DOTr assures Metro Subway will be flood-proof

National, News

Department of Transportation (DOTr) Secretary Arthur Tugade has assured the projected Metro Manila Subway will be flood-proof, stressing that its contractor has experience in dealing with such problem.

At the recent virtual unveiling of a tunnel boring machine (TBM) for the subway, Tugade said one of the Japanese contractors of the project, JIM Technology Corporation (JIMT), has experience in constructing subways in areas prone to flooding.

“The technology and experience of our Japanese partner construction firms are the assurance, and the perennial flooding has been considered very strongly in formulating the details of the first Manila subway station,” he said.

Tugade noted that Japan’s ground conditions where JIMT has previously helped in the construction of a subway, is worse compared to Manila as their tunnels were burrowed below sea-level.

“The subways in Japan are never flooded and they are using that technology. That is the same technology we will use,” he added.

Japan International Cooperation Agency (JICA) chief representative, Azukizawa Eigo said the Manila project will be a joint venture of Shimizu-Fujita-Takenaka-EEI. The project is expected to directly employ 9,000 workers and indirectly hire some 40,000 to 50,000 more.

Tugade said the Valenzuela City to North Avenue section of the subway stretch will hopefully be operational by December 2021, while the rest of the project will be completed by 2024 or 2025.

In the same event, DOTr Undersecretary Timothy “TJ” Batan said the TBM unveiled was only one of six TBMs being manufactured by JIMT in its factory in Tsurumi, Japan.

“Measuring 6.99-meters in diameter and 95-meters in length, each of these 700-ton TBMs will be used for the partial operability section of the project from Barangay Ugong in Valenzuela City to North Ave. in Quezon City,” Batan said.

He said each TBM is capable of laying down 12 meters of tunnel segments per day, in addition to excavating up to 600 cubic meters of soil in the same time frame.

The 34-kilometer Metro Manila Subway Project will have a total of 17 stations, stretching from Valenzuela to the Ninoy Aquino International Airport Terminal 3 and FTI.
