The Municipal Infrastructure Group Ltd., a T.Y. Lin International Company (TMIG), provided a Schedule ‘B’ Class Environmental Assessment, detailed design, inspection, and contract administration for the Keswick South water and wastewater project in Keswick, Ontario, Canada.
The project included 14 watermain valve chambers, 11 forcemain chambers, a siphon, and hydraulic and transient analysis of the forcemains. TMIG also led the detailed design, inspection, and contract administration for the road reconstruction, which included the widening of Woodbine Avenue from a three-lane rural cross section to a five-lane urban/rural cross section.
- TMIG oversaw property acquisition, permits and approvals, utility relocations, and contractor prequalification.
- The watermain included four connections to the existing and future local distribution system, a cut-in connection to the 600-millimeter ductile iron watermain at the reservoir, and a connection to the existing 750-millimeter-diameter plug.
- After poor soils were encountered along two kilometers of the project, a surcharge load program was implemented to induce settlement in the widened sections prior to pavement construction.
- The project included a 10-meter widening of a 21-meter-span bridge carrying a 600-millimeter watermain and two 500-millimeter forcemains across the Maskinonge River.
- To ensure project success, TMIG coordinated closely with all stakeholders, including the Regional Municipality of York, the Town of Georgina, the Lake Simcoe Region Conservation Authority, the Ministry of Transportation, utility companies, and adjacent developers.
