Makati city council in Philippines has approved the PHP 178 billion (US$ 3.5 billion) Makati intra-city subway PPP project on July 19, 2019. The project includes construction, operation, and management of an 11-kilometer subway with 8 to 10 stations that will serve two districts of Makati, located in the Metro Manila region of the Philippines. This will be the biggest PPP project for Makati city.

The Philippine Infradev Holdings, Inc., formerly IRC, will be a private partner of the Makati city in this venture. Both parties are set to sign the agreement in the near future. The Makati PPP selection committee will sign the agreement only after the fulfillment of certain conditions raised by the authority. Such conditions include posting of performance security, list, and role of final members of the IRC consortium, company registration documents, and copies of the resolutions adopted by respective boards of directors.

The soil testing was also completed on the same day the proposal went through. The testing shows soil strata is stable and that the project can proceed with no foreseen hitches. The geotechnical survey along the alignment began in December 2018, the survey involved drilling small holes and getting rock and soil samples at 200 points along the alignment. 

The subway project will use a dual-track system and will have air-conditioned, underground island stations that can accommodate up to six-car trains, with room for over 200 persons per car. The subway system is expected to entertain more than 700,000 passengers per day. 

The subway line will connect key points in Makati: Central Business District, Puyat avenues, Circuit Makati, the Makati City Hall, the Poblacion Heritage Site, University of Makati, Ospital ng Makati and the other new business districts within the city.
