GLT

What GLT does

GLT+ is a Quebec-based, privately-held construction consulting firm founded in 1990 (originally as Gestion Lehoux et Tremblay) and headquartered in Saint-Hubert (Longueuil). The firm delivers six integrated service lines under a single roof: BIM (Building Information Modeling) management, project management, construction management (gérance de construction), construction economics and estimating, codes and standards advisory, and cost consulting. GLT+ also provides due diligence inspections and a more recently formalized technico-legal and claims practice led by an IMAQ-accredited mediator. Its BIM offering is the technical centerpiece — GLT+ deploys BIM Level 3 on major infrastructure, covering 3D coordination through 7D (operations), including 5D cost integration, 6D energy/ecological analysis, and constructibility workshops with general contractors.

The firm serves four primary customer segments: public sector owners (Société québécoise des infrastructures, Ville de Montréal, Ville de Brossard, Ville de Longueuil, STM, Hydro-Québec, Aéroports de Montréal, school boards and healthcare networks including CHU de Québec), private real estate developers (Devimco, COGIR, Groupe Montoni, Broccollini, Groupe Maurice), financial institutions providing construction financing (Banque Nationale, Desjardins, Fiera Capital, BMO, RBC, TD, CIBC, Scotia, Laurentian), and architecture/engineering firms seeking BIM and codes expertise (NEUF, Provencher_Roy, Menkes Shooner Dagenais LeTourneux, Atelier Pierre Thibault). As of late 2025 the firm operates with approximately 100 multidisciplinary specialists (up from ~75 in March 2025 and ~80 in 2020), has served more than 6,000 clients, contributed to over 15,000 projects with cumulative value exceeding $100 billion, and manages 150+ simultaneous cost consulting projects with portfolio value above $50 billion.

The business model is professional services fees billed on a per-project or retainer basis, with multi-year engagements typical for major infrastructure mandates (e.g., the $1.97 billion Nouveau complexe hospitalier at Enfant-Jésus, one of Canada's largest BIM projects). The firm is independently owned under a shared governance structure implemented in January 2025, with Co-Presidents Jasmin Martel and Ovidiu Maier jointly serving as Director General; twelve key employees were admitted as shareholders in November 2021. Sales are relationship-driven and led by senior executives through referrals, RFP responses, thought leadership, and professional training delivered via partners such as Contech Bâtiment and the Ordre des Architectes du Québec. Geographic focus is exclusively Quebec, with no disclosed international expansion.
