Compare Surfaces and Calculate Volumes

Compare Surfaces and Calculate Volumes

Surfaces in WorksOS are either created in other programs, such as Trimble Business Center (TBC), and imported as .ttm files or created when .tag files are processed when they automatically come into WorksOS.

Using your machine control system’s GNSS (GPS) data, WorksOS accurately maps the locations and elevations of every place your machines work. From that data, you can generate an as-built surface, which is the last pass of a machine creating the final surface of the day. Then, you can compare that last as-built surface to a previous as-built surface.

Based on the change/difference between the two surfaces, you can calculate the volumes. Anywhere the elevation went down is cut and anywhere it went up is fill, so you can also generate a cut/fill map.

  1. Navigate to the Map view.

  2. Click the Selected Filters icon.

  3. Expand the Date Range section, select Project Extents, and click Apply.

  4. Click the Metrics fly-out and choose Volume in the list.

  5. Choose to calculate based on the filter you selected or select Design/Surveyed Surface and choose the surface in the list.

  6. Click Calculate to run the calculations.

  7. In the Quality Metrics pane, review the Completed and Remaining volumes (deficit or surplus, total, area covered by machines, and material density percentages (if applied).
