Cut & Fill Surveys
Compare the surveyed surface with the required reference and quantify the difference.
Cut and fill analysis
Cut and fill surveys compare defined 3D surfaces to calculate where material is above or below the reference condition and to quantify the resulting earthworks.
Common comparisons include existing ground to design, current ground to formation, date-to-date progress and selected construction layers where the required reference surface is available.

Check common basis
Confirm coordinates, levels, extents and revision information.
Survey current condition
Capture the required site surface and relevant boundaries.
Build comparison
Create the 3D surface comparison and calculate the defined quantities.
Review
Check boundaries, exclusions, design revisions and calculation assumptions.
Issue
Provide mapped difference information, quantities and agreed surface/CAD data.
Cut & Fill Surveys FAQ
What surfaces can be compared in a cut and fill survey?
Typical comparisons include existing ground versus design, current ground versus formation, current ground versus finished level, or one survey date versus another. The correct surfaces depend on the construction question being answered.
Can cut and fill be used for progress measurement?
Yes. Controlled surveys taken at defined stages can be compared to quantify earthworks change and progress across the measured area.
Can the comparison be supplied as a 3D surface?
Yes. Where required, the current, reference and/or comparison data can be supplied in compatible CAD or surface formats as part of the agreed deliverables.
