What Witteveen+Bos does

Witteveen+Bos is a Dutch engineering and consultancy firm, founded in 1946 and headquartered in Deventer, that delivers multidisciplinary professional services across 11 defined expertise areas: Spatial Planning, Landscape/City/Building, Energy, Water, Industry, Nature/Environment, Deltas, Maritime, Infrastructure, Mobility, and Digital Solutions. The firm is structured as a public limited company (N.V.) wholly owned by its employees, with all shares held by staff and an explicit partner-track progression model that creates long-term alignment between consultants and firm performance. Revenue is generated through project-based professional services engagements acquired via public tenders, European procurement procedures, and direct client relationships; pricing is not publicly disclosed and is typical of the engineering consultancy sector (input data shows no public pricing).

The company operates 21 offices across 9 countries (Netherlands, Belgium, United Kingdom, Latvia, Singapore, Indonesia, Kazakhstan, United Arab Emirates, Panama) and executes approximately 5,000 unique projects per year with a workforce of 1,700+ engineers and consultants. Its primary client base is public-sector: Dutch national ministries, Rijkswaterstaat, 10+ regional water authorities, the Ministry of Infrastructure and Water Management, the Flemish Agency for Roads and Traffic, Lantis (Antwerp Ring Road), Brussels Airport Company, and municipal governments. Private-sector exposure includes real estate developers (Suryam Developers), with work spanning flagship infrastructure programs (Oosterweelverbinding, Verapaz Bridge, Brussels Airport redesign) and specialized innovations such as the award-winning eDNA Meets Toxicity water-quality methodology (De Vernufteling 2025 jury and public prizes) and the Power2Tow offshore charging infrastructure blueprint for the North Sea.

The firm monetizes primarily through billable consultancy hours and project fees on large multi-year public infrastructure programs, supplemented by consortium arrangements for mega-projects (THV ROTS / THV ATLAS with Sweco on Oosterweel; Belgian-Dutch consortium on Brussels Airport). Recent strategic activity includes the 2025 acquisition of Maidl Tunnelconsultants to add tunnel expertise, a 2025 strategy and governance model refinement, opening a new The Hague office, commercialization of the eDNA Meets Toxicity service, and the June 2026 launch of the multi-year Biodiversity in Focus (BiB) research program with Deltares and a broad Dutch public-private consortium. Revenue figures are not publicly disclosed in the available data.

Products and services

• eDNA Meets Toxicity Water quality monitoring service using environmental DNA (eDNA) food web analysis to assess toxic pressure on aquatic ecosystems. From a single one-litre water sample, more than 5,000 unique DNA sequences are extracted via PCR and next-generation sequencing and compared against reference databases, allowing clients to map underwater biodiversity and link ecological patterns to chemical contamination.
• Power2Tow Offshore Charging Infrastructure Blueprint Engineering blueprint and design service for offshore electric charging infrastructure in the North Sea, enabling emission-free deployment of Emergency Response and Towing Vessels (ERTVs) near wind farms. Includes evaluation of e-tower (fixed monopile) and e-buoy (floating anchored) charging concepts engineered to withstand waves up to 10 metres and reduce segment production time.
• Harmonisation Tool Digital solution for harmonization within Witteveen+Bos's digital solutions portfolio, supporting engineering and consultancy workflows.
• DC eHubs Digital solution supporting the planning and engineering of direct-current (DC) electric hubs, part of the Witteveen+Bos digital solutions portfolio.
• Brussels Airport Infrastructure Design Comprehensive airport infrastructure design service delivered to Brussels Airport Company through a Belgian-Dutch consortium (Witteveen+Bos, Benthem Crouwel Architects, OKRA, Stramien), covering a new intermodal hub, expanded departures/arrivals hall, hotel, and a green boulevard with urban park.
• Oosterweelverbinding (Oosterweel Link) Major European infrastructure engineering service for closing the Antwerp Ring Road for client Lantis (Leefbaar Antwerpen). Witteveen+Bos and Sweco provide the complete study for ring closure, including stacked cut-and-cover tunnel design, landscape integration, and ecological considerations.
• Verapaz Bridge Ghent Bridge engineering and construction service delivering two decks spanning over 100 metres each across Handelsdok in Ghent, Belgium, in collaboration with MAAT Designers and Marie-José Van Hee Architects for improved traffic flow and neighborhood livability.
