through the pipes both backwards and forwards a double disc or solid or closed
cylinder 75 mm less in diameter than the internal diameter of pipes. The open
end of the incomplete stretch of pipeline shall be securely closed as may be
directed by Owner/Engineer to prevent entry of mud or silt etc.
If as a result of the removal of any obstructions Owner/Engineer considers that
damages may have been caused to the pipelines, he shall be entitled to order the
stretch to be tested immediately. Should such test prove unsatisfactory,
contractor shall amend the work and carry out such further tests as are required
by Owner/Engineer.
It shall also be ascertained by contractor that each stretch from Machinehole to
Machinehole or the stretch as directed by Engineer is absolutely clear and
without any obstruction by means of visual examination of the interior of the
pipeline suitably enlightened by projected sunlight or otherwise.
D.1.17 TESTING AT WORK SITE
After laying and jointing of RCC pipes is completed the pipeline shall be tested at
work site as per the following specifications and as directed by Owner/Engineer.
All equipment for testing at work site shall be supplied and erected by contractor.
Water for testing of pipes shall be arranged by him. Damage during testing shall
be contractor’s responsibility and shall be rectified by him to the full satisfaction
of Owner/Engineer. Water used for test shall be removed from pipes and not
released to the excavated trenches.
After the joints have thoroughly set and have been checked by Owner/Engineer
and before backfilling the trenches, the entire section of the sewer or storm water
drain shall be proved by contractor to be water tight by filling in pipes with water
to the level of 1.50 m above the top of the highest pipe in the stretch and heading
the water up for the period of one hour. The apparatus used for the purpose of
testing shall be approved by Owner/Engineer. Contractor if required by
Owner/Engineer shall dewater the excavated pit and keep it dry during the period
of testing. The loss of water over a period of 30 minutes should be measured by
adding water from a measuring vessel at regular 10 minutes intervals and noting
the quantity required to maintain the original water level. For the approval of this
test the average quantity added should not exceed 1 litre/hour/100 linear
metres/10 mm of nominal internal diameter. Any leakage including excessive
sweating which causes a drop in the test water level will be visible and the
defective part of the work should be removed and made good.
In case of pressure pipeline the completed stretch of pipeline shall be tested for
site test pressure as specified in IS-458-2003. The site test pressure should not be
less than the maximum operating pressure plus the calculated surge pressure, but
in no case should it exceed the hydrostatic test pressure as specified in IS:458
(Latest Edition).
D.1.18 MEASUREMENT
All RCC pipes shall be measured according to the work actually done and no
allowance will be made for any waste in cutting to the exact length required. The
measurement for pipes shall be in running meter nearest to a cm. of length along
the centre line of pipe as actually laid at work sites.
The rate for providing, laying and jointing of RCC pipes shall be deemed to
include the cost of rubber rings, jointing material, testing and extra excavation
required for ordinary bedding of pipes and also for pipe sockets, if any.

All reinforcing bars shall be accurately placed in the exact position shown on the
drawings, and shall be securely held in position during placing of concrete by annealed
binding wire not less than 1 mm. in size and conforming to IS : 280 and by using stays
blocks or metal chairs, spacer, metal hangers, supporting wires or other approved
devices at sufficiently close intervals. Bars will not be allowed to sag between supports
nor displaced during concreting or any other operation over the work. All devices used
for positioning shall be of noncorrodible material. Wooden and metal supports will not
extend to the surface of concrete, except where shown on the drawings, Placing bars on
layers of freshly laid concrete as the work progresses for adjusting bar spacing will not
be allowed. Pieces of broken stone, brick or wooden blocks shall not be used. Layers of
bars shall be separated by spacer bars, precast mortar blocks or other approved devices.
Reinforcement after being placed in position shall be maintained in a clean condition
untill completely embedded in concrete. Special care shall be exercised to prevent any

removed after the concreting has progressed upto a level just below them.
Bars crossing each other, where required, shall be secured by binding wire (annealed) of
size not less than 1 mm and conforming to IS : 280 in such a manner that they do not slip
over each other at the time of fixing and concreting. As far as possible, bars of full length
shall be used. In case this is not possible, overlapping of bars shall be done as directed by
the City Engineer, AMC, Ahmedabad. When practicable, overlapping bars shall not
touch each other, but be kept apart by 25 mm or 1 1/4 times the maximum size of the
coarse aggregates whichever is greater, by concrete between them. Where this is not
feasible, overlapping bars shall be bound with annealed steel wire, not less than 1mm
thickness twisted tight in eight shape around the lapped bars. The overlaps shall be
staggered for different bars and located at fixed locations only along the span where
neither shear nor bending moment is maximum.
