PART 3 - EXECUTION
3.01 Product Marking
Legibly mark pipe at 5-foot intervals and each coupling to identify the nominal diameter, the
outside diameter base, that is, cast-iron or steel pipe (IPS), the material code for pipe and
couplings, the dimension ratio number, AWWA C900, and the seal of the testing agency that
verified the suitability of the material for potable water service (NSF in the United States).
3.02 Delivery and Temporary Storage of Pipe
A. Ship, store, and place pipe at the installation site, supporting the pipe uniformly. Avoid
scratching the pipe surface. Do not stack higher than 4 feet or with weight on bells. Cover
to protect from sunlight.
B. Do not install pipe that is gouged or scratched forming a clear depression.
3.03 Pipe Layout for Curved Alignment
Pipe lengths may be bent for curved alignment but to no smaller radius curve than the following:
Pipe Diameter
(inches)
Minimum Curve Radius
(feet)
4 400
6 600
8 800
10 1,000
12 1,200
3.04 Handling Pipe
Hoist pipe with mechanical equipment using a cloth belt sling or a continuous fiber rope that
avoids scratching the pipe. Do not use a chain. Pipes up to 12 inches in diameter may be lowered
by rolling on two ropes controlled by snubbing. Pipes up to 6 inches in diameter may be lifted by
hand.
3.05 Installing Buried Piping
A. Install in accordance with AWWA C605, Section 02223, and as follows.
B. When installing pipe in trenches, do not deviate more than 1 inch from line or 1/4 inch
from grade. Measure for grade at the pipe invert.
C. Backfill materials in the pipe zone shall be imported sand per Section 02223. Do not add
successive layers unless the previous layer is compacted to 95% relative compaction per
ASTM D1557.
D. Compact material placed within 12 inches of the outer surface of the pipe by hand tamping
only.

AECOM REBID
E. Compact trench backfill to the specified relative compaction. Do not float pipe. Do not use
high-impact hammer-type equipment.
3.06 Assembly of Pipe Joint
A. The spigot and bell or bell coupling shall be dirt free and slide together without displacing
the rubber ring. Lay the pipe section with the bell coupling facing the direction of laying.
B. Insert the rubber ring into the groove in the bell in the trench just before joining the pipes.
First clean the groove. Observe the correct direction of the shaped ring. Feel that the ring is
completely seated.
C. Lubricate the spigot over the taper and up to the full insertion mark with the lubricant
supplied by the pipe manufacturer. If the lubricated pipe end touches dirt, clean the pipe
end and reapply lubricant.
D. Insert the spigot into the bell and force it slowly into position.
E. Check that the rubber ring has not left the groove during assembly by passing a feeler
gauge around the completed joint.
3.07 Wrapping Fittings and Restrained Joint Devices
Wrap buried cast-iron fittings and restrained joint devices with polyethylene per Section 09954.
3.08 Field Hydrostatic Testing
Test pressures are shown in the Piping Schedule in the drawings and/or Section 15144. Test in
accordance with Section 15144.
3.09 Disinfection
See Section 15141 for disinfection of potable water lines. Reclaimed or irrigation (nonpotable)
water are not required to be disinfected.
