AI Drafting for Plan Check Corrections

A correction list from the building department can run to 60 comments across architectural, structural, MEP, and energy, and the permit does not move until every one is answered on the drawings and in the letter. Nomic reads the comments, revises the affected DWGs, clouds each change with the resubmittal delta, and drafts a response letter that points the plans examiner to the exact sheet and detail for each item.

You send

  • The correction letter or plan review portal export
  • The permit set as DWG files, with PDFs of any sheets you do not draw
  • Your CAD standards for clouds, deltas, and revision blocks
  • The code editions the jurisdiction has adopted

Nomic hands back

  • Revised DWGs with each fix clouded and tagged with the resubmittal delta
  • A response letter keyed to every comment, sheet, and detail
  • Plotted resubmittal PDFs with updated revision blocks
  • A list of comments that need a decision from the architect or engineer

The problem

Sixty comments, five disciplines, one resubmittal

Correction comments arrive as a PDF or a portal export, numbered by reviewer and discipline, and many of them are small: add the available fault current to the one-line, show the grab bar lengths on the enlarged restroom plan, reference the fire-rated assembly at the corridor wall. Each small comment still means opening a sheet, drafting the fix, clouding it, adding a delta to the revision block, and writing one line in the response letter that says where the fix is.

The common failure is drift between the drawings and the letter. A response says see detail 7/A-501 when the detail landed on A-502, a cloud is missing its delta tag, or a comment marked revised was never drafted, and the plans examiner issues a second round of corrections that costs the project another review cycle.

01 / Read

Every comment sorted to the sheet it touches

Attach the correction list and the permit set. Nomic splits the comments by discipline, ties each one to the sheet, detail, or schedule it refers to, and separates the drafting fixes from the comments that need an engineering or design decision before anyone draws.

  • Comments parsed from PDF letters and portal exports
  • Each comment tied to the sheet and code section it cites
  • Design decisions separated from straight drafting fixes
02 / Revise

Fixes drafted, clouded, and tagged with the delta

Nomic edits the DWGs for each drafting fix, draws the cloud, places the delta tag, and adds the resubmittal row to the revision block on every sheet it touched. The response letter is written from the same edits, so each answer points to a sheet and detail that actually exists in the resubmittal set.

  • Clouds and delta tags on every changed area
  • Revision blocks updated on each reissued sheet
  • Response letter keyed comment by comment to sheet and detail
03 / Check

Checked against the comment and the code it cites

Before the resubmittal goes back, Nomic checks that each fix satisfies the code section the reviewer cited and that every comment marked revised has a cloud, a delta, and a matching line in the letter. Anything still open stays open in the letter so the plans examiner is not surprised.

  • Each fix compared with the code section in the comment
  • Letter, clouds, and revision blocks cross-checked for drift
  • Open items listed for the architect or engineer of record

Checked against

The code and documents behind every sheet

Name the editions the project is designed to and Nomic checks its own drawing against them before handing it back. Your engineer or architect of record makes the final call and stamps the set.

  • The building department correction list
  • International Building Code as adopted by the jurisdiction
  • NEC (NFPA 70)
  • 2010 ADA Standards and ICC A117.1
  • IECC or ASHRAE 90.1 energy provisions

How it works

From a sentence to a stamped set

  1. Step 1

    Ask for the drawing

    Say what the sheet needs to show and attach the backgrounds, markups, cutsheets, or photos. A sentence is enough to start.

  2. Step 2

    Nomic drafts it in CAD

    Nomic works in CAD on its own computer, on your layers and blocks, following how your firm drew the same thing before. It saves real DWG files to the project.

  3. Step 3

    Nomic checks its own work

    The drawing is checked against the code editions you name and the source documents. Everything Nomic drew is clouded, and open questions are listed.

  4. Step 4

    Your team reviews and stamps

    Your engineers and architects review the clouded changes, make the final call, and issue the set under their own stamp.

FAQ

Frequently asked questions

Revise the drawings for each comment, cloud the change, add a delta to the revision block, and write a response letter that restates each comment and says exactly where it was addressed. Comments you disagree with get a written justification with the code section. Nomic drafts the drawing fixes and the letter, and your architect or engineer of record reviews and signs.

Yes. Nomic drafts the letter from the same edits it made to the drawings, so each response cites a sheet and detail that exists in the resubmittal set. Your team edits the wording and signs it.

Nomic flags them instead of guessing. A comment asking to justify a corridor rating reduction or resize a feeder stays open in the letter until the architect or engineer of record decides, and Nomic can draft the fix once that decision is made.

Nomic checks each fix against the code section the reviewer cited and the code edition you name, and lists anything it could not confirm. The plans examiner still makes the final determination, and your licensed professional answers for the drawings.

No. Nomic hands back the revised DWGs, plotted PDFs, and the response letter. Your team uploads the resubmittal to the jurisdiction.
