25 CFR 170.471 - How are projects administered?
(a) When a tribe carries out an IRR project under ISDEAA, BIA will monitor performance under the requirements of 25 CFR 900.130 and 900.131(b)(9) or 25 CFR 1000.243 and 1000.249(c) and (e), as appropriate. If BIA discovers a problem during an on-site monitoring visit, BIA must promptly notify the tribe and, if asked, provide technical assistance.
(b) BIA or the tribal government, as provided for under the contract or agreement, is responsible for day-to-day project inspections except for BIA monitoring under paragraph (a) of this section.
(c) BIA must process substantial changes in the scope of a construction project in coordination with the affected tribe.
(d) The tribe, other contractors, and BIA may perform quality control.
(e) Only the licensed professional engineer may change an IRR project's plans, specifications, and estimates (PS&E) during construction.
(1) For substantial changes, the original approving agency must review the change. The approving agency is the Federal, tribal, State, or local entity with PS&E approval authority over the project.
(2) In making any substantial change, the approving agency must consult with the affected tribe and the entity having maintenance responsibility.
(3) A change that exceeds the limits of available funding may be made only with the approving agency's consent.
