Site work for a water / sewer project in Regina, Saskatchewan. Working plans call for site work for a water / sewer project.

Phase 2 of the South Trunk is nearing completion and consists of a twin 900mm siphon crossing of Wascana Creek, and approx. 700m of 2100mm reinforced concrete pipe installed by open cut construction to a greenspace location approximately 260m south of Dewdney Ave. Contract 3 is the next phase of the project and involves trenchless installation of approx. 1100m of 1980mm inner diameter sewer from the pipe stub, south through Government of Canada Lands, the Royal Regina Golf Course and Rambler Park. The contractors micro tunnelling system shall be a capable of providing full active face support and tunnel support throughout the excavation. The void created by the excavation overcut shall be filled with bentonite as excavation advances. No routine personnel are required within the machine or installed pipe sections. The jacking pipe shall serve as the casing and carrier pipe in a one-pass installation. The project includes construction of sealed shafts, manhole installation, traffic management, and restoration. TIMELINE: The City of Regina is providing advance notice of its intent to release a Negotiated Request for Proposals (NRFP) for construction of Phase 3 of the South Trunk utilizing trenchless construction techniques. Future proponents/contractors should be experienced in the installation of large diameter sewers by trenchless methods. Approved trenchless installation methods will be limited to the use of Pressurized Close Face Micro Tunnel Boring Machines (MTBM) with pipe jacking. *Budget is unreleased.
