The city has given the green light to a $3.2 million project to repair a portion of the storm sewer system from the intersection of Black Road and McNab to Boundary and Bennett Boulevard.
“Construction is expected to begin in 2024 and be completed by fall,” said Catherine Tudd, the city’s development manager and environmental engineer. Sue today.
“There will be some lane closures for access, but the road will not be completely closed,” Tad said.
The City Council last week awarded the $2.9 million contract to Insituform Technologies, the lowest of two bidders.
Insituform is based in Edmonton with a regional office in Hamilton.
The bid was 22.7 percent higher than city staff’s estimate, which Tad attributed to rising material costs, limited availability of contractors eligible for specialized work, and the challenges and risks associated with lining large-diameter sewer lines.
The highest bidder was Capital Sewer Services Inc. of Vaughan, Ont., whose $2.96 million bid was revised to $3.06 million.
Insituform was the first company to commercialize Cured-In-Place Pipe (CIPP), a trenchless method of making old pipes like new by installing and curing a resin-containing liner.
“Storm drain rehabilitation with techniques such as CIPP lining and grouting can impact climate mitigation by minimizing soil disruption, reducing carbon emissions, and improving infrastructure resilience.” ” Tad said in his report to Mayor Shoemaker and City Council members.
“Furthermore, these methods contribute to climate adaptation by enhancing stormwater management, reducing flood risk, and promoting longevity of urban infrastructure.”
The South Market project includes the rehabilitation of 610 meters of storm drains with diameters of 1050 to 1950 millimeters with CIPP lining and 460 meters of storm drains with diameters of 1650 to 1800 millimeters with grout injection.
Insituform will use Hamilton-based Empipe Solutions Ltd. as a subcontractor for sewer grouting and the Sault Ste. Marie’s Trimount Construction Group, which constructs and repairs manholes;
