Sustainability & Engineering : Wesbrook Mall Redesign, Phase 4 Adams, Cyrus; Atkinson, Kris; Chapman, Jeff; Kamal, Firas Mohammed; Simao, Sean; Thompson, Mateo


The fourth phase of upgrades to Wesbrook Mall were designed to integrate both current user demands as well as the changing demands throughout the corridor’s life cycle. Although corridor use is expected to grow substantially from 2021 to 2050, modelling indicates that single-occupancy vehicle use will continue to decline and be offset with an increase in pedestrian, cyclist, and transit use. The design will move forward with the construction of a pedestrian underpass, a dedicated bus lane, a protected bi-directional bike lane, minor storm-water improvements through the implementation of green infrastructure, and the reclamation of the existing roadway structure. Detailed engineering drawings of the proposed upgrades are included in Appendix A. These drawings demonstrate our design rationale and are supported by technical analysis throughout the report. As the corridor is proposed to stay operational whenever possible, consideration of construction feasibility and sequence has been considered as a design objective and is detailed in the Construction Schedule section of the report. The project's tendering is proposed to be scheduled for the beginning of May 2022. The Class A (+/- 5 to 10%) cost estimate for the work is $7,734,959.23 which includes a 10% contingency. The contingency has been applied for the variability in geotechnical conditions and utility relocation as described in the Risk Management section of the report. With consideration to the detailed design outlined in the report, our team would like to make the following recommendations to the client: A survey and mapping of underground utilities, a detailed geotechnical assessment at the location of the underpass, hiring a pilot communications representative, and adopting strict requirements regarding timelines of submittals and milestones. We would be happy to provide some or all these services to the client at an additional cost in accordance with our standard hourly rates and fees.
