Where the purchaser entrusts all or part of the design of the works to the contractor, the contract performance conditions must include the obligation to identify a project management team responsible for designing the works and monitoring their implementation.
When the purchaser entrusts the contractor with only part of the design of the works, he may himself, by way of derogation from the obligation set out in article L. 2431-3, call on a team of project managers for the part of the design that he assumes.
