Astm: $864 million contract in San Francisco for seismic retrofitting of the Golden Gate Bridge
Through its US subsidiary, Halmar International
(Il Sole 24 Ore Radiocor) - Halmar International, the US subsidiary of the ASTM Group – the world’s third-largest operator of motorway networks under concession, and a leader in major infrastructure projects and infrastructure technology – has been awarded the contract for the seismic retrofitting of the famous Golden Gate Bridge. This is the bridge linking the city of San Francisco with Marin County to the north. The project, commissioned by the Golden Gate Bridge, Highway and Transportation District, is worth $863.9 million and is the first construction contract awarded for the final phase of the Golden Gate Bridge’s seismic retrofitting. The project aims to reinforce the bridge’s structure to ensure it can continue to serve as a vital transport link and reopen swiftly to allow for emergency response and the restoration of traffic in the event of a major earthquake of a magnitude comparable to that which occurred in 1906 along the San Andreas Fault.
