Water Mains

7-09.3(10) Backfilling Trenches

Prior to backfilling, form lumber and debris shall be removed from the trench. Sheeting
used by the Contractor shall be removed just ahead of the backfilling.

Backfill up to 12 inches over the top of the pipe shall be evenly and carefully placed.
Materials capable of damaging the pipe or its coating shall be removed from the backfill
material. The remainder of the material shall be placed by dumping into the trench by any
method at the option of the Contractor, and shall be compacted as specified hereinafter.

A minimum 3 inch sand cushion shall be placed between the water main and existing
pipelines or other conduits when encountered during construction.

7-09.3(11) Compaction of Backfill

Backfill shall be compacted to at least 95 percent of maximum density as specified in

Section 2-03.3(14)D

At locations where paved streets, Roadway Shoulders, driveways, or sidewalks will be
constructed or reconstructed over the trench, the backfill shall be spread in layers and
be compacted by mechanical tampers. In such cases, the backfill material shall be placed
in successive layers not exceeding 6 inches in loose thickness, and each layer shall be
compacted with mechanical tampers to the density specified herein. Mechanical tampers
shall be of the impact type as approved by the Engineer.

7-09.3(12) General Pipe Installation

Pipe shall be installed in accordance with the manufacturer’s printed Specifications and
instructions, and to the standards of the AWWA for installing the type of pipe used. The
Contractor shall provide tools and equipment, including any special tools required for
installing each particular type of pipe used.

Short lengths of pipe supplied by the manufacturer shall be used whenever possible to
provide the proper spacing of valves, tees, or special fittings.

7-09.3(13) Handling of Pipe

Pipe shall be handled in a manner that will prevent damage to the pipe, pipe lining, or
coating. Pipe and fittings shall be loaded and unloaded using hoists and slings in a manner
to avoid shock or damage, and under no circumstances shall they be dropped, skidded,
or rolled against other pipe. If any part of the coating or lining is damaged, repair thereof
shall be made by the Contractor at no additional expense to the Contracting Agency
and in a manner satisfactory to the Engineer. Damaged pipe shall be rejected, and the
Contractor shall immediately place damaged pipe apart from the undamaged and shall
remove the damaged pipe from the site within 24 hours.

Threaded pipe ends shall be protected by couplings or other means until laid.

Pipe and fittings shall be inspected for defects.

Rock and Gravity Block Wall and Gabion Cribbing

8-24.4 Measurement

Rock for rock walls and backfill for rock walls will be measured by the ton of rock
actually placed.

Gabion cribbing will be measured by the calculated neat line volume of gabion baskets
in place, using the manufacturer’s stated dimensions.

Gravity block wall will be measured by the square foot of completed wall in place. The
vertical limits for measurement are from the bottom of the bottom layer of blocks to the
