USACE, Engineer Research and Development Center (ERDC) Contracting Office intends to issue a sole source award to Oyo-Geospace Technologies,7007 Pinemont Dr., Houston TX 77040 . Four 4-channel sensors are being procured in conjunction with four 4-channel autonomous data recorders for making underwater acoustic and seismic measurements. less than br greater than less than br greater than Specifications for 3-axis Geophone and Hydrophone with Data Acquisition System less than br greater than less than br greater than The instruments will be used in conjunction with a fiber optic sensing system (FOSS). The FOSS is being used in testing to determine the utility of these systems for seismic and acoustic monitoring in shallow water - littoral environments. Data collected with the geophone/hydrophone sensor system will be compared with that collected with the FOSS for validation/verification purposes. less than br greater than less than br greater than The 4-channel geophone/hydrophone system will be fully gimbaled with three mutually perpendicular geophone axes. The package will be fluid-filled with precision o-rings and full water blocked wires so that it can be used to depths of 2,000 meters. It shall be less than 18 inches long and weigh less than 12 lbs. Each 4-channel unit will have 100 m of 4 pair waterblock cable with connectors compatible with data logger. less than br greater than less than br greater than The geophone sensors will have a 10 Hz resonance frequency and a sensitivity of 0.500 less than br greater than V/(in./s) at 70% damping. They shall have a clean band pass of 250 Hz or greater. The hydrophone will also have a 10 Hz resonance frequency and an operating depth of 1 to 250 ft. less than br greater than The voltage sensitivity will be 11.2 V/bar. less than br greater than less than br greater than Each data logger will be able to log data from four channels with 24-bit resolution and 4 Gbytes of storage per channel. The operating temperature will be at least -40_ C to 85_ C. It will have the capability to record data at rates from 250 to 4000 Samples per second. The internal clock will be synchronized via GPS and will be accurate to within 1 sec of UTC. It will operate on a less than br greater than 12 Volt battery. It will have adjustable gain from 0 dB to 36 dB with total harmonic distortion of no more than 0.0005%. It will have an anti-aliasing filter with rejection at Nyquist of 130 dB or better. It will weigh no more than 2 lbs. less than br greater than less than br greater than The system will include a ruggedized laptop computer with software to control the data loggers and to read the data into files using SEG-2 or SEG-D type formats. The software will also allow for data to be read to a field database and/or hard media, such as a hard disk. less than br greater than less than br greater than Oyo-Geospace Technologies is the only manufacturer identified to meet these stringent specifications. less than br greater than less than br greater than The Government intends to procure from only one source under the authority of FAR 13.106-1(b). This will be a commercial acquisition using simplified acquisition procedures per FAR 13. This is not a request for competitive proposals and no solicitation is available. All responsible sources may submit a capability statement, proposal, or quotation to the Contract Specialist by 11:00 AM CST, Monday November 26, 2012. Interested parties may submit information for consideration by the government to:
