hand-held grinder comparison
This cost analysis compares the Flex hand-held grinder improved technology for removing concrete walls surfaces to two different baseline technologies. Costs for the improved technology are based on one decontamination technician using the grinder inside a radiation zone assisted by one decontamination technician working outside the rad-zone. Other costs included for the innovative technology are mobilizing and setting up the equipment necessary to run the grinder, RCT monitoring for radiological contamination, breaking down and demobilizing equipment at the completion of the work, and disposal of waste generated from the grinding operation.
Costs for the baseline technologies are based upon the same number of D&D workers used for the improved technology conducting the same basic removal activities, but using the two different hand-held tools. As with the innovative technology, other costs for the baseline technologies include mobilization and demobilization of equipment, RCT monitoring, and waste disposal.
The selected basic activities analyzed come from the Hazardous, Toxic, Radioactive Waste Remedial Action Work Breakdown Structure and Data Dictionary (HTRW RA WBS), USACE, 1996. The HTRW RA WBS, developed by an interagency group, used in this analysis to provide consistency with the established national standards.
Some costs are omitted from this analysis so that it is easier to understand and to facilitate comparison with costs for the individual site. The overhead and general and administrative (G&A) mark up costs for the site contractor managing the demonstration are omitted from this analysis. Overhead and G&A rates for each DOE site vary in magnitude and in the way they are applied. Decision makers seeking site specific costs can apply their site’s rates to this analysis without having to first back-out the rates used at the Hanford Site.
