The joint venture will be responsible for providing construction management services during all tunnelling work and during construction of all facilities and infrastructure including track, rail systems and stations, as well as project controls services throughout the duration of the project, which is anticipated to be completed by November 2013. Visit www.hillintl.com, www.liro.com, www.lemleyinternational.com and www.hdrinc.comThe project will provide transit access to the West Side of Manhattan by extending the line westward from Times Square under West 41st Street and southward along Eleventh Avenue to the southerly terminus at West 25th Street. The planned extension provides 2.2 km of tunnel to accommodate a two-track railroad with two lay-up tracks for the storage of six trains (three on each side). The extension also provides for two new stations: an intermediate station at West 41st Street and Tenth Avenue (Tenth Avenue station) and a two-track terminal station on Eleventh Avenue at West 34th Street (34th Street station). 22/07.The New York Metropolitan Transportation Authority (MTA) has approved a team of Skanska Civil USA, Schiavone Construction Co. and J.F. Shea Construction for a USD1.14 billion contract to build the 2.4 km extension of the subway line 7 to Manhattan's west side. When the contract has been signed, USD400 million will be included in Skanska's order bookings for the fourth quarter. The joint venture is the unique bidder and the job will be awarded in mid-November. Skanska is part of a joint venture named S3 Tunnel Constructors in which Skanska USA Civil and J.F. Shea Construction hold 35% each and the Schiavone Construction Company holds 30%. The team has a 57-month construction schedule to bore a 6.5 m-diameter tunnel through mostly hard rock some 40 metres deep. Visit www.skanska.com, www.schiavoneconstruction.com, www.jfshea.com and www.mta.info/capconstr/7ext/index.htmlThe assignment concerns the extension of the subway line 7 between its current terminus at Times Square and West Side of Manhattan, adding a new station at 11th Avenue-34th Street near the Jacob K. Javits Convention Center. A second station at 10th Avenue-41st Street dropped from the plans, but could be restored if funding can be found. That second station is not included in the contract award. However, a USD450 million option to build a shell for the station was included as part of the contract by the MTA, and must be acted on by the city within nine months from the start of construction, if the city wants to have a station shell built as part of the initial contract.Earlier this year, Skanska was awarded the project to build the first stage of the 2nd Avenue subway line on the East Side of Manhattan. This project is also being carried out by S3 Tunnel Constructors. Skanska's share of this contract amounts to USD126 million. Click us/73. 46/07.

Public Transportation

URS Corporation, in JV with DMJM+Harris, was selected to design Phase III of the Massachusetts Bay Transportation Authority (MBTA) Silver Line in Boston. Phase III consists of bus rapid transit (BRT) tunnels, with provisions for future light rail vehicle (LRV) adaptation, from South Station to New England Medical Center. The Silver Line is the MBTA's fifth transit line on the nation's oldest transit system and the first use of bus rapid transit (BRT). The BRT line will connect Roxbury, the South End and Chinatown to the city's commercial and services core as well as to the emerging South Boston Waterfront District and Logan International Airport.In addition to the tunnel design, the project includes strategic support for Federal Transit Administration submissions, extensive community participation and outreach services, operations, project controls and administration, systems design, station design and development, civil and environmental engineering and planning.URS's Boston office has been involved with the Silver Line project since its inception in the late 1980s, having completed the design for Phase I, and the conceptual design for Phases II and III. For Phase III, URS leads a design team that prepared a conceptual design report and cost estimate for the project. The report provided a conceptual design for the 1,650 m-long Silver Line tunnels from beneath the existing Green Line at Boylston Station to a new portal near Tremont and Oak Streets and for a new Silver Line Station at New England Medical Center. Construction is expected to start in 2006, with operations to commence in late 2010. The estimated construction cost is USD540 million. Visit www.allaboutsilverline.com and www.urscorp.com 04/04.

Railway

The proposed rail freight tunnel that would run under the harbour from Brooklyn to New Jersey has received $2 million in federal funding to complete its Environmental Impact Study (EIS), and then begin preengineering work if the study proves favourable. Estimated costs for the construction of the tunnel range from $1 billion to more than $2 billion, based on the number of tracks that would run through the tunnel. One- and two-rail options are being explored. Read E-News Weekly # 46. 09/03.

Brushy Creek Wastewater

The Austin-based Lower Colorado River Authority has begun work on a 2.1 km-long 2.8 m-diameter tunnel for a wastewater treatment plant in Williamson County. The TBM-driven tunnel runs from downtown Round Rock off State Highway 79, under I-35 and continues west of the Georgetown Railroad to connect previously installed upstream and downstream portions of the Brushy Creek Regional Wastewater System. The tunnel is needed for a 27.3 km system that will extend from the Cedar Park Wastewater Treatment Facility to the Brushy Creek Regional Wastewater Treatment Plant, adjacent to Highway 79 just east of the Dell Diamond. The tunnel will be constructed in a stiff, expansive clay and a competent limestone. A complex fault zone marking the contact between the two formations will be crossed. Tunnelling is expected to end in August 2003 and the Brushy Creek Wastewater System Project is to be completed by October 2004. Design by Brierley Associates and PBS&J. Visit www.lcra.org 39/02.

Cleveland Sewage

Proposal by the Northeast Ohio Regional Sewer District to build 64 km of tunnels and sewers as part of a $519 million project to clean up Lake Erie. Tunnels would be 1.8 to 7.3 m in diameter with 23 km from E. 55th St to E. 185th St and under the University. Time frame spread over 25 years or more. 48/01. The regional sewer district plans to build 35 miles (56 km) of sewers and storage tunnels as part of a $371 million project to reduce pollution flowing into the Cuyahoga river and several tributaries. The project is the fourth and last that the regional sewer district has developed over the past eight years to control the amount of both sanitary sewer waste and storm water that goes into Lake Erie, the Cuyahoga and other Greater Cleveland's waterways. The project will replace aging sewer systems on Cleveland's south side and in Brooklyn, Newburgh Heights, Cuyahoga Heights and Linndale. Two deep sewer tunnels are the centrepiece of the southerly plan, which cost $8.5 million. They will collect and hold 100 million gallons (378 million litres). Work to start in 2007 and to be done over 30 years. 26/02.With more than 120 km of tunnels built over a span of 30 years, the Northeast Ohio Regional Sewer District (NEORSD) is one of North America's more experienced agencies in tunnel design and construction. The NEORSD has selected Hatch Mott MacDonald (HMM) to design the Euclid Creek storage tunnel project, the largest diameter tunnel in their conveyance network to date. The tunnel will store 208.2 million litres of combined sewer overflow along a 4.8 km alignment and will range from 7.3 to 8.5 m in diameter. The tunnel will discharge by gravity into a future pumping station at the Easterly wastewater treatment plant. The project will help limit and control CSO discharges to Cleveland's east side creeks, streams, and Lake Erie. Project facilities will include numerous construction shafts, diversion structures and drop structures, and 1.6 km of near-surface consolidation sewers. Design completion is targeted for June 2007, with start of construction expected in early 2008. Visit www.hatchmott.com and www.neorsd.org 30/06.
