This legislation, known as the "Keep America Building Act," is designed to provide for the continuity of certain federal contracts during periods of government shutdown. It explicitly states that no Federal funds may be used to suspend, delay, or interrupt all or part of the work on a project under contract during any lapse in appropriations. The bill's core purpose is to prevent the cessation or disruption of work agreed to in federal contracts due to funding gaps. This measure seeks to ensure that ongoing projects can continue without interruption, thereby mitigating the negative impacts of appropriations lapses on federal operations and contractors.
