NEW MILESTONE FOR CLEM JONES TUNNEL IN BRISBANE - PROJECT UPDATE
22 January 2009
2008 was a big year for the Clem Jones Tunnel (CLEM7) team in Brisbane (formerly known as the North-South Bypass Tunnel), ending with the arrival of Florence, one of two massive 12.4m diameter tunnel boring machines (TBMs) into a previously excavated section of tunnel in Shafston Avenue, Kangaroo Point.
Florence completed her 2.8km journey from Bowen Hills to Shafston Avenue in just nine months, tunnelling under numerous high rises, office blocks, restaurants and bars and 60m under the Brisbane River. The second TBM Matilda was never far behind, breaking through on 14 January this year.
Both machines will now make their way underneath Main Street and on towards Gibbon Street in Woolloongabba, Brisbane. In total, each TBM will complete 4.3km of tunnel and they remain on target to complete their journey to Woolloongabba by mid 2009.
The Project is in good shape with all 3km of roadheader tunnelling complete, almost 90% of the 38,000 tunnel lining segments produced and all 18 bridges at either end of the tunnel substantially complete. Mechanical and electrical fit out crews have moved into the tunnel and have already started to erect jet fans and the other essential services required to operate the tunnel.
The CLEM7 is a joint venture between Baulderstone, Bilfinger Berger and Leighton Contractors (LBB JV).
