On a construction project, drawings get updated again and again. A wall moves, a door changes size, a room gets split in two. Each new version is supposed to be clearly marked, but in real life, changes slip by, especially when everyone is busy.
Building from an old sheet costs time, money, and patience.
Why comparing drawings is hard
Spotting the difference between two sets of plans by eye is slow and tiring. Small changes are easy to miss, and two people may notice two different things.
How software can help
Software can read floor-plan drawings, pick out walls, doors, windows, and rooms, and compare one version to the next. It can list what moved, what was added, and what was removed, and show why it thinks so.
The goal isn’t to replace the project manager’s eye. It’s to make sure nothing slips past it.
People still decide what matters
Not every change is important. A project manager should review the list, confirm which changes matter, and decide who needs to know. Then a short, clear summary goes to the crew.
- Compare every new version, not just the “big” ones.
- Keep a record of what changed and when.
- Send crews a simple list of changes, not a whole new drawing set.
- Make one person responsible for confirming changes.
PlanProof is designed for this: reading drawings with set rules and showing why it made each choice.
