Ensuring the correct lifting strategy is vital to the success of any tunnelling project, reports technical journalist Bernadette Ballantyne.

Crossrail in practice
10 October, 2013
As Crossrail, Europe’s largest civil engineering project, reaches the advanced point of construction, Simon Pugh, lead engineer in the route Control Centre for Crossrail presents to the BTS and Minsouth audience about how it is built and how it will be run

Facing the future
25 September, 2013
The population of London is expected to reach 10 million by 2030, and the future of the Underground is crucial to supporting this growth. Neil Moss, principal tunnel engineer, and Keith Bowers, profession head for tunnel engineering, both of London Underground, review possible future developments in the near future

Funding Gap
25 September, 2013
Highlights such as the Jubilee Line Extension stand out from the economic mire of the past 50 years. The second half of the 20th century was not kind to a Britain newly stripped of superpower status, or the capital’s metro, which following WW2 entered a half century of neglect and underinvestment

Going under
25 September, 2013
The growing use of microtunnelling in Ontario in the 20 years leading up to the Millennium shows the region’s underground industry keeping pace with developments worldwide. Seamus Tynan of Ward and Burke Microtunnelling presents this brief history from 1980 – 2000

War and Peace
25 September, 2013
As the world lurched into the most bloody period in history, London Underground entered a golden era of management and vision. Historian James Chappelow continues the story up to the years of decline

A Muddle or a Miracle?

This year’s BTS Harding Prize was awarded to David Clayton of Morgan Sindall for his paper on the TBM crossing at the Lee Tunnel conection shaft. This is part one of his paper.

Invisible options
21 June, 2013
As urban infrastructure moves underground, SEM has proved to be a very flexible tool to construct complex underground structures. With blasting restrictions in many cities, roadheaders are providing reasonable production rates combined with low noise and vibration levels. Enrique Fernandez and Alejandro Sanz, both of Dragados, and Juergen Laubbichler of Dr. Sauer & Partners, explain why the industry should consider SEM in urban environments.

Sprayed overbridges
06 June, 2013
SCL overbridges at tottenham court road. Andreas Feiersinger of dr. Sauer & partners, and Phillip Lea of Halcrow were the authors of this paper, which was presented at the March meeting of the british tunnelling Society

Studying stress
04 June, 2013
An extensive parametric study was performed to analyse the effect of tunnel lining stiffness on the stress distribution around shallow tunnels. Hany El Naggar and Taylor Steele of the Department of Civil Engineering, University of New Brunswick in Canada, share the results

Bond street models
16 May, 2013
Congested Bond Street Station at the heart of London's Underground is one of the key challenges for an upgrade project. Ali Nasekhian, Thomas Schwind and Stefan Pinter of Dr Sauer explain 3D modelling for the project

Practical modelling
16 May, 2013
This paper attempts to offer practical information and disclose significant aspects of numerical simulations in tunnelling based on the authors' experiences in research and applications on a wide range of projects in and outside the UK. authors Panos Spyridis of dr. Sauer, Angelos Gakis of dr. Sauer and Anmol Bedi of imperial college london explore

Under fire under work
13 March, 2013
The risk of fire in tunnels under construction can be reduced in several ways. At the November 2012 BTS meeting Barry O’Donoghue, Mott MacDonald site contract manager; Francois Pogu, Vinci's Lee Tunnel project director; Dave Bulbrook, London Fire Brigade group manager; and Donald Lamont of Hyperbaric & Tunnel Safety reviewed the Storbelt and A86 Socatop tunnel fires, protocol for working with fire brigade and current legislation required for contractors.
