AI calls out the changes
Upload a new revision and AI compares it against the last, calling out what changed so the moved wall gets caught in review.
Use case
Construction version comparison that shows what changed.
Drop in revisions, compare the sheets, and turn drawing changes into a markup or structured data your team can actually use.
Why teams use it
Organized around the sheet set.
Every version kept
Old sets stay archived and comparable; the current set stays unmistakable. Nobody marks up a superseded sheet.
Share the finding
Markups on the change live on the sheet, and a live share link puts the diff in front of the architect or owner immediately.
FAQ
Questions this page should answer.
What does construction version comparison do?
It compares drawing revisions so teams can see what changed between one construction PDF and the next. In Redliner, AI runs the comparison and calls out the changes.
Who uses drawing version comparison?
PMs, architects, estimators, supers, trades, and owners use it to understand scope changes and avoid missed updates.
What happens to old versions?
Redliner keeps every uploaded revision available for reference and comparison while the current set stays clearly marked.
