66 -- GROUND PENETRATING RADAR TO DETECT SUBSURFACE VOIDS SOL N47408-99-R-8889 DUE 100899 POC Dr. Javier Malvar, PhD, 805-982-1447, fax 982-1074, email: malvarlj@nfesc.navy.mil GROUND PENETRATING RADAR FOR DETECTION OF SUBSURFACE VOIDS. POC Javier Malvar, NFESC Code 63, (805) 982-1447, Fax (805) 982-1074, or Greg Cline (805) 982-3655. The Government is seeking technical information and sources that may or may not lead to procurement of ground penetrating radar (GPR) or alternate technology for Navy airfield pavements. Relevant GPR (or alternate) technology should be able to detect subsurface voids below 12-inch thick concrete or asphalt pavements. These subsurface voids can be due to either natural sinkholes of erosion from leaking pipes, and can occur at depths up to 20 feet. Interested parties must provide sufficient technical literature for in-house evaluation of the proposed technology capabilities. Closing date is 8 October 1999. All information material shall be forwarded at no cost to the Government. This notice is not a request for proposals and no contract will be awarded solely on the basis of the responses hereto, or any follow-up information subsequently solicited. POC: L.
