Guam Department of Public Works

The Guam Department of Public Works, often abbreviated to DPW, is an agency of the government of Guam that manages public works and transportation in Guam. It receives some of its funding from the U.S. federal government, including the Federal Highway Administration, Office of Insular Affairs, and Department of Defense. In 2025, its budget was USD $157.7 million, with $135.7 million (86.1%) of the money coming from the federal government.

The department handles the construction and maintenance of highways, and bridges, and government buildings, including public schools. It runs bus services for students and the public, and is responsible for manufacturing and maintaining vehicles needed for its services, including busses and construction vehicles. Additional DPW responsibilities include building inspection, issuance of citations for noncompliant buildings, cleanup of trash and junk vehicles along highways and waterways, road safety infrastructure (such as traffic delineators), and flood prevention. It regularly collaborates with other Guamanian government agencies, such as the Guam Environmental Protection Agency.

As of fiscal year 2023, the department has 231 employees. The director, Vincent P. Arriola, was nominated to the position by Governor Lourdes A. Leon Guerrero and Lieutenant Governor Josh Tenorio, and took office in 2019. There are also two deputy directors, Linda J. Ibanez and Ernest G. Candoleta, Jr.
