Validate changes visually without flipping between drawing sets.
Toggle the color-coded overlay to see what's new in green and what's been removed in red.
Revision management
Get all the changes for your change order.
When drawings change, SketchDeck identifies what's different, updates your quantities, and generates the documentation you need to price the change.
The problem
Every missed change can cost your team thousands of dollars in lost profit.
Manually itemizing changes every time an addendum comes in.
One missed change means bidding at the wrong price.
Fast turnaround pressure is high on rebids/change orders.
It takes four to five bid cycles on average to win a structural steel job. That's before post-award change orders even start. Every revision means stopping what you're doing, finding the changes, and turning around an updated price while work continues to pile up.
How it works
Create and compare changes across every revision.
01
Upload your revised drawings
Add the new set to your existing SketchDeck project. Processing takes about one to two minutes per page for automated analysis.
02
SketchDeck identifies every change
AI compares the two sets member by member. Adds, deducts, and modifications are flagged automatically. Toggle the overlay to validate: green means new, red means removed. Click any member in the table to locate it on the drawing.
03
Review, validate, and export
All your previous estimate work carries over. Grades, finishes, categories, and any other fields you add. SketchDeck only touches what changed. Export a full BOM or just the changes.

What this means for your team
For Estimators
When addenda arrive mid-bid, SketchDeck updates your quantities and tracks the changes. Spend your time on pricing, not re-counting.
For Project Managers
Every change is tracked with a before-and-after record. Export a clean delta report to justify pricing to the GC and owner.
For Operations Leaders
Fewer missed changes, faster turnaround, and a consistent process across your project portfolio.

How long does it take to process revisions?
About one to two minutes per page.
What types of members does it cover?
Beams, columns, and joists. Sections, details, and misc metals aren't covered yet.
Does it work for both addenda and change orders?
Yes. Any time revised drawings are issued, pre-award or post-award.
Will it overwrite my previous estimate work?
No. Grades, finishes, categories, copes, and holes all carry over. SketchDeck only updates what changed.
What if the AI gets something wrong?
Every status is editable, and manual changes are tracked in the same audit history.
Can I use this on jobs I've already started in SketchDeck?
Yes. Add a new version to any existing project and run the comparison against your completed takeoff.
What export options are available?
A full BOM with change status for every member, and a Delta Report with positive and negative line items for direct PowerFab import. Both include tonnage summaries.
