Catch it in review.
Not in the field.
CivilPlanAI is automated quality assurance (QA/QC) for civil engineering plan sets. Upload a set and a team of specialized AI reviewers checks every sheet — grading, drainage, code, coordination, the small stuff — pins each issue to the drawing, and hands you a marked-up set you can review in minutes. You have the final say.
Currently onboarding a small group of firms. No demoware — real plans, real findings.
You already know
where the errors hide.
It's sheet 9 of 14, 11 p.m., the deadline's tomorrow. The grading callout that doesn't match the profile. The detail that references a sheet that got renumbered three revisions ago. The inlet the lot slopes away from.
None of it is hard to catch. It's just hard to catch everything — on every sheet, every time — after six hours in the set. Manual QA is 4–8 hours you don't have, and the one thing you miss is the one that comes back as a field RFI.
What if every set got a full, consistent review — in minutes?
Not a spell-checker. A review that checks grading, drainage, accessibility, standards, and cross-sheet coordination — and tells you exactly where to look and why.
How it reviews your plans
Everything that happens between your upload and the set you get back.
It reads the actual drawings
Not the text layer, not metadata — a vision model that sees the linework, the callouts, and the elevations the way a reviewer does. And where the drawing states its own numbers, it doesn’t estimate: it pulls the inverts and run lengths off the sheet and does the arithmetic.
A team of specialists, not one generalist
Separate reviewers for grading & drainage, standards & code, quality, and cross-sheet coordination — the way a real firm splits a review. Each one is sharp at its discipline.
It always checks its own work
Before a single finding reaches you, it’s been cross-examined and reconciled — so what you get is signal, not a wall of false positives.
Everything is traceable
Every finding is pinned to a sheet, a location, and — where it applies — a code reference and a confidence level. Nothing magical. Nothing you can’t verify.
It reviews to your jurisdiction, not a national average.
It works out who actually has authority over your project — the city, the county, the district they defer to — and which codes each one has adopted. Your own design manual and standard details sit alongside them. You confirm it, correct it, or add what your team already knows.
Every entry shows where it came from: a link to the published ordinance, a standard inherited from the authority above, or your engineer’s own entry. When something isn’t found, it says so — it won’t invent a code section to fill a gap.
Reading the code portal, the county and the state.
What a finding looks like
No black box. Here's the detail you get on every issue — and the call is always yours.
It drafts; you decide. You approve, edit, or reject each one.
An error caught in review is cheap. The same error in the field isn't.
A missed slope, a setback that doesn't meet code, a detail that conflicts with the utility plan — caught in QA, it's a five-minute fix. Caught in construction, it's an RFI, a change order, a delay, and a conversation with the client you'd rather not have.
CivilPlanAI exists to keep errors on this side of the bid set.
You're still the engineer of record.
CivilPlanAI doesn't stamp anything and it doesn't overrule you. It surfaces issues, shows its reasoning, and lets you decide what's real — the most consistent junior reviewer you've ever had, one that never gets tired, never skips a sheet, and holds the same line on set #1 and set #100 — and the line it holds is the one you drew.
You work the queue.
Traceable by design
Sheet, location, code reference, confidence — every finding shows its work.
You approve every finding
Nothing is acted on until you say so. It drafts; you decide.
Your plans stay yours
We don't train on your data, and we don't share it. Your plans are yours.
It learns your line
Reject the same false positive enough times and it offers you a rule. You approve the wording — it applies to every set after.
Built for the people who actually run the review.
Get the set out the door without staying late.
Get hours back without lowering the bar on QA.
Stop maintaining 15 checklists.
One review standard across every project and every reviewer.
Know every set meets your standard before it leaves the office.
A consistent, repeatable quality process you can put your name behind. Reviewing a subconsultant's set? Flag issues before you stamp.
We're working with a handful of firms first.
CivilPlanAI is being shaped right now, alongside a small group of civil teams who care about getting plan review right. If that's your firm, we'd like to hear from you — what you review, where it hurts, and what good looks like to you. No pitch deck. A real conversation.
Let's talk about your plan sets.
