Final answer:
The statement is generally true; operation and maintenance manuals are indeed part of contract close-out. They serve as crucial deliverables that allow the client to manage project outputs once the project team concludes its work.
Step-by-step explanation:
The statement that operation and maintenance manuals are part of contract close-out is generally True. The close-out phase of a project involves ensuring that all aspects of the project are completed satisfactorily, including the submission and acceptance of all necessary documentation. Operation and maintenance manuals are essential deliverables that provide the client with the information needed to operate, maintain, and troubleshoot the project outputs after the project team has disbanded.
Including these manuals as part of the contract close-out ensures that clients have all necessary resources to effectively make use of the project's deliverables, and that contractors have met their contractual obligations in providing comprehensive information on how to handle the completed product, system, or structure in the long term.
