BESIX Unitec Tech Stack

Infrastructure contractor specializing in utilities, telecom, and transport networks

Construction Schelle, Schelle 501–1,000 employees Founded 1973 Public Company

BESIX Unitec builds and manages large-scale infrastructure projects across utilities, telecom, roads, railways, and waterways. The tech stack reveals a hybrid operations model: heavy CAD and BIM for design (AutoCAD, Enterprise Architect), industrial control systems for site management (Siemens TIA Portal, WinCC OA, VTScada), and emerging data tooling (BigQuery, Python, Power BI, Microsoft Fabric) to address reported data quality gaps and compliance tracking. Hiring leans construction (50% of openings) with mid-level dominance, while pain points cluster around safety/environmental compliance and process optimization rather than digital transformation.
