Jakarta MRT's boring job begins next week

JAKARTA - Mass rapid transit (MRT) project operator PT MRT Jakarta on Thursday officially named Metro One Consortium, a consortium of one Indonesian and three Japanese companies, as the winner of the MRT railway system and track work tender.

The tender was the last one for the construction of the first phase of the MRT's south-north corridor, which is set to connect Lebak Bulus in South Jakarta and the Hotel Indonesia traffic circle in Central Jakarta.

Present for the event were president director Dono Boestami and representatives from consortium members, namely Japanese companies Mitsui & Co., Ltd., Toyo Engineering Corporation, Kobe Steel, Ltd. and Indonesian company PT Inti Karya Persada Tehnik.

The contract signing was witnessed by Japanese Ambassador to Indonesia Tanizaki Yasuaki and Jakarta Development Planning Board (Bappeda) head Tuty Kusumawati.

"The signing marked the conclusion of all of the [construction] package contracts. I hope that the project will be completed as scheduled and I also wish your support so the project will run smoothly," he said, adding that the consortium will have to complete its job, including a trial run, within 185 days.

The ¥15-billion (US$175 million) contract comprises the procurement of substation, overhead contact, power distribution, signaling, telecommunications and automatic fare collection systems, platform screen doors, escalators and elevators, as well as a facility for supervisory control and data acquisition, and track work.

"We will use the latest signaling technology, namely communication-based train control or CBTC. The system is expected to improve the train trip in accordance with scheduling and safety standards," he said.

MRT operational and maintenance director Albert Tara said the MRT operations would be controlled entirely by the control centre.

"Our future MRT will still have train drivers to ensure operational safety. They will also be the person in charge [of the train] during emergency situations," he said.

Tetsu Ikeda from Mitsui shared his optimism that the consortium would be able to contribute to the project. "Japan is a leading country in railway systems. I promise to work together to strengthen the project. We will deliver the best quality of Japanese products," he said.

As all of the contract packages have been signed, the MRT construction project will run as scheduled, with the project operator expecting tunnel boring machines to arrive next month.

"Four tunnel boring machines will arrive sometime next month - we are now working on customs documents. We expect to start [underground boring] as early as August," Dono said.

MRT construction director M. Nasir said the underground boring would start from the Senayan Youth Statue in South Jakarta.

"We will place two machines at the statue point and the other two at the traffic circle. They will meet at Setiabudi," he said, adding that the tunneling is expected to be completed within a year.
