25 CFR 170.473 - What happens when a construction project ends?
(a) At the end of a construction project, the agency or organization responsible for the project must make a final inspection. The inspection determines whether the project has been completed in reasonable conformity with the PS&E.
(1) Appropriate officials from the tribe, BIA, and FHWA should participate in the inspection, as well as contractors and maintenance personnel.
(2) All project information must be made available during final inspection and used to develop the IRR construction project closeout report. Some examples of project information are: Daily diaries, weekly progress reports, subcontracts, subcontract expenditures, salaries, equipment expenditures, as-built drawings, etc.
(b) An IRR construction project closeout is the final accounting of all IRR construction project expenditures. It is the closing of the financial books of the Federal Government for that construction project. Closeout occurs after:
(1) The final project inspection concludes; and
(2) The facility owner makes final acceptance of the project.
