First Balfour, in a joint venture (JV) with DMCI, was the first local contractor to be awarded with a design and build contract for the 5.5-kilometer LRT Line 1 North Extension project. The extension connects the existing LRT Line 1 and MRT-3 by constructing an elevated viaduct from the Monumento Station of Line 1 to the North Avenue Station of Line 3 with new intermediate stations and one terminal station.

The project involved the civil and architectural design and construction of the guide ways and stations of the LRT 1 Extension. This included the construction of a 2.66-kilometer elevated guide way from Monumento to Balintawak including the construction of a pedestrian overpass and walkways, the construction of a 2.74-kilometer guide way that spans from the Balintawak to the North Avenue station, and the construction of 2 elevated stations in Balintawak and Roosevelt.

The JV successfully delivered and completed the project on schedule.
