Morsey Constructors, LLC - Contract No. 9275

As part of our annual audit plan, we audited costs billed to the Tennessee Valley Authority (TVA) by Morsey Constructors, LLC (Morsey) for general construction and modification services performed under Contract No. 9275. Our audit included approximately $8.3 million in costs billed to TVA during calendar years 2014 through 2018. Our objective was to determine if Morsey billed TVA in accordance with the contract's terms.In summary, we determined Morsey overbilled TVA up to $3,819,541, including (1) from $1,543,520 to $3,698,483 in subcontractor costs that had not been preapproved by TVA, <br> (2) $100,354 in overbilled equipment costs, (3) $36,945 in unsupported and ineligible travel costs, and (4) a net underbilling of $16,241 because Morsey billed incorrect craft and noncraft time and materials billing rates. In addition, we determined TVA paid an additional $134,810 in labor costs because Morsey used statutory payroll tax rates instead of effective payroll tax rates in the build up of its craft and noncraft labor billing rates.
