DWT Installatiegroep

What DWT Installatiegroep does

DWT Installatiegroep is a Dutch technical-installation services group headquartered in Goes, Netherlands, operating across six locations in Zuid-West Nederland. The group designs, installs, and maintains integrated building systems — electrical (E), mechanical/climate (W), and sanitation/plumbing (S) — for new-build, renovation, and operational maintenance projects across commercial, industrial, healthcare, hospitality, logistics, residential, government, and maritime/defence end markets. Revenue is generated primarily through project-based installation contracts with construction firms, developers, and institutional property owners, supplemented by recurring technical-management and maintenance agreements, technical consulting via the DWT Visie / DWT Techniek en Advies division, and prefab modular supply through subsidiary Preworxs BV.

The group operates under a holding-style structure with eight wholly-owned subsidiaries covering project execution, technical management, shared services, advisory, climate solutions (BIT Klimaatprofessionals BV), electrical/mechanical installations (Interdaad BV), prefab (Preworxs BV), and smart-building automation (Smartworxs BV). Underlying technology is centered on BIM-enabled 3D design collaboration, 3D totalstation surveying, KNX building automation, Teleworxs 24/7 remote monitoring tied to Building Management Systems, and in-house prefab manufacturing. The group holds a deep Dutch regulatory certification stack (ISO 9001, ISO 14001, VCA**, SCIOS scopes 1/7a/10, BRL 100/6000-21/6000-25/SIKB 11000, BRL6010 legionella, BMI-OAI, Safety Culture Ladder) and has delivered BREEAM-certified reference projects at Outstanding, Excellent, and 5-star levels. DWT Installatiegroep was formed on January 1, 2017, from the merger of Delta Techniek (founded 1978) and Wisse Techniek (founded 1953), and was named "Installatiebedrijf van het Jaar 2023."

Go-to-market is B2B/B2G enterprise field sales, executed through account management, public tender participation, and long-standing strategic construction partnerships (e.g., Bouwbedrijf Boogert, ~15-year relationship). Pricing is quote-based and project-specific; a 15-year maintenance contract on Dutch Ministry of Defence floating training platforms (Holland Shipyards Group) illustrates the recurring-revenue potential of the model. The group employs 185 direct staff and over 200 including subsidiaries, and reported €48 million in revenue for DWT installatiegroep BV in its most recent fiscal year.
