About the Project
Together with leading partners from the Belgian construction sector, BESIX is contributing to one of the most ambitious infrastructure projects in Belgium: the Oosterweel Link – ROCO Project.
On the Right Bank of Antwerp, we are delivering, among other works, the new Canal Tunnels, deepening sections of the Antwerp Ring Road, and helping create more space for a greener, safer, and future-oriented urban environment.
Through this project, we are quite literally helping to build a healthier, more accessible, and more livable region for hundreds of thousands of residents and commuters.
This is your opportunity to be part of a historic milestone in Belgian infrastructure development.

A multidisciplinary group with over 110 years’ experience.
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. This wide-range expertise enables us to handle every aspect of a project, from financing over designing and building to operating and maintaining.
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, Vanhout, Wust, Cobelba, Jacques Delens and Lux TP ensure a strong presence and a local approach. With Franki Foundations, Socogetra, Sanotec 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 its experience in its home markets, BESIX has built up strong positions outside Europe. A typical example is the Middle East, where over a 55 year period BESIX has built up an impressive portfolio. In 2018, BESIX strengthened its position in Australia by acquiring, through a public takeover bid, all the shares of construction company Watpac Ltd.
In 2018 the Group achieved sales revenues of over EUR 2.5 billion. The Group employs more than 15,000 persons in 26 countries across 5 continents.
