Lean, Innovative, and Unique Project Solutions
The project was constructed during the harsh winter months which complicated concrete placements. The team built tents around the foundations to ensure adequate protection of the concrete and to maintain temperatures for proper curing. Additionally, with the quick thaw, the existing site material became challenging for access. The team utilized crane mats and stone pads to install equipment.
