66 -- DRILL PARAMETER RECORDER SOL 99D88340002 DUE 120798 POC D7810@do.usbr.gov WEB: AAMS Current Solicitation Listing, http://www.usbr.gov/aamsden/. E-MAIL: Bureau of Reclamation, D7810@do.usbr.gov. Requirements for a Drill Parameter Recorder: 1. This unit must be designed specifically for monitoring rotary drilling operations for geotechnical site investigations. The Unit must be fully capable of recording boring and core drilling parameters and instantaneously logging those parameters. A. Depth (1200 FT) B. Instant Advance Rate (0 TO 20 FPM) C. Rotational speed (0 TO 2400 RPM) D. Water or drilling fluid pressure (UP TO 750 PSI OR 50 BAR) E. Thrust and holdback (restraint pressure) F. Torque G. Instant drilling rate H. Time and duration I. Drill mast inclination J. Record grouting or pumping operations from 8 pumps K. Luegeon testing L. Must be able to record any tool drop while drilling. 2. The DPR unit will come equipped with software specifically designed to display rotary drilling data and to provide an interpretive log of that data. Interpretations will include formation hardness/ softness and rock porosity. The unit with it's software will be capable of providing a vibratory log of the drilling parameters as well as indicate formation changes. The unit will be capable of eliminating influence from drill rod additions and be capable of smoothing the recorded curves of activity. It will be able to search for de-compressed zones in the formation thru real time data interpretation and step integration. This interpretation capability must be able to accurately detect soft friable zones, water loss areas, vugs, harder formations and display an easily readable print out or read out. It will be capable of providing a statistical analysis table using stored data from previous holes, and the ability to re-edit data. It must possess a simple request program that is user friendly in operation. 3. The unit will have an upgradeable software package that will readily integrate with existing US.BOR. Equipment. A removable digital memory bloc unit that can be immediately downloaded to another PC utilizing EXEPF software is required. The unit will have a high definition printer producing a high quality plot of the hole data. The heading on the plot will feature, coordinates and parameter names and their scales in a readable fashion. It must have the capability to analyze the parameters real time and inform the operator of changes in boring conditions that fail to match the set instructions. It must be capable of detecting zones that require special boring techniques and halt operations and set the procedure to follow . 4. The unit will be impervious to weather, capable of working in extreme weather conditions hot or cold, uneffected by vibration from the drilling equipment, fluids or chemicals such as diesel fuel or lubricants.
