UK’s ability to muster resources
23 March, 2010
With a heavy programme of tunnelling work ahead of it, the UK industry gathered in the ICE Telford Theatre in December to debate its ability to rise to the challenge. Hosted, appropriately, by the BTS Young Members, a packed audience of all ages and affiliations discussed an issue that has generated significant discussion among junior and senior members and is encompassed by the motion: This house believes that the UK tunnelling industry has the sufficient range of engineering expertise and resources to meet the challenges of future projects. As the meeting unfolded, nationalism, internationalism, ageism, and historic reference, all came into the discussion as Neville Harrison (Consultant) and Harnaik Mann (Arup and Vice-Chair of the BTS Young Members committee) proposed the motion and Jon Banyai (Mott MacDonald and Chair of the BTS YM Support Group) and John Edwards (Morgan Est) presented the opposition

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

Running like clockwork

In 1896 Glasgow became the third city in the world after London and Budapest to build and underground transport system. Indeed, such was the public's excitement when Glasgow District Subway Company opened its new underground cable-traction railway that several people were injured and the line had to be closed for five weeks. Jim Shipway describes the original scheme together with a brief review of subsequent modifications
