ABSTRACT
The contract for the construction sites CO6 & CO7 of the Lyon-Turin railway link (TELT) has been awarded to the Vinci Construction Grands Projets and Webuild consortium.
Works involves constructing 46 km of tunnels through diverse geological conditions, utilizing 3 TBM excavation faces and up to 9 traditional excavation faces across two operational sites (CO6 and CO7).
Over five years, a total of 10 million tons of soil will be excavated. These materials are transported from tunnel fronts to the surface and temporary deposit sites via a network of conveyor belts.
Upon formal reception at the surface level, the operational teams of CO11 are responsible for valorizing all excavated soils from all the lots on the French side of the TELT project. Additionally, CO11 is responsible for supplying the concrete aggregates to the TELT working sites.
The efficient valorization and reuse of excavated materials require precise identification and tracking of materials from each tunnel face, considering factors such as tunnel structure, geology, mechanical characteristics, and timestamps. This traceability must also comply with France’s new environmental regulations (Digital Register RNDTS), effective since 2023.
Given the volumes involved, the simultaneous activity across multiple tunnel faces, the complexity of data collection and correlation, and the need for timely dissemination of pertinent information to various stakeholders, handling such a substantial volume of data quickly becomes technically challenging.
This presentation details the solutions implemented to address these traceability challenges efficiently. By utilizing automated digital tools on-site and an online digital platform capable of integrating and harmonizing in real-time multiple sources of information, the solutions meet stakeholder’s expectations and facilitate the preparation of mandatory reports such as environmental impact, carbon footprint, quantitative data, geological monitoring, among others.
