Scope of work
Work includes reshaping and grading the land, building retaining walls, creating five drainage ponds, and developing the Park and Ride area and other paved public spaces.
Crews will also install underground infrastructure, including utilities, power and communications systems, drainage networks, and stormwater infrastructure, while relocating or protecting existing services as needed.

August 2026 Update
Construction continues to advance at the future MSF site. Following mobilization in June, crews began removing topsoil and carrying out rough grading work to prepare the site for major construction activities.
Foundation work remains underway, with concrete footing pours continuing across several areas of the facility. As part of this work, anchor bolts supplied through a separate steel contract have begun to be installed in the concrete foundations, helping prepare the site for structural steel installation planned for next year.
Construction of retaining walls is also progressing, with mechanically stabilized earth (MSE) wall excavation ongoing. Work will continue through the fall as foundation construction, retaining wall development, and underground infrastructure activities advance across the site.
