IGG Bouweconomie

What IGG Bouweconomie does

IGG Bouweconomie BV is an independent Dutch construction cost management and building economics consultancy headquartered in The Hague, founded in 1988 and operating with 51–100 employees under director/owner Arno Vonk MRICS. The firm advises project developers, architects, government bodies, and infrastructure clients across the full construction lifecycle on budget estimates, feasibility studies, cost control, tender management, second opinions, NEN 2580 area measurement, and BIM-integrated cost calculation. Marquee engagements include the Feyenoord City district and stadium, Paleis Het Loo museum renovation, Amsterdam ArenA expansions, Equinix datacenters, Flora Holland, and government housing for the House of Representatives, indicating a track record on complex Dutch public and private sector projects.

The company's core technology platform centers on proprietary cost databases and software, headlined by the BouwkostenKompas publication series (over 1,000 cost indicators across approximately 1,250 building types in housing, utility, GWW, and installations), the quarterly BouwkostenIndex tracking Dutch construction cost and procurement trends, the European Construction Costs platform covering up to 50 countries, and BIMCalc for direct cost calculation within Autodesk Revit models. Mobile apps (BouwkostenIndex, Bouwleges, BREEAM/Kompas) extend the data tools to iOS and Android, and the firm holds ISO 9001:2015 certification since 2017.

Revenue is generated through a hybrid model combining project-based professional services advisory with recurring subscriptions to publications, online calculation tools, and mobile applications. Distribution occurs through direct consulting engagement, the Bouwkosten.nl webshop operated by subsidiary Calcsoft BV, the constructioncosts.eu European platform, app stores, and annual presence at the PROVADA real estate fair. MeetAtelier, a wholly-owned subsidiary, provides NEN 2580 measurement services. The firm has no external funding, is founder/management-owned, and is expanding its European footprint via the Euro Alliance partnership while extending into circular construction and sustainability cost methodology.

Direct peers

• Linesight: Construction cost consultancy specializing in data centers, commercial real estate, and infrastructure projects. Particularly comparable to IGG given IGG's data center advisory work with Equinix; both serve mission-critical construction with cost management expertise.
• BBN Adviseurs: Dutch consultancy firm specializing in building economics, cost management, and facility cost advisory. Closest Dutch specialist peer to IGG in service offering, scope, and target client base of developers, government, and healthcare.
• Currie & Brown: International construction cost management and consultancy firm providing cost estimating, project monitoring, and advisory services. Direct competitor in the pure-play construction cost advisory niche, comparable to IGG's consulting services.
• Rider Levett Bucknall (RLB): Global independent construction cost consultancy (quantity surveying and cost management) with offices worldwide. Closest pure-play peer to IGG in service offering and independent positioning, though at significantly larger scale.

Broad incumbents

• Arcadis: Dutch-headquartered global design, engineering, and consultancy firm with cost management as part of its broader project services portfolio. Competes with IGG in the Netherlands but typically bundles cost services with design and engineering mandates.
• Turner & Townsend: Global construction cost consultancy and project management firm with significant cost advisory practices across infrastructure, real estate, and natural resources. Highly comparable to IGG as a direct cost management specialist, but at much larger scale and broader geographic reach.
• AECOM: Global infrastructure consulting firm offering cost management and quantity surveying within its broader project management and engineering services. Competes for large complex project mandates where IGG also operates.
• Royal HaskoningDHV: Dutch engineering consultancy offering project advisory and cost consultancy services alongside broader engineering and design capabilities. Direct competitor for Dutch construction cost mandates, though positioned as a full-service firm.

Regional players

• Sweco: Nordic-headquartered engineering and design consultancy with growing presence in the Netherlands and broader European cost advisory market. Comparable in service mix but stronger in Northern Europe than in IGG's Dutch core market.
• Witteveen+Bos: Dutch engineering and consultancy firm with construction cost and project advisory capabilities. Comparable as a Dutch-headquartered consultancy serving similar client segments, though broader in engineering scope.
