GROUPE CONSEIL CHG INC.

What GROUPE CONSEIL CHG INC. does

GROUPE CONSEIL CHG INC. (legally Del Degan, Massé et Associés et Groupe Conseil CHG Inc.) is a private Quebec-based multidisciplinary consulting firm operating under the unified DDM × CHG brand since 2025-2026. The firm combines two practices: Groupe DDM, founded in 1987 by Bruno Del Degan and Bernard Massé with deep forestry and geomatic roots, and Groupe Conseil CHG, established in 2016 under Charles Gauthier as the civil engineering division. A combined team of 80+ professionals delivers 12 service lines — infrastructure, structural engineering, hydraulics/hydrology, surveying and drone LiDAR, transportation, project management, environmental services, economic studies, forestry, geomatics, strategic planning, and urban planning — to public-sector and private clients primarily across Quebec from offices in Quebec City, Montreal, and Chicoutimi.

The firm builds its service delivery on internally-controlled technical assets, most notably the CHG Drone LiDAR survey platform (DJI M600 Pro equipped with YellowScan Mapper, delivering 3cm absolute precision and 200+ points/m² density for topographic and bathymetric work) and ArcGIS Online-based spatial data management for forestry and environmental inventory projects. It holds ISO 9001 certification (obtained c. 2000), is registered with Quebec's Autorité des marchés financiers, and maintains mandatory professional order memberships (OIQ, OIFQ, OUQ, ABQ, SIAQ) in addition to industry association ties (AQEI, CPEQ). The firm has completed 1,800+ projects since 1987 for a client base dominated by Quebec municipalities, government departments (MRNF, Ministère des Transports), state enterprises (Hydro-Québec), and regional county municipalities (MRCs).

The business model is fee-for-service professional consulting, with project-based pricing tied to scope, complexity, team composition, and duration. Engagements are acquired through direct client relationships and competitive RFPs in the public-sector procurement channel, then delivered by multidisciplinary teams often spanning several practice areas within a single mandate. Customer concentration is heavily skewed toward Quebec government and municipal clients, with a smaller and less visible private-sector book. The firm is privately held with no external investment or parent company identified, and revenue is not publicly disclosed.
