Measure once.
Capture the opening where it exists.
GrandVerify captures an opening on site, builds the digital record from that survey, and checks it independently — without recreating the same measurements back in the office.
See the complete GrandVerify workflow — from establishing the datum and capturing site measurements, through opening reconstruction and independent verification, to the final PDF and DXF files.
GrandVerify Full Workflow — approximately 5 minutes
A survey shouldn't need to be recreated before it can be used. Measurements captured on site are too often transferred and re-entered back in the office — adding time, duplication, and another chance for error.
The information captured on site becomes the information available in the office, without being recreated.

Capture the opening where it exists.

The survey becomes the digital record.

Verify what was built against what was captured.

Record the opening, holes, and cut-outs on site. A mandatory photograph provides visual context alongside the survey.

Creates the digital opening, runs independent verification checks, and makes the survey available to the office.

Gets the survey information without recreating the opening from a separate set of notes or measurements.
If the office can review the survey while the surveyor is still on site, there's an opportunity to check any questions there and then, rather than discovering them after the surveyor has left.


A mandatory photograph accompanies the completed survey, giving the office visual context alongside the measured opening — and a record of site conditions at the time of survey. The measurements show what was captured. The photograph shows what was there.
GrandVerify doesn't simply repeat the measurements entered by the surveyor. It uses the completed geometry to generate independent check dimensions that can be physically measured against the real opening before leaving site.
This gives the surveyor an opportunity to confirm that the reconstructed opening agrees with the physical opening before the survey is completed.
The information captured on site becomes a usable digital project record, without recreating the opening from a separate set of survey notes.
Reconstructed opening geometry that can be taken into the office and used in the drawing workflow.
A clear record of the opening geometry and the dimensions used to verify the completed survey.
A timestamped photographic record provides visual context and records the visible site conditions at the time of survey.
Additional site information can be retained with the opening, keeping the relevant project information together.
