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.

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 60 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.
