This experience has been built on a variety of projects, including concrete installations in Saint-Barnabé-Sud , where climatic parameters, building typology, and usage patterns demand a rigorous approach from the design stage. Deployment on the South Shore relies on a structured organization, notably through the Boucherville service point, enabling efficient coordination of installation projects without restricting the company's overall scope of operations. This entire approach is presented here solely from the perspective of new systems , in line with current performance and compliance requirements.
