A review comment that says "egress width may be insufficient" is almost worthless. A comment that says "corridor width at grid line B-4 measures 42 inches; IBC 2024 Section 1020.2 requires a minimum of 44 inches for corridors serving an occupant load greater than 10." That's a comment you can act on.

The difference is specificity. And in construction drawing review, specificity isn't just about being helpful. It's about traceability, liability, and getting through permit review without unnecessary correction cycles.

Vague comment
"Check egress width. May not meet code."
No location. No code section. No required dimension. The designer doesn't know where to look or what to fix.
Actionable comment
"Corridor at B-4: 42" width. IBC 2024 §1020.2 requires 44" min. Widen to 44" or verify occupant load <10."
Specific location, code reference, measured value, required value, and resolution path.

What AHJs actually want to see

When you submit drawings to the authority having jurisdiction, the plan reviewer on the other side is checking your documents against the same code sections you should have checked. If they find a violation, they'll cite the specific section in their correction notice. If your own QA/QC review caught the issue first and documented the resolution, you've saved everyone a round trip.

Round-trip math
Each AHJ correction cycle adds 2 to 4 weeks. A review that catches 80% of the corrections before submittal can save 1 to 2 full cycles, along with the fees that come with them.

The liability dimension

When a PE stamps a drawing set, they're attesting that it complies with applicable codes and standards. If something goes wrong, the question becomes: what did the PE check, and how did they document it?

A review record that says "reviewed for IBC compliance: pass" provides almost no legal protection.

A review record that documents specific findings, specific code sections, and specific resolutions demonstrates due diligence. It shows that the PE applied professional judgment to identified issues, not that they rubber-stamped the set.

What a useful review comment looks like

A good review comment has four components:

Component
Location
Where on the drawings
Finding
What's the specific issue
Code reference
Which section, which edition
Resolution
What would fix it
Example
Sheet M-101, AHU-1 schedule
Equipment efficiency not listed
ASHRAE 90.1-2022 Table 6.8.1-1
Add IEER rating to schedule; min 12.2 for this capacity range

The difference between a helpful review and an unhelpful one usually isn't knowledge. It's the time it takes to document each finding at this level of detail. Which is exactly why automated first-pass review has value: it generates the detailed, citable findings at machine speed, and the PE focuses on verifying and adding judgment.

Severity matters too

Not all code violations are equal. A missing fire damper at a rated assembly is a life-safety issue that will block a permit. A thermostat location that doesn't match the specification is a coordination note that can be resolved during submittal review.

Critical
Safety hazard or permit blocker. Must be resolved before submission.
Major
Code violation requiring a design revision. Will likely be flagged by the AHJ.
Minor
Technical issue or documentation gap. Should be corrected but won't block a permit.
Advisory
Best practice recommendation or coordination note. Not a code violation.

Severity classification helps the PE and the design team prioritize their response. When you're looking at 80 review comments on a large drawing set, knowing which 5 are critical lets you allocate your time where it matters most.

Documentation as a deliverable

Some firms treat the review record as an internal tool. Others include it in their QA/QC deliverables to clients. Either way, a structured review with specific citations has value beyond the immediate correction cycle: as a training record for junior engineers, a project-specific code analysis for CA, and an audit trail for insurers and legal counsel.

The difference between "reviewed" and "reviewed with documented, citable findings" is the difference between checking a box and building a professional record.
