The Philippine government is planning to further extend its proposed PHP60bn ($1.3bn) Light Rail Transit Line 1 extension project to Imus and Dasmariñas, instead of ending in Bacoor in the Cavite province.

The Philippine Department of Transportation and Communications (DOTC) will conduct a feasibility and engineering study on the plan to extend LRT 1 to Dasmariñas before making a proposal to the National Economic and Development Authority (NEDA).

DOTC Transportation Secretary Mar Roxas said that the government is studying the Dasmariñas extension because it doesn’t want to waste time.

"If we approve the project then we can easily add it on to the Imus extension," Roxas said.

According to officials, the study will not delay the ongoing bidding procedure for the $1.3bn project to extend the LRT 1 from Baclaran in Pasay City to Niog in Bacoor.

Under the Cavite extension project, the existing 20.7km LRT Line 1 running from Roosevelt, Quezon City to Baclaran, Pasay, will be extended by 11.7km to Cavite.

The extension includes the design, procurement, engineering, construction, installation, completion, testing and commissioning of the 10.5km elevated and 1.2km at-grade extension to Cavite and eight stations, plus two future stations.

The project involves the operation and maintenance of the existing system, which is 20.7km long and has a loop time of 106 minutes, passing through 20 stations including Quezon City, Caloocan, Manila, Makati and Pasay.

Under the project around 39 new light rail vehicles will be purchased to increase the capacity of the line.

The bid submission deadline for operating and maintaining the entire length of LRT 1 has been changed by the DOTC from 22 August to 28 September 2012, and the winner is expected to be announced in 2013.

The winning bidder will integrate the existing system with the new extension, which includes train control and signalling, communications and the power supply network along the 31km line.
