A consortium of contractors has won a contract worth nearly €2 billion to design and build an extension of Metro Line C in Rome.
Italian firm Webuild will lead the Metro C consortium, in partnership with Vianini Lavori. Webuild’s share of the contract amounts to €673 million. Consorzio Cooperative Costruzioni, Hitachi and construction management firm CMB also form part of the consortium.
The project on the T2 section of the line involves building a 4km stretch of line 25 metres under the Tiber River in the Italian capital, in an area of major archaeological and urban importance.
The work also involves the construction of four new stations: Chiesa Nuova, San Pietro, Ottaviano (interconnected with Line A), and Clodio/Mazzini.
According to Webuild, Chiesa Nuova and San Pietro will be archaeological stations, designed to celebrate the city’s heritage and integrate it with the urban setting.
Webuild said the most technically challenging aspect of the work will involve constructing diaphragms up to approximately 90 metres deep. The consortium also plans to employ technology already tested during the construction of the Venezia Station.
Webuild is already in the final testing phase of the San Giovanni–Colosseo/Fori Imperiali section of Line C, with the archaeological stations Porta Metronia and Colosseo/Fori Imperiali scheduled for delivery in September.
Once completed, Line C will stretch 26 kilometres and include 29 stations, 22 of which are already operational. It will link the southeastern suburbs of Rome to the northwest.
