SUBJECT: T09-081- Sanitary and Watermain Trenchless Rehabilitation on
Greenbrook Drive (Warren to Birchcliff)
RECOMMENDATION:
That tender T09-081, Sanitary and Watermain Trenchless Rehabilitation on Greenbrook Drive
(Warren to Birchcliff), be awarded to McGillivray & Sons Contractors Limited, St. Agatha,
Ontario at their corrected tendered price of $634,263.61, including provisional items and
contingencies of $147,509. and G.S.T., and further that the Mayor and City Clerk be authorized
to execute an agreement satisfactory to the City Solicitor.
BACKGROUND:
The City of Kitchener Engineering Infrastructure staff has identified that 70.0 meters of sanitary
sewer has been fractured and deformed and is in need of replacement. Also identified within
the same limits of construction is 480.0 meters of cast iron Watermain that is at the end of its' life
cycle and needs to be replaced. In conjunction with same, there are approximately 42 water
services that will be replaced at the same time. All mechanical fittings such as water valves, fire
hydrants and tees will be replaced as well.
The replacement of this infrastructure will be replaced using the pipe bursting method. This type
of trenchless method substantially reduces the amount of open excavation that normally would
be required for this type of work. Also, this method reduces the residential restoration of
properties within the construction limits.
The existing concrete sanitary sewer main will be replaced with high density polyethylene pipe.
The existing cast iron watermain pipe and services will be replaced with high density
polyethylene pipe.
