Evening Meetings 2011

The BTS holds monthly evening meetings at the institution of Civil Engineers (ICE) from September to June, generally on the third Thursday of the month. Additional meetings are arranged by the BTS Young Members.


East Side Access Project, New York

The $7.3bn East Side Access Project currently under construction in the heart of Manhattan by the New York Metropolitan Transportation Authority Capital Construction Company is the largest federally funded infrastructure project in the USA. This talk will also present an overview of the multitude of tunnelling methods being used, including the first use of slurry TBMs in New York to excavate the 50,000 linear feet of tunnel.

BTS / MinSouth Joint Event - The Ingula Pumped Storage Scheme

The Ingula Pumped Storage Scheme is currently the largest tunnelling project in South Africa. The location is 400km south-west of Johannesburg and 80km north-east of Lesotho. There are over 12km of tunnels up to 9.4m diameter, 4 shafts (up to 20m dia x 190m deep), 2 large caverns, requiring substantial support. The geology is primarily a relatively weak sedimentary rock, with dolerite dykes and sills.

Green Park Step Free Access

The works included an extension to the existing Ticket Hall incorporating a ramp from the adjacent Green Park directly into the station and the installation of two lift shafts. This presentation will discuss the development of the design and construction of the elliptical lift shaft and stub tunnel using SCL methods. The escalator jacking system and the instrumentation and monitoring employed will be discussed .

BTS AGM + Limerick Immersed Tunnel

BTS Annual General Meeting, followed by: The Limerick Immersed Tunnel. The Limmerick tunnel will provide a new road crossing under the River Shannon. The tunnel comprises five 100m-long immersed tunnel elements, a cut and cover tunnel and approach ramps on each bank.

High Speed Railway Tunnels in Spain

With the opening of the new Levante line, the Spanish High Speed Railway network has become the longest in the world. HSR lines with their demanding alignments require the design and construction of an unusually high number of tunnels, some of which are amongst the longest and most important in the world. This presentation provides information of three good examples of the tunnels recently built in Spain: Guadarrama tunnel, Pajares tunnel and finally Atocha-Chamartín tunnel. This is an evening BTS Presentation being held at the "BTS Underground Conference 2011" on 29th to 30th June 2011. It is a two-day conference being held in the Earls Court Exhibition Centre.

BTS / BGA joint meeting: What do we want from a GBR?

Geotechnical baseline reports or ground reference conditions are increasingly being used in tunnelling contracts in the UK to allocate ground risk and ensure compliance with current industry best practice and perhaps more critically, insurers recommendations. What do clients, designers and contractors expect from a GBR and how do they envisage the document will be used before, during and after construction? The aim of the meeting is to discuss the current status of the use of these documents and to learn from the practical experiences of others. Following short presentations, an active debate is envisaged and the audience will be encouraged to participate and share their own experiences.

Dulles Airport Rail Tunnel, Washington DC

Dulles Transit Partners is responsible for designing and constructing Phase 1 of the Dulles Corridor Metrorail Project. An 11.6 mile extension of the existing Washington Metro to Dulles International Airport. A central feature of the project is the Tysons Tunnel. The Tysons Tunnel is a twin-bore, two-track tunnel 762m in length between portals. The central 534m is being constructed by SCL.

Cleaner Seas for Sussex

In order to treat the 95 million litres of wastewater generated each day by the local residents of Peacehaven, Telscombe, Saltdean, Rottingdean and Woodingdean, along with those of Brighton and Hove a new wastewater treatment works and 11km of new sewer were required. Now substantially complete find out how more than 11km of 1.8m and 2.4m diameter tunnels and associated shafts and pumping stations were successfully completed.
