What Groupe DDM does
Groupe DDM, legally Del Degan, Massé et Associés, is a Quebec-based multidisciplinary engineering and consulting firm founded in 1986. The firm delivers professional services across 12 expert domains: infrastructure, structural engineering, hydraulics and hydrology, surveying (including drone and bathymetry), transportation, project management, environment, economic studies, forestry, geomatics and IT, strategic planning, and urban planning. Its client base spans both the public sector (municipalities, government agencies) and private-sector developers and industrial clients operating in Quebec.
The firm has formalised a strategic alliance with Groupe Conseil CHG, operating under a unified "DDM × CHG" brand that combines the two complementary practices into a single integrated offering. The combined entity holds professional certifications and order affiliations across Quebec regulators (OIQ, OIFQ, OUQ, ABQ, BNQ, and others), positioning it to compete for regulated infrastructure, municipal engineering, and environmental mandates. Service delivery relies on conventional engineering consulting workflows — survey and field data capture, analysis, design, and project management — augmented by geomatics and IT capabilities, though no proprietary technology platform or product is identified.
The business model is fee-for-service professional consulting, with revenue tied to project-based engagements (infrastructure design, environmental assessments, feasibility studies, and municipal planning mandates). Pricing is project- or hourly-based under typical Quebec public-tender and private-contract terms. The firm employs 11-50 staff, and revenue is not publicly disclosed.
