Salini Impregilo, world leader in large, complex infrastructure works, has successfully completed – on time and on budget – the tunnel for Central Subway, a major project to extend a subway line that travels through the heart of San Francisco.
“This work is the latest example of the Group’s engineering experience and ‘know how’ that make Salini Impregilo a benchmark in the sector of complex public works throughout the world, even in countries with a developed infrastructure network like the United States,” said Claudio Lautizi, General Manager International Operations for the Group.
The completion is a milestone for the Third Street Light Rail Transit Project, which when completed will help reduce air and noise pollution as well as traffic congestion in the downtown area.
Central Subway, in fact, comprises a light-rail line that will improve public transportation to and from some of the city’s busiest, most densely populated areas, including the Visitacion Valley and Bayview/Dogpatch.
The total project is to cost $1.6 billion, $ 241 million of which was set for the work done by Salini Impregilo, its U.S. unit S.A. Healy and partner Barnard C.C.I.
The deadline to complete the tunnel portal structure – the last part of the joint venture’s work – had been set for May 15, 2015, but it completed structure, the 1.5-mile twin tunnels and five cross passages one month earlier – much to the satisfaction of the client, the San Francisco Municipal Transportation Agency.
