So San Francisco doesn’t go thirsty
05 August, 2010
Like most infrastructure in the San Francisco area, the Crystal Springs By-pass Pipeline can be affected by seismic activity, so the risk assessment of its design, safety and functionality has to take this into consideration. It was decided that the risk, from landslide damage to the pipeline in particular, was too high to rely on the original structure, so an alternative by-pass tunnel was decided upon as just one, but a vital, part of the Water Supply Improvement Progam (WSIP) undertaken by the San Francisco Public Utilities Commission (SFPUC). Maurice Jones reports on its completion.

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

Meeting shotcrete specifications
23 March, 2010
In the long history of shotcrete, or sprayed concrete, linings underground, never has so much been expected of them.
