Collingwood Water Treatment Plant Expansion
$270,000,000
THE NEW WATER TREATMENT PLANT
expansion on the shores of Georgian Bay
marks a significant milestone for the Town
of Collingwood. The project is expected
to support residential, commercial, and
industrial growth in the community for the
next 25 years or more.
Collingwood took a proactive
approach by pre-qualifying general
contractors early in the design process.
This strategy helped ensure that only
reputable and experienced contractors
would bid on the work. The prequalified
contractors participated in workshops
to discuss contract considerations and
constructability issues, providing valuable
feedback that was incorporated into the
design. The goal is a robust design that
minimizes issues, conflicts, and changes
during construction. •
