170.602—If a tribe incurs unforeseen construction costs, can it get additional funds?
Yes. To the extent feasible, the Secretary must pay for all costs incurred resulting from unforeseen circumstances of the construction process (i.e., cost overruns). If the Secretary is unable to fund the unforeseen costs in a cost reimbursable contract, the tribe may suspend performance of the contract until sufficient additional funds are awarded. (See 25 CFR 900.130(e).)
