Contractors’ Use of Equipment Provided by TVA’s Equipment Support Services

As part of our annual audit plan, we performed an audit to determine the effectiveness of the Tennessee Valley Authority’s (TVA) process for managing heavy equipment provided to contractors through TVA’s Equipment Support Services (ESS) group. ESS provides heavy equipment and other equipment support services to business units across TVA and charges specific projects for the equipment which is provided. ESS’s customers include (1) TVA organizations obtaining services directly or (2) contractors performing work for the TVA organizations. In summary, we determined TVA was not effectively managing contractors’ use of equipment provided by ESS. Specifically, we found:• ESS provides equipment to contractors on TVA projects that have cost reimbursable payment terms. Although ESS does not bill the contractors for the equipment (i.e., ESS charges a TVA project, not the contractor), certain contractors bill TVA for the ESS equipment even though their contract with TVA provides that TVA can only be billed for actual equipment costs. Even though the contractors subsequently provide credits or refunds to TVA for the equipment, it is administratively difficult for TVA to ensure it receives reimbursement for all the costs billed by the contractor.• ESS provides equipment to certain contractors on TVA projects that have fixed price or fixed unit rate payment terms. However, TVA’s Standard Programs and Processes (SPP) do not provide guidelines or processes for TVA to determine the cost effectiveness of providing ESS equipment on fixed price/fixed unit rate projects or to ensure TVA receives the appropriate reductions on the fixed price/fixed unit rates.
