Core offering

Tijhuis Ingenieurs is an independent Dutch engineering consultancy providing full-lifecycle regional water management services: waterbed surveys and sediment sampling (veldwerk), advisory on dredging, water quality and nature-friendly bank design, contract and tendering support, and execution supervision. The firm supports these services with the proprietary WIT online management platform and specialized equipment such as the HydroScout multibeam survey vessel, drone-based ecological surveys, and self-developed field tools. Clients are Dutch water boards, municipalities, provinces, and nature conservation organizations.

Product overview

Tijhuis Ingenieurs offers a modular product ecosystem centered on WIT (Waterbodem Informatiesysteem), an online water bottom management system comprising five modules: Meting, Meerjarenplanning, Data, Uitvoering, and Waterpaspoort. This platform is complemented by WIT Metingen, a field work application for data collection. The company also provides specialized services including drone-based ecological quickscans and equipment such as the HydroScout multibeam USV, titanium suction dredges, and spray lances for specialized measurement tasks. All products and services support the company's core business of sustainable regional water management in the Netherlands.

Products and services

• WIT (Waterbodem Informatiesysteem Tijhuis) Online management system for organizations with water or waterbed maintenance obligations, comprising five modules (Measurement, Multi-Year Planning, Data, Execution, Water Passport) sharing one central database. Sold and serviced separately to clients across the Netherlands.
• HydroScout with multibeam survey service Survey service using an unmanned surface vessel equipped with Cerulean Surveyor 240-16 MBES and Trimble BX992 with INS, enabling flat-coverage measurement of shallow waterway beds (0.75–5.0 m depth). Delivered as a service for waterboards, municipalities, and other clients.
• Ecologische quickscan vanuit de lucht (Drone-based ecological survey) Service using a professional drone with high-quality camera and thermal imaging to perform ecological surveys from the air, including wildlife population studies (e.g., hare populations) and assessment of inaccessible areas early in project preparation.
• Titanium zuigerboor (Titanium suction corer) Self-developed titanium suction corer used for waterbed sampling, lighter and more ergonomic than traditional steel versions, with laser-marked measurements on the frame and handle for practical field use.
• Spuitlans (Spray lance) sheet pile measurement tool Innovative non-destructive tool for determining the position of the underside of sheet piling by displacing soil with water pressure, capable of measuring up to five meters below the waterline.
• Veldwerk (Fieldwork services) Field-based data collection services covering bathymetric soundings, sediment sampling, waterbed research, and flora/fauna inventories, performed by field workers operating throughout the Netherlands.
• Advies (Advisory services) Engineering advisory services covering nature-friendly bank design, sediment processing advice, permit applications, and preparation of bestekken (specifications) across the full project trajectory from research to execution.
• Contract en aanbesteding (Contract and tendering support) Support with contract preparation and public procurement (aanbesteding) processes for dredging and civil engineering projects undertaken by public-sector clients.
• Uitvoering (Execution supervision and direction) Directievoering and toezicht (supervision and direction) services that bridge clients and contractors during execution of dredging, sediment remediation, and civil works, ensuring quality is maintained.

Partnerships

Five partnerships are on record, tiered core and supporting.

• GeometiuscoreTechnology or Integration · 1 September 2025Geometius delivered the first HydroScout with multibeam in the Netherlands to Tijhuis Ingenieurs. The HydroScout is equipped with Cerulean Surveyor 240-16 MBES and Trimble BX992 with INS, enabling flat-coverage measurement of shallow waterways. This is a core technology partnership for the company's innovation strategy in waterbed surveying.
• SKAO (Stichting Klimaatvriendelijk Aanbesteden en Ondernemen)coreOthers · 1 January 2015SKAO is the governing body of the CO2 Performance Ladder. Tijhuis Ingenieurs is certified at level 5 and participates in the scheme, which also provides procurement advantages for their projects.
• Marine Sampling Holland (MSH)supportingStrategic or Co-development PartnerMarine Sampling Holland collaborated with Tijhuis Ingenieurs on waterbed research in the Eemsgeul (Wadden Sea). MSH performed vibrocore borehole sampling from a Rijkswaterstaat vessel, while Tijhuis Ingenieurs' field worker described the bore and compiled samples for waterbed research. This partnership enables the company to conduct offshore fieldwork.
• MovaressupportingStrategic or Co-development PartnerTijhuis Ingenieurs acted as subcontractor to Movares for the Molenpolder legakker restoration project, commissioned by Staatsbosbeheer. The project involved detailed design, permit testing, specifications, and construction supervision for legakker reconstruction.
• SIKBcoreStrategic or Co-development PartnerTijhuis Ingenieurs cooperated with SIKB and other sector experts to develop the Veldwerk Waterbodemonderzoek (Fieldwork Waterbed Research) training program. Several of the company's field workers also teach practical courses. SIKB manages certification schemes including BRL 2003 and BRL 6003 that Tijhuis Ingenieurs holds.

Broad incumbents

• Arcadis Nederland: Global design and consultancy firm with a substantial Dutch water and environment practice. Competes for the same waterschappen and municipal tenders, with overlap on waterbed remediation and BRL-certified advisory work.
• Royal HaskoningDHV: Largest Dutch-headquartered engineering consultancy, with a sizable water and delta technology practice serving global and Dutch clients. Competes with Tijhuis on waterbed and dredging advisory at the larger end of tenders, including for major waterschappen and Rijkswaterstaat programs.
• Sweco Nederland: Large pan-European engineering consultancy with substantial Dutch water management practice serving public-sector clients. Operates at greater scale and broader scope than Tijhuis, but overlaps directly on waterbed, dredging, and water quality advisory for the same waterschappen and municipal clients.
• Fugro: Dutch-headquartered global geo-data specialist with hydrographic survey capabilities relevant to waterbed mapping. Overlaps with Tijhuis in shallow-water multibeam survey work and is a comparable provider of high-resolution waterbed data to Dutch water boards, though at much greater scale and broader scope.

Direct peers

• Witteveen+Bos: Dutch-headquartered engineering consultancy with a large dedicated water, delta, and infrastructure practice serving waterschappen, Rijkswaterstaat, and gemeenten across the Netherlands. Most direct competitor in the same public-sector water management niche, with overlapping services in dredging advisory, waterbed research, and nature-friendly bank design.
• Tauw: Dutch environmental consultancy with strong water and soil practice, including dredging supervision and waterbed remediation advisory. Comparable in target customers (waterschappen, gemeenten), BRL certifications, and mix of fieldwork plus advisory services.
• Antea Group: Dutch environmental and infrastructure consultancy providing water, soil, and spatial planning services to Dutch public-sector clients. Highly comparable on BRL-certified milieukundig waterbodemonderzoek and waterbed remediation advisory work for waterschappen and municipalities.
• Lievense CSO: Dutch engineering consultancy with dedicated water and infrastructure practice serving waterschappen and municipalities. Comparable scale and service mix, including dredging supervision, waterbed research, and nature-friendly bank design.

Emerging players

• Wareco: Dutch specialist consultancy focused on waterbed, dredging, and environmental engineering for waterschappen and municipalities. Closest mid-sized peer in terms of service portfolio and target customers, though smaller than the major incumbents.

Others

• STOWA (Stichting Toegepast Onderzoek Waterbeheer): Dutch foundation of waterschappen that commissions applied research on water management. While not a competitor, STOWA is an ecosystem participant that funds and disseminates research that informs the dredging and waterbed advisory work Tijhuis performs for its waterschap clients.
