O...mer, or by changes ordered in the i'lork, or by strike, fire
unusual delay in transportation, unavoidable casualties or
other causes beyond the Contractor's control, or by any cause
which e1e Engineer shall decide to justify the delay, then the ,
time of completion shall be extended for such reasonable time
as the O\.mer may decide i and the decision of the O\.mer shall be
binding on both parties and shall not be arbitrary or unreason- -
able. No such extension shall be made for delay unless claim ~
therefore is made in \.;riting to tl1e Engineer \.,ithin seven (7)
days after the period of delay shall have cOITmenced. The Con-
tractor shall not be entitled to extension of time for each one ~
of several causes of delay operative concurrently, but only for ~
the actual period of delay, nor shall the Contractor be entitled
to an extension for causes of delay if one of such causes for ~
which extension is authorized above. The Contractor shall have .
no claim for damages against the O\vner for delay in performance -
of the contract due to any act or omission of the O\Yners or any ,
of its representatives, and his sole remedy on account thereof I
shall be his right to apply to L~e Engineer for extension of L

Engineer as provided in the Specifications.
The Contractor shall give the Engineer sufficient notice as
required of his need for the establishment of line and grade
so that the Engineer may have time to provide the same. After
lines and grades for any part of the work have been given by the
Engineer, the Contractor wil1 be held responsible for the proper
-10- Sc-ss
execution of the work to such lines and grades and all stakes
or other marks given shall be protected and preserved by him
until he is authorized to remove them by the inspector. The
Contractor shall[ at his own expense, correct any mistakes that
may be caused by their unauthorized disturbance or removal.
The Engineer may require that work be suspended at any time when,
for any reason[ such marks cannot be properly followed. Grade
stakes in sufficient quantities and of a shape and length approved
by the Engineer shall be supplied by the Contractor.
No additional compensation shall be allowed the contractor for
any claims of crews being held up because of lack of line and
grade stakes.
8. EXCAVATION AND PREPARATION OF TRENCH
The trench shall be dug only so far in advance of the pipe line
as the Engineer shall permit. The sides of the trench shall
be sloped and/or braced and the trench drained so that workman
can work safely and efficiently. All work must be done in a
dry trench and no water will be permitted to discharge down
the pipe previously laid without written permission of the
Engineer. It is essential that the discharge of pumps be laid
to natural drainage channels or to drain sewers.
Care must be taken to avoid over-excavation. Should any over-
excavation exceeding two (2) inches be encountered, the material
added shall be moistened and compacted to the satisfaction of
the Engineer, or foundation material shall be added at the ex-
pense of the Contractor. The finished subgrade shall be pre-
pared accurately by means of hand tools.
In all cases where the sewer alignment is located so that space
and access is very limited with respect to the safety and welfare
of adjoining buildings, such as a property line between houses,
the Contractor shall discontinue open trench excavation and
shall jack the pipe in place for.-an adequate length to safequard
settlement and damage to these adjacent structures at no extra
compensation.
The trench width at the top of the excavation may vary depending
upon the depth of the trench and the nature of material encoun-
tered .' The width of the trench shall also be kept at a minimum
to prevent excess destruction of the existing street or highway
pavement.
The trench bottom shall be brought to grade to provide a uniform
and continuous bearing and support for the pipe on solid and
undisturbed ground at every point between bell holes.
-11- SC-SS
When the bottom at sub-grade is soft and in the opinion of the
Engineer cannot support the pipe, a further depth and/or width
shall be excavated and refilled to pipe foundation grade as
required under the above paragraphs, or other approved plans
shall be adopted to assure a firm foundation for the pipe. The
class or type of material which is to be used for refilling up to
pipe grade shall be foundation material as specified in
Paragraph SA (15 ) of these Specifications.
The rough sub-grade beneath the pipe shall be finished to within
0.25 feet of a straight line between pipe joints or batter
boards, and all tolerances shall be above the specified grade.
A string line shall be set to check the line and grade on all
excavation and pipe laying.
Ledge rock, boulders, and large stones shall be removed to pro-
vide a clearance of at least six ( 6) inches but not exceeding
twelve (12) inches below the outside barrel of pipe, or fittings,
and allow a clear width of six (6) inches on each side of all
pipe and appurtenances with ~" additional clearance for each
foot of depth over 15 feet.
The space between the bottom of the trench in rock and the bottom
of the pipe shall be backfilled with suitable material in three
(3) inch uncompacted layers and thoroughly tamped. Generally
speaking, the material shall be specified bedding material. No
additional compensation for placing or tamping this material
I shall be allowed.
I
All excavation shall be unclassified, and no extra compensation
shall be allowed for rock, clay or hardpan even though it may be
advantageous to use explcsives for their removal.
Blasting the excavation will not proceed until the Contractor has
notified the Engineer of the necessity to do so. This notifica-
tion shall in no manner relieve the Contractor of the hazard and
liability contingent on blasting operations. The hours of blast-
ing will be fixed by the Engineer.
Any damage caused by blasting shall be repaired by the Contractor
at his expense. The Contractor's methods of p~ocedure relative
to blasting shall conform to local and State laws and municipal
ordinances.
All excavated material shall be piled in a manner that will not
endanger the work and that will avoid obstructing sidewalks,
driveways, and fire hydrants, and will not cover lawns. Gutters
shall be kept clear or other satisfactory provisions made for
street drainage at all times.

9. SHEETING AND BR~CING
The Contractor, to prevent the disturbing or settlement of adja-
cent road surfaces, foundations, structures, utility lines or
railroad tracks, shall furnish and place all sheeting and bracing
necessary for good working conditions acceptable to the Engineer,
and to prevent damage and delay to the work. The contractor
shall be responsible for the strength and sufficiency of all
sheeting and bracing. All sheeting and bracing shall be placed
at the Contractor's expense.
Any damage to the work under this Contract or to adjacent struct-
ures or property caused by settlement, water or earth pressures,
slides,caves or other causes due to failure or lack of sheeting
and bracing or bracing or improper bracing or through negligence
or fault of the Contractor in any manner shall be repaired by the
Contractor without delay at his expense.
Should the Engineer decide that the sheeting and bracing at any
point is inadequate or improperly constructed, he may order
additional sheeting and bracing to be placed at the Contractor's
expense.
Bracing shall be so arranged as to provide ample working space,
so as not to interfere with the work, and so as not to place
any strain on the structures being constructed, until such
structures are, in the opinion of the Engineer, of ample strength
to withstand such strain. All sheeting and bracing, unless
otherwise specified or ordered to be left in place by the Eng-
ineer, shall be installed and removed from the work at no addi-
tional compensation. No sheeting and bracing shall be removed
until the construction has proceeded far enough to provide ample
strength in the opinion of the Engineer.
Sheeting or bracing may be left in place in the trench at the
discretion of the Engineer. Any sheeting or bracing left in
place shall be cut off approximately 10 feet. from the surface
and the cut-off portion removed, unless the Engineer gives written
permission to leave it in place.
The Contractor shall receive no compensation for sheeting and
bracing left in place.
Where the trench is not located near existing utilities, build-
ings or other structures and where water and other conditions
permit, the Contractor may, with the approval of the Engineer,
omit sheeting and bracing of the excavation. In this event, he
shall excavate a trench of sufficient size to provide adequate
space for the construction work so as to prevent sliding or cav-
ing of the banks into the area within the lines of structures.
-13- sc-ss
10. PILING
The Contractor shall furnish, place, and drive piles as directed
by the Engineer. All piling shall be driven to substantialre-
fusal as defined by M.H.D. Specification 2452.3. Piles shall be
driven vertically in exact position at locations given by the
Engineer. Piles which may become shifted, must be removed and
good piles driven in their places, or additional piles put in
as directed by the Engineer without additional expense to the
Owner. Piles shall be battered when so directed by the Engineer
at no additional compensatiDn.
11. TEt1PORARY BRIDGES AND CROSSINGS
The Contractor shall construct and maintain temporary bridges
and crossings, complete with flagmen, whenever necessary to
expedite the work or to maintain traffic. Temporary bridges
or.: crossings shall be of ample size to safely carry the load
which comes upon them. The cost of all labor, materials, tools,
and equipment.for temporary bridges and crossings shall be borne
by the Contractor, and no separate or additional payment will
be made.
12. LAYING OF PIPE
Proper implements, tools, and facilities satisfactory to the
Engineer shall be provided and used by the Contractor for the
safe and convenient prosecution of the work.
Pipe and materials shall be unloaded and distributed on the job
I in a manner approved by the Engineer.. In no case shall mater-
I
ials be thrown or dumped from the truck.
Before lowering and while suspended, the pipe shal1 be inspected
for defects to detect an" cracks. Any defective, damaged or
unsound pipe shall be rejected.
All foreign matter or dirt shall be removed from the inside of
the pipe before it is lowered into its position in the trench,
and shall be kept clean by approved means during and after lay-
ing. All openings along the line of the sewer shall be securely
closed as directed, and in the suspension of work at any time,
suitable stoppers shall be placed to prevent earth or other sub-
stances from entering the sewer.
Pipes shall be laid to a true line and at uniform rates of grade
between manholes as shown on the Plans. Fine grading, to the
bottom of the barrel, shall proceed ahead of the pipe laying,
and should any over-excavation exceeding two ( 2) inches be en=
countered, the material added shall be moistened and compacted
to the satisfaction of the Engineer, or foundation material
shall be added at the expense of the Contractor.
Holes shall be dug for the pipe bells, and the material placed
at the middle of the preceding pipe laid. The pipe shall be
supported for the bottom 90 degrees and throughout its length
-14- SC-SS
(except for the minimum distance necessary at the bell 11,.
as shown on the Plans. Bell holes shall be adequate to ma,.
the joint, but no larger than necessary so that maximum supp~,
on undisturbed ground will be provided for the pipe.
The bedding of all pipe shall be Class "C" unless specified
or detailed otherwise.
Class "C" bedding is the method of bedding pipe shown on a
Detail Plate in these specifications.
Pipe laying shall proceed upgrade with the spigot ends pointed
in the direction of flow. No pipe shall be laid in "vater or
when the trench conditions are unsuitable for such work,
except by written permission of the Engineer.
The Contractor shall make all connections of pipe to the man-
holes \vhich have previously been constructed. He shall re-
ceive no extra compensation for connection to capped stubs
or cutting into present manho:es. For completing drop sec-
tions for drop manholes, the Contractor shall be paid as per
unit price bid.
If the Engineer considers pipe, as shovm on the plans, is not
sui table for -the subgrade soil condition, he may order the
Contractor to install cast iron, or ductile iron pipe in
lieu of other pipe to be placed on rock stabilized subgrade
or on piling.
13. BACKFILLING AND GRADING
All excavation in trenches shall be backfilled to the original
ground surface or to such grades as specified or shown on the
drawings. The backfill shall begin as soon as practical
after the pipe has been placed and shall thereafter be
carried on as rapidly as the protection of the balance of the
work will permit.
Complete cleanup shall proceed directly behind the backfill-
ing to accommodate the return to normal conditions. Should
the Contractor, in the Engineer's opinion, f.ail to dili-
gently pursue the backfilling and cleanup, the amount of
work on which complete cleanup has not been accomplished
shall be limited to 1,000 lineal feet for the entire job.
The Contractor shall have sufficient equipment on the job to
assure timely backfill and cleanup at all times.
Backfilling and compacting shall be done as thoroughly as
possible so as to prevent after settlement. Depositing of
the backfill shall be done so the shock of falling material
will not injure the pipe or structures. Grading over and
around all parts of the work shall be done as directed by
the Engineer.

Succeeding layers of backfill may contain coarse materials,
but shall be free from pieces of rock, frozen material, con-
crete, roots, stumps, tin cans, rubbish and other similar
articles whose presence in the backfill, in the opinion of
the Engineer, would cause excessive settlement of the trench
or damage to the pipe.
Wherever select material, that exists in pla~e in the upper
four (4 ) feet of the finjshed grade of the paved or travelea
portions of the street of roadway, is removed by the trench
excavation, the Contractor shal1 replace said material (or
material of equal quality) as backfill in the upper four (4)
feet of the finished grade. where select material does not
exist in place as described above, the Contractor shall pro-
vide and place sufficient select backfill to stabilize the
finished grade from surplus material obtainable from other
excavation on the project, within a haul distance of two (2)
miles one way at no additional compensation.

16. SERVICE CONNECTIONS
It shall be the duty of the Contractor to keep an accurate
record of service connections as to location, depth to top
of connection, type of connection provided, etc. Location
shall be made in respect to the survey line stationing, and
house corners or lot corners. This record shall be kept
jointly by the Contractor and the Inspector.
A. RISERS
Risers are to be constructed as shown on the detail draw-
ings on the Plans at all points where the depth of cover
over the invert of the sewer line is twelve (12 ) feet or
more as determined by the Engineer.
B. HOUSE SERVICE CONNECTIONS
At all points designated by the Engineer, the Contractor
shall construct services for house connections, and shall
extend such connections to the property line, unless
otheTIvise indicated on the Plans. The Contractor shall
also coordinate with the Engineer and Surveyor the loca-
tion and invert of all house services.
House Connections shall be kept to a minimum depth of
ten (10 ) feet in the street and not less than nine (9)
feet at the property line, unless otherwise directed by
the Engineer. Services shall be at right angles to the
main sewer unless otherwise directed.
i
All house connections shall be capped, sealed firmly in
place, or by other methods approved by th~ Engineer,
which will effectively prevent water from entering the
sewer until the connection is placed in service.
The Contractor shall provide all necessary wyes or tees
for connecting services to sewer lines at the Contract
Unit Prices. Six (6 ) inch bends shall be provided
to bring services to proper location and elevation, at no
additional compensation.
At the end of all house connections, located at the

no additional compensation, a 2-inch by 2-inch long
wooden stake, set vertically from the service pipe to
the ground surface. In undeveloped areas this stake
shall extend within six ( 6) inches of the ground sur-
face. The Contractor shal1 measure to the nearest
tenth of a foot the depth from the invert to top of stake
and notate same on cut sheet.
17. MANHOLES M~D CATCH BASINS
Excavation shall be to a depth and size to provide for con-
struction of the manhole or catch basin as shown in detail
on the Plans.
-20- Sc-ss
Concrete base shall be of size and depth as shown on the Plans.
Concrete used shall have a 28~day comprehensive strengthof'..at
least 3,000 pounds per square inch. Material used for this
purpose shal1 be subject to the approval of the Engineer.
Base shall be poured on undisturbed earth. Walls shall be
of a precast concrete as shown on the Plans, and shall be
neatly grouted to form a completely watertight manhole.
Precast concrete bases may be used when approved by the Engi-
neer. Precast base must be placed on a minimum of 6 inches
of granular material which has been thoroughly compacted and
leveled off across the entire width of the base.
Frames and covers shall be set to the designated elevation in
a full mortar bed.
The Contractor shall provide a minimum of 611 and a maximum of
18" of sewer brick or precast concrete adjusting rings be-
tween the cast iron frame and the manhole top section or pre-
cast catch basin section. Each ring or brick shall be set in
a full bed of mortar and shall be made watertight. vJood or
other foreign material will not be allowed. Adjusting rings
shall conform to the size and shape of the casting frame.
The bottom of all manholes shall be shaped to conform to the
pipe as shown on the detail drawings, so as to allow a free,
uninterrupted flow of sanitary sewage, or storm water. The
bottom of all catch basins shall be shaped so that all water
will flow into the discharge pipe.
The Contractor, with the approval of the Engineer, where
standard manhole sections cannot be used, as in junction and
transitional manholes, may construct such sections of brick,
manhole block, or concrete or a combination of such materials
set on a concrete base.
Clay sewer pipe shall be laid continuously through the
manholes and shall be broken out when the manhole base is
finished.
Where the foundation is unstable, the Engineer may order the
Contractor to install manholes on piling. Manhole base
reinforcement and timber piles shall be as shO',^ln on the
detail drawings.
18. INFILTRATION ill~D INSPECTION - SANITARY SEWER
Upon completion of the sewer construction and before any
house services are connected, leakage tests shall be made
to determine the amount of ground water infiltration into
the sewers. Measurements will be taken by means of 90-
-21- Sc-ss
degree V-notch weirs placed i.n the lines. Measurements shall
be taken at all points where! in the opinion of the Engineer,
the flow of the water in the sewer is greater than the maxi-
mum allowable leakage. The maximum allowable rate of leakage
for any section of sewer shall be 100 gallons per inch of
internal pipe diameter per mile of pipe per 24 hours (15
gallons per 24 hours for 9 inch pipe.)
In case measurements indicate a leakage greater than the maxi-
mum allowable leakage, additional measurements shall be taken
and continued until all leaks are located and the necessary
repairs and corrective work have reduced the leakage in the
section being tested below the maximum allowed by the speci-
fications. All repair work and materials used must be
approved by the Engineer. For purposes of the test, the line
between adjoining manholes will be considered a section and
will be tested as such.
The Contractor shall furnish the weirs and other material and
labor for placing the weirs in the sewer and shall assist the
Engineer in making measurements. The Contractor shall receive
no additional compensation for making the leakage tests or
corrective work necessary to reduce leakage below the maximum
allowed by the specifications.
In addition to the infiltration test, exfiltration tests will
i be required on sewer lines which are above the present ground
water.
The test section shall be bulkheaded and the pipe subjected
to a hydrostatic pressure produced by a head of water at a
depth of four ( 4 ) feet above the bottom invert of the sewer
under test at its lower end. This head of water-shall be
maintained for a period of one hour during which it is pre-
sumed that full absorption of the pipe body has taken place,
and thereafter for a further period of four (4 ) hours for
the actual test of leakage. During this four (4 ) hour
period, the measured loss shall hot exceed that specified for
infiltration.
The introduction of any substance into the water used for
testing with the intent to seal such leaks as may be indicated
will not be permitted.
Two such exfiltration tests will be required for each type of
pipe and for each size of pipe. If the results are satis-
factory on the two sections chosen by the Engineer, no further
exfiltration tests will be required.
If_results of the exfiltration test are not satisfactory,
-22- Sc-ss
additional tests may be required until the Engineer is satis-
fied fhat the leakage requirements are being met.
Prior to final acceptance of each section of the sewer line,
the Contractor shall flush a ball, the full diameter of the
sewer, through the line. All dirt and debris shall be pre-
vented from entering the existing sewer system by means of
watertight plugs or other suitable methods.
Upon completion of the Contract, the Engineer will carefully
inspect all sewers and appurtenances. Any cracked or broken
pipe shall be removed and replaced with a sound one and the
invert of the sewer shall be left clean and free from any
obstructions throughout the entire line.
19. INTERRUPTION OF PRIVATE WATER SUPPLIES
If any private water supply shal1 become interrupted, either
temporarily or permanently, soleJy as a result of the Con-
tractor's dewatering procedure, the Contractor shall be held
harmless from any claims.
20. DETOURS - TRAFFIC CONTROL
When traffic cannot be diverted, it will be permitted to use
the street at all times.
The Contractor shall furnish sufficient signs to facilitate
the directing of traffic. These signs shall conform to the
signs illustrated on the detail sheets, and placed as
directed by the Engineer. Each detour sign shall be reflec-
torized and shall be illuminated with two six (6) inch,
battery-powered, blinkers with amber lenses. All barricades
shall have blinker lights on each end. The Contractor shal1
have a sufficient number of barricades and signs on hand
prior to the start of construction.
It shall be the Contractor's responsibility to make a check
and inspection of all lights and barricades every four hours,
including Sundays and Holidays. He shall maintain the
streets in a passable conditione He shall conduct his work
so as to create a minimum of inconvenience to traffic and
shall furnish not less than two flagmen at each location
where loading or depositing of material requires the turning
of the trucks on any State Highway or "Main Street" and where
the operation of construction equipment endangers traffic.
Temporary suspension of work does not relieve the Contractor
of the responsibility outlined in the above requirements.
-23- SC-SS
2l. RUBBER-TIRED EQUIP~illNT

Contractor may also leave in place, to be imbedded in the back-
fill of the trench, any sheeting and bracing which he may con-
sider necessary to prevent injury to persons, structures, cor-
porations or property, whether private or public, for which he
assumes the entire and sole liability for any damage which
may be caused by the installation, and for which he shall re-
ceive no payment or extra compensation.
No sheeting and bracing which is within 3 feet of the surface of
the ground may be left in place in the trench without written
permission from t~e Engineer. Wnen sheeting and bracing have
been ordered left in place, payment for same shall include the
upper 3 feet of lIcut-off" section of the sheeting.

cylinder pipe 24 inches in diameter or larger shall be grouted
on the inside at the joint in accordance with manufacturer's
recommendations.
C. Setting Hydrants
Hydrants shall be placed where shown on the plans or where
directed by the Engineer.
Hydrants shall be supported upon a concrete base 18 inches
square and a minimum of 5 inches thick. Each hydrant is to be
braced against the far end of the trench by a suitable concrete
reaction block against the back of the trench.
Hydrants of sufficient length shall be installed as to provide
necessary ground cover as shown on the plans over the top of
the lead pipe and the lowest outlet on the hydrant shall be
not less than 15 inches above the ground line, no more than 24
inches above the ground line.
Wherever a hydrant is set in soil that is pervious, drainage
shall be provided at the base of the hydrant by placing coarse
gravel or crushed stone mixed with coarse sand, from the bottom
of the trench to dt least 6 inches above waste openings in the
hydrant and to a distance of 1 foot around the base elbow.
vmerever a hydrant is set in clay or other impervious soil, a
drainage pit 2 feet in diameter and 3 feet deep shall be
excavated below each hydrant base and filled compactly with
coarse gravel or crushed stone and coarse sand, under and
around the elbow and concrete base to a level of 6 inches above
the waste opening, refer to detail in appendix of these Contract
Documents.
Cover all material placed for drainage with a minimQm of two
layers of tar paper. No drainage system shall be connected to
a sewer.
Hydrants must maintain their position and must not be knocked
out of plumb during backfilling.
D. Valves, Boxes, Manholes, Vaults and Fittings
Valves and fittings shall be placed where shown an the
plans or as designated by the Engineer. Jointing shall be done
as previously specified herein.
Unless otherwise specified or sho\1n on the drawings, cast iron
valve boxes shall be installed with all gate valves 12 inches or
smaller and all butterfly valves and ball valves. Valve
boxes shall be firmly supported to maintain
-17- sc-w
centered and plumb alignment over the wrench nut of the
valve, with box cover flush with the surface of the finished
pavement or at such other level as may be directed by the
Engineer.
All geared valves and such other valves as may be designated
shall be set in masonry valve manholes or vaults with the
wrench nuts readily accessible for operation through the man-
hole openings. Manholes shall be constructed in a manner that
will permit minor valve repairs and to afford protection to the
pipe from impact where it passes through the manhole or vault
walls.
E. Building Services
Curb stops and boxes shall be installed as shown on the detail
plates in the Appendix. The curb stop and box shall be located
on the property line, unless specified otherwise.
Corporation stops shall be tapped into the main only when full
of water under pressure. No taps shall be. made into a dry
pipe. Corporation stops shall be turned into the pipe until
- -- - ...
tight and shall not be turned back to facilitate having the
operating nut on the toP.
.... ,-. .......
The copper service lines as placed between the water mains and
the curb boxes shall have a minim~~ of 7.5 feet of cover;
therefore service lines must be placed (incidental to the
project) beneath any obstruction which would prohibit the
required cover if the service line was placed on top of said
obstruction. Tne method of tQnneling under an obstruction
shall be approved by the Engineer.
17. BACKFILLING AND GRADING
All excavation in trenches shall be backfilled to the original
ground surface or to such grades as specified or shown on the
drai<lings. The backfill shall begin as soon as practical after
the pipe has been placed and shall thereafter be carried on as
rapidly as the protection of the balance of the work will
permit.
Complete cleanup shall proceed directly behind the backfilling
to accommodate the return to normal conditions. Should the
Contractor, in the Engineer's opinion, fail to diligently
pursue the backfilling and cleanup, the amount of work on which
complete cleanup has not been accomplished shall be limited to
1,000 lineal feet for the entire job. The Contractor shall
have sufficient equipment on the job to assure timely backfill
and cleanup at all times.
-18- SC-W
Backfilling and compacting shall be done as thoroughly as pos-
sible so as to prevent after settlement. Depositing of the
backfill shall be done so the shock of falling material will
not injure the pipe or structures. Grading over and around
all parts of the work shall be done as directed by the Engineer.
Granular material, or other suitable material as determined by
the Engineer, free from rocks and boulders, shall be deposited
in the trench simultaneously on both sides of the pipe for the
full width of the trench to a height at least six (6) inches
above the top of the pipe, shovel placed and hand tamped to
fill completely all spaces under and adjacent to the pipe. In
the event that natural, suitable, granular material is not
encountered during the normal excavation of the trench,
or when the material encountered is determined unsuitable by
the Rngineer, for backfilling around the pipe as required above;
the Contractor shall provide and place such approved material.
The Contractor shall furnish approved material from surplus
material obtainable from other excavation on the project, within
a haul distance to two (2) miles one way, at no additional com-
pensation. If suitable material is not available as stated
above, the Contractor shall purchase suitable pit run material
for backfilling around the pipe.
The Contractor shall be paid for only that select material re-
quired for filling or backfilling as he may be directed to pur-
chase and place by the Enginp.er. All quantities of such material
used shall be verified by the Engineer.
Succeeding layers of backfill may contain coarse materials, but
shall be free from pieces of rock, frozen material, concrete,
roots, st~~ps, tin cans, rubbish and other similar articles
whose presence in the backfill, in the opinion of the Engineer,
would cause excessive settlement of the trench, or damage to
the pipe.
Wherever select material, that exists in place in the upper four
(4) feet of the finished grade of the paved or traveled portions
of the street or roadway, is removed by the trench excavation,
the Contractor shall replace said material (or material of equal
quality) as backfill in the upper four (4) feet of the finished
grade. Where select material does not exist in place as des-
cribed above, the Contractor shall provide and place sufficient
select backfill to stabilize the finished grade from surplus
material obtainable from other excavation on the project, within
a haul distance of two (2) miles one way at no additional com-
pensation.
-19- Sc-w
Backfilling shall be done in lifts of uniform layers not to ex-
ceed the depth shown in the compaction chart and each lift shall
be completely compacted over the full width of the excavated
area. Compacting shall continue until no more settlement occurs.
Three feet of material over the top of the pipe shall be re-
quired before a vibratory or sheepsfoot roller may be used.

basins, valve boxes, curb boxes, and other structures, and
utilities by the use of pneQmatic tampers, plate tampers, or
plate vibrators '.'lith lifts not to exceed that shovln in the
COMPACTION CillL~T.
Hydrant leads and water service trenches must be compacted in
the same manner as the water main trenches. They shall not be
left open overnight. ~n areas where curb and gutter exists,
sufficient curbing shall be removed to allow this compaction
over the entire disturbed area.
All deficiencies in the quantity of materia~ for backfilling
the trenches or for filling depressions caused by settlement
shall be supplied by the Contractor. A..l1.y excess suitable material
shall be hauled away and deposited and leveled where directed by
the Engineer at no additional compensation. The haul limit shall
not exceed two (2) miles one way.
No waste material or debris shall be deposited on any public or
private property within the limits of'the municipality without
the written permission of the Engineer. Waste material and
debris shall include, but not be limited to, trees, stumps,
pieces of pipe, pieces of concrete, pieces of asphaltic concrete,
tin cans, or other waste material from the construction opera-
tions. All disposal areas shall be leveled off and the area
shall have approximately one (1) foot of clean fill area on the
top, all at no additional compensation.
-20- SC-W-
vfuen the trench excavation for the water main and appurtenant
work is within the right-of-ways of State or County Highways,
the backfilling of the trench, compaction of materials, sub-
grade preparation and surfacing shall be done in strict accord-
ance with the requirements and specifications of the State or
County Highway Department at no additional compensation.
In all cases, the Contractor shall blade and compact the road-
way after the trench has been backfilled, so that it shall be
passable to traffic at all times. Tne Contractor shall main-
tain the roadway in a condition acceptable to the Engineer at
all times until final acceptance of the entire work by the
~vner. Therefore, the Contractor shall provide one motor grader
which shall be available to the project at all times for surface
maintenance. If, in the opinion of the Engineer, the Contractor
is not maintaining street surfaces sufficiently with one motor
grader, he shall provide additional motor graders.
The Contractor shall also blade and maintain all detours and by-
passes. All maintenance work shall be done at no additional
compensation.
In addition to th8 blading and maintenance requirements speci-
fied, the Contractor shall provide at least one tank truck with
presurized spray bars for spraying water on the streets to
control the dust. Dust control shall be required, as necesary,
on all streets after compact i_on and grading, and on all detours
or by-passes. Payment for dust control shall be as specified in
Article 22, Paragraph O.
The Contractor shall remedy at his Oi~ expense any defects that
appear in the backfill for a period of one year following com-
pletion.
18. TESTING A~ID DISI1WECTING ~ffiINS
After the pipe has been laid including fittings, valves, and
hydrants and the line has been backfilled in accordance with
these specifications, all newly laid pipe, or any valved section
thereof, unless otherwise directed by the Engineer, shall be
subjected to hydrostatic pressure of 150 pounds per square inch.
The duration of each such test shall be at least two hours.
Water added to maintain the pressure shall not exceed the volume
per 100 lineal feet of pipe being tested during the two hour
test as specified in the following table:
-21 SC-W
Maximum Allowable Leakage in
Pipe Size Gallons/100 ft. of Pipe/2 Hour Test
611 0.2 gallon
8 II and 10 II 0.25 gallon
12 II (). 35 gallon
1611 0.50 gallon
Larger than 16'1 .03 gallons/inch of dia.
Each valved section of pipe shall be slowly filled i'lith water
and the specified test pressure, measured at the lowest point
of elevation, shall be applied by means of a pump connected to
the pipe in a satisfactory manner. The pump, pipe connection,
gauges and all necessary apparatus shall be f~rnished by the
Contractor. Gauges and measuring devices must meet with the
approval of the Engineer and the necessary pipe taps made as
directed. Before applying the specified test pressure, all air
shall be expelled from the pipe. To accomplish this, taps shall
be made, if necessary, at points of highest elevations, and
afterward tightly plugged.
Any cracked or defective pipes, fittings, valves or hydrants
discovered in consequence of the pressure test shall be removed
and replaced by the Contractor with sOQnd material in the manner
provided and the test shall be repeated until satisfactory to
the Engineer.
Each house service with the corporation cock open, shall be
tested hydrostatically with a pressure of 150 pounds per square
inch in the water main and service prior to backfilling the
excavation. A visual inspection will be made of each service at
the corporation cock and at the curb stop while the service is
under hydrostatic test. Testing of individual services with
the corporation cock closed 1-fill not be allowed. All house
service-installations shall be completed by 4:00 P.M. each day
to permit testing and backfilling of service connections.
Testing of house services shall be done with a constant pressure
pump to maintain 150 p.s.i. throughout the test.
After the installation has been tested, the Contractor shall
follow the disinfection procedures as described in paragraphs
Nos. 1227 and No. 1228 of Section XII, IIManual of "\>Jater Supply
Sanitationll, of the Minnesota Department of Health. The Con-
tractor shall become thoroughly informed on the requirements
of the above mentioned manual and shall maintain a sufficient
number of copies of same on the job site.
-22- SC-W

Unless facilities are available for the introduction of either
chlorine or heavily chlorinated water directly into the mains
on their completion, chlorine disinfectant should be placed at
each joint prior to jointing. The following table indicates the
amount of calcium hypochlorite (65% available chlorine) that
shall be added to each 20 foot length of pipe to furnish a
solution containing the minimum amount of free chlorine.
Pipe Size Calcium H ochlorite 65% available chlorine
- b II O. oz .
8 II 0.8 oz.
12 II 1.5 oz.
16 II 2.8 oz.
18 II 4.0 oz.
24 II 6.3 oz.
30 II 8.3 oz.
36" 15.0 oz.
Only fresh disinfectants shall be used and the main filled with
water and flushed not later than one week after the disinfectant
has been added. The vlater (containing chlorine) shall be left
in the pipe, being disinfected, for a minimum of twenty-four
(24) hours.
An electrical conductivity test shall be in accordance with
the following procecure.
A. Testing Procedure
a. The system (pipeline and hydrants) shall be testad .or
electrical continuity and current capacity. The electrical
test shall be made after the hydrostatic pressure'::test and
while the line is at normal operating pressure. Backfilling
shall have been completed. The line may be tested in sec-
tions of convenient length as approved by the Engineer.
b. Direct current of 350 amperes, +10%, shall be passed through
the pipe line for 5 minutes. Current flow through the
pipe shall be measured continuously on a suitable ammeter
and shall remain steady without interruption or excessive
fluctuation throughout the 5 minute test period.
c. Insufficient current or intermittent current or arcing,
indicated by large fluctuation of the ammeter needle,
shall be evidence of defective electrical contact in
the pipe line. The cause shall be isolated and corrected.
Thereafter, the sectioh in which the defective test
occurred shall be retested as a unit and shall meet the
requirements.
-23- Sc-w
B. Notes on Test Procedure
a. Sources of D. C. current for these tests may be mdor
generators, batteries, arc welding machines, etc. D. C.
arc welding machines will probably be the usual source.
These machines are available in adequate capacity for
these tests and are equipped with controls for regulating
the current output.
b. Cables from the power source to the section of the system
under test should be of sufficient size to carry the test
current without overheating or excessive voltage drop.
Usuable sizes will probably be in the range of 2/0 to
4/0 A.W.G.
c. Connections for the test shall be made at hydrants. The
hydrants shall be in the open position with the caps on
during the test. The cable shall be clamped to the top
operating nut. Note: After the test the hydrant shall
be shut off and a cap loosened to allow hydrant drainage.
Tighten cap after drainage.
d. A hook-on type D.C. ammeter placed on one of the cables
leading to the hydr~Dt is a convenient method of measuring
cu rrent.
e. In using arc welding machines, the current control should
be set at minimum before starting. After starting the
machine, advance the control until the current indicated
on the arr~eter is at the desired test value. Caution:
In case of open circuits at joints or connections, the
voltage across the defective joint or connection v-lill be
in the order of 50-100 volts.
19. RESTORATION OF GROUND AND ROAD SURFACES
vmerever the surface of the ground is removed or disturbed by
the Contractor's operation the Contractor shall restore, replace
or rebuild all such surfaces to a condition at least equal to
its condition at time of removal. Blading and maintaining of
streets and roadways are covered hereinbefore in these provisions.
If the alignment of the water main and its appurtenances, as
shovffi on the plans, is alongside or parallel to a paved roadway,
but the proximity of such alignment to the paving does not
warrant any damage or removal of such paving, the Contractor
shall replace or repair the paving which he has removed or
damaged at no additional compensation.
-24- SC-W
20. RESTORATION OF SOD, TREES, DRIVEWAYS, CURBS AND SIDEWALK
Any and all curb and gutter or sidewalk disturbed by the Con-
tractor during construction shall be replaced with new curb
and gutter or sidewalk in conformance with the municipality's
standards and with no additional compensation. The replace-
ment shall include the obtaining of line and grade on exist-
ing curb ~Dd gutter or sidewalk and setting of line and grade
at time of replacement.
Any trees which will lie within the limits of the excavation
shall be removed by the Contractor only with the express written
permission of the Engineer. There shall be no additional com-
pensation for the removal of such trees, but the Contractor will
not be required to replace any tree so removed.
Any concrete, blacktop, or crushed rock or other type of drive-
way disturbed by the Contractor during construction shall be re-
placed or rebuilt to a condition at least equal to its condition
at time of removal. There will be no additional compensation
allowed for this item.
Any sod which is disturbed during the installation of water lines
or appurtenances shall be replaced, including the necessary black
dirt. The Contractor will be reimbursed for sodding up to a
maximum of a strip ten (10) feet in width, measured five (5)
feet on each side of the water pipe or service as installed. Any
sod requiring replacement outside the ten (10) foot maximum shall
be replaced by the Contractor at no additional compensation.
Black dirt shall be replaced to a thickness equal to th~t removed
up to a maximum of one (1) foot. No sod shall be laid on
less than four (4) inches of black dirt.
Black dirt shall be light friable loam containing a liberal
amount of humus and shall be free from heavy clay, coarse sand,
stones, plants, roots, sticks, and other foreign materials.
Sod shall be rolled within 2L~ hours after its placement with a
roller that leaves the sod smooth and the joints properly
closed. The new sod shall be trimmed to neatly match old sod,
curbs, and walks.
Sod shall be high quality, cultured, free from weeds, and in a
good healthy condition. Unsuitable sod shall be replaced at no
additional compensation. All sod shall be watered by the Con-
tractor for a period of six weeks after installation.
21. WORKMANSHIP AND CLEAl~P
Upon completion of the contract, the Contractor shall dismantle
and remove all construction plant, equipment, appliances,
barricades and surplus materials; shall clean the sewers and
