What D+A does
D+A nv is a privately held Belgian construction engineering consultancy headquartered in Halle (with a second office in Mechelen) that has operated continuously since 1971 under the legal entity D+A nv (enterprise number BTW BE 0418 913 997). The firm sells two integrated service lines: Studiebureau (a multidisciplinary design bureau covering spatial planning, landscape and outdoor-space design, technical infrastructure design, BIM modeling, stability studies, safety coordination, mobility engineering, and master planning) and Co-bouwheerschap (co-project management, where D+A acts as the client's single point of contact from concept through delivery for entrepreneurs, real estate developers, facility managers, and architects). Core technology consists of standard industry tools — AutoCAD Civil 3D for road and sewer design, Revit for BIM, Sirio and Infoworks for hydraulic modeling, and Standaardbestek 250 for tender specifications — with no proprietary technology disclosed.
The firm generates revenue on a project-by-project professional services fee basis across two parallel go-to-market motions: direct engagement with Flemish municipalities, provinces, and agencies (e.g., Province of Antwerp, Agentschap Wegen & Verkeer, NMBS) for infrastructure and spatial planning studies, and direct engagement with enterprise clients and developers (Delhaize, Multipharma, Lindemans, D'Ieteren Immo / Porsche) for large-scale industrial, logistics, and commercial construction projects, supplemented by referral relationships with architectural firms such as A2D, MaMu Architects, and Cosimco. Geographic focus is domestic Belgium (Flanders, with selective Wallonia and Brussels work); no international expansion is documented.

D+A competitors and assessment
Company assessmentBroad incumbents
- Tractebel (ENGIE): Tractebel is the Belgian engineering arm of ENGIE, providing large-scale consulting in infrastructure, energy, and urban development. It competes with D+A on complex Belgian infrastructure tenders but operates as part of a much larger utility-owned group.
- Arcadis Belgium: Arcadis is a global design, engineering, and management consulting firm with a Belgian operation spanning mobility, water, and buildings. It overlaps D+A on infrastructure design and project management but with vastly broader capabilities and resources.
