What De AdviesGroep Nederland does
DAGnl (De AdviesGroep Nederland) is a Dutch multidisciplinary engineering and environmental consultancy headquartered in Olst, Netherlands, operating nine regional offices and employing more than 200 people. Founded in 2011, the company runs twelve in-house expertises under one roof: civil engineering, soil research and remediation, archaeology, spatial planning, ecology, urban planning, land surveying, explosives research and advice, energy transition and sustainability, asbestos inventory, sports facility planning, water management, and urban green. Services are delivered through wholly-owned subsidiaries including Greenhouse Advies, Buro Noord, Buro Hoogstraat, Civil Management, Civil Works, Pro Ruimte, Xplosure, GRAS Advies, Incite Projects, and Buro Stedenbouw.
The firm's technical stack centers on CAD/GIS tools, 3D modeling (AutoCAD, Civil 3D, Revit), drone and laser scanning, and proprietary assessment methodologies. DAGnl has developed four proprietary products: Damwand CoCon, a recycled plastic modular construction that slides over existing timber sheet pile walls to extend lifespan by 50 years at 15% lower cost than full replacement; SMI (Sustainable Material Inventory), an integral inventory method for renovation and demolition projects, in which DAGnl was the first company nationally certified; the DAGnl Fauna-Ark, a modular wildlife shelter for protected species recognised under the Dutch Wet Natuurbescherming; and Circulair Soils, a digital soil-stream platform launched in December 2025 to support early insight into soil quality and circular reuse across projects.
DAGnl operates as a professional services firm, generating revenue through engineering, advisory, design, research, and supervision delivered under framework contracts, direct commissions, and public tenders on a quote-based pricing model with monthly billing. Primary customer segments are Dutch municipalities, provinces, and water boards (government) and project developers; named clients include VGP, Gemeente Deventer, Gemeente Almelo, Waterschap Zuiderzeeland, Jumbo Supermarkten, Het Nationale Park De Hoge Veluwe, Gemeente Zevenaar, Gemeente Ermelo, BOEi, and Jan Keldersbeheer BV. The firm holds ISO 9001, ISO 14001, VCA*, CO2-prestatieladder level 3, BRL 2000/4000/6000, CS-VROO, and SMI certifications. No public-facing API, AI/ML products, or SaaS platform are offered, and revenue is not publicly disclosed.

Products and services
- Damwand CoCon(struction) A modular recycled-plastic construction product that slides over an existing cut timber sheet pile to extend its lifespan by 50 years (from ~25 to 50 years). Reuses two-thirds of the existing wooden plank, is suitable for limited working-height situations, uses cradle-to-cradle materials, and is at least 15% cheaper than full replacement at distances up to 50 metres. Targeted at water boards and infrastructure owners facing deteriorating timber sheet pile walls.
- SMI: Sustainable Material Inventory An integral inventory method for renovation and demolition projects that maps materials and hazardous substances (including chromium 6, PCBs, ionizing smoke detectors, pigeon droppings), determines circular reuse possibilities based on the R-ladder, and provides stoffenverantwoording (material accountability). Used by building owners, developers, and renovation contractors seeking circular demolition certification.
- DAGnl Fauna-ark A modular wildlife shelter designed as temporary or permanent shelter for building-dwelling animal species including bats, swifts, house sparrows, and black redstarts. Each unit is monitored for microclimate and occupancy. Design is based on BIJ12 guidelines and approved by competent authorities under the Wet Natuurbescherming. Used as a mitigating measure during construction projects to comply with nature-protection permits.
- Circulair Soils A digital platform that aggregates all soil streams in one environment, providing early insight into soil quality and supporting smart reuse of soil to make projects more efficient and sustainable. Targeted at developers, contractors, and soil management stakeholders seeking circular soil management.
