City of Regina Heritage Drainage Upgrades Phase 1 sewer construction

The City of Regina is planning Phase 1 construction for its Heritage Drainage Upgrades project, focused on large-diameter storm sewer installation. - Government buyer: City of Regina, Procurement Branch. - Scope: Approximately 570 m of 1,650 mm storm sewer and 200 m of 1,500 mm storm sewer, primarily installed using trenchless methods. - Work may also include crossings beneath Saskatchewan Drive, limited open-cut construction, shafts, manholes, restoration, and dry pond excavation. - Open-face tunnel boring with pipe jacking is anticipated; other suitable installation methods may be proposed. - Notable requirements: Keep one traffic lane open in each direction on Winnipeg Street and Saskatchewan Drive, use tight shoring for pits and shafts, coordinate around utilities, and monitor vibration and settlement near utilities and structures. Petroleum-hydrocarbon-impacted spoils may require disposal. - OEMs and vendors: None identified. Pipe sizes, lengths, and alignment remain subject to change.

Description

The City of Regina is providing advance notice of its intent to release a negotiated request for proposals for construction of Phase 1 of the Heritage Drainage Upgrade Project using trenchless construction techniques. Phase 1 is anticipated to include approximately 570 metres of 1,650 mm storm sewer and 200 metres of 1,500 mm storm sewer, along with shafts, manhole installation, restoration, and potentially some dry pond excavation. The work may include crossings of Saskatchewan Drive and limited open-cut construction; tight shoring is required for installation pits and shafts, and traffic disruption must be minimized. The contractor should have experience installing large-diameter sewers by trenchless methods, and construction may involve disposal of petroleum-hydrocarbon-impacted spoils.
