Evening Meetings 2005

The BTS has a membership of almost 700 individual and over 60 corporate members. It is one of the most vibrant gatherings of professional tunnellers in the world.


Managing Risk - Tunnelling for Heathrow's Expansion to Meet the 21st Century

Since 2001 BAA and its partners have been planning and delivering Terminal 5 in a single, multi company team environment. A key element of Terminal 5’s infrastructure is 13.5km of tunnels to provide road, rail and surface drainage underground infrastructure. Whilst the majority of the tunnelling has been carried out using TBMs, innovative developments of the single shell shotcrete lined tunnelling method were made for the construction of the numerous short and complex underground structures. Much of the tunnelling was carried out beneath existing critical airport infrastructure and existing railway tunnels. The presentation will share the approach adopted by the Team to address risks associated with project execution, ground movements and safety.

The talk will describe the project, some of the problems and the work that is currently underway on this new, technically challenging and nationally important mining development in Iran, which is being undertaken by a Joint Venture of IRITEC/IRASCO on behalf of state organisation, IMPASCO. Some comparisons will also be drawn between the technology being deployed in the new mine and the traditional mining techniques and technology currently in use in the Iranian coal industry. The Tabas Coal Mine Project involves the detailed design, mine development, procurement, installation and commissioning of equipment from a “green-field” of the first fully mechanised longwall coal mine to be opened in Iran. Having completed the detailed engineering for the mine and the foreign procurement of the new mining equipment, the construction of the Tabas No. 1 Mine is currently underway.

Thames Tideway CSO Interceptor Tunnel Bazalgette Phase II

Bazalgette’s visionary and acclaimed interceptor system resolved the sewage pollution problem of the Victorian era. It also provided the foundation for the successful recovery of the Thames following implementation of the biological sewage treatment in the 1960s and 70s. However London’s combined sewer system, largely unchanged to this day, has insufficient capacity for the high flow from rainfall run-off. Storm flow frequently discharges to the Thames via the CSO (combined sewer overflows) creating pollution, environmental damage and an elevated public health risk. Following some four years of investigation the preferred option is a deep storage tunnel which intercepts and transfers the storm flow to treatment. The presentation will share how the team developed the concept of the storage tunnel option, including the outline design, programme and investigation of construction and geotechnical issues.

Harding Prize 2005

Young Engineers in the Tunnelling Industry will present papers in competition for the Harding Prize. This prize was instituted in memory of Sir Harold Harding, one of the founders of the British Tunnelling Society. The BTS judging panel will have already short-listed the papers on their technical content, quality of text and interest to the tunnelling industry. The papers will cover a range of important and topical projects and technical issues.


Filling the Void: Shaft Stabilization at Strood Tunnel

In 2004 a section of ground collapsed above the brick lined Strood Railway Tunnel, South East England. At this informal discussion we will hear about the design development and construction experience of the team who, in 2004, further investigated the cause, carried out the relining of the Strood and Higham Tunnel and reinstated the surface profile.

Fire Engineering for Highway Tunnels

An informal discussion exploring the issues which lie behind fire engineering decisions both in new build highway tunnels such as the A3 Hindhead Tunnel and refurbishments of existing tunnels such as the Blackwall Northbound bore. Risk analysis, early warning systems, audio and visual communications, fire suppression systems, escape routes and the advantages of taking a holistic approach to fire safety will all be explored in this presentation.

Egnatia Motorway Tunnels: Northern Greece

In 1995 Egnatia Edos AE (EOAE) was set up by the Greek Government to design, construct, maintain and operate the Egnatia motorway and KBR was appointed as the Project Manager. The completed motorway includes 74 tunnels with a combined length of 50km of twin tunnel. Representatives from KBR and Egnatia will give a presentation on the motorway which stretches from Igoumenitsa in northern Greece to the border with Turkey.

Underground Construction 2005 & The SMART Project: A Dual Use Tunnel Kuala Lumur, Malaysia

The SMART Project in Kuala Lumpur combines stormwater and road traffic congestion relief within a single tunnel. A presentation on this unique solution to the dual problems of heavy traffic and flooding.

Victorian Railway Tunnels

How did the Victorians manage to build a lasting railway network that still forms the basis of today's infrastructure carrying 2.75 million passengers daily? Jack Knight's presentation will reveal some of the answers.

Mersey Queensway Tunnel

Originally opened in 1934, the 4 lane Mersey Queensway Tunnel connects Liverpool to Birkenhead beneath the River Mersey. It was recently refurbished to enhance emergency egress. The presentation will give a detailed description of the process from design through to completion.
