Volumes you can trace back to the survey

Keep the surface, boundary and measurement assumptions with the result.

Illustrative construction workflow
Illustrative image, not a client project.

Agree the measurement basis

Identify the survey date, base surface, boundary and units. Make exclusions and inaccessible areas visible in the report.

Keep volume and mass separate

Record any supplied density or conversion factor and its source. Do not insert a generic wet-season adjustment into a project calculation.

Make comparisons repeatable

Keep the source files and calculation version. When comparing surveys, explain any change in the boundary, base surface or method.

General preparation notes. Confirm the requirements, methods and approvals for your project with the responsible team.
