AI review · 49-point checklist by a Ph.D., P.E.
AI NEC Pre-Check
A structured pass over your drawings before the plan checker sees them.
- From $49

- Checklist points
- 1 day
- Typical turnaround
What it's for
We read your drawing set for the mismatches, marking gaps, and clearance issues a plan checker is likely to flag — before you submit.
Who it's for
Built for the people who sign off
The contractor about to submit for permit
Catch comments now, before the correction cycle starts.
The design engineer sealing the set
Surface schedule-to-one-line mismatches before a plan checker does.
The manager who has to staff the check
Free your senior engineers from paging through panel schedules.
The owner’s representative reviewing a submittal
Know what a reviewer will ask before you sign off on it.
What it doesn't do
Clear limits, stated up front
- Determining code compliance
- Substituting for AHJ plan review
- Arc flash incident energy evaluation (see af-study)
- Coordination study evaluation (see coordination)
A clean report is never proof of compliance.

The cost of the first pass
Your engineers should be engineering, not proofreading.
The first pass through a document is the slowest, least interesting part of review. We do that pass and hand back a list with every item tied to a page. Your engineer still makes every call.
Defaults to the $300/hr rate PEFG prices its own expert lane from. Change it to yours.
We don't measure this and won't pretend to — the default is deliberately low. Set it to what it actually takes.
- Your first pass — 2 hours at $300/hr
- $600
- AI NEC Pre-Check — Standard
- $79
- Difference, per document
- $521
Turnaround: Typically 1 business day, plus review time.
A preliminary screening, not a substitute for your review. The Engineer of Record verifies every finding, and absence of a finding is never evidence of compliance.
Why it is consistent
Every item, every time
The full checklist runs on every document, even on a deadline.
The same standard every time
Depth does not depend on who was free that afternoon.
An audit trail by default
Every finding carries its page and the checklist item behind it.
It does not get bored
Matching ninety label values to ninety study rows is where people slip.

FAQ
Common questions
Why should I upload my jurisdiction’s adopted code and amendments?
Because it is the difference between a citation and an opinion. This is the only one of the six products whose code grounding comes from a document you supply. Upload the adopted edition or your AHJ’s amendments and findings cite the article and section from your document. Upload nothing and the review runs in degrade mode: findings are still produced, but as general engineering observations with no article number and confidence capped at medium. It will never cite a code section from memory.
Is this a code compliance determination?
No, explicitly not. Determining code compliance is reserved to the Authority Having Jurisdiction, and substituting for AHJ plan review is out of scope by design. This flags conditions worth a second look before you submit. Absence of a finding is not evidence of compliance.
Which code edition does it check against?
Whichever one you tell it at intake — NEC 2014 through 2026 — and, where you upload them, your local amendments. Adoption varies enormously by jurisdiction, which is exactly why the edition is a required intake field rather than an assumption.
Who wrote the 49 checks?
Jay R. Prigmore II, Ph.D., P.E. — a Ph.D. electrical power engineer holding twelve state professional engineering licenses and a founding member of the NFPA technical committee on electrical inspection practices. The checklist is original prose describing what to look for; it contains no reproduced NEC text and no numeric thresholds, because thresholds vary by adopted edition.
Does it review arc flash or coordination?
No — those are separate products, deliberately. Incident energy belongs to the AI Arc Flash Study Review and protective device settings belong to the Coordination & Selectivity Review. Buying one does not buy an opinion on the others.
