Throughout the decades we have developed a great capacity to carry out technically demanding projects, and to lead and coordinate multidisciplinary teams. Our collaboration with Hydro-Québec dates back to the beginning of the 1980s, and we possess considerable mastery in the context of intervention and in the specific concerns connected to industrial projects. This expertise is based on about a hundred projects: substations, control buildings, 25-31 kV distribution centres, interpretation centres, compact automation buildings (CAB), administrative centres, air terminals, developments, renovations and upgrading.
Industrial architecture presents a set of specific and all-encompassing technological challenges, both in terms of design and realization. These include the integration of various electric systems and the implementation of equipment, commands and massive underground electric conduits, as well as the interaction of these systems with the building itself. This interaction requires all the more care when it comes to building new substations, especially with 25 kV manoeuvring stations and isolated SF6-run, 315 kV electrical rooms, enabling the greater management of the electric distribution on a dense and irregular site with reduced ground space. The technology is primarily used within new substations in urban settings, as it doesn’t take up much room and is relatively silent compared to compressed-air circuit breakers. Urban localization further requires additional effort and particular consideration when it comes to architectural treatment, clearances, setbacks, and the breakdown of masses. The DeLorimier (2017), Bélanger (2015) and Henri-Bourassa (2014) substations are excellent examples of this effort, in addition to the criteria for sustainability, function, and longevity of the materials used.
Alongside Hydro-Québec, we have developed and realized various compact automation buildings, popularly known as CAB. CAB requires a high level of prefabrication and is part of a rigorous process of rationalization with Hydro-Québec. This acquired expertise, developed with Hydro-Québec, demonstrates the involvement and reach that our services present to clients.
