View Detailed Machine Data by Cell

Use the Detailed Cell Viewer command to review machine data cell-by-cell by picking locations in a machine data overlay. The heat map in the overlay is a high-resolution image that you can zoom in to when you pick a cell. Each cell is a 0.34 m square of coverage.

Licensed module; See the Subscription Plans page. For a license matrix by command, see the License page in the TBC Community. Also see View and manage licensed features.
Machine data overlay in the Plan View

To access the command:

Select Detailed Cell Viewer in Construction Data > Machine Data.

To view compaction data per cell:

From the Pick a cell location box, pick a cell in the overlay (location where there is machine data) in the Plan View.
In the Lifts list, check the box next to each design surface for which you want review data in the selected cell.
The Detailed Cell Viewer table populates with data from the selected cell.
Review the values and export them to a Microsoft^® Excel spreadsheet if desired.

Options:

Export to Excel - Click this to output the displayed cell data to Microsoft^® Excel.


Reported values
Design name	Shows the name of the selected design for the row of data.
Lift ID	Shows the unique name of the lift in the material layer.
Pass number	Shows the number of the pass for the row of data.
Target pass count	Shows the ideal number of passes as specified for the selected lift.
Time	Shows the date and time the compactor passed over the cell (for this pass number).
Machine name	Shows the identified of the compactor (or other machine).
Elevation	Shows the elevation of the top of the lift after the specified pass.
Machine speed	Shows the ground velocity of the compactor (or other machine) as it passed over the cell.
Machine direction	Shows whether the compactor (or other machine) was moving forward or backward.
Material temperature	For asphalt compactors, this shows the temperature of the material as it is being laid.
CMV	Shows the relative stiffness of the compacted material.
Target CMV	Shows the ideal CMV as specified for this lift in the Material and Site Improvement Manager.
MDP	Shows the machine drive power/rolling resistance of the machine over the cell, as a measure of compaction.
Thickness	Shows the vertical //height of the lift as measured between the previous lift's elevation and the current elevation.
Target thickness	Shows the ideal thickness as specified for this lift in the site improvement's material layer.
Vibe on	Shows whether drum vibration was on or off when the compactor passed over the cell.
Amplitude	If vibe state was on, this shows the maximum extent of the drum vibration (impact force).
Frequency	Shows the reported vibratory drum frequency (impacts/minute) on a compactor in Hz.
GPS accuracy	Shows one of these levels: GPS - Provides quick medium/submeter horizontal accuracy deployment, which can be used with satellite-based augmentation system (SBAS) such as WAAS. GPS Real-time Kinematic (RTK) - Provides higher accuracy, centimeter-level horizontal positioning and vertical guidance, which are critical levels of accuracy for compaction to a 3D design model and monitoring on-grade accuracy post compaction. Universal Total Station (UTS) - Can provide millimeter-level horizontal and vertical accuracies. Use of this system is required when compacting expensive imported material layers and lifts to very tight tolerances. This technology can be used where GNSS satellites are obstructed or not available (e.g., areas of heavy foliage, inside buildings and tunnels, and urban cityscapes).
GPS mode	The reported GPSMode values from a machine.
GPS tolerance	The GPS tolerance, or error limit, of GPS positions being used. This is a value in the range of 0 to 4095 millimeters.
Guidance mode	Guidance Mode relates to the GPS guidance mode in use on the machine control system at the time the cell pass was measured. These are values such as RTK, Autonomous, SBAS, Differential etc.
RMV	Shows the resonance meter (drum bounce) value indicating how close the reactive force of the ground against the compactive energy being directed into it by the offset-mass vibrating drum is to causing the drum to bounce.
Decoupled RMV	Decoupled RMV is the Resonance Meter Value at which the drum of a vibratory compactor is ‘decoupled’ with the ground. In other words, it’s bouncing when RMV values are above this threshold value.
Radio Latency	Radio latency reported by the machine systems, where the latency refers to the age of the RTK corrections induced by the radio network transmission latency between the RTK base station and the machine.
