66 -- SCANNING LASER VIBRATION MEASUREMENT SYSTEM SOL RP99-035 DUE 080499 POC Brenda Goodwin, 304/285-5882; Contracting Officer, Rex S. Wolfe, Jr., 304/285-5883 THIS IS A COMBINED SYNOPSIS/SOLICITATION FOR COMMERCIAL ITEMS PREPARED IN ACCORDANCE WITH THE FORMAT IN SUBPART 12.6, AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. THIS ANNOUNCEMENT CONSTITUTES THE ONLY SOLICITATION; BIDS ARE BEING REQUESTED AND A WRITTEN SOLICITATION WILL NOT BE ISSUED. This solicitation is issued as Request for Proposal No. RP99-035. This procurement is being issued unrestricted. The Standard Industrial Classification is 3829 with a size standard of 500 employees. This solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 97-11. The National Institute for Occupational Safety and Health (NIOSH), Morgantown, WV, has a requirement for one (1) each of a state-of-the-art laser scan vibration measurement system with components/accessories to meet the specifications below. Offers should also include a 12-month hardware warranty, 6-month software maintenance and hardware storage boxes. The Government would also like to purchase a one-year extended warranty on the hardware with re-calibration of the system on the second anniversary of the delivery. The NIOSH project "Vibration and Noise Assessment of Powered Hand Tools" will investigate hand-powered tools used within various industries to determine: (a) their dynamic, worker-related characteristics (vibration, impulse, and noise signatures), (b) the extent to which they are transmitted to the worker, (c) the transient effects they have on the worker, and (d) the engineering control-related means of mitigating same. The concurrent and subsequent transient impact of physical signatures, which are transmitted to the hand, arm, shoulder, and heads of a carefully selected sample of workers, will be investigated via the use of the state-of-the-art vibration measurement system and physiological measures (e.g. EMG, cardiopulmonary), postural measures (upper-extremity joint angles), subjective measures of discomfort, and sensoriperceptual measures (hearing-, vision-, & tactile-related). Engineering controls will be proposed and evaluated to mitigate such effects. Biomechanical models will be developed to reflect the knowledge gained. One of the major features is the measurement range of velocity. The measurement velocity of the laser vibrometer produced by many instument manufactures can only be up to plus or minus 1m/s, which is not sufficient to the hand-transmitted vibration studies in some cases. For example, the acceleration on a chipping hammer reported by NIOSH was more than 1,000 m/s2 at 31.5Hz. This means that the vibration velocity could be more than 5 m/s. Such a limitation has also been confirmed from several researchers who have used the laser vibrometers with the maximum velocity of 1m/s for hand-arm vibration studies. Offerors shall comply with the following SPECIFICATIONS for a SCANNING LASER DOPLER VIBROMETER: I. Measurement range of velocity must be up to plus or minus 10m/s; II. Must be able to measure vibrations accurately with frequencies of 5 kHz or higher; III. Any software in the system should be user-friendly; IV. Full-field, live and zoomable (up to 24 x digital zoom) video should be used for defining the precise location of scan points/areas. Scan measurement point grids must be able to be superimposed on live video image. Laser must be visible and can be moved using mouse over stationary video image; V. Scan points/areas must be able to be defined conveniently and accurately. Scans should be able to comprise multiple objects each with it's own grid density (up to 512 x 512 scan points per object) and coordinate system (cartesian, polar and hexagonal). Features should include object rotation, grid translation, object grouping, individually located scan points and saving/loading of scan geometry files; VI. Signal enhancement and data quality check must be applied to every scan point. It should include dithered laser "searching" for best signal-to-noise ratio data at every scan point. Non-optimal data should be rejected. Color coded dot should be used to indicate status of measurement for every point scanned. Status record should be saved with scan data. It should be able to automatically re-measure the non-optimal points; VII. Must be able to use a combination of FFT analysis and selectable bandpass filtering for scan speeds up to 150 points per second. Measurements should only be taken while the laser scanners are stationary in order to minimize laser speckle noise. The system must be able to display normalized FRFs from FastScan data. Signal enhancement should be employed during the system scans; VIII. Must be able to scan 40 degree x 40 degree field; IX. Must be able to conduct fast FFT scan speed (up to about 12 -- 15 points per second); X. The system should allow customers to optimize optical sensitivity, noise floor and vibration velocity range to the application; XI. Must be able to conduct 3-D animations incorporating animated video image; XII. Noise floor must be less than 0.1 m/s per root Hz; XIII. 1% calibration accuracy is required; XIV. Must have on/off switchable tracking filters; XV. Must have on/off switchable cosine correction for laser scan angle; XVI. Must have comprehensive on-line help; XVII. Available time domain data must be saved at all pre-defined scan points; XVIII. Training and technique support must be available; and XIX. Must be Y2K compliant. XX. The Government desires delivery within 90 days after receipt of contract. XXI. Offers shall propose based on a delivered price, F.O.B. Destination (Morgantown, West Virginia) and the requirements at FAR 52.214.21 "Descriptive Literature" apply. Information provided must demonstrate the unit's ability to meet the stated Technical Criteria (specification) or your offer may be rejected. The Government anticipates one award for the entire system to the responsive, responsible offeror whose proposal is considered most advantageous to the Government. The following FAR provisions apply to this solicitation: FAR 52.212-1, Instructions to Offerors -- Commercial Items; 52.212-4, Contract Terms and Conditions -- Commercial Items and 52.212-5 Contract Terms and Conditions Required to Implement Statutes or Executive Orders -- Commercial Items.
