AECOM/Arup jv appointed for engineering services on £5.6 billion Second Avenue Subway System project in Manhattan, accelerated after the events of 11th September, 2001. New 13 km subway line with 15 stations to run under east Manhattan from 125th Street to the Battery at the island's southern end. Both cut-and-cover and bored tunnelling in clays and hard rock with connections to unused tunnels built in the 1960s. Visit www.aecom.com and www.arup.com 45/01. Plans for a Second Avenue subway line from Harlem to the southern end of Manhattan include 16 stations, several connections to other trains and a spur in midtown to link with lines running along Broadway. A preliminary MTA map shows the northern terminus of a Second Ave. line at 125th St. and Lexington Ave., with connections to the 4, 5 and 6 trains and the Metro-North Railroad. Stops would be at 116th, 106th, 96th, 86th, 72nd, 54th-57th, 42nd, 34th, 23rd, 14th, Houston and Grand Streets., followed by Chatham Square. Two more stops south of the Brooklyn Bridge would follow, but the locations have not been determined. The federal government has allowed the MTA to begin preliminary engineering. Project to involve cut-and-cover construction but officials underground boring to be used as much as possible. Construction time estimated at 15 years for a cost of $12 billion. Begin of construction by end of 2004.

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.

Shea Construction (25%) has been contracted by the Metropolitan Transportation Authority (MTA) to manage and carry out construction of the new Second Avenue subway line in New York City on Manhattan's East Side. The contract amount is USD337 million. The contract is for construction of a 245 m-long by 23 m-wide launch box between 92nd and 95th streets, which will be the future 96th Street Station. Two parallel, 4 km-long train tunnel shafts will be advanced from this box, from 92nd to 63rd streets, using a TBM. Also included in the first contract is the construction of two access shafts at 69th Street and 72nd Street for the construction of the 72nd Street Station. Part of the approximately 100,000 cubic metres of the soil and rock to be excavated is contaminated and must be treated in an environmentally correct manner. Also included in the contract are extensive utility relocation and construction, temporary road decking and an electricity substation. Construction will begin immediately and is scheduled to be completed during 2010. Work on the new subway line is divided into four phases, of which this is start of the first. The Second Avenue line will be a total of 14 km long and relieve congestion on the Lexington Avenue line, which carries more than one million passengers daily. Read E-News Weekly 39/2006.

The Second Avenue subway will include a two-track line along Second Avenue from 125th Street to the Financial District in Lower Manhattan. It will also include a connection to existing subway lines. Sixteen new stations will be constructed.As the construction management consultant, PB will provide resident engineering and inspection services. The firm will be responsible for design/constructability reviews, contract management and administration, project controls, value engineering, utility coordination, maintenance and protection of traffic, commissioning and startup, and project close out. The company will manage the contract interfaces for six concurrent construction contracts.Phase 1 of the project involves construction of twin tunnels from 96th Street to 63rd Street. A tunnel boring machine will bore one tunnel from 96th to 63rd streets and a second tunnel from 96th to 72nd streets. The remainder of the second tunnel from 72nd to 63rd streets will be constructed using the drill-and-blast method. Three new stations will be constructed and the rehabilitation of the 63rd Street station will enable the new line to connect to existing service. This project phase also entails the launch box for the TBMs, two access shafts, and installation/integration of all systems components. Construction of phase one is scheduled for completion in 2013.
