Contract for Staff Augmentation Services

We audited $58.5million of costs billed to TVA by a contractor for staff augmentation support services during FYs 2005 and 2006. We determined TVA was overbilled about $540,000 for labor costs due to duplicate billings, overpayments of labor hours, and use of incorrect wage rates. We also found the contractor had not maintained documentation to support approximately $340,000 of travel expenses billed to TVA. The contractor and TVA management agreed with our findings, and TVA management is planning to (1)recover the overbilled amount and (2)implement a requirement for the contractor to maintain documentation of travel expenses that are billed to TVA.
