Chemical Monitoring of SBT
by FLANDERA Thomas
Geoconsult is awarded with the CHEMICAL MONITORING OF SEMMERING BASE TUNNEL. Semmering base tunnel is 27,2 km railway tunnel between Graz and Vienna. The complex project is divided in three construction lots, where Geoconsult performed or is still performing different consultancy and supervision works (TSV at SBT 3, site supervision at SBT 1.1, geology at SBT 1.1 etc.).
Until now, chemical monitoring has not been contracted at any construction site in Austria, but is expected to become state of art in the future. The difference to usual hydrogeological monitoring (what is performed at any construction site and common business) is the set of parameters. The list starts with Anthracen and finishes with Perfluorooctanesulfonic acid & derivates (PFOS; organic substances) and metals from Aluminium to Zinc with extremely low limits of determination.
The project duration is 10 years.
