Forecasting tunnelling behavior
26 August, 2011
Most rock characterisation and ground behaviour prediction has concentrated on TBM drives, but the authors of this paper go into forecasting tunnel behaviour for feasibility and planning purposes when using conventional tunnelling methods, using new methodology from Spain. Prof Richard Z T Bieniawski of US-based Bieniawski Design Enterprises, David Aguado and Benjamin Celada of Geocontrol and Alejandro Rodriquez CDIAM (both companies in Spain) present the argument

To deal with tight deadlines and unique ground conditions, the City of Portland’s choice of a non-standard contract will pay off as the final drive of the Balch Consolidation Conduit completes this month. Nicole Robinson looks at the challenging soil in northwest Portland

Perforating the Pacific
13 June, 2011
Fairytale projects are being put to tender. Underground defences against drought and flooding, surface to seabed drives through magnificent artificial islands and socio-economic unity through high-speed rail. The tunnelling industry in South East Asia refuses to be eclipsed by the mammoth markets in India and China. Alex Conacher explores the latest trends

Helsinki airport link tested to extremes
13 April, 2011
The construction of the 18-km long Ring Rail Line began in May 2009. An 8-km twin tunnel under Helsinki-Vantaa International Airport is under construction. It requires the excavation of about 1,500,000 cubic metres of rock. So far 80 per cent of this work has been completed in five separate contracts. The Ring Rail Line project is being conducted under the direction of the Finnish Transport Agency. Cooperation partners are the City of Vantaa and Finavia Corporation. Traffic will start in 2014, Merja Vilska, spokesman for the Ring Rail project reports

Channel Tunnel risk profile for policy
13 April, 2011
This article is based on a the presentation by Richard Clifton to the 2nd Annual Fire Protection and Safety in Tunnels Conference held in Milan, Italy, in October 2010. The presentation was entitled ‘Case Study: An exploration of Channel Tunnel design and operation, factoring in risk profile, to assess key safety policies’. Richard Clifton is chairman and head of the UK delegation to the Channel Tunnel Safety Authority within the Office of Rail Regulation, UK

In the mix on site
11 February, 2011
There are many considerations when deciding how to supply the concrete necessary for lining and support in most tunnelling projects. Not least of these are how to source large volumes of material on site, and to deliver it to the location of use. With usually restricted surface space, and often long transport distances, this is no easy task. Maurice Jones checks on some developments to make it easier

Change: Its evaluation and how to avoid disputes
18 January, 2011
Following on from last month’s Change: Project & Legal Perspectives, P Greenwell and M Mills of Navigant Consulting consider the evaluation of programme and quantum aspects of change in respect of live tunnelling projects. The authors identify common pitfalls which can so often mean that ‘change’ and ‘dispute’ have become almost interchangeable
