Robbins has received an order from Impregilo for three hard rock TBMs to construct almost 65km of tunnels on the Kárahnjúkar hydro-electric project in Iceland.
The order includes a 7.6m diameter refurbished machine, and two new 7.2m diameter machines. They will be fitted with Robbins 482.6mm cutters, which were successful on the record-breaking Little Calumet Leg tunnel in Chicago, US (see T&TI June 2003, p9).
The Káráhnjúkar project was highlighted by this magazine in December 2002 (p6). Impregilo won the US$603M contract in February this year, beating off competition from Balfour Beatty and Hochtief, among others.
