Cut and fill, from a PDF to a 3D surface.
SiteWorx/OS builds 3D models of the existing site and the proposed grade straight from the contours on your site plans. Calculate cut, fill, and sub-grade volumes, balance the site, and hand the results off to Excel, DWG, CSV, or PDF.
3D models of the existing and proposed site.
SiteWorx/OS digitizes existing-ground contours and proposed-grade design lines straight from the sheet and builds a 3D model of each. Drop in spot elevations, project boundaries, sloping design lines, and borings as you go.
- Existing and proposed surfaces in one project
- One-click contour takeoff from vector PDF and DWG
- Trace contour lines from raster drawings
- Pick the elevation at any point on the 3D surface
Cut, fill, sub-grade, and trench, all priced.
Calculate net earthwork between the existing and proposed surfaces, then break the site into zones to balance the dirt. Sub-grade, over-excavate and backfill, trenches, and topsoil strip and re-spread come out as separate quantities.
- Cut, fill, and sub-grade material volumes
- Over-excavate and backfill volumes computed automatically
- Trench materials and volumes disclosed separately
- Topsoil strip and re-spread, with the option to exclude regions
- Boring log input for cut volumes by soil type
- Site balancing adjustment built in
Hand the takeoff to whoever needs it next.
Push results to Microsoft Excel, Word, or PDF for the bid package. Export the takeoff itself as a DWG, or push GPS surface model points as a CSV or DWG for the field. SiteWorx is cloud storage capable, save the project to any cloud drive.
