OnGrade Operator’s Manual Systems and Equipment - 45OnGrade Management System SoftwareOnGrade Management System SoftwareThe OnGrade Management System (OGMS) plotting software is configured to work with the informationtaken at the start and end of a gravity sewer bore, and with the information obtained from the grade poleduring the bore. The software can be used during the bore by connecting a laptop computer to the outputport on the drilling unit display. The data can also be logged onto the SD card in the display and thendownloaded and plotted using OGMS after the bore is completed. Data can also be entered manually.Although OGMS bears some similarity to the Trac Management System (TMS) software, OGMS is not abore planning tool. It assumes the route for the gravity sewer line will be a direct shot and has been laid outby a planning engineer or designer ahead of time. It also takes into account the special informationprovided by the grade pole and the beacon trolley to plot the features on the graph.OGMS software can plot the bore as it progresses and also plot the installed pipe. The plot of the installedpipe can be printed to provide an as-built record for the job.Inspection ToolsBeacon Trolley1. Install sideload isolator onto the clocking end of the beacon (away from the battery cap) used for thebore.2. Place beacon into beacon trough on grade trolley with battery cap toward the back end of the trolley(away from the camera).3. Ensure beacon is seated all the way down in the trough.4. Rotate the trolley on its axis a couple of times to ensure the beacon is awake.5. Seat trolley in the V-groove on the beacon calibration fixture.6. Place Smart Tool level across the edges of the roller on one side of the beacon trolley.7. Adjust rollers until the Smart Level indicates the trolley is level.8. Calibrate 8500TK pitch.
