Upload drawing revisions. Varix highlights every change, quantifies it, and creates evidence-grade reports — in seconds, not hours.
"Between Rev 114 and Rev 121, there were 63 changes. 4 were claimable. The rest got missed as 'coordination.' That's profit left on the table."
— Senior QS, Major UK Contractor
