What IDDS does

IDDS Groep B.V. is a Dutch engineering and consultancy firm headquartered in Noordwijk, Netherlands, founded in 1988. The company provides multi-disciplinary services for spatial and area development projects, covering the full trajectory from research and advisory through to realization. IDDS operates across 9 knowledge areas: soil research and remediation, archaeology, conventional explosives detection (OCE/OOE), ecology, water management, cultural technology, planning, construction and demolition management, and civil engineering. Its core differentiation is the integration of subsurface expertise (archaeology, soil, water, ecology) with above-surface civil engineering and planning capabilities under one firm.

The company serves two primary customer segments: Dutch municipal and provincial government bodies requiring multi-disciplinary consultancy for spatial planning and regulatory compliance, and private developers and construction companies needing integrated site assessment, demolition management, and civil engineering support. IDDS holds relevant certifications including archaeology certification, CO2 Performance Ladder, and SMI circular material inventories. Technology tools include a 3D BIM model for underground visualization and specialized surveying plugins.

IDDS generates revenue through project-based professional services engagements delivered by its own teams. The company is privately held by director-owner Sibrand van Roijen (since November 2022) and has no disclosed external funding or institutional investors. It has pursued a partnership-led growth strategy, forming alliances with Civilink Ingenieursbureau (December 2022) and Van Riezen & Partners (December 2024), and exhibits at industry events such as PROVADA. The firm employs between 70 and nearly 100 professionals across its Noordwijk headquarters and serves clients across the Netherlands, with notable project activity in South Holland, Leiden, Haarlem, and Valkenburg.
