Proposed Hourly Labor and Drilling Services Unit Rates

At the request of the Tennessee Valley Authority's (TVA) Supply Chain, the OIG examined proposed hourly labor rates and drilling services unit rates for a managed task contract for TVA's Dam Safety Assurance Program. Our objective was to determine if the proposed hourly labor rates and drilling services unit rates were fairly stated. In our opinion, the proposed hourly labor rates were fairly stated. However, we found (1) the proposed drilling services unit rates included overstated labor markup rates, and (2) the hourly labor rates did not include a driller helper labor classification to be utilized for drilling services when additional helpers were needed. TVA's Supply Chain subsequently entered into a contract with the vendor and was successful in negotiating a (1) reduction in proposed drilling services unit rates which will potentially save TVA $46,300, based on TVA's plans to spend $40 million over 5 years, and (2) new labor category within drilling services for use when additional support is needed in the field. In addition, we compared the vendor's effective profit included in the proposed hourly labor rates to the profit rates included in a similar contract TVA has with the vendor and found the mix of field and home office labor will determine which contract would result in lower costs to TVA.(Summary Only)
