Our engineering solutions
THE TESTS PROPOSED BY COLAS ENVIRONNEMENT FALL WITHIN THE SCOPE OF THE WORKS DESIGN PLAN (PCT) DETAILED IN THE FRENCH NATIONAL METHODOLOGY FOR MANAGING POLLUTED SITES AND SOILS
In the design study phase, these tests make it possible to understand any residual uncertainties, to secure the selected proposals and to avoid questioning the chosen scenario during the works.
During the execution phase, these tests help to fine-tune dimensioning and thus optimize the duration and limit the costs of the work.
