What construction blg does
Construction BLG is a Quebec-based general contractor founded in 1999 that delivers construction and renovation services across three segments: Residential, Commercial, and Institutional. The firm is registered with Quebec's Régie du bâtiment du Québec (RBQ license 8248-1003-00) and operates as a small organization of 1-10 employees under director Stéphane Boisvert, drawing on a broader curated network of 30+ trade collaborators to execute work.
The company's service offering is structured around three delivery models designed to match different client procurement preferences: turnkey (clé en main), where the firm assumes full project responsibility; project management (gérance), where it acts on behalf of the client; and time-and-materials, where work is billed against actual labor and inputs. This three-model structure allows engagement across owner-occupier residential renovations, private commercial fit-outs, and publicly tendered institutional contracts.
The customer base spans individual residential clients and named institutional and enterprise buyers, including CHUM, SAQ, Ville de Montréal, Bombardier, Canada Post, and major Canadian banks. Geographic coverage extends across multiple Quebec regional markets. The firm is headquartered at a single Quebec office, and its public-facing material carries a 2017 copyright. Revenue is generated through project-based contracts — there is no subscription, recurring, or SaaS component to the model.
