Project Description
Project Scope
Soletanche Bachy Canada was the General Contractor for the rehabilitation of 140 metres of the East Dock Wall at Billy Bishop Toronto City Airport, where the existing structure was reaching the end of its service life.
Solution
Soletanche Bachy Canada constructed a new combi-wall system entirely from marine plant to accommodate limited space and ongoing airport operations.
A value-engineered rock anchor solution was implemented to reduce interference with airport activities and avoid onshore construction. Precast concrete coping units were installed from barges using a controlled concrete placement approach, ensuring quality execution while minimizing waste.

Sustainable development
Soletanche Bachy Canada reduced CO₂ emissions by 36% (105,000 kg) across the concrete-related scopes compared to the project’s original baseline.
A value-engineered design replacing tie-rods and concrete anchor blocks with rock anchors eliminated 23,000 kg of CO₂ emissions.
To further reduce environmental impact, the team used a volumetric concrete mixing truck for the installation of flowable concrete. This approach reduced emissions for this scope by 49%, eliminating approximately 77,500 kg of CO₂ while also minimizing waste and improving quality control.


Project Outcome
This project demonstrates our ability to deliver complex marine foundation works in a highly constrained, live operational environment. By adapting construction methods to limited access, active airport operations, and waterfront conditions, our team delivered a safe, coordinated, and reliable rehabilitation solution from planning through completion.
Key takeaways
- Successful execution in an active airport and marine environment
- Value-engineered solutions that reduced construction risk and environmental impact
- Coordinated delivery despite barge-only access and limited working space
