The use of public-private partnership (PPP) to award projects on design, build, finance, operation and maintenance (DBFOM) basis, is legally possible in France since 17 June 2004, but the projects have to be complex or urgent. In this case, according to the decision, the project is not complex enough to be awarded through a PPP on DBFOM basis.
Additionally the project was awarded after developing feasibility studies. Therefore this project cannot be classified as urgent.
