Summary: The Air Force lacked a well-supported rationale for combining, under a single contract, the diverse workloads at the closing Sacramento air logistics center. This requirement may unduly restrict competition by eliminating potential bidders who are capable of performing some, but not all, of the individual workloads. GAO reviewed an Air Force report and found that it did not provide adequate information to support the determination that the workloads could not as logically and economically be performed without combination by potentially qualified sources. Subsequently, the Air Force provided additional supporting rationale for the workload combination. GAO reviewed the Air Force's rationale and found that it was not well supported. Although the Air Force's rationale is not at this point sufficient to justify the workload combination, the rationale for combination contains some elements, such as readiness concerns and potential competition enhancements, that, if supported, could establish the reasonableness of the combination under the acquisition laws.
