MDBI enters Railway Infrastructure with MMSP Bulk Supply Substation (BSS) Groundbreaking

On May 5, 2025, MDBI Construction Corp. participated in the groundbreaking ceremony for the Bulk Supply Substation (BSS) of the Metro Manila Subway Project (MMSP) held in Valenzuela City.
The milestone event was attended by key officials from the Department of Transportation (DOTr), led by Secretary Vince Dizon, Valenzuela City Mayor Wes Gatchalian, representatives from the Japan International Cooperation Agency (JICA), MMSP Project Manager Oriental Consultants Global, and officials from the Japanese and French embassies.

The BSS will connect to the Meralco grid and step down electricity to power the East Valenzuela Depot, various subway stations, and the full MMSP railway network. MDBI is collaborating closely with Colas Rail—sister company of Bouygues Bâtiment International (BBI) and the design and construction lead for the BSS—alongside Colas’ partners Egis and Hitachi. Mitsubishi Corporation serves as the overall General Contractor for the project.

MDBI’s involvement marks the MDC Group’s entry into the railway infrastructure sector and underscores the company’s continued commitment to nation-building through the advancement of modern, sustainable transportation networks in Metro Manila.
