ABSTRACT
Whether imposed by owners or proposed by contractors, monitoring correctly the environmental impact of construction works is an increasing concern. This requires a system capable to guaranty the detailed traceability of all waste materials from extraction to final destination, including storage, transformations and reuse, which becomes complicate when trying to collect and synchronize data from distinct systems and stakeholders. Construction in France provides an interesting case study in this respect. In 2017, Grand Paris Express imposed a digital tool to track all movements of soils from its projects. In 2022, the country imposed the same for all hazardous waste, and in 2023 for all construction waste, forcing the industry to adapt. Since 2018, Altaroad developed systems to help meeting these requirements. The paper summarizes how to successfully implement such system to the benefit of all partners.
