Major Project of the Year (over €500M)

Klang Valley Mass Rapid Transit (KVMRT) Putrajaya Line Underground Works

Kuala Lumpur is a sprawling metropolis sorely in need of a sustainable solution to its traffic congestion woes. Everyday thousands of commuters find themselves stuck in traffic, incurring losses in time and GDP. The KVMRT network fills that gap with an extensive, integrated MRT system to access the city center conveniently.
The Putrajaya Line or Line2 is a Malaysian mega-infrastructure rail project located in the heart of its capital, Kuala Lumpur. It is part of a 3-line network known as the Klang Valley Mass Rapid Transit (KVMRT) that will raise the existing public transport modal share of the capital city from 20% to 50% as part of the national Economic Transformation Program.
It will consist mostly of elevated rail outside of the city center. As the city center is highly built-up with high-rise buildings, busy roadways, and overhead infrastructures, the only viable solution to connect the alignment is to go underground.
Tunnelling depth varied between 20 meters to 60 meters, largely due to the presence of other intersecting underground infrastructures like the SMART tunnel motorway and metros.

Tunnel civil works cost : 900 Million Euros
