The contractor must submit all as-builts for
water/sewer mains and water/sewer services. All costs for as-built
drawings shall be absorbed under various items.
Original site plans may be used in drawing as-builts
for sewer and water mains. The actual pipeline installed shall be
drawn in red pencil or red ink, as will notes and swing ties.
All newly installed water main gate boxes and hydrant
gate boxes must be accurately located and tied off from permanent
building structures only. Ties taken from poles, catch basins, manholes,
other gate boxes, trees and property boundaries are not acceptable.
The above requirement may be modified if any one tie distance is greater
than 100 feet.
Service as-builts must show the exact location and
depths of new water/sewer service in relation to the building that
it services. All depths between the top of the service and existing
ground must be noted.
Water service connection as-builts must include ties
from the building corners to the corporation, the service box, unions,
and any points at which the service changes directions and, in addition,
distances from corporations to curb stops and curb stops to unions
and the point at which the service enters the foundation.
Sewer service connection as-builts must include ties
from the building corners to the tap or wye and to the cleanout and,
in addition, distances from the tap or wye to the cleanout and from
the cleanout to the point at which the service enters the foundation.
The distance from the tap or wye to the upstream sewer manhole in
the public sewer main shall also be noted.
Distances must be accurate to the nearest 10th of
a foot (plus or minus 0.10 inch). Accurate as-built plans are dependent
on good location and measurements prior to backfill.
Before the Town releases final moneys from bid items
or escrow accounts, complete as-built plans must be submitted to the
Department of Public Works, 40 Fordway, Derry, New Hampshire 03038.
