This estimate was made by applying the "Hanford Cost Estimating Formula" to the Oak Ridge GDP. This method applies a labor-cost formula to the cubic feet of waste in the Oak Ridge GDP facilities for three scenarios: protective (safe)

The gaseous decontamination process will remove at least 90 percent of residual uranium in the process equipment, reducing-the content to below the special nuclear materials security control limit.

The postulated LADE, which is intended to handle equipment and materials contaminated with uranium enriched to less than 20 percent 23su, contains 1,241,600 gross square feet of floor space, comparable in size to the K-27 or K-31 gaseous diffusion buildings. Each facility contains equipment for decontamination and s~ze-reduction of GDP components and waste materials and equipment for assaying packaged wastes to ensure that the residual uranium content of the packages meets disposal site acceptance criteria for uranium contamination before shipment.

For estimates May through August, the indirect rate is equal to 50 percent, a value equal to a 30 percent add-on for field indirects, a 3.3 percent add-on for home office overhead (3.3 percent of both direct and field indirects) , and a contractor's profit of 12 percent (12 percent of direct and indirect costs and overhead)

Direct costs, not including direct program integration costs, increased as a percent of total costs from 34 to 41 percent from the May estimate to the September estimate. Indirect costs plus program integration costs as a percent of total costs declined from 36 percent to 33 percent from the first to last estimate.

To compare the estimates, indirect costs and rollups are assumed to be included in the MMES labor cost and waste disposal formulas. Second, $2.751 billion of remedial action activities have been included in the MMES greenfield cost estimate.

. constructing and operating LADFs at Paducah and Portsmouth, which increases costs by 17.2 percent; refurbishing buildings undergoing D&D, which increases costs by 3.3 percent; constructing new administration buildings at Paducah and Portsmouth instead of refurbishing existing buildings, which increases costs by 0.3 percent; incorporating electrorefining capabilities at Oak Ridge, which decreases costs by 1.8 percent; providing HADFs at Oak Ridge and Portsmouth and LADFs at all sites, which increases costs by 21.6 percent; transporting Portsmouth X-326 equipment (processed highly enriched uranium)

Levels of confidence were calculated from the resulting cost estimates. Using this approach, under these probability distributions, TEG determined that there was a 50 percent chance that the cost of the project would be below $16.2 billion and a 100 percent chance that the cost would be below $28.7 billion (in 1992 dollars)

The Ebasco cost estimate also includes the cost in each period by determining the work hours, necessary materials and equipment, and associated indirect costs for each activity. The calculation of labor, materials, and equipment costs is a straightforward multiplication of costs per unit multiplied by the number of units.

From page 278... ...
. It is noted that this was not done for Program Integration, as indirect costs/workhours were considered in the original estimate basis and therefore no additional mark-up was necessary.

From page 279... ...
Other associated costs include indirect costs, home office overhead costs, and profit, amounting to a total of 43.17 percent, which were added to the direct cost. Under the category of Program Integration in the Ebasco cost estimate, a certain amount of personnel time was also allocated to waste management activities.
