Sheet index validation
Verify that your sheet index matches the actual drawing set. Catch missing sheets, duplicates, mislabeled pages, and revision date inconsistencies in seconds, ensuring your drawing set is complete and correctly organized before it leaves the office.
Why index validation matters
Small index errors compound across large multi-discipline drawing sets.
From PDF upload to index report
Helonic compares every sheet in the PDF against the index in seconds.
Upload drawings
Drop your complete PDF drawing set into Helonic. We read the sheet index page and every individual sheet in the set.
Index extraction
AI reads and parses the sheet index, extracting sheet numbers, titles, revision numbers, and dates from the index table.
Sheet matching
Every sheet in the PDF is matched against the index. Title blocks are read to confirm sheet numbers, names, and revision information.
Discrepancy report
Receive a clear report of missing sheets, extra sheets, mismatched titles, duplicate numbers, and revision inconsistencies.
What we check
Every type of index discrepancy hidden in large sets.
Missing sheet detection
Identifies sheets listed in the index but absent from the PDF, and sheets in the PDF not listed in the index.
Duplicate sheet flagging
Catches duplicate sheet numbers that create confusion about which version is current.
Number format validation
Verifies consistent numbering conventions (e.g., A1.01 vs A101) across the entire drawing set.
Revision date consistency
Confirms that revision dates in title blocks match the sheet index and are logically sequential.
Title block verification
Cross-checks project name, project number, architect of record, and date across all title blocks for consistency.
Why this matters
An incomplete or incorrectly indexed drawing set causes problems from day one. Contractors working from a set with missing sheets will encounter gaps in information, leading to RFIs, work stoppages, and incorrect assumptions. A sheet numbered A2.01 in the index but labeled A2.1 in the title block creates confusion about which sheet is being referenced in submittals and field reports.
These seem like small errors, but they compound. On a 200-sheet set with multiple disciplines and consultants, maintaining a perfect index manually is nearly impossible, especially under deadline pressure. Helonic checks every sheet against the index in seconds, giving you confidence that your set is complete and correctly organized.
