OnGrade Management System Software
The OnGrade Management System (OGMS) plotting software is configured to work with the information
taken at the start and end of a gravity sewer bore, and with the information obtained from the grade pole
during the bore. The software can be used during the bore by connecting a laptop computer to the output
port on the drilling unit display. The data can also be logged onto the SD card in the display and then
downloaded 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 a
bore planning tool. It assumes the route for the gravity sewer line will be a direct shot and has been laid out
by a planning engineer or designer ahead of time. It also takes into account the special information
provided 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 installed
pipe can be printed to provide an as-built record for the job.
Inspection Tools
Beacon Trolley
1. Install sideload isolator onto the clocking end of the beacon (away from the battery cap) used for the
bore.
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. See tracker manual.
