PROCUREMENT PROCESS
USACE awarded the contract to perform the soil remediation at OU-3 to Remedial Services

Services International. Remedial Services International was subsequently acquired by H&S
Consultants, which was later acquired by ABC Corporation. The contract was awarded using a
firm fixed-price cost structure. On September 23, 1996, the contract was converted to a cost plus
fixed fee contract.

Costs are based on the respective years that the costs were incurred. The ROD estimates were adjusted from
1988 dollars to the appropriate year's dollar basis using ENR building cost index factors.

Differences between the actual RA operating costs and the adjusted ROD estimate are largely attributable to the
waiting phase associated with a project shutdown pending the outcome of a lawsuit filed by a citizens group
(,268,000). Costs were saved during site restoration by using clean, excavated rock as backfill and by
eliminating the need for vegetative cover (see Section 9 for additional information).
