Earthwork [SIG]

The earthwork objects calculate excavation and backfill volumes for foundation construction. These companion tools automatically derive geometry from a selected footing and compute quantities based on ground surface elevation.

OpenBrIM provides two earthwork quantity objects:

• Structure Excavation: Calculates the volume of earth to be removed from the original ground surface to the footing bottom

• Structure Backfill: Calculates the net volume of fill material needed after construction, automatically subtracting structural component volumes

Both objects work with any foundation type (Custom or Rectangular) and support both manual elevation input and DTM-based ground surfaces.
