Vega Corporation of Tennessee - Contract No. 14626

As part of our annual audit plan, we audited costs billed to the Tennessee Valley Authority (TVA) by Vega Corporation of Tennessee for general construction and modification services performed under Contract No. 14626. Our audit included approximately $8.76 million in costs billed to TVA from contract inception, November 11, 2019, through April 30, 2021. Our objective was to determine if Vega billed TVA in accordance with the contract's terms. In summary, we determined (1) Vega overbilled TVA $4,070 in ineligible fee, and (2) TVA paid an additional $187,786 in labor costs because Vega used statutory payroll tax rates instead of effective payroll tax rates in the buildup of its craft labor billing rates. We also noted opportunities to improve contract administration by TVA. Specifically, we found the contract contained (1) language requiring subcontractor approval that does not match TVA's intent and (2) inconsistent language regarding markups on subcontractor costs.(Summary Only)
