A £400M Arup-designed cable stayed bridge has been chosen as the best value option for the Gerald Desmond Bridge Replacement Project by California’s Port of Long Beach and Caltrans officials.
A contracting joint venture between US firm Shimmick Construction Company, and Spain’s FCC Construccion and Impregilo was selected on Friday as the “best value” proposer for the design and build project. Leading the design team is a joint venture team of Arup and Biggs Cardosa.
Arup will be providing bridge design services, including structural, geotechnical, seismic, and civil engineering services, along with lighting consulting services.
The Gerald Desmond Bridge is a vital trade and commuter route. But the bridge, built in the 1960s, was not designed to handle today’s traffic volumes and is deteriorating. The replacement project will ensure the safety of commuters and protect Southern California’s important role as a major trading hub.
The project selection team, led by Caltrans, the Port, and the Los Angeles County Metropolitan Transportation Authority, formally opened the financial proposals on 4 May, following a rigorous, months-long evaluation of the technical proposals from three firms that had been pre-qualified to bid on the contract.
A “notice of intent” to award the contract will be given on 14 May to the Port’s Board of Harbor Commissioners. A decision by the board on the actual award of the contract is expected in late June, with detailed design starting soon after the contract is signed. Construction is set to begin in early 2013 and is expected to take five years.
The total cost of the overall bridge replacement project is estimated at about £620M, including site preparation, demolition, and other considerations.
