The Dywidag International-led JV that has been busy on the Delhi Metro has landed another contract to extend the system with a 3.2km long tunnel and two underground stations.

The US$107.5M contract calls for a construction programme estimated to last 38 months. A target of 2010, before the commencement of the Commonwealth games in New Delhi, is the focus for client Delhi Metro Rail Corp (DMRC).

A TBM will be used for the tunnel while the two stations – Hauz Khas and Malviya Nagar – will be built by cut and cover.

Members of the International Metro Civil Contractors consortium are Dywidag, Samsung, Shimizu and local firms Larsen & Toubro (L&T) and Ircon International. The consortium previously built a 6.5km twin tunnel under a turnkey contract on section MC 1B of the metro.

L&T has two other contracts on phase II of the metro’s expansion, which will see two underground stations built at Udyog Bhavan and Green Park plus 1km of cut and cover tunnel.
