Therefore, it is estimated that tunneling will follow in mid-2021 till end-2022, to start with the first phase of boring adjacent tunnels, three subway stations beneath the ground surface, and constructing a depot.
For this purpose, Japan International Cooperation Agency agreed with the Philippine government to receive a 104.53 billion yen loan to deliver proposed stations.
Preferred team Shimizu (a JV formed by Shimizu leading contractor, Fujita, Takenaka Civil Engineering, and EEI) secured a $1.05 billion contract in 2019 to build Quirino Highway, Tandang Sora, and North Avenue stations.
