Finesse in tough environments
10 November, 2010
Technologies employed underground to ensure positional accuracy have advanced at great pace over recent years. The portable computer, data processor and laser have all but replaced the tape, notepad and pencil. These, together with the introduction of lasers as reference axes and the toughening of electronics, have led to major benefits in productivity. Maurice Jones reviews some of the latest developments

Catch up on Crossrail

As contractors await the award of the two main tunnelling contracts for the GBP 15.9bn (USD 24.5bn) mega project, work on the stations is gathering pace. Bernadette Redfern gives this report

Britain’s got tunnels
15 September, 2010
With water projects underway, the industry has Crossrail on the brain and for good reason, it sets the tone for the future of tunnelling in the UK, reports Nicole Robinson

Thin barrier integrity – the easy way?
10 June, 2010
One of the major developments of recent years has been the development of sprayed linings, especially to control potential water make in an operational tunnel and to protect equipment and users from its effects. In this market it competes with many techniques, but chiefly coming up against the use of sheet membrane. So are sprayed membranes making serious inroads into this market and are there any limitations to this deceptively simple idea? Maurice Jones reports on some developments and applications.

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. In the transition in scope from hard rock primary support to soft ground permanent support, shotcrete is now expected to create structures under even more demanding conditions, but still at comparatively low cost. Here technical editor Maurice Jones reviews the state of some developments designed to meet such demands
