SERVING URBAN DEVELOPMENT
IN LARGE ITALIAN CITIES
Turin: Past, Present, and Future
Turin, with an area of 130 sq. km and a population of 902,000, is one of the most promising
and innovative Italian cities. Maire Tecnimont has deep roots in the city, which is now the
location of one of its main engineering centres, specializing in the design and construction
of infrastructure, power plants and civil and industrial buildings. The centre dates back to
1937 and the foundation of Fiat’s Construction and Plant Division. It was then incorporated
as Fiat Engineering SpA in 1972, and in 2004 was acquired by the Maire Group, becoming
Maire Engineering. Finally, in October 2008 it was merged into Tecnimont.
Thanks to its long-standing presence in the city, Maire Tecnimont has played an important
part in Turin’s development in recent years.
In 1995 the city began a complex economic recovery and urban development programme
that included infrastructural improvements, new transport systems, brownfield recovery,
restoration of the historical centre, and upgrade of the suburbs. Maire Tecnimont has been
actively engaged in this programme and, in particular, in work carried out for the 2006
Winter Olympics. Examples of the latter include the Palavela stadium used for skating
races, built in the record time of less than 14 months, and the Olympic Village, which
comprised three residential units housing 2,500 athletes and their families with gymnasia
and service facilities. In complex civil buildings, Maire Tecnimont has been involved in the
design of Turin University’s Faculty of Law and Political Sciences. The new layout,
developed by Maire Engineering in collaboration with the architect Norman Foster, is
characterized by flexibility and is capable of responding to the university’s future growth
and transformation.
Maire Tecnimont’s main contribution to Turin development currently is in the
implementation of a state-of-the-art mass transport system.
Turin Metro – Line1 (First Part)
Tecnimont built Italy’s first completely automated (driverless, VAL
technology) underground mass transportation system in Turin. The
project was awarded to the Tecnimont-led Transfima consortium in
2000 and completed in 2007. The VAL (automated light vehicle)
technology provides many benefits to passenger comfort and safety:
optimization of train transit frequency, lowering of vehicle
vibrations, and innovative platform door systems. Finally, the lowerdiameter
tunnels meant that the delivery time of the project was
shortened and construction-related problems and inconvenience
for the city were reduced.
Turin Metro – Line1 (Extensions)
TURIN METRO CONSTRUCTION SYSTEM
In December 2006, Tecnimont signed a contract for 3.1 km extension
of the Turin Metro Line 1. The new route from Marconi to Lingotto
includes six stations (Marconi, Nizza, Dante, Carducci/Molinette,
Spezia and Lingotto), five intermediate pits, a 2.9 km double-track
tunnel with 7.5 metres diameter EPB TBM, and further auxiliary
facilities. The work poses considerable technical difficulties because
of the need to minimize the impact of the construction sites. The line
extension crosses the centre of Turin, where the traffic level is high
and urban activities are concentrated. As consortium leader,
Tecnimont is in charge of procurement, design and construction,
including environmental studies and compliance with health and safety
regulations. By the end of 2008, 62% of the work had been completed.
The whole contract, worth about ¤100 million, will be finished by 2010.
A further extension of the Metro Line 1 from Lingotto to Bengasi,
based on the same VAL technology, should be approved by the city
authorities soon. Under an outline agreement Transfima would handle
system engineering, technology procurement, and construction
supervision. The consortium has also developed a preliminary design
for a western extension of Line 1, from Collegno to Cascine Vica.
