Major road projects

The Group's road construction and maintenance units perform a very large number of small-scale projects, as well as contracts of greater size and complexity.
These larger projects can be carried out in the form of complex contracts such as concessions, P3 (Public Private Partnership), PFI (Private Finance Initiatives) or ASC (Asset Support Contracts). Colas may also take a stake in concession companies, most of the time minority interests, on highway and airport infrastructure, freeways and public transport.
The Group created Colas Projects, an entity dedicated to managing major projects, to provide local Colas companies with expertise in studies and roll out.
