Plan Review Comments Are Back. Here Is How to Update Your MEP Drawings Without Creating New Ones
AutoMEP Team,
Plan review comments are not a rejection of your design, they are a punch list for your drawing set
When plan review comments come back, update your MEP drawings by triaging every comment first, fixing code and coordination items before cosmetic ones, carrying each fix through every affected sheet, schedule, and detail, and then reissuing a clean, checked set with a clear response to each comment. That order matters, because a fix that lands on one sheet and not the rest is exactly how a second round of comments starts.
Most resubmittals go sideways when a drafter fixes the sheet the comment points to, while the same tag, pipe size, circuit, or clearance still shows the old value on a schedule, a riser, or a detail. Reviewers notice that drift, and so do contractors, because they build from the whole set. Treat every comment as a search through the set, not as a single edit.
What should you fix first when plan review comments come back?
Start with anything that affects life safety, code compliance, or the ability to build the system as drawn. That includes access clearances, ventilation rates, electrical loads, plumbing fixture counts, and any dimension that decides whether equipment actually fits. These items decide whether the set can be approved, so they outrank notes and legend cleanup, even when the cosmetic items are easier to close out.
Next, group the remaining comments by system and by sheet, not by the order they appear in the review letter. A diffuser comment, a duct size comment, and a ceiling clearance comment may all trace back to one ceiling plan change, and fixing them together keeps the set consistent. If two comments conflict, flag it now, rather than guessing.
How do you keep one correction from breaking another sheet?
Build a simple cross reference before you touch a drawing. For each comment, list the plan, the schedule, the detail, and the note that carry the same value, then check each one off as you update it. This step prevents the most rework, because MEP values rarely live in one place. An equipment swap changes a tag, a schedule row, and a connection detail. A pipe size change moves through plans, risers, and schedules. A lighting change moves through ceiling plans, circuiting, and panel schedules.
Use the same discipline for tags and leaders. When a room number, an equipment tag, or a circuit number changes, search the whole set for the old value, including details and keynote legends that drafters sometimes forget. A legend that still shows a superseded symbol will confuse a reviewer just as much as a wrong plan. Close the loop on every tag you touch, then read the affected sheets as a reviewer would, checking that the story matches throughout.
A repeatable resubmittal workflow
First, log every comment with its sheet, system, and disposition, so nothing gets answered from memory. Second, make the edits in a consistent system order. Third, run a second pass that looks only for consistency, checking tags, sizes, loads, flows, and clearances against each other. Fourth, update the title blocks and revision tables only on the sheets you touched, so the revision history tells the truth.
Fifth, write a response that points to the exact sheet and detail where each comment was addressed, using the reviewer's numbering so they can verify it without hunting. Reviewers reward a response they can check quickly. For teams that handle these edits in AutoCAD or Revit, describing the change in plain English and letting an AI drafting agent carry it through the set can remove a large share of the manual drafting hours that resubmittals usually consume. AutoMEP works this way, you upload a DWG or RVT file, describe the edit in plain English, and it returns a native DWG or RVT file that opens in AutoCAD or Revit, with no install, no plugins, and no macros. It supports DWG 2007 and later, plus Revit 2024, 2026, and 2027, and a licensed professional should still review the edited drawing before anyone builds from it.
What reviewers check on the second pass
On a second pass, reviewers check whether your answers created new problems. They look for schedules that no longer match plans, details that still show the old condition, and notes that contradict the corrected layout. They also check consistency across disciplines, because a duct move can easily crowd an electrical route or a plumbing run that nobody rechecked. That is why the consistency pass matters, and why coordination stays with your own review and tools.
If a resubmittal needs a short walkthrough video so the reviewer or the owner can see what changed, a studio like Envy Creative can present that walkthrough clearly, but the drawing set itself still has to carry the full technical answer. Video explains, drawings decide, and reviewers approve drawings. Keep that order straight.
Common traps that earn a third round
One trap is leaving the revision note vague, so the reviewer cannot tell what changed. Mark every change clearly, and make the revision table match the clouds. Another trap is updating a plan and forgetting the riser diagram. A third is answering with a note instead of a drawing change, when the reviewer asked for a drawing change. Notes help, but they do not replace corrected geometry, tags, and schedules.
Closing the loop
A clean resubmittal is a habit. Log the comments, fix in system order, carry each fix through every sheet and schedule, mark the changes clearly, and answer each comment with a sheet reference. AutoMEP starts at $39 per month for Starter, $99 per month for Pro, and $249 per month for Team, with a 7 day free trial on all plans, so a firm can test the workflow on a real resubmittal before committing.
Frequently asked questions
Should I answer every comment, even the ones I disagree with?
Yes, answer every comment, including the ones you disagree with, and explain your reasoning with a sheet reference. Silence reads as an oversight, while a reasoned response gives the reviewer something to evaluate.
How do I know the set is ready to reissue?
The set is ready when every comment has a disposition, every fix appears on every affected sheet and schedule, and the revision tables match the clouds. If any check fails, fix it before you send the set out, because a reviewer will find it.
