F -- EVALUATION OF COATING AND SURFACE REMOVAL TECHNOLOGIES FOR CONCRETE AND BRICK WALLS AND CONCRETE CEILINGS - AN ENGINEERING STUDY SOL HCET009. DUE 122096. POC Dr. M.A. Ebadian, (305) 348-3585, Leo Lagos (305) 348-1810. The Department of Energy at the Fernald and Mound Plant in Ohio, and the Hemispheric Center for Environmental Technology (HCET) at Florida International University (FIU) are seeking qualified suppliers to conduct an engineering study for the comparative analysis of surface removal decontamination technologies for concrete walls, brick walls, and concrete ceilings. The study is being performed to support the U.S. Department of Energy's environmental restoration efforts. The study will be conducted at the campus of FIU in Miami, Florida. Each technology will be tested for surface removal from coated concrete walls, brick walls, and concrete ceilings; in addition, the technologies will be tested for aggressive concrete removal (1/4 to 1.0 inch) from noncoated concrete walls. The operating time must provide sufficient time to collect the operational and safety information required to evaluate each technology. Additional data will be collected on the capital costs, maintenance costs, and equipment staging/destaging costs. The following surrogates will be provided for the surface removal tests: a 10 ft. high by 20 ft. long coated concrete wall; a 10 ft. high by 20 ft. long coated brick wall; a 10 ft. wide by 20 ft. long coated concrete ceiling. These surfaces will be coated with an aliphatic urethane epoxy coating. The following surrogate will be provided for the aggressive concrete removal (1/4 to 1.0 inch) test; a 10 ft. high by 20 ft. long noncoated concrete wall. The surrogates will not be radiologically contaminated. Some examples of technologies to be included in the study are: ultra high pressure water (greater than or equal to 15,000 psi), milling, scabbling, centrifugal shot blasting, and impregnated soft media blasting; other technologies are also encouraged to respond. Qualified suppliers will be asked to optimize the technology as it is applied to each surrogate. Qualified firms shall have five years minimum experience in surface removal and two years minimum operations experience with the proposed technology. The qualified firms are to provide references of surface removal jobs completed. Qualified firms shall also state the maximum depth of concrete removal achieved in a single application. Interested firms should send a Letter of Qualification stating how the firm meets the minimum requirements, including address, contact, and telephone and fax numbers to Mr. Leonel E. Lagos, Hemispheric Center for Environmental Technology at Florida International University, Engineering and Applied Science, Suite 2100, Miami, Florida 33199, no later than 12/20/96. The letters of qualification will be used to prequalify firms. The Request for Proposal (RFP) will be available to the qualified firms by December 30, 1996. (330)
