September 2014: TBM systems manufactured for short but technically demanding projects leave with them a wealth of amortization and reserve design-life that is available for redeployment after final breakthrough on the initial project.
The €65 million Herrenknecht mega-TBM system was used at Sparvo to complete twin 15.5m o.d. drives for the 2.5km long highway tunnel in Italy. Jens Classen, Director of the Tunnelling Division for Toto Construzioni Generali, explains the Sparvo project and the availability of the award-winning investment for redeployment.
