What Overzicht does

Overzicht is a Belgian BIM (Building Information Modeling) and VDC (Virtual Design & Construction) consulting firm headquartered in Antwerp, founded in 2017 by CEO Pieter De Bleser. The firm provides BIM consulting, coordination, modeling, management, and engineering studies to construction companies, architectural firms, industrial operators, and government bodies in Belgium, with named engagements on flagship infrastructure programs including the Port of Antwerp-Bruges Droogdok 5 renovation, the €3.5 billion Oosterweelverbinding (Lantis), and the €22 million Schrijverswijk social housing transformation.

Its core technical offering is structured as a three-tier service model: Level 1 covers classical BIM services (modeling, coordination, management, ISO 19650 implementation); Level 2 extends to VDC capabilities (4D planning via Bentley Synchro, 5D cost estimation via RIB CostX, 7D facility management via Autodesk Tandem, Digital Twin); and Level 3 delivers data integration (Construction Data Platform, Power BI dashboards, ETL automation, enterprise-wide integration). The firm's proprietary architecture links BIM geometry to a central construction datastore via IFC GUID, enabling per-element tracking of cost, CO2, planning, and supplier data. Its technology stack includes Revit, Dynamo, Navisworks, Dalux, Autodesk Construction Cloud, Enscape, Bentley Synchro, RIB CostX, Autodesk Tandem, Civil 3D, InfraWorks, Power BI, Python, and Simplebim — the last of which Overzicht resells in Belgium under a partnership with Datacubist.

Overzicht operates a quote-based, sales-led professional services model with three delivery forms: consultancy (strategic advice), capacity delivery (team augmentation), and outsourcing (task takeover). The ~10-person team engages directly with enterprise and government clients via a free consultation led by the CEO. Revenue streams consist of fee-based BIM consulting, coordination, modeling, management, and engineering studies, supplemented by Simplebim reseller licensing income. Marketing is content- and community-driven, centered on the BIMzicht blog, LinkedIn, and Buildwise / buildingSMART Belgium events, with no disclosed external funding and founder-controlled ownership.
