How AI Sheet Indexing Works for Plan Review

Written by e-PlanSoft™ Team | Sep 25, 2026, 1:30:00 PM

The applicant’s sheet index lists S-02, but you can’t find it in the submitted plans. You scroll through the PDF again, checking sheet numbers and titles.

Is the sheet missing, labeled differently, or still listed on an index the applicant didn’t update?

Before you can ask the applicant to correct anything, you need to establish what’s actually wrong.

Depending on the agency, it may be up to the permit tech, intake staff, or the plan reviewer to run that check. Whoever is responsible, it’s on them to handle the back-and-forth to answer this question before the actual review begins.

We’ve written about how experienced plan reviewers get oriented before they start reviewing. Checking that the documentation is in order is part of that preparation. Discovering a missing sheet later means interrupting the review to investigate something that could have been caught earlier.

That’s where e-PlanSoft’s AI-powered sheet indexing comes into play.

Compare the Submitted Sheets With the Applicant’s Index

ePlanSoft’s AI Sheet Index Assistant answers a specific question: Do the sheets in the submitted plans match the sheets listed in the index?

e-PlanSoft’s AI assistant reads sheet numbers and titles from the plans, then compares them with the applicant’s sheet index. The AI agent then flags missing sheets, duplicates, and names or numbers that don’t match.

Remember that manual example from above? Someone is going to have to work down the index, find each sheet, and hand-check its number and title. With e-PlanSoft’s AI sheet indexing, your staff can see the matches and investigate the flagged discrepancies without lifting a finger.

Watch the short demo below for an example of a matching sheet, a sheet listed in the index but missing from the plans, and a sheet with a mismatched title.

A Practical Place for AI to Help

Rather than seeing AI as a way to replace your expertise and judgment, we’re more interested in AI that removes work from your plate that you shouldn’t be doing in the first place.

Comparing sheet numbers and titles is the kind of repetitive checking we describe in our approach to AI in plan review. The assistant does the comparison, and staff can check what it found.

Matching the index doesn’t mean a submission contains everything required for the project. Staff still need to determine whether the drawings and supporting documents are sufficient for review. But they can make that assessment with a clearer picture of what was submitted and where the inconsistencies are.

That’s the value of sheet indexing: less time reconciling the sheet list by hand, and a clearer starting point for the review.

It’s just one of the many ways we’re building AI that complements the human process of plan review.
