Work under this item shall consist of replacing plastic water service connections with copper water service connections for all connections less than or equal to two (2) inches in diameter. Since the main purpose of this project is to replace the plastic service with copper service line the Contractor may (except for the compression fittings) use the corporation stop as well as the curb boxes, if in good conditions. No need for new taps to the water main and no need for new curb boxes are expected. However, a unit cost has been included in the price table just for the event they are needed due to their condition or if there is leaking. The cost for Trench excavation, pavement removal and backfill, sidewalk removal and backfill, pipe bedding, traffic control, leakage tight testing, trench paving, sidewalk replacement, protection of trees and shrubs and other appurtenant work will not be measured for payment, as it is to be included in the price for the copper pipe.
