When detailed project design occurs parallel to the IA process, the results can streamline construction timelines but introduce challenges for IA decision-making
The Progressive Design Build (PDB) delivery model is gaining popularity in Canada for major infrastructure projects, as a way to manage risk and increase innovation. This approach allows the Contractor to progress design alongside the Impact Assessment (IA) process, support mitigation planning, conduct synchronous permitting, and minimize the duration between the IA decision and construction. However, conducting the detailed engineering design in parallel with the IA process introduces uncertainty in IA planning and delivery. Iterative changes to the project design can change predicted environmental effects and introduce additional approval conditions, creating risks to project schedule. This integrated process presents both challenges and opportunities for the IA to remain robust, feasible, and aligned with regulatory requirements.
This presentation will draw on the practitioner’s experience with the Fraser River Tunnel Project (FRTP) in Metro Vancouver, Canada. FRTP involves an eight-lane immersed tube tunnel, an eight-lane bridge and highway upgrades. FRTP is advancing with a PDB delivery model, in parallel with submission of the provincial IA in 2026. Designated by British Columbia as a ‘key priority project’, FRTP is supported by provincial efforts to expedite authorizations, while collaborating with First Nations, local government, and public stakeholders. This presentation will review learnings associated with IA development for a PDB project and explore opportunities for flexibility with certainty related to concurrent detailed design and environmental management.
