The Build! Build! Build! Infrastructure Program (BBB) was the infrastructure program of the administration of Rodrigo Duterte, the 16th president of the Philippines. A key component of his socioeconomic policy, the program aimed to reduce poverty, encourage economic growth and reduce congestion in Metro Manila, and address the country's infrastructure gap. Launched on April 18, 2017 and mainly implemented by the Department of Public Works and Highways (DPWH) under Secretary Mark Villar, the program also included the continuation of 44 infrastructure projects under previous administrations. By November 2021, DPWH Undersecretary Emil K. Sadain was appointed by Duterte as the program's "chief implementer" after Villar's resignation from the agency.
