The City of Regina is providing advance notice of its intent to release a negotiated request for proposals (NRFP) for construction of Phase 1 of the Heritage Drainage Upgrade Project utilizing trenchless construction techniques. Future proponents should be experienced in the installation of large diameter sewers by trenchless methods. Approved trenchless installation methods are anticipated to make use of Open Faced Tunnel Boring Machine with Pipe Jacking installation but other suitable methods may be considered since means and methods including equipment selection will be the responsibility of the Contractor.
Notable features and constraints of the project include the below:
- Sewer depths varying from approximately 7 to 9 metres below grade;
- The construction will require minimal traffic disruption;
- The Contractor will be expected to use tight shoring for installation pits/shafts to minimize surface disruption. Excavations not using tight shoring methods will not be permitted.
- The construction requires working in the vicinity of high voltage underground electric power, large diameter buried gas mains, buried water mains and sewer mains.
- The construction may include disposal of spoils impacted from petroleum hydrocarbons.
Unless otherwise indicated, and subject to applicable exceptions and exclusions, this procurement is covered by:
Chapter 5 of the Canadian Free Trade Agreement
Chapter 19 of the Comprehensive Economic and Trade Agreement
Article 14 of the New West Partnership Trade Agreement
