Upon completion of the utility adjustment, the utility owner will submit a final billing of actual cost to the LPA. Final billings should reflect determination of eligibility of each item of cost for TxDOT reimbursement.

Final billings should include supporting documentation and a thoroughly detailed breakdown of costs. Supporting documentation includes time sheets, invoices, equipment usage reports, bid tabulations, Buy America compliance documentation, and payroll documentation. TxDOT must be furnished with sufficient information to ensure that payment will be eligible for Federal and/or TxDOT participation.

In addition to requirements for final billing details stated in the subsection 3, the final billing should also show applicable percentages (when used) so computed amounts may be verified.
