FROM THE FOUNDER
Built by someone who knows the job
I'm Tim Canavan, Director of Grand Metalworks Ltd.
I developed GrandVerify after years of taking site measurements, returning to the office and having to reconstruct the survey information into drawings.
The problem was that you couldn't always identify missing or incorrect measurements until you were back at your desk.
GrandVerify was built to bring that reconstruction and verification process onto site, while the opening is still in front of you.
Measure. Draw. Verify.
NEW IN GRANDVERIFY 1.3
From the first post
to the last check.
Mark from either end.
Set a minimum or maximum bay spacing, then read each post centre from the start or end of the run.
Choose the precision.
Use half-millimetres on site or choose a finer display for fabrication. Saved measurements keep their original values.
Check your own points.
Pick the dimensions you measured on site. Complete & Export takes you through the finished opening documents.
