Water through the Badlands
06 June, 2000
Seventeen million people in the 27 cities served by The Metropolitan Water District (MWD) of Southern California consume a lot of water. The Riverside Badlands Tunnel is part of the MWD's Inland Feeder pipeline project, a vital water supply link to the recently completed Diamond Valley Lake Reservoir, which doubles the surface water storage capacity in the region. Daniel Tempelis, MWD's programme manager for the Inland Feeder Project, and John Townsend, Associate of Hatch Mott MacDonald , report on the $1.2bn development which will supply 1150M litre of water per day to the reservoir through a 70km of 3.65m diameter pipeline.

All systems go in Singapore
30 March, 2000
Traditionally, the underground construction industry in Singapore has been more concerned with the successful delivery of infrastructure projects than blowing its own trumpet. However, with the volume of investment now under way in this small island state and a rolling programme of schemes earmarked for the next three decades, there is huge interest in the tunnelling market here. Editor Steve McCormack was invited by the Land Transport Authority to visit key contracts in progress.

North-south in Berlin
25 January, 2000
Changes to design and the near catastrophic flooding of a main tunnel caisson have resulted in the construction of central Berlin's missing transport route - the north-south rail link - slip from its original planned completion of 2002 to latest estimates of 2005. However, with the start of the final set of TBM tunnel drives, Lot 3 construction supervisor Lahmeyer International believes the project is now on the home stretch.
