Insuring an industry
01 October, 2002
As a result of some recent high-profile incidents within the industry, insurers have been increasingly concerned that tunnelling was becoming uninsurable in the market. A joint working party, between the British Tunnelling Society (BTS) and the Association of British Insurers (ABI), has since produced a draft Code of Practice that would allow insurers to continue to offer cover. Presentation of the draft Joint Code of Practice to BTS members took place on 4 July 2002, followed by an in-depth discussion

Monitoring restoration on Bucharest's Metro
01 September, 2002
The construction works for Bucharest Metro's 8.4km long Line 4 extension started in 1989, but due to lack of investment funds, were stopped again in 1996. This lead to the dewatering system being shut off on the eastern (Line 1) extension, flooding a 4.7km long section of tunnels and stations. Now completion and rehabilitation of the line is underway, V Beldean, V Ciugudean-Toma, I Stefanescu and O Arghiroiu of METROUL SA, describe the ongoing project works

Changes in the air
11 January, 2002
The effectiveness of compressed air as a ground support technique ensures its place in tunnelling. However, the potential hazards associated with compressed air working mean that practices are evolving, especially borrowing from developments from the diving industry. Donald Lamont of the UK Health & Safety Executive explains
