Build Local, Hire Local Act This bill imposes various requirements on certain federally assisted infrastructure projects. The bill also creates infrastructure-related grant programs and establishes the Buy America Bureau. Such federally assisted infrastructure projects must (1) employ a certain percentage of local workers to the maximum extent practicable; and (2) prioritize hiring certain individuals, such as veterans and those facing barriers to employment. A certain percentage of funds for such projects shall be used for contracts with small businesses and certain targeted businesses, such as those owned by socially or economically disadvantaged individuals, women, or individuals with disabilities. When applying for a contract, grant, or loan related to such a project, the applying entity must disclose whether there are any rulings, such as a civil judgment, finding that the entity has violated certain federal labor and occupational safety laws in the last three years. In addition, the Department of Transportation must award grants to entities in disadvantaged and underserved communities for infrastructure projects that create connected, economically prosperous, and environmentally healthy communities. Further, the Department of Labor must provide grants to workforce development boards and industry partnerships for job training programs to train certain groups, such as individuals with barriers to employment, for jobs in targeted infrastructure industries. The bill also establishes the Buy America Bureau within the Department of Commerce to oversee project compliance with existing laws that require the use of U.S.-made materials in certain federally funded projects.
