Process Engineer

Company Overview

Since first going into action in 1909, the BESIX Group has over the years grown into a multidisciplinary company with a leading position in its markets: construction, property development and concessions. BESIX Contracting specializes in construction, infrastructure and marine works, often in contracts with a high level of complexity. In Benelux and France, the Group’s regional affiliates BESIX Infra, Belemco, Cobelba, Jacques Delens, Vanhout, Wust and Lux TP ensure a strong presence and a local approach.

With Franki Foundations, West Construct, Socogetra, BESIX Environment and Van den Berg, the Group offers specialist niche solutions for the building market like deep foundations, geo-engineering, road construction, water treatment and cable and pipeline construction.

Backed by our experience in our home markets, we have built up strong positions outside Europe. A typical example is the Middle East, where over a 50 year period we have built up an impressive portfolio. This diversification in activities and geography pays off by reducing our risk exposure
