Industry Report · 2025

The spec-hunting tax every firm pays.

Based on surveys of 1,200 AEC professionals across 340 firms. The numbers are not abstract — they are your calendar.

0.0hrs

Lost per architect per week

hunting specs, codes, and submittals across disconnected sources

$0

Average billable rate per hour

meaning every week of spec-hunting costs a firm $2,100+ in recoverable time

0+

PDFs in the average project folder

with no cross-referencing, no version tracking, and no search
