Traceability of Excavated Material—T2A Tunnel
Horizon Grand Paris & TEDELIS
The T2A tunnel project on the south section of the upcoming Paris Métro Line 15 involved building a 6.6 km section of railway tunnel between Villejuif–Louis Aragon and Créteil–L’Échat stations.
This portion of one of the Grand Paris Express lines included three types of earthwork: stations and ancillary structures; cast walls; and tunnel boring, generating over 1.4 million tonnes of excavated waste.
In terms of waste management, the major issue with such a large-scale project was the impossibility of repurposing excavated waste—it had to be disposed of entirely. Furthermore, the companies’ CSR policies and the legal framework pertaining to excavated waste management required them to track all removed material.
