In which part of the Federal Acquisition Regulation (FAR) would you find rules regarding contract modifications?

FAR Part 43 is dedicated to the policies and procedures surrounding contract modifications. This includes guidance on when and how contracts can be modified, detailing the circumstances under which changes can be made, the types of changes that are permissible, and the processes to be followed for those modifications. Key aspects covered in this section include unilateral and bilateral modifications, changes in the scope of work, and administrative changes. Understanding this part is crucial for acquisition practitioners to ensure compliance with regulatory requirements when making necessary changes to contracts throughout their lifecycle.

The other parts mentioned do not focus specifically on contract modifications. For instance, FAR Part 41 pertains to acquisition of utility services, FAR Part 45 addresses the management of government property in the possession of contractors, and FAR Part 47 deals with transportation. None of these sections address the specifics of modifying contracts, making Part 43 the correct choice for understanding the rules and procedures related to contract modifications.
