What MH Poly does

MH Poly Consultants & Engineers B.V. is a privately held Dutch engineering and consulting firm headquartered in Bergen op Zoom, Netherlands. Founded in 2008 through the merger of MH Nederland B.V. (Zwijndrecht) and Ingenieursbureau Poly Construction B.V. (IPC, Bergen op Zoom), the firm operates across three interconnected service domains: Milieu & Ruimte (environmental and spatial engineering, including soil and waterbed surveys, remediation, and environmental guidance), Waterbouw & Infra (hydraulic engineering and civil infrastructure such as ports, locks, bridges, tunnels, and quays), and Industrie & Constructies (industrial construction design and calculations, including pressure vessels, piping, and skid engineering). It serves government infrastructure agencies (Rijkswaterstaat, provincial and municipal governments), construction firms and consortia (BESIX, Ballast Nedam, Combinatie Roggebot), and private-sector industrial companies. The firm holds a niche reputation in immersion tunnel (afzinktunnel) engineering — temporary works, ballast systems, mooring, and towing/immersion operations.

Technically, MH Poly delivers multidisciplinary engineering rather than a software product. Its notable technical components include 3D printing for producing physical scale models to validate designs pre-construction, RFEM calculation software integrated with the VIKTOR platform (via supplier MSc Engineering) for automated engineering workflows, and a GIS platform supporting spatial data analysis and environmental mapping. The firm maintains BRL-SIKB certifications (1000, 2000, 6000, 6005, 6007) and NEN-4400 certification required for regulated environmental and soil investigation work.

The business model is professional-services based: revenue is generated through project-based engineering and consulting engagements won via public tendering, direct commissions, and industry networks, with quotes issued per project scope. Go-to-market is direct enterprise/field sales supplemented by trade-event presence (Waterbouwdag, InfraTech, KIVI excursions), trade-journal publications, and organic social channels. No pricing is publicly disclosed and no revenue figures are available. The firm employs 11–50 people and operates internationally, with projects spanning the Netherlands, Belgium, Germany, Sweden, Iraq, Turkey, and Canada.

Broad incumbents

• Royal HaskoningDHV: Major Dutch-headquartered engineering consultancy with deep water, maritime, and infrastructure expertise including ports, tunnels, and flood defense. Overlaps significantly with MH Poly's Waterbouw & Infra service line but operates globally across many more verticals at much larger scale.
• Fugro: Dutch-headquartered geo-data and site characterization specialist serving marine, infrastructure, and environmental markets. Comparable to MH Poly in the geotechnical, soil investigation, and waterbed survey capabilities, though Fugro operates at global scale with significant offshore and survey vessel operations.
• Arcadis: Global design and engineering consultancy with significant water, infrastructure, and environmental consulting practices. Competes with MH Poly in Dutch and European water/infrastructure projects but at much larger scale and across a far broader service portfolio.
• Stantec: Global engineering, architecture, and environmental consulting firm with significant water resources and infrastructure practices. Overlaps with MH Poly's environmental and water engineering offerings, particularly relevant for projects where the firms bid against each other on European tenders.
• WSP: Global engineering professional services firm with strong water, environment, and infrastructure practices. Overlaps with MH Poly's Waterbouw & Infra and Milieu & Ruimte offerings, though at vastly larger scale and global footprint.

Direct peers

• Antea Group: Engineering and environmental consulting firm operating across infrastructure, water, and environment. Comparable to MH Poly in environmental/site assessment and water infrastructure work, particularly in the Netherlands and broader European market.
• Sweco: Northern European engineering consultancy with strong water, infrastructure, and environmental practices. Comparable to MH Poly in service mix (hydraulic engineering, environmental assessments, bridge and tunnel work), though larger and headquartered in Sweden rather than the Netherlands.
• Witteveen+Bos: Dutch engineering consultancy specializing in water, infrastructure, and environmental projects. Highly comparable to MH Poly in domain mix (deltas, locks, bridges, environmental assessments) but at substantially larger scale, making it the closest direct mid-sized peer in the Dutch water engineering market.
• MBM Engineers: Dutch strategic cooperation of three engineering firms bundling project capabilities, explicitly partnered with MH Poly since 2024. Highly comparable in size and engineering consulting model, making it the most direct small-scale peer and most likely co-bidder on Dutch infrastructure work.
