GUIDE: RESUBMITTALS
Why MEP Submittals Come Back Revise and Resubmit, and How to Catch It First
Once a submittal is approved, the product it describes is locked in. A mismatch caught before approval is a paperwork problem; caught after installation, it is rework (Trunk Tools, 2026-08-21). The cheapest place to catch it is before the package leaves your office.
This guide covers what the published data says about returned submittals, the five checks that catch the common causes, and how to price a return in your own numbers.

The data
What Trunk Tools platform data shows
From Trunk Tools platform data, updated 2026-08-21. These are Trunk Tools' numbers across its platform, not Submittal Desk results.
- MEP divisions run 60% to 70% non-compliance, nearly twice the rate of structural divisions; concrete is lowest at 32%.
- Across all divisions, about 55% of reviewed submittals carry significant compliance gaps and another 35% to 40% carry minor to moderate gaps.
- The single largest driver is manufacturer source: an unapproved substitution in place of the specified product.
- The median cycle from upload to design team approval is about 55 days with manual first-pass review, and about 43% of submittals take more than 60 days to close.
Before you send
Five checks that catch the common causes
- Manufacturer and model: named in the spec, or an approved substitution on the log. This is the largest single cause in the data above.
- Completeness: every item the Submittals article lists is in the package. A catalog alone is product data, not shop drawings.
- Ratings and dimensions: every value the spec states is matched to a page. In the public LAWA panelboard example, a standard 5.75 inch box against a 6 inch requirement is a deviation.
- Deviations on the cover: the GC reads them from you, not from a red markup.
- Conditions: some sections refuse review until something else is approved, such as the coordination study in LAWA 26 24 16, paragraph 1.2.C.
The cost
What a return costs you
In your numbers: returned packages, times the hours your PE spends on each, times your PE's hourly cost. A construction project engineer averages $51 an hour, $47 to $56 across the middle half of the range (Salary.com, as of 2026-09-01).
The schedule cost is larger. Each return restarts the review window, and on long-lead gear a missed approval window can lose the factory slot that set your sequence (Archdesk, 2026-04-16).
Or hand it to the desk
Catch it before the GC does
The Pre-Check runs these five checks on every package before it leaves your office, and cites the spec paragraph and package page for every finding. In the sample run, the check runs on up to 20 of your past packages that already came back, and the report counts how many of the reviewer's comments it would have flagged in advance.
Straight answers
Questions this guide answers.
- What does Revise and Resubmit mean on a submittal?
- The reviewer found problems that must be corrected, and the package has to be sent and reviewed again. The item does not proceed on the returned package, and the review starts over when you resubmit.
- What is the difference between Approved as Noted and Revise and Resubmit?
- Approved as Noted lets the item proceed with the reviewer's corrections applied. Revise and Resubmit does not; the package must be corrected and reviewed again first.
- What is the most common reason MEP submittals are rejected?
- In Trunk Tools platform data, the single largest driver of non-compliance is manufacturer source: an unapproved substitution in place of the product the spec names (updated 2026-08-21).
