. The ends of the steps shall be firmly built in the wall, allowing
the steps to project S inches from the inside of the manhole. Where shown
on the drawings, manholes shall be built over existing sewers and the ex-
isting sewer plugged. The sewers requiring plugging will be filled with
concrete for a length of not less than 2 feet.
Manholes shall be covered with standard cast-iron frames and
covers of the dimensions and materials herein specified. Frames shall
be set in place and closed with covers.
Where manholes are to be constructed on existing sewers, the sew-
age flow shall be diverted to prevent its entry into any new construction
until this construction has been completed to the satisfaction of the Engineer.
All manholes will be measured and paid for as manholes of the ap-
propriate depth as bid in the Proposal.
The depth of manholes shall be measured from the invert of the
sewer to the top of the cast-iron frame and shall be paid for at the appro-
priate unit price bid.
Payment for all work included in this paragraph shall be included
in the unit price for the various depth manholes and shall include all neces-
sary labor, material and equipment for constructing the manholes, including
II-22
additional excavation beyond the trench payline width and depth, concrete
base, cast-iron frame and cover, backfilling, diversion of sewage if re-
quired, and all other work necessary to construct the manhole in place.
Outside drops shall be constructed as shown on the Plans. Payment
will be made for completed outside drops as an addition to the payment
made for the completed manhole. Payment will be made for each drop at
the lump sum bid price for each, and shall include all costs bf excavation,
lumber left in trench, concrete or brick masonry, drop pipe, pipe elbow,
jointing, and the additional cost of the pipe junction on the sewer and its
concrete encasement.
20. STUBS IN MANHOLES:
There is shown on the Plans an approximate location of stubs at
manholes to be provided for future connections. The Engineer may change
the location of such stubs and may order additional stubs installed if the
improvements along the line of the work make such changes or additions
necessary. For pipes 21 inches or less in diameter, the stubs shall be
closed with a clay or concrete stopper or cap cemented in place as speci-
fied in Section II, Paragraph 17, Installation of Wye Junctions, so as to
prevent ground-water infiltration through the stub. For pipes 24 inches
and larger in diameter, 4-inch thick temporary brick masonry watertight
bulkheads close to the outer end shall be constructed.
Payment for furnishing the stubs, including stoppers cemented in
place, or bulkheads in place, will be made at the price bid per "Pipe Stub
in Manhole" of the size used. This payment shall cover the whole cost of
constructing, complete in place, the pipe stub and stopper where ordered.
21. TRENCH BACKFILL:
The backfilling of the completed pipe sewers shall commence im-
mediately upon the completion of the sewer, with care being taken that
the operation of backfilling does not disturb the pipe joints. The initial
backfill over and around pipe sewers to the undisturbed sides of the trench
shall be placed in 6-inch layers which shall be thoroughly hand-tamped to
an elevation not less than one foot above the extrados of the pipe. The
material used for this initial backfilling shall be the excavated natural soil
free from all other foreign substances such as debris, rocks, cinders,
ashes, lumps or organic matter. No walking over the completed pipe
sewer will be allowed until the backfill has been carried to at least one foot
above the top of the sewer. In lieu of tamping the backfill, the Contractor
II-23
may, at his own option and at his own expense, complete the backfill to one
foot above the top of the sewer with crushed rock.
Where the Contractor excavates below the planned subgrade for
pipe lines, the over-excavation shall be backfilled with granular material
well compacted in 6-inch layers. Only granular material placed in over-
excavation authorized by the Engineer will be measured and paid for at
the price bid per cubic yard for "Crushed Rock for Subgrade Replacement, "
which payment shall cover the whole cost of furnishing all materials, labor,
equipment, tools and other incidentals necessary to furnish and place the
granular material. The volume to be paid for under this item shall be
limited to the volume computed within the payline widths and for the depths
and lengths as ordered by the Engineer. Crushed rock placed in over-
excavation not authorized by the Engineer shall be included in the cost of
"Class B Trench Excavation. "
Backfilling shall be completed to ensure restoration of the ground
surface to its original condition.
Backfill in open fields may be completed without further compaction
Alk above one foot over the extrados, or without flushing. 'The fill shall be
mounded over the trench to allow for future settlement.
Backfill of the trenches crossing beneath concrete, asphaltic con-
crete or bituminous macadam pavement shall be made with granular mate-
rials. Payment for granular fill will be made at the bid price per cubic
yard for "Granular Backfill" for the volume in place after final compaction.
The volume of granular fill used beneath pavements which are removed and
replaced shall be computed from the actual length of the trench filled, the
payline width and the depth equal to the average distance from road sub-
grade elevation to one foot above the top of pipe.
All surplus excavated material which is not usable for backfill shall
be hauled from the work site.
The cost of all work included in this paragraph shall be included
with the cost of the excavation requiring the Backfilling or filling operation,
except as noted above.
22. ROCK FILL:
A rock fill shall be placed over the pipe where shown on the Plans.
The rock shall be placed in 15-inch lifts in a manner which will not damage
II-24
the pipe or its encasement. Before placing the final lift, the fill shall be
flushed full with a mortar consisting of one part portland cement to five
parts sand. After placing the final lift, which will bring the fill up to
match the original grade, the fill shall again be flushed full of mortar.
All work included in this paragraph shall be measured and paid for
at the unit price bid per ton for "Rock Fill, " which payment shall cover the
whole cost of furnishing all materials, labor, equipment, tools and other
incidentals necessary to furnish and place the rock fill. Payment will be
based upon the actual tonnage of stone placed in the fill.
23. LEAKAGE TESTS FOR GRAVITY SEWERS:
Upon completion of a section of the sewer, the Contractor shall de-
water it and conduct a satisfactory test to measure the infiltration for at
least two hours. The amount of infiltration, including manholes, Y-branches,
and connections shall not exceed 500 gallons per inch-diameter per mile
of sewer per 24 hours. The Contractor shall be responsible for the satis-
factory watertightness of the entire section of sewer and shall satisfactorily
repair all joints or other locations that are not sufficiently watertight.
For making the infiltration tests, underdrains, if used, shall be
plugged and other ground-water drainage shall be stopped to permit the
ground water to return to its normal level insofar as practicable. Allow-
ance shall be made for water which may enter the sewer through pipe
connections and inlets during the infiltration test.
As required, suitable bulkheads shall be installed to permit the test
of the sewer.
Where the ground-water level is less than one foot above the top of
the pipe at its upper end, the sewers shall be subjected to an internal
pressure by plugging the pipe at the lower end and then filling the pipelines
and manholes with clean water to a height of 2 feet above the top of the
sewer at its upper end.
The rate of leakage from the sewers shall be determined by meas-
uring the amount of water required to maintain the level 2 feet above the top
of the pipe for a period of at least 2 hours, commencing one hour after the
pipeline filling is completed.
Leakage from the sewers under test shall not exceed the require-
ments for leakage into sewers as hereinbefore specified.
1 II-25
The Contractor shall construct such weirs or other means of
measurements as may be required, shall furnish water and shall do all
necessary pumping to enable the tests to be properly made.
Should the sections under test fail to meet the requirements, the
Contractor shall do all work of locating and repairing leaks and retesting
as the Engineer may require without additional compensation.
Payment for all work included in this section shall be included in
the payment for pipe in place as herein specified.
24. CONNECTIONS TO EXISTING MANHOLES:
It shall be necessary to make pipe connections from the new sewer
to manholes on an existing sewer. A hole shall be cut in the existing man-
hole wall to permit inserting the pipe at the required flowline elevation,
horizontal angle, and slope, and to allow at least one inch space all around
the pipe for bedding and filling solidly with 1 to 3 cement-sand mortar.
Any necessary revisions to the existing inverts shall be made to provide a
smooth plastered surface for proper channeling of the flow. All connec-
tions shall be temporarily blocked to prevent entry of sewage into the newly
laid sewer unless all construction below the connection in question has been
completed to the satisfaction of the Engineer. Likewise, at manholes
located at the intersection of new and existing sewers, the flow shall be
carried through the common manhole until all construction below the point
of intersection has been completed to the satisfaction of the Engineer. All
bulkheads shall be removed by the Contractor at the time ordered by the
Engineer. No separate payment shall be made for maintaining the flow in
the Existing sewer.
NE
Payment for making the connections to existing manholes shall be
made at the contract unit price bid for each connection. Such payment
shall be full compensation for furnishing all labor, materials, tools and
equipment required to cut the hole, adjust the invert as required, seal
the new pipe in the manhole, temporarily block the flow into the new sewer
and remove the temporary block when so directed.
25. PLUGGING OF 1XISTIN1 SEWERS:
All sewers to be abandoned shall be carefully plugged so as to pre-
, vent the entrance of soil or foreign matter. The plug shall consist of
Class A concrete of at least 24 inches in length or of other►material as
approved by the Engineer.
11-26
Payment for plugging each sewer will be made at the unit price bid
Per "Bulkhead. " This payment shall cover the whole cost of material,
® labor, and equipment necessary to plug the existing sewer.
26. PLACING OF RIPRAP:
Riprap shall be placed where shown on the Plans or directed by the
Engineer to produce a reasonably well-g mXe:d.=axx of stone with the mini-
mum practicable percentage of voids, and a minimum thickness of fifteen
(15) inches and an average thickness of eighteen (18) inches, The material
may be dumped by skip, crane, dragline, clamshell or other approved
equipment, or other methods approved by the Engineer, No hand placing
of.the stone will be required.
All work included in this paragraph shall be measured and paid for
at the unit price bid per ton for "Riprap, " which payment shall cover the
whole cost of furnishing all materials, labor, equipment, tools and other
incidentals necessary to furnish and place the riprap. Payment will be
based upon the actual tonnage of stone placed.
