A Yen 35bn ($US 353.8m) contract to construct three elevated sections has gone to a Japanese-Indonesian consortium of Tokyu-Wika and Obayashi-Shimizu-Jaya Construction. Tokyu-Wika has also won two construction packages worth Yen 25bn, while Obayashi-Shimizu-Jaya Construction was awarded a Yen 10bn contact for another section. The first civil works contracts were awarded in June.

"With the completion of the tenders, we are upbeat that the MRT project will be realised," says Mr Dono Boestami, president-director of MRT Jakarta, although the system and rolling stock tenders are still be evaluated.

The 15.2km line will link to the Hotel Indonesia traffic circle with Lebak Bulus in southern Jakarta. It will have a 9.2km underground section with six stations while the rest of the line will be elevated with seven stations. The metro is due to open in 2017, and services will initially operate at five-minute headways. Ridership is expected to reach 420,000 passengers per day after three years of operation.
