# Makati Intra-city Subway

The Makati Intra-city Subway (MkTr) was a planned underground rapid transit line to be located in Makati, Metro Manila, that will link establishments across the city's business district. The construction of it was planned through a public-private partnership program between the Makati City Government and a private consortium headed by Philippine Infradev Holdings. Proponents of the subway are expected to begin construction by December 2018, and Makati Mayor Abigail Binay projects completion by 2025. The subway will cost $1.8 billion (or ₱90 billion) and is expected to accommodate 500,000 passengers daily. It will also have seven stations, with connections to the existing MRT Line 3 and Pasig River Ferry Service.
Construction of this project was put on hold after the transfer of jurisdiction of the ten EMBO barangays from Makati to Taguig was finalized in 2023. This is because its planned depot and some stations were intended to be located in the formerly disputed area, according to the original proposed alignment, thus requiring a reworking.

## Route

The line will be 7.2 kilometers (4.5 mi) long and will have 7 stations. The terminus will be at Ayala station with connections of the same name of the MRT Line 3 station and One Ayala transport hub.

## History
### Early planning

In 2015, the National Economic and Development Authority approved the construction of the Makati-Pasay-Taguig Mass Transit System Loop, which would have been a 20-kilometer-long underground railway from Bonifacio Global City to Taft Avenue. The project was to be funded through the PPP scheme, but after former President Benigno Aquino III stepped down from office, the project was later shelved.
Preparatory work officially began on December 12, 2018, following a ceremonial drilling ceremony at the front of the Makati City Hall, which is near the site of one of the proposed stations of the subway. The signing of the memorandum of understanding between the Makati city government and a consortium consisting of Philippine Infradev and Chinese firms Greenland Holdings Group, Jiangsu Provincial Construction Group Co. Ltd., Holdings Ltd. and China Harbour Engineering Company Ltd was also held on the same day. Preparatory work included soil testing and feasibility studies of the proposed locations for the subway line's stations.
As of June 2019, 8 out of the 10 proposed stations have been finalized. The two proposed stations along Ayala Avenue are yet to be finalized due to "non-response" from its owners. The proponents have stated that they may divert the subway towards the Philippine National Railways Buendia station or the Mile Long property in Legazpi Village instead. In the interim, the first station would be in the current location of the Makati Central Fire Station, which will be demolished, then towards a Lucio Tan owned property near Circuit Makati, and Makati City Hall. The remaining stations would be located near Century City, Rockwell Center, Guadalupe Bliss Housing in Cembo, BGC-Ortigas Link Bridge, University of Makati and the final station in the vicinity of Ospital ng Makati.
In July 2019, soil testing related to the subway completed as the Philippine Infradev and Makati LGU has signed a joint venture agreement for the project
As of October 2019, the plan to move the terminus of the line to the Mile Long property being redeveloped by the national government along Amorsolo Street has been finalized. Favorable soil test results and the route diversion meant that the cost of the project might go down to as low as $2.5 billion.
A joint venture with Megaworld Corp. was formed to build a common station located in Guadalupe for the subway system and for the planned SkyTrain. In a disclosure to the stock exchange, the Philippine Infradev wholly owned subsidiary, Makati City Subway Inc. (MCSI) has received the term sheet from Megaworld. The joint venture will build access and connections to the MRT Guadalupe Station and the Pasig River Ferry.

### Construction

Philippine Infradev Holdings, Inc. received an Environmental Compliance Certificate (ECC) from the Department of Environment and Natural Resources (DENR) and is looking to commence works before the year 2020. If pushed through, the subway may be completed in 2024, a year ahead of schedule.
On July 20, 2020, the EPC contract was signed and awarded to China Construction Second Engineering Bureau Ltd. (CCSEB) and Shanghai Electric Automation Group for the subway line's construction. Former Philippine Vice President Jejomar Binay and Makati Mayor Abigail Binay delivered their speeches via video conference as gratitude for the project. On July 23, 2020, the right-of-way acquisition has commenced for the project, of which 55 landowners received a total of ₱1,000,000 (US$20,270) as compensation. The affected landowners will receive a total compensation of ₱1.18 billion (US$23.9 million).
On August 18, 2020, groundbreaking for the Station 3's transit-oriented development took place, where former parking lots and transport terminal used to stand. To recall, Philippine Infradev executed an agreement with China Construction First Group Corp. Ltd. (CCFG) to build the Station 3's transit-oriented development. Construction will last for 42 months.
Acquisition of properties is also underway in the vicinity of Makati City Hall, as several homes and structures were closed and demolished. The vicinity, also known as Station 5, has been identified as the project's main construction site, where the tunnel boring machine will be assembled and lowered. On October 25, 2020, a city ordinance was enacted to approve and hasten the Right-of-Way acquisition.
On May 14, 2021, the first of five tunnel boring machine was received by the Philippine Infradev Chairman Ren Jinhua in Shanghai, China from its manufacturer in a simple ceremony. It will arrive in the country once the Station 5 construction site was demolished and cleared up.
On November 8, 2021, the Fiscal Incentives Review Board (FIRB) has approved the grant of tax incentives for the rail operations of an ₱81-billion subway project in Makati City that is expected to begin commercial operations in January 2026.
With Makati losing ten barangays to Taguig in a territorial dispute between the two cities in 2023, the subway alignment will need to be reworked because its depot and a few stations were in the affected areas.
In an interview with the Philippine Daily Inquirer, Makati mayor Abigail Binay mentioned that there have been talks with the private proponents on planning on a different transportation initiative as the subway project is no longer viable to proceed.
In August 2024, Isla Lipana-PwC partner Zaldy D. Aguirre, Philippine Infradev Holdings's independent auditor reported a P44 billion impairment loss in 2023. As a consequence of the High Tribunal's landmark decision in the Makati–Taguig boundary dispute, Infradev incurred P5 billion for its subway unfinished work and P39 billion for intangible assets. The subway project was suspended since 5 stations are currently under Taguig's jurisdiction. Infradev completed the excavation and shoring works of Station 3 (Senator Gil Puyat Avenue, Dela Rosa Street and Urban Avenue).

## Fares and ticketing

The upcoming line was to use a distance-based fare structure and will be charged 20% to 25% higher than the fares of LRT Line 1 and MRT Line 3. A 25 percent premium will bring the subway's rate to about ₱38 (69 U.S. cents) for 10 stops.

## Infrastructure
### Station layout

All stations would have a standard layout, with a concourse level and a platform level. The stations are designed to be barrier-free. All stations will have island platforms with full-height platform screen doors.

### Rolling stock

The line was to operate electric multiple units in a 6-car configuration, with a headway of three minutes.

## Expansion

In the aftermath of the 2019 elections, Antonio Tiu, President of Philippine Infradev has stated that he is open to initiating and entering a similar partnership deal with Makati's neighboring cities for the expansion of the subway system. The cities of Manila, Mandaluyong, San Juan, Pasay, and Pasig were specifically mentioned by Tiu.
With the finalized move of the terminus to the Mile Long property, a 2-hectare (4.9-acre) complex along Amorsolo Street, Tiu has started negotiations with the Calixto siblings, Mayor Emi and Congressman Tony, of Pasay to extend the line up to Ninoy Aquino International Airport, which is only three kilometers away from Mile Long and is slated for redevelopment.
