Working at Croonwolter&dros

What Working at Croonwolter&dros does

Croonwolter&dros is one of the largest Dutch technical installation companies, employing over 3,000 professionals organized into four operating divisions — Utiliteit (utility buildings), Energie (energy), Industrie (industry), and Infra (infrastructure) — and operating from 13+ offices across the Netherlands. The company delivers the full project lifecycle for complex mechanical, electrical, automation, and IT installations: BIM/Revit-based design and engineering, work preparation, assembly, project management, commissioning, and ongoing service and maintenance contracts. Notable technical capabilities include in-house building automation (M&R) using Priva, Siemens, and Saia-Burgess platforms; PLC/SCADA programming across Siemens TIA-portal, PCS7, WinCC OA, Schneider Control Expert, and ABB 800xA; high-voltage installations up to 380kV; high-end security and cybersecurity (GBBS); and SAP S/4HANA-supported maintenance operations. Customers are predominantly large enterprises, grid operators, and government entities, including Alliander, TenneT, Rijkswaterstaat, Rijksvastgoed (Tweede Kamer Binnenhof), Schiphol, Radboud Universiteit, and unnamed hospitals, universities, and defence sites.

The company generates revenue primarily through B2B technical services contracts delivered via direct enterprise sales and public tenders. Revenue streams include large one-time project work (€10M–€100M+ national projects, €100K–€4M regional projects) and recurring maintenance and service contracts (e.g., 50+ Alliander locations). The company is privately held and operates as a subsidiary of TBI Holdings B.V., a Dutch construction and engineering conglomerate, alongside sister companies J.P. van Eesteren and Aannemingsbedrijf Nico de Bont. Distribution is exclusively direct, with no external recruitment agencies — the company runs an in-house recruitment team of 19+ recruiters and a dedicated employer brand portal (werkenbij.croonwolterendros.nl) to source technical talent from universities, BBL programs, dual study programs, and traineeships. Marketing is employer-brand-focused rather than customer-acquisition-focused, reflecting a public-tender and relationship-driven sales motion.
