E-mail henrysnow@crossrail.co.uk 06/03.The UK government has revealed that the cost of Crossrail had risen to up to £15 billion and that it would take more than a decade to build. Transport secretary Alistair Darling said the plan to build Crossrail could be delayed by a further round of public consultation. This would mean Crossrail would not be built before the 2012 Olympics, which could hold back a bid by Britain to host the event. The east-to-west link includes twin 9 km mainline rail tunnels under London linking Paddington and Liverpool Street stations. They would cost about £5 billion. Crossrail would also include two branches east of Liverpool Street to Stratford and Docklands, with options to take the lines on to Ebbsfleet and Shenfield. The Department for Transport refused to say why the costs had grown by almost 50% but the Treasury is treating estimates with great scepticism after being forced to fund huge cost overruns on the Jubilee Line extension and the Channel Tunnel rail link.

Enbridge has selected two contractors for the Great Lakes Tunnel Project. Great Lakes Tunnel Constructors - a partnership between Jay Dee Contractors from Livonia (Michigan), and the U.S. affiliate of Japanese tunnel construction firm, Obayashi Corporation - will construct a 6.4 km (4 mile) long tunnel, about 30.5 m (100 ft)  below Lake Michigan, this will house a new Line 5 in the Straits of Mackinac. The new tunnel will replace the underwater segment of Line 5,  twin pipes that have lain across the bottom of the Straits of Mackinac in northern Michigan since 1953, running between Superior, Wisconsin, and Sarnia, Ontario.

Enbridge has also selected Arup (London) to deliver construction design documentation for the Great Lakes Tunnel Project.

The Great Lakes Tunnel Project  will enable residents, schools and businesses to continue to receive critical fuel and the thousands of products.  Line 5 helps make this possible while increasing environmental safeguards and protection of the Great Lakes.  Line 5 each day carries 23 million gallons (87 million litres) of crude oil and natural gas liquids used for propane between Superior, Wisconsin, and Sarnia, Ontario. Construction of the Great Lakes Tunnel Project will begin in 2021.

Following approximately two years of construction, Enbridge expects to place the new Line 5 segment into service in 2024. Visit https://www.enbridge.com/media-center/media-statements/enbridge-selects-contractors-for-great-lakes-tunnel-project.

  While the West Side CSO tunnel is under construction to reduce sewage into the Willamette river, the 9.15 km East Side CSO tunnel is under design. Currently, the planned interior diameter of the tunnel is approximately 6.7 m while the outer diameter of the tunnel is approximately 7.6 m. The final size of the tunnel and the liner are still being evaluated and have not been finalised yet. The tunnel is planned to be excavated through the use of a pressure face TBM to maintain face stability and minimise ground losses in the soft ground conditions. Two types of closed face TBMs were identified for potential use on this project: slurry face and earth pressure balance machines. It is currently assumed that two TBMs would be used to complete the project. The two TBMs that are being used for the West Side CSO tunnel would not be used on the East Side due to their different diameters. The lining is expected to consist of bolted precast reinforced concrete segments. The mucking-out technique has not yet been evaluated and will be dependent on the selected tunnelling equipment. Options for discharge and transport of excavated material include conveyor, truck, barge and/or rail. The five shortlisted JVs are Bouygues / Traylor / J.F. Shea; Flatiron / Wayss & Freytag / Fluor; Impregilo / S.A. Healy / Obayashi; ESCSO Tunnel Constructors which consists of Morgan Est, Arup and Soletanche Bachy; and Kiewit / Bilfinger Berger. A Notice to Proceed to begin construction of the project is anticipated to be issued to the selected contractor in January of 2006. It is currently estimated that tunnelling would begin on May 2007 and end on July 2010. More in E-News Weekly 40/2004.

Visit www.mta.nyc.ny.us/planning/sas/index.html 04/02.Vollmer Associates has been selected by MTA Capital Construction Corporation (MTACC) as the prime design consultant on the design/build team of Schiavone Construction and Granite Halmar Construction, a joint venture for the new South Ferry terminal structural box. The project consists of design and construction of the structural box for the new South Ferry station on metro line 1 in lower Manhattan. The new terminal station will consist of two tracks and a 10-car-length centre island platform. The station will replace the existing substandard 5-car length station. The proposed approach tunnel and station will be constructed underneath three existing metro tunnels. Valued at over USD200 million, the project begins with modifications to be made at the existing metro tunnel under Greenwich Street, north of Battery Place so that the new tunnel can diverge to the west and proceed beneath a portion of Battery Park and then cross beneath the existing tunnel approach to the South Ferry loop tracks, and beneath the Line 4/5 metro tunnel to Brooklyn. The new station alignment will continue adjacent to State Street and terminate under Peter Minuit Plaza in front of the newly constructed Whitehall Ferry terminal. When completed in 2007, the new station will allow increased throughput and therefore increase the overall capacity of the entire 7th Avenue/Broadway Line.
