99 -- PROCUREMENT OF CORE-LOC MODEL ARMOR UNITS POC Contract Specialist, Sandy Staggs, 601-634-3698 The USAE Waterways Experiment Station (WES) intends to award a contract to Tiger Sea Products Ltd under authority 10 U.S.C. 2304 (c)(1) for providing CORE-LOC model armor units needed for physical model investigations of rubble mound structures. CORE-LOC (in real work) is a concrete armor shape developed for use as armoring on breakwaters. In model fashion the armor units are used in reproducing model breakwaters. Tiger Sea Products is the developer of the model units. The contract period will be one year. Several sizes of CORE-LOC model units are required which range between 100G to 300G. In order to meet project requirements the CORE-LOC model units must be precision made under stringent tolerances where the linear dimensions vary by no more than plus or minus 1.5%, specific gravity varies by no more than plus or minus 1.5% and the unit weight varies by no more than plus or minus 2.5%. The units must be constructed from weather-resistant epoxy resins that are impermeable, UV resistance, and capable of withstanding temperature extremes between minus 30 degrees centigrade to plus 45 degrees centigrade. The total number of individual units required is approximately 5600 and the minimum number of units required at each size is 500. In the event no other sources are found, the U.S. Government intends to award a contract to Tiger Sea Products Ltd. Solicitation documents are not available. Any inquires should be received within 15 days from the date of publication of this notice. See numbered Note 22. (0156)
