Miju LabsOne number decides whether you read this page: $95–$170 an hour.
Mercor's civil engineering listing — work described as "for one of the world's top AI companies", 4+ years' experience, 15 hrs/week minimum, a 3–4 week project, US/UK/Canada only — pays $95–$170/hr (Mercor). Against a BLS architect median of $99,280/yr, roughly $47.73/hr, that is a 2–3.5x multiple on the day job: the widest wage arbitrage anywhere in this research, wider than medicine, law, banking or code.
And the same posting contains the sentence that quietly settles the legal question for this entire atlas: "No access to confidential employer information required." The industry has already converged on reconstructed work rather than exfiltrated work. That single line is why AEC is buildable at all, and it generalises — it is the same construction that rescues Law, Accounting, audit and tax and Defensive security.
Nobody is selling into it. Neither the 37-vendor RL-environment directory nor the top-50 human-data listing contains an AEC vertical (rl-list, alignlist). The AEC AI boom is entirely on the application side — $616M into AI construction startups in H1 2026 per Memoori [WEAK — trade press] (Memoori), plus rounds like Build's $8.5M seed (AEC Magazine). Every one is a potential customer. None is a data supplier.
What the data actually is
Code compliance — valuable because codes are adversarial documents, rule sets written to be argued with by people who are personally liable for the argument.
AECBench proves the artefact is legible to buyers. Built by Tongji University's College of Civil Engineering, the Shanghai Qi Zhi Institute and Arcplus Group — a real design institute, so there is genuine industry co-authorship — it is 4,800 questions across 23 tasks at five cognitive levels, drawn from "building codes, proprietary internal materials, and licensure examinations", with two-round review by mid-level and then senior 10+ year engineers. DeepSeek-R1 led on 14 of 23 tasks, but every model scored below 60% on document generation (AECBench paper).
That is the clearest "credible, unsaturated, and built by someone who is not a Western vendor" situation in this set. And it leaves the obvious product untouched: a US and EU code-compliance benchmark — IBC, ASCE 7, NEC, ASHRAE 90.1 — does not exist in public. A [NOTHING FOUND], and a product specification at the same time.
Beneath the benchmark, four lines:
| Line | Input | Why it is scarce |
|---|---|---|
| Code-compliance verdicts | Constructed plan sets against adopted codes | The answer depends on jurisdiction and on which official you draw |
| Constructability review | A design set plus a builder's read | The clash the drawings do not show |
| Structural judgement | A load path and a PE's narration of what governs | Which failure mode binds, before any calculation |
| Licensure-exam reasoning | PE and ARE problems worked with reasoning preserved | The exam tests judgement; the answer key does not record it |
Proof scores 4. There is a public number to beat, no competitor, and an entire jurisdictional benchmark category open — one notch below Video, motion and VFX only because AECBench's authors have institutional depth you would have to match.
Is anyone buying
Budget scores 3, and the honest read is that one purchase is not a line item.
The Mercor posting proves a lab bought civil-engineering reasoning once, at a good price, through an intermediary. It does not prove recurrence. Against it:
- GDPval covers neither architecture nor construction among its 44 occupations (OpenAI) — it does cover mechanical and industrial engineers, which is why Mechanical CAD and manufacturing scores a point higher here.
- No frontier lab posts an AEC subject-matter-expert role. Compare Investment banking and financial modelling, where OpenAI has a named permanent SME headcount at $185–205K.
- When xAI enumerated the domains it was surging specialists into, it named STEM, finance, medicine and safety. Not construction.
No system card, model release or disclosed contract cites purchased AEC expert data. The entire demand case here is a single recruiting page with a pay band, plus a benchmark methodology section written in Shanghai. That is weaker evidence than Clinical medicine or Offensive security carry, and you should price the risk accordingly: the $95–170/hr band tells you what a lab paid, not that it will pay again.
What partially offsets it is the shape of the buyer. A $170/hr rate through Mercor means the end customer pays meaningfully more, and Mercor does not run 3–4 week projects at that band on speculation. Somebody's evaluation budget cleared it.
Getting the experts
Reach scores 5, and AEC is one of only three domains in this atlas with a public register of verified practitioners — the others being CPAs at NASBA (Accounting, audit and tax) and state bar admission (Law).
NCEES and the state PE licence registers are public and searchable, jurisdiction-tagged, with standing visible. NCARB covers architects. Beyond the registers: AIA chapters; ASCE and ASHRAE; Autodesk Revit forums, where the people who actually produce documents congregate; r/architecture and r/StructuralEngineering; BuiltWorlds.
BLS counts 124,600 US architects at $99,280/yr, growing 4%, with civil and structural engineers adjacent (BLS Occupational Outlook Handbook; the research captured no URL for these figures, so treat the citation as second-hand).
The pitch writes itself. A licensed engineer earning $48/hr, offered $120/hr for evaluation work with no confidential material involved, does not need persuading. This is the cheapest supply acquisition in the set.
What it costs to run
Cost scores 4. No rig, no lab, no building — worth stating plainly in a domain literally about buildings. The work is documents.
Two real capital lines, both modest. Software seats: Revit and AutoCAD licences per seat per year, the same low-thousands territory as Mechanical CAD and manufacturing's SolidWorks; your experts already have employer seats, you need a handful for reference work. Code books, which are not free: ICC, NFPA and ASHRAE sell the model codes and you need current editions across every jurisdiction you cover — a recurring four-to-five-figure line, and, as below, a legal exposure rather than merely a cost.
Against a $47.73/hr floor, paying $120–140/hr still leaves room under a sell price in the range Mercor's band implies. The spread is better than Law's and far better than Clinical medicine's, because the floor is low and the observed clearing price is high at once. That combination appears exactly once in this atlas.
Who is already there
Room scores 5. There is no AEC data specialist, and the application companies absorbing the $616M consume engineering judgement internally rather than selling it.
Defense scores 4. PE and RA credentials take years and cannot be faked; codes are revised on published cycles, so a 2026 compliance dataset is wrong by 2029 whether or not anyone competes with you; and the stamping regime that caps your product also deters casual entrants.
What would kill it
Stamping liability, which is a boundary rather than a risk. A PE or RA seal is a personal, statutorily defined act of professional responsibility, documented across all fifty states by the ABA Forum on Construction Law (50-state survey). Your experts will happily evaluate AI output as a side gig. The moment a customer asks for AI-generated stamped drawings, the liability chain breaks. Sell judgement and evaluation. Never production. Assume that ceiling from day one and it costs nothing; discover it in month eight and it costs the roadmap.
The lab never comes back. One Mercor project is not a market. If AEC evaluation was a one-off procurement for a specific model release, budget here is a 2, not a 3.
A horizontal notices the rate. Mercor is already running this work. Adding AEC depth is a recruiting sprint for them, and they have the customer relationship you do not — see Which side you build first.
ICC, NFPA and ASHRAE assert copyright in model codes even where jurisdictions adopt them by reference. Building a compliance benchmark on verbatim code text is legally fraught; building it on problems derived from code is not. The research did not source a 2026 ruling or position statement on this — it is [UNVERIFIED] and it is live. One court opinion or one publisher licensing programme resolves it in either direction, and the direction changes whether the US-code benchmark above is a product or a lawsuit. Get an opinion before you draft a question.
The first ninety days here
Pull the NCEES and state PE registers, cross-reference AIA chapter rosters, and recruit 40–60 licensed engineers and architects — weighted toward code consultants and plan reviewers, who are the people paid to have exactly this opinion. Pay $120–140/hr and lead with Mercor's own "no confidential employer information" language, because it is the sentence that converts.
Then build what does not exist: a US code-compliance benchmark, derived problems only, one code family to start — IBC egress, or ASCE 7 wind — with three-reviewer grading and the disagreements published. Sit it alongside AECBench rather than duplicating it, and report where the sub-60% document-generation failure actually lives. See The first ninety days and The specialist wedge: AEC sits on the side of that trade with an open benchmark and an unproven budget, which is a real position provided you know which half you are betting on.
Where the record is thin
The $95–170/hr band is Mercor's own recruiting page. Nobody has confirmed what the end lab pays for it, so the sell-side price and the take rate are both inferred.
The Memoori $616M figure is trade press. The BLS architect numbers arrive without a captured URL. AECBench is a single paper from a single consortium and has not been independently reproduced. And the copyright question above is genuinely unresolved — of everything on this page, it is the item most likely to change the answer.
