In a context where environmental requirements are a key factor in the acceptability of road projects, setting sustainable development objectives is a major challenge for project owners (POs) and project managers (PMs), starting from the design phase but especially during the consultation phase with construction contractors. As part of pavement maintenance and renewal operations on operational motorways, it is crucial to reconcile the requirements of sustainable asset management with growing environmental concerns. There are multiple challenges: ensuring regulatory compliance, securing timelines and costs, but above all, making sure that the environmental measures adopted are clearly understood and effectively taken on board by the contractors that will perform the works. In this context, the preparation of the tender documents is a key phase: the project owner’s environmental commitments must be translated in a clear and practical way. The partnership between the project owner, which defines the project’s environmental commitments, and the project manager, which technically translates them into contractual provisions in the specifications, thus plays an essential role.
