UK ENGINEERS will be at the forefront of efforts to build New York City's first subway system for over 30 years.
British tunnelling engineers from Arup and Aecom-owned Maunsell will be drafted in to work on the £8.25bn 2nd Avenue Subway in Manhattan after an Arup/Aecom joint venture won the detailed design contract.
Aecom subsidiaries Maunsell and DMJM-Harris will work closely with Arup in an integrated team for client New York City Transit Association.
'Maunsell will play a major role in the scheme with our international expertise in tunnel and station construction, ' said Maunsell tunnelling director Anthony Umney.
The 13km line will have at least 15 stations between 125th street in north Manhattan and the the southern tip of the island.
Ground conditions will vary from hard rock to mixed soft ground requiring tough boring procedures.
Most of the tunnelling will be bored to minimise disruption on the surface. Cut and cover tunnelling will only be used for the stations.
Detailed design work is set to start after the New Year and the 12 year construction period is expected to start in 2004. DMJMHarris president and chief executive John Dionisio insisted that the project would proceed on time despite fears that September's terrorist attack on the World Trade Center would cause delays.
