MRT tunneling project to
kick off in August

Carrying out a megaconstruction project like a mass rapid transit (MRT) system in the middle of congested Jakarta is a herculean task, and the hardest part is just about to start.
After two years of construction, the MRT project contractors will begin tunnelling underneath the capital’s thoroughfares from the Hotel Indonesia traffic circle in Central Jakarta to the Senayan traffic circle in South Jakarta in August.
The six underground stations that will be built on the stretch are Senayan, Istora, Bendungan Hilir, Setiabudi, Dukuh Atas and Hotel Indonesia (HI) traffic circle.
Speaking on the sidelines of a recent MRT seminar, city-owned project operator PT MRT Jakarta’s construction director, M Nasyir, explained that the tunnelling would involve four giant tunnel-boring machines (TBMs), which would excavate tunnels between 12 and 24 meters underground. Each machine is 3 m in length and 6.7 m in diameter.
“Compared with Singapore or Kuala Lumpur’s geological characteristics, Jakarta is less complicated because our city does not have as many rocks as they do. We ordered TBMs, which suit our geological condition,” Nasyir said, adding that the machines were designed to limit the disturbance to the surrounding terrain.
The tunnelling process of the 6-kilometer underground section is expected to be completed by the end of 2016, as the machines will excavate tunnels at a speed of 8 m a day.
Kazuya Osako of Shimizu Corp., a project manager for the Bendungan Hilir to Senayan section, said he was confident about the quality of TBMs to be used in Jakarta.
“We have chosen very good machines for the Jakarta MRT project,” Ozako said, adding that the biggest challenge faced by contractors was not technical issues but the lack of experienced construction workers. “We have to train the workers from zero,” he said.
Also speaking at the seminar was Singapore Land Transport Authority (LTA) director Chang Kin Boon, who recounted his experience diverting the Singapore River to make way for the construction of a new MRT line.
“The Singapore River is one of our main tourist attractions and one of our main sources of water, so we had to carry out the project while maintaining the quality of the water by installing turbidity curtains prior to the demolition,” he said.
The Singapore River diversion project began in February 2012 and was completed in July 2014.
In Jakarta, MRT project contractors have had to contend with a water canal in the Dukuh Atas area, as well as a water pipe in the Bendungan Hilir area.
Shigeo Hanaki, the project manager for the HI traffic circle to Dukuh Atas section, revealed that his team would build the Dukuh Atas station 24 meters underground, below the canal.

Jakarta. Mass Rapid Transit Jakarta, the company responsible for constructing the city’s Mass Rapid Transit system, said on Thursday that a tunnel boring machine had arrived at Tanjung Priok port from Japan — six months ahead of schedule.
The arrival will allow construction of Jakarta’s MRT system to start in August.
Dono Boestami, the president director of MRT Jakarta, said the Japanese manufacturer was able to finish the machine faster than initially planned.
“We are completing administrative documents at the port so that it can be deployed as soon as possible at the construction site,” Dono said on Thursday.
The boring machine is the first of four scheduled to arrive by the end of this year.
The MRT will be the first of its kind in Indonesia and the government is eager to have the system functioning by the Asian Games in August 2018.
The construction will connect Lebak Bulus in South Jakarta to Bunderan Hotel Indonesia traffic circle in Central Jakarta with 16 kilometers of elevated and underground tracks.
The second stage of the MRT project will stretch 8 kilometers from the traffic circle to Kampung Bandan in North Jakarta and is set for completion by 2020.
Another MRT track to connect east and west Jakarta is undergoing a feasibility study and the government hopes to start its operation by 2027.
The Jakarta government, which controls MRT Jakarta, and Japanese investors have provided funding for the MRT construction.
