Nepocon

What Nepocon does

Nepocon is a Dutch engineering consultancy founded in 2011 and headquartered in Hengelo, Netherlands, providing engineering, research, and advisory services for civil, hydraulic, and building structures as well as water management. The firm operates across six regional offices (Hengelo, Amersfoort, Schiedam, Leiden, Heemskerk, and Arnhem) with approximately 70 professionals, organized into five work fields: Structures, Steel and Mechanical Engineering, Water Management, Geotechnical Engineering, and Construction and Industry. Its service portfolio spans the full project lifecycle from concept (VO) and definitive design (DO) through execution design (UO), contract preparation, construction management (directievoering en toezicht), and asset management, with specialized advisory in structural safety, dewatering, foundation research, and urban water.

The company is organized under the Engius holding company and has executed a roll-up strategy, acquiring Akerveld Engineering (steel and mechanical, 2022), Schaal Ingenieurs (civil and foundation restoration, 2022), Technisch Buro de Heer (steel and concrete, 2023), and partnering with Solid Services (maintenance, 2023); Akerveld was rebranded to Nepocon Staal en Werktuigbouw B.V. in April 2025. Its technology stack centers on digital engineering using BIM, 3D modeling in Tekla Structures and Revit, parametric design, and Virtual Reality visualization to reduce failure costs via early clash detection. Nepocon is ISO 9001:2015 certified, holds the CO2 Performance Ladder Level 3, and is a recognized training company (Erkend Leerbedrijf); it is targeting CO2-neutral operations by 2030.

Nepocon earns revenue through project-based professional services fees across two primary customer segments: Dutch contractors (aannemers) and government agencies (waterschappen, gemeenten, provincies, Rijkswaterstaat), with additional work for steel/industrial equipment suppliers. Projects are acquired through tender processes (UAV-GC, RAW, bouwteam), referrals, and long-term client relationships; named customers include ProRail, Gemeente Rotterdam, Royal FloraHolland, Ziggo Dome, and Jan de Jonge. Pricing is not publicly disclosed. Following an April 2024 leadership transition, the firm is led by General Director Karst Jan Karsten and Technical Director Peter-Paul Heideman, while founder Frank Tijhuis focuses on parent company Engius.

Core offering

Nepocon is a Dutch engineering and advisory bureau that delivers project-based professional engineering services for civil, hydraulic, and building constructions. Its work spans five work fields — Constructies (Structures), Staal- en Werktuigbouw (Steel and Mechanical Engineering), Water (Water Management), Geotechniek (Geotechnical Engineering), and Bouw en Industrie (Construction and Industry) — from concept (VO) and definitive design (DO) through execution design (UO), contract preparation, supervision, and asset management. The firm applies digital engineering methods (BIM, parametric design, VR) and serves contractors, government agencies, and industrial clients across the Netherlands.

Product overview

Nepocon is a unified engineering and advisory firm offering integrated services across five core work fields: Constructies (Structures), Staal- en Werktuigbouw (Steel and Mechanical Engineering), Water (Water Management), Geotechniek (Geotechnical Engineering), and Bouw en Industrie (Construction and Industry). The company operates as a single integrated organization rather than a platform-plus-modules architecture. Their service portfolio includes Digital Engineering (using BIM, parametric design, and VR), V&R (Replacement and Renovation), Constructief Ontwerpen (Structural Design), Contractvoorbereiding en Projectmanagement (Contract Preparation and Project Management), Constructieve Veiligheid (Structural Safety), specialized water services (Bemalingsadvies, Stedelijk Water, Waterbouwkundige Constructies, Funderingsonderzoek), and Waterhuishoudkundig Plan (Water Management Plans). Services are delivered across multiple Netherlands locations, with the Steel and Mechanical Engineering division operating as Nepocon Staal en Werktuigbouw B.V. (formerly Akerveld Engineering, rebranded April 2025).
