A $575-million management contract on London’s $22-billion Crossrail project has gone to a team of San Francisco-based Bechtel Ltd., London, Halcrow Group, London, and Paris-based SYSTRA. The team will oversee design and construction of the system’s tunnels under the city for owner Crossrail Ltd., including a 21-km-long twin-bore tunnel under the center of London and six new stations. The award follows last month’s $146-million program management contract win by a team of AECOM, Los Angeles, CH2M Hill Cos., Englewood, Colo., and the U.K.’s Nichols Group.
