BRIEF DESCRIPTION OF WORK

The Regional Municipality of York (York Region) is required to expand and improve the existing York Durham Sewage System (YDSS), in response to the Provincial Bill 23 under the Supporting Growth and Housing in York and Durham Regions Act (Ontario 2022), by implementing the York Region Sewage Works Project, to be delivered in three phases from 2023 to 2041. The Project Report can be accessed via york.ca/SewageWorks. 

Part of that system expansion includes the Primary Trunk Twinning project which involves the twinning of the existing Primary Trunk, an approximately 5.26 km long single trunk sanitary sewer that, originates at the end of York Region’s Southeast Collector (SEC) system and conveys both York and Durham wastewater flows to the Duffin Creek Water Pollution Control Plant (WPCP) (the “Project”). 

The Project will be a significant component of the YDSS and is paramount for, providing capacity and redundancy to the YDSS, reducing the risk of major system failure, increasing resilience, conveyance, pumping capacity, and providing system operational flexibility.

The Project will be delivered using a progressive construction management delivery model with early contractor involvement (ECI). Under this model, a construction manager at risk (the CMAR Contractor) will be retained by the Region early in the design phase of the Project to provide construction management services throughout the preconstruction and design period. For the Primary Trunk Twinning project, the Construction Manager will be a firm that will self-perform the construction of the tunnel and manages sub-contractors who may be needed to support ancillary works.

The CMAR Contractor will provide constructability input during the preconstruction and design phase, including but not limited to, schedule planning, phasing strategies, constructability reviews, alternative construction approaches, risk management, cost estimating, and plan and design reviews.

The Regional Municipality of York (the “Region”) intends to procure the deliverables described in Section A of the RFPQ Particulars (Appendix A) (the “Deliverables”) and has adopted the following process for procuring the Deliverables:

Step 1 – Prequalification of Construction Manager at Risk (“CMAR”) Contractors

Establish a list of prequalified CMAR contractors who are eligible to participate in Step 2 of the process (the “Prequalified CMAR Contractors”)

Step 2 – Competitive Procurement Process 

Invite the Prequalified CMAR Contractors to participate in a formal competitive process for the provision of the Deliverables

This Request for Prequalifications (“RFPQ”) is an invitation by the Region to prospective respondents to participate in Step 1 of the procurement process outlined above.
