Indian construction firm J Kumar Infraprojects has won a Rs19.98bn ($280.56m) contract for the Mumbai Metro Rail project in Maharashtra.

Awarded by Mumbai Metropolitan Region Development Authority (MMRDA), the contract includes the design and construction of nine elevated stations and an elevated viaduct.

It also involves construction of one underground station for Mumbai Metro Line 9, two flyovers and an underground twin tunnel.

The Letter of Acceptance (LOA) awarded by the MMRDA excludes architectural finishes and PEB roof structure.

Line 9 is an extension of Mumbai Metro Line 7, which runs from Dahisar to Mira Bhayander and Andheri to CSIA. It is 13.581km long.

J Kumar Infraprojects is a Mumbai-based company that primarily deals with the design and construction of flyovers, bridges, subways, skywalks, roads and other related projects.

In December last year, Indian Prime Minister Narendra Modi laid foundation stones for two metro lines to be built with an investment of Rs150bn ($2.12bn) in Mumbai.

The two metro projects, Thane-Bhiwandi-Kalyan (Metro-5) and the Dahisar-Mira Bhayander (Metro-9) are executed by MMRDA.

In April, a consortium led by DB Engineering secured a project management and construction management services contract valued at $2.26bn for Mumbai Metro Line 4 from the MMRDA.

As well as DB Engineering, the consortium includes Louis Berger and Hill International.

Connecting Wadala in central Mumbai to Kasarvadavali, the 32.3km-long Mumbai Metro Line 4 will feature 32 stations.
