Agent Access 
Since the preliminary design phase (2003), TERRASOL has been ensuring the Project Management of the geotechnical soil testing campaigns on section C of this High Speed Railway Line (1st phase: packages 5, 6 and 7), between Saulnot and Montreux-Château in France.
TERRASOL assignment consisted in:
- Identifying the geotechnical data required to optimise the design;
- Supervising the soil-testing contractors during their on-site works, including check of compliance with safety rules and RFF (owner) procedures;
- Checking the soil-testing quality and ensuring it matches the geology and project issues;
- Managing administrative and economic aspects of the contracts.
This assignement proved to be most interesting and sensitive due to:
- management of several contractors at a time, as well as of various other specialised participants;
- difficult access to boreholes locations;
- coordination with local residents and local authorities;
- large volume of data to collect, check, and analyse;
- large panel of soil-testing techniques used for the project, due to the variety of issues to deal with: tunnel, earthworks, engineering structures, search for materials, hydrogeology, karstic risk, seismic risk, etc.
Terrasol’s achievements:
- Definition and adjustements of the soil-testing programmes
- Project management of the soil-testing compaigns
- Geotechnical follow-up of experimental structures
- Analysis of availlable data
