Load-Bearing Wall Removal in Mississauga: 10th Line W

The 10th Line W, Mississauga project required the removal of the load-bearing wall separating the dining and living rooms, but the structural conditions made this far more complex than a standard main-floor opening. The breakfast area on the main floor did not continue with an equivalent space on the second floor, and the exterior wall above, made of a cinder-block wall with an exterior brick envelope, was offset from the foundation. Even more challenging, that offset exterior wall was sitting on an existing steel beam supported by a steel post hidden inside the wall we needed to remove. This created a unique engineering scenario where the new beam had to safely take over the load path of the existing structural steel.

The structural design called for a 20-ft W8 steel beam, weighing approximately 2,000 lb, paired with a custom-fabricated flange engineered to capture and support the existing beam. The implementation challenge was significant: we had to remove the original steel post and seamlessly connect the existing beam to the new one, all while that existing beam was carrying the full weight of the cinder-block exterior wall on the second floor. With precise shoring, careful sequencing, and a highly coordinated installation, the transition was executed flawlessly. As the project photos show, every risk was anticipated, accounted for, and fully mitigated.

This project is a strong example of the type of technical, detail-driven structural work we excel at, complex load paths, steel-to-steel integrations, and high-risk conditions requiring exact execution. As we often say: the more challenging the project, the better suited we are to handle it.
