In preparation for the construction of the much-awaited Metro Manila Subway which will break ground on 27 February 2019, officials of the Department of Transportation (DOTr) led by Secretary Arthur Tugade inspected Tunnel Boring Machines (TBM) in Japan.

Straight from the airport, Secretary Tugade immediately proceeded to... the JIMT Tsurumi Factory in the city of Yokohama, south of Tokyo, yesterday, 19 February 2019.

JIM Technology Corporation is considered as Japan's foremost manufacturer of tunnel boring machines.

Secretary Tugade was joined by Undersecretary for Railways Timothy John Batan, Philippine National Railways (PNR) General Manager Junn Magno, Japanese Ambassador to the Philippines Koji Haneda, and Japan International Cooperation Agency (JICA) Philippines Chief Representative Yoshio Wada.

“The Metro Manila Subway is the Philippines’ first-ever underground railway system. Before, people cast doubts and said it is all but a dream. But, on February 27, we will show them that this is real,” DOTr Secretary Tugade said.

Tunnel Boring Machine manufacturer in Osaka

Today, Secretary Tugade and other key DOTr, Japan Embassy, and JICA officials traveled to Osaka via Shinkansen, and inspected the tunnel boring machines manufactured by Hitachi Zosen in Sakai City.

Hitachi Zosen’s Sakai Works (HZSW) factory has already manufactured 1,300 tunneling machines, and has a track record of 130 tunnels overseas.

During the inspection, HZSW also showed their Neo RISE technology — a no engine power and no human operation rising sea wall that automatically rises to protect any structure from incoming floodwater, which is being considered for installation at the entrances of the Metro Manila Subway stations.

Tunnel Boring Machines — critical equipment for the Subway

A tunnel boring machine is used to excavate tunnels using a circular cross-section mechanism. It utilizes sophisticated technology that minimizes the vibration above ground, as well as ground subsidence or surface sinking. It is a requisite in building subway systems, among others.

The 6.9-meter diameter tunnel boring machine being considered for the Metro Manila Subway weights over 600 tons. In the process of procurement, the machine has to be assembled in Japan for a test run. Upon passing the tests, the machine has to be disassembled, shipped to the Philippines in parts, where it will be assembled again for construction use.

Transportation officials are in Japan to attend a high-level bilateral meeting between Philippine infrastructure and economic teams and the Japanese government to discuss status and updates on PHL-JPN projects in the Philippines.

The Filipino delegation will likewise attend the Philippine Economic Briefing on Friday to brief Japanese businessmen on investment opportunities in the Philippines, including the progress of the Build Build Build Program.

MANILA -- Parts of the tunnel boring machine for the Metro Manila Subway Project have started to arrive in the country.

Department of Transportation Assistant Secretary for Communications Goddess Hope Libiran on Thursday said the cutter head of the boring machine arrived in the Batangas Port last March 28, which will pave way for the start of the tunneling works for the subway system next year.

“Tunneling in between stations with the use of TBM (tunnel boring machine) will start by the second quarter of next year. The digging and excavation for stations will start 4th quarter of this year,” Libiran told reporters.

“After the station boxes are excavated, the TBM will be lowered into the station box so that it can proceed with the boring/tunneling between station boxes,” she added.

Transportation Secretary Arthur Tugade said in an earlier interview with reporters that the project will require the excavation of around five million cubic meters of soil equivalent to 2,500 Olympic sized pools.

A 6.9-meter diameter tunnel boring machine weighing over 600 tons manufactured by Japanese firm Hitachi Zosen Sakai Works will be used for the construction of the Metro Manila Subway.

The 36-kilometer Metro Manila Subway will have 15 stations from Quirino Highway in Quezon City to NAIA Terminal 3 in Pasay City and FTI in Taguig City which will traverse seven localities and pass through three of Metro Manila’s business districts.

The subway system is expected to have its partial operations with three stations namely Quirino Highway-Mindanao Avenue, Tandang Sora, and North Avenue by 2022 with its full operations set in 2025.

It is seen to serve up to 370,000 passengers daily during its first year of full operations with a design capacity of accommodating up to 1.5 million passengers per day. (PNA)

As proof of his determination to push through with the "project of the century" — the Metro Manila Subway Project, Department of Transportation (DOTr) Secretary Arthur Tugade unveiled to the media and the public the major parts of Tunnel Boring Machines (TBM) today, 24 February 2020, in Pasay City.

Together with representatives of the Japanese contractor, Shimizu Corporation, and the Japan International Cooperation Agency (JICA), a presentation was made showcasing the assembly timeline and how the TBMs will help accelerate the construction of MMSP.

"The Boring Machine is manufactured per specific designs. This is designed to what they found on the soil that is to be bored. Hindi 'to 'yung pupunta ka lang sa hardware at bibili ng dalawang boring machine. Hindi ho ganun 'yan. That's why it takes a little bit of time. But the moment it comes and it is assembled, the boring becomes fast and more efficient," said DOTr Secretary Arthur Tugade during the briefing.

"We at the JICA are very much honored to be able to support the DOTr's effort to achieve the comfortable life for Filipinos under the 'Build, Build, Build' program of the Duterte Administration. This project is really PROGRESSING VERY FAST. And this is one of the quickest projects progressing," said JICA Senior Representative Kiyo Kiwabuchi.

TBMs are integral in building the subway as these are used to dig underground and lay the tunnels. They can excavate through a variety of ground conditions, from hard rock to sand.

The major parts of a TBM which were unveiled include the shield jack, cutter reduction gear motor, main bearings and articulation jack.

The DOTr plans to utilize 6 TBMs in the construction of the partial operability phase, or the 1st three stations of the MMSP.



Sabay-sabay nating tunghayan bukas, ika-05 ng Pebrero 2021, ang paglapag ng 74-ton CUTTER HEAD ni KAUNLARAN, ang una sa anim (6) na Tunnel Boring Machine (TBM) na gagamitin para sa pagtatayo ng partial operability section, at una sa dalawampu't limang (25) TBM na gagamitin para sa buong linya ng INCREDIBLE METRO MANILA SUBWAY!
