GENERAL STATEMENT OF WORK:
The purpose of this project is to rehabilitate deteriorating sanitary pipes and manholes using trenchless methods.
The manholes will be rehabilitated using approved lining methods and materials specified in accordance with the
manhole rehabilitation specifications. The pipes will be rehabilitated using Cured-In-Place Pipe (CIPP). CIPP is a
trenchless rehabilitation method used to extend the service life of deteriorated pipelines without full replacement.
Rather than excavating and removing the old pipe, CIPP installs a resin-saturated liner inside the existing host pipe
which cures in place to form a new, jointless, structurally sound pipe. Minor excavation may be required to install
temporary bypass. Where above-ground piping is not feasible, small trenches (approximately 1 ft x 1 ft to 2 ft x 2
ft) may be excavated. For rehabilitation of pipes larger than 30 inches in diameter, the manhole cone may need to
be removed for liner installation. No new infrastructure will be built with this project and therefore no fill or
significant disturbance will impact existing infrastructure or its surroundings.
ESTIMATED CONSTRUCTION COST:
The estimated cost of construction for this project is between $5,100,000.00 and $5,700,000.00.
