The Metro Manila Subway Project Details

What are the opportunities for suppliers, contractors and consultants


The main proponent of the Metro Manila Subway Project is the Department of Transportation of the Republic of the Philippines. The details of this article were taken first hand from JICA and DOT.

Can you imagine how many heavy equipment, machinery, power generators, air-conditioners and chillers, building material and escalators this project will entail? Not only the construction and engineering companies will benefit from this massive infrastructure project, but the real estate as well.

Metro Manila Tube

Today it is a Tube, Maybe a Hyperloop in the future.

The Metro Manila Tube or Subway Line 9, formerly referred to as the Mega Manila Subway (Metro Manila Underground Train), is an underground rapid transit line currently under construction in Metro Manila, Philippines. The 28.3-kilometer line, which will run north–south between the cities of Quezon City, Pasig, Makati, Taguig and Parañaque, will serve thirteen stations between the Quirino Highway and FTI stations. It will also serve as the country’s first direct airport rail link, with a branch line to Ninoy Aquino International Airport (NAIA). The line is designed to connect with the other urban rail transit services in the region, including Line 1, Line 3, and Line 7 at the North Avenue Common station which is also currently under construction; the planned Line 8 (PNR East-West Railway); the existing Line 2; the planned Line 5 (Makati Subway); and the existing Metro Commuter Line of the Philippine National Railways.

Construction began on February 27, 2019, and is expected to finish by 2025. It is to be numbered Line 9 on future Manila Metro maps. The project is expected to cost PHP227 billion (US$4.5 billion as of 2017), to be included in the national budget in the following years. It is expected be the most expensive transport project to be undertaken by the Duterte administration. The government of Japan has expressed willingness to help in covering the expenses of the subway, and the first part of a 104.5 billion yen loan was signed by Japan.

The Proposed Metro Manila Subway Project (MMSP)

The Metro Manila Subway Project (MMSP) is the first ever subway project in Metro Manila that will connect North Caloocan or Meycauayan in Bulacan and Dasmariñas in Cavite through the National Capital Region. This is a project proposed by the Department of Transportation or DOTr.

PROJECT PROPONENT

Metro Manila Subway Project is a project proposed by the Department of Transportation (DOTr), the primary government agency that provides the policy, planning, implementation, promotion, development and regulation of the country’s network of transportation.

The Environmental Impact Assessment (EIA) Study was commissioned through Japan International Cooperation Agency (JICA).

SUBWAY: A NECESSARY INVESTMENT FOR OUR FUTURE

  • Eases traffic congestion in EDSA and expansion of transport network eastward
  • Reliable, safe and comfortable transportation for commuters using cutting-edge technology
  • Encourages more socio-economic activities and balanced urban development in nearby station areas
  • Provides better connectivity via a north-south backbone for the Greater Capital Region

Designing the MMSP: Options Considered

ROUTE OPTIONS

Three route alternatives for Metro Manila Subway Project were studied in the planning stage:

  • Option 1: EDSA Route
  • Option 2: Greenhills Route
  • Option 3: Katipunan Route

Route options were evaluated based on the following criteria:

  • Estimated project cost
  • Flood risk
  • Demand forecast
  • Earthquake risk
  • Fare revenue
  • Required project area
  • Economic loss due to traffic jams
  • Estimated Project
  • Affected Persons
  • Connectivity with CentralBusiness Districts (CBDs)
  • Noise and vibration
  • Intermodal connectivity

After evaluation of the JICA Study Team and discussions among relevant organizations including DOTr, Department of Public Works and Highways (DPWH), Metro Manila Development Authority (MMDA), and Philippine Bases Conversion and Development Authority (BCDA), Option 3 was evaluated to achieve most of the objectives and was selected.

DEPOT LOCATION OPTIONS

Two candidate sites of the depot location, one in Mindanao Avenue in Valenzuela City, and one in General Luis in Caloocan City, were studied in the planning stage. Mindanao Avenue was selected based on discussions among the relevant organizations in the same manner as the route alternatives.

The following criteria were used in the selection of depot location:

  • Construction cost
  • Existing and planned land use
  • Number of affected structures
  • Flood risk
  • Land acquisition area and cost

OPTIONS FOR CONSTRUCTION METHOD

For the underground structure, two methods of construction were compared: (1) cut & cover methods, in which excavation starts on the ground level and forms spaces from there down, and (2) the non-cut & cover methods, which includes the shield tunneling method and the New Australian Tunneling Method (NATM), both of which involve an excavation machine that goes through the earth to form spaces.

For stations, the cut and cover method was selected based on cost, construction period, and social and environmental considerations. For the excavation method between stations or along the project line, the non-cut & cover tunneling method, specifically the “shielded tunneling method”, is recommended, based on the same evaluation criteria used for the construction at the station sections.

Excavation method will be finalized in the Detailed Engineering Design Phase based on the results of geotechnical survey.

OPTIONS FOR TUNNEL STRUCTURES

For the tunnel structures, Double Tube Single Track (DTST) and Single Tube Double Track (STDT) were compared in the tunnel structure plan with respect to construction cost, construction period, occupying width of platform and ventilation requirements. DTST was found more favorable to a shielded tunnel in the line.

Assessing and Minimizing Impacts

WHAT ARE ENVIRONMENTAL IMPACTS?

The environmental impacts of the Metro Manila Subway Project were studied for the different phases of the project:

  • Pre-construction Impacts, which refers to changes to the existing environment resulting from clearing of construction sites and land acquisition
  • Construction Impacts, which refer to shortterm potential impacts directly during construction
  • Operational Impacts, which describe longterm effects from the operation and maintenance of the subway.

The project will avoid or find ways of lessening permanent impacts wherever possible, and plans will be made to minimize the disruption caused by temporary impacts.

A summary of the major environmental impacts is provided in the following table.

Activities that may cause impactsPotential Impacts

Engaging Stakeholders in Public Dialogue

A core part of the Metro Manila Subway Project environmental impact assessment is the consultation with the people who will be directly and indirectly affected by the project during construction and operation, such as people who will use the subway, live or own businesses/structures near the alignment. Relevant government agencies such as DENR, DPWH, MMDA, BCDA, PHIVOLCS, Presidential Commission for the Urban Poor, specific barangays and local government departments were involved in the consultation meetings.

Stakeholders’ consultation meetings and public scoping were conducted for the six (6) cities along the Metro Manila Subway Project alignment from March to August 2017. The public consultation has allowed the proponent to give the community a better understanding of the planning of the Project and site-specific factors and constraints that have to be taken into account of in selecting the preferred alignment and design of the Project.

Commitments to Mitigate Negative Impacts

As part of the Environmental Impact Assessment Process, DOTr and the JICA Study Team worked closely together with key stakeholders to address issues and develop workable solutions.

DOTr shall submit the necessary requirements to obtain an Environmental Compliance Certificate (ECC) from the Environmental Management Bureau Central Office of the DENR. DOTr is committed to implement an Environmental Management and Monitoring Plan in order to mitigate the major environmental impacts of the project from preconstruction to operation stages.

DOTr shall also implement a Resettlement Action Plan in accordance to the law to ensure that affected households and establishments are provided a proper relocation area and/or justly compensated.
