Contract for Welding Services

We determined a contractor overbilled TVA $563,773 (out of $6.2 million that had been billed) for providing welding services for various nuclear projects. The overbilling included (1) labor costs due to the contractor's use of incorrect labor rates, misclassifications of personnel, and unsupported labor hours; (2) ineligible or unsupported mobilization, travel, and per diem costs; (3) direct billed overhead labor; and (4) duplicate costs. TVA agreed with most of our findings and is working with the contractor to resolve the overbillings. Summary Only
