Hoogendoorn

What Hoogendoorn does

Hoogendoorn (legal name: Sanitair Installatie Hoogendoorn B.V.) is a Dutch sanitary installation specialist founded in 1930 in Woerden, Netherlands, and now in its fourth generation of family ownership under general director Pieter Hoogendoorn. The company focuses exclusively on utility construction, providing end-to-end sanitary installation services — including water supply, drainage technology, fire protection, and legionella prevention — for large-scale non-residential projects across the Randstad region (Amsterdam, Rotterdam, Utrecht, The Hague, and surrounding areas).

The company's core offering spans four integrated capability stages: advisory, engineering, execution, and management. Engineering is delivered through advanced BIM (Building Information Modeling) using Revit up to LOD500, enabling clash detection and facility management handover. Execution leverages an in-house prefabrication and modular construction workshop, complemented by specialized techniques such as infrared welding (infraroodlassen) for clean pipe joints. The service portfolio includes water management, leak detection systems, water-saving motion-sensor valves, and BREEAM/LEED/WELL sustainability certification support. The company holds BRL6000-AB (sections 7 & 8), BRL6010, VCA*, ISO 9001, ISO 14001, and Safety Culture Ladder certifications, with BRL6000-AB granting preferred supplier status at Schiphol Airport.

Hoogendoorn generates revenue through project-based professional services contracts with enterprise clients, including developers, general contractors, and building owners. Notable projects include the Mall of the Netherlands (Unibail-Rodamco, 57+ km of piping), Rosewood Hotel Amsterdam, ING's new 51,000 m² headquarters (Linden Amsterdam), ABN AMRO's Circl Pavilion, Marriott's Tribute Hotel, DuPont's Leiden research lab, Wonderwoods in Utrecht, and project MORE (705 sustainable student dwellings). The company employs approximately 70 staff and operates from a new modern office and workshop along the A12 in Woerden.
