Six tunnel boring machines (TBMs) for the Metro Manila Subway Project (MMSP) will be operational by the end of 2024, Transportation Secretary Jaime Bautista said in a press briefing on July 5.

Four TBMs are already operating for the project’s Contract Package 101 — which is composed of four stations in the north, namely, Quirino Highway Station, Tandang Sora Station, North Avenue Station, and East Valenzuela Station.

Bautista said the Department of Transportation (DOTr) is working with the Japanese government to add more TBMs to speed up the construction of the subway, expecting at least 19 TBMs to be operating in the ensuring years.

“Next year we’re taking delivery of more TBMs and siguro (maybe) there will be a time almost 19 boring machines (are) working simultaneously para matapos ‘yung project (to finish the project),” he said.

The TBMs will be utilized to complete the excavation for the tunnels and will use a top-down method for the construction of the stations.

Around 1.2 million cubic meters of soil using cut-cover and the TBMs are to be excavated for the partial operability section of the project or an equivalent of 500 Olympic size swimming pools. For the tunnels alone, the excavation will be around 711,000 cubic meters or an equivalent of 285 Olympic size swimming pools.

The DOTr is likewise working with the contractors of the MMSP to fast-track the construction of subway stations.

Itong (In the) Metro Manila Subway ang (the) more challenging part of the construction yung mga (are) stations kasi maraming stations ‘yan (because there’s a lot) —17 stations—‘yun ang pinipilit namin na madaliin ‘yung (we’re trying to rush) completion and we’re working closely with the contractors,” Bautista said.

The first underground railway in the country, the MMSP is a 33- kilometer and 17-station rail line that aims to cut travel time between Quezon City and Ninoy Aquino International Airport (NAIA) from the current 1 hour and 10 minutes to just 35 minutes.

The subway will cut across eight cities stretching from Valenzuela City to FTI-Bicutan in Parañaque City with a spur line to NAIA Terminal 3 in Pasay City.

DOTr targets its completion by 2029. Once operational, the underground railway system can service up to 370,000 passengers daily.

Total project cost is pegged at P488.47 billion to be sourced through a loan from the Japan International Cooperation Agency.
