Nippon Koei will also be responsible for construction supervision, procurement support and project management for the line which is expected to serve 510,000 commuters every day and will offer a journey time of 36 minutes.
In February the Bangladeshi government signed a Yen 10.48bn ($US 106.8m) loan agreement with Japanese International Cooperation Agency (Jica) for implementation of the metro project, which is part of a Yen 70.69bn agreement for infrastructure projects in Bangladesh. The government will fund the remainder of the $US 2.83bn overall cost of the metro project.
Jica issued its approval for the Nippon Koei selection following the review of three bids by a technical committee comprising officials from DTCA, and Bangladesh University of Engineering and Technology.
DCTA is responsible for building the metro and expects to call international tenders in September 2015 for five contracts covering main line and stations, electrical and mechanical systems, a maintenance depot, depot equipment and rolling stock. The line is scheduled to open in September 2021.
