A -- REPOSITONABLE PISTON-TYPE SPECTRAL WAVE GENERATORS SOL DACW39-97-R-0009 DUE 031897 POC Sandra Staggs, Contract Specialist, 601/634-3698 The USAE Waterways Experiment Station (WES) proposes to award a contract to MTS Systems Corporation, Eden Prairie, MN, under authority of 10 USC 2304(c)(1) for the fabrication, delivery and installation of 3 totally electric, unidirectional, repositionable, piston-type spectral wave generators with pertinent physical dimensions as follows: (a)wave board height, 4.667 length in feet, 1.42 length in meters, (b) wave board length without extenders, 15 feet in length, 4.57 length in meters, (c) wave board length with extenders, 25 feet in length, 7.62 length in meters, (d) upper height of frame, 5.83 feet in length, 1.78 length in meters, and (e) length from retracted wave board to rear of frame, 10.55 length in feet, and 3.22 length in meters. In addition the wave machines must be constructed so that all performance aspects are 100% compatible with the existing wave machine and software being used in the Longshore Sediment Transport Facility (LSTF). The wave machines must be constructed such that key components will have an estimated life of 3,000 hours continuous use. Acquisition of these additional wave generators is necessary to complete development of the LSTF. These additional generators will increase the wavefront from its present 100 feet to 175 feet, a criticial requirement for modeling coastal structures and their effect on navigation, sediment deposition, and erosion. Because the new wave machines must operate in concert with the existing wave machines, it is imperative that performance specifications, electronic control systems, and overall dimensions match the existing machines perfectly. The existing wave machines were purchased under contract from MTS in 1995. In the event no other sorces are found the Government intends to award a contract as stated above. Solicitation document are not available. Any inquiries should be within 15 days from date of publication of this notice. See numbered Note 22. (0062)
