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.

Bangkok MRTA: Chaloem Ratchamongkhon Line
10 November, 1999
Six EPB machines from Kawasaki and two from Herrenknecht are now boring running tunnels for the Chaloem Ratchamongkhon Line in Bangkok. While the tunnel drives are generally in favourable ground conditions - stiff clay and dense sand - the EPB mode is usually being maintained to limit ground settlements. Dr Doug Maconochie, Senior Manager, Sverdrup Civil Inc., and Sutchavee Suwansawat, doctoral candidate, Massachusetts Institute of Technology, report.
