EXPOSED
Screeding, floating, troweling, edging and joint-cutting concrete on a clock set by the mix's cure time is almost entirely embodied craft work — language models touch none of it, and existing power screeds and troweling robots still need a finisher reading the surface by feel. The exposure is not the trowel work but everything around it: takeoffs, yardage estimating, scheduling, and bid paperwork are already being drafted by software. No license is legally required in most states, buyers rarely pick a specific finisher, and the general contractor owns the consequential calls, so the score rests almost entirely on the body.
Dipped in 2020, then grew past where it started.
Median pay $44,810 → $57,020 +1.8% in real terms
This line is counted by the Bureau of Labor Statistics — the one figure on this page that isn't a judgement of ours. Headcount moves on demand, offshoring, demographics and the business cycle, and automation is one term among several, often not the loudest.
So a falling line is not evidence that AI did it, and a rising one is not evidence that it won't. Both happen in this register: some occupations resist automation and shrink anyway, others are highly automatable and keep growing. The marked year is 2020.
BLS projection, 2024–2034
+1.8% 206,700 → 210,400 on the projections basis
Growing, and only partly exposed
The BLS expects +1.8% more of these jobs by 2034, and at 58/100 the work is only partly exposed — some tasks are automatable, the core of the job is not. Nothing here is in tension.
Different clocks. The score is what current AI could do to this work today. The projection is how many of these jobs will exist in 2034. Everything between the two — how fast employers actually adopt, whether demand grows in the meantime — is why they can point opposite ways without either being wrong.
~14,300 openings a year on average, including replacing people who leave.

Holding it up: embodiment . Weakest point: liability shield .
Tasks largely resist digitisation The core sequence — placing, screeding, bull-floating, waiting for bleed water to leave, then power-troweling to a hard burnish — is timed off a slab that keeps changing under your hands, and no software output substitutes for kneeling on a board and reading whether the surface will take a blade yet; the one point off 20 is the office side (yardage takeoffs, bid sheets, joint layout drawings) that estimating software already handles.
Hands-on in uncontrolled environments You work bent over wet mix in whatever weather the pour was scheduled for, hauling hose, running a ride-on trowel, cutting control joints with a walk-behind saw, and stripping forms on uneven ground — there is no version of this performed remotely or from a controlled bay, which is exactly what a 20 describes.
No licence, no signature requirement Most states license the contractor entity, not the finisher; ACI Flatwork Finisher certification and an OSHA 10 card help you get hired but nothing you hold personally carries statutory liability, and a failed slab becomes the GC's and the concrete supplier's fight over mix design and subgrade — the 3 rather than 0 reflects that certification is increasingly written into spec sheets on commercial flatwork.
Meaningful discretion You decide when to start floating, whether to hit it with a fresno or wait, how much to fight a hot windy day, and when to tell the truck the load is too wet to place — real calls with expensive consequences, but slump, thickness, rebar spacing and cure method come off the spec and submittal, so the ambiguous high-stakes decisions belong to the engineer and GC above you.
The verdict above describes this occupation as a whole. Almost nobody does the typical version of a job — tick what's actually in your week and see how your own mix sits.
Your task mix speaks to task resistance (19/20 here) — how much of the day's work current AI already does. That is the dimension the boxes above are about.
It cannot move the other three. Liability shield (3/20) is whether the law requires a licensed human to sign. Trust premium (7/20) is whether buyers specifically pay for a person. Judgment and accountability (9/20) is whether the role exists to own consequential calls. Those are facts about the occupation's standing, not about which tasks are in your week — a paralegal who does only trial exhibits still holds no licence. Together they are 19 of this occupation's 58 points (33%).
Embodiment (20/20) is also a property of the work rather than the worker, but we don't tag individual tasks as physical or not, so the picker can't tell you anything about it. That's a limit of this tool, not a claim.
Did we get the list right? Tell us what's missing — the tasks are written from the outside, and you're reading this from the inside.
Roofers SAFE
The moves above are yours to make. This is the other half: what would have to change in the world for the occupation itself to score higher. None of it is in any one person's gift, but it is where the floor actually comes from. Scores here are not a one-way ratchet. Only two of the five dimensions — task resistance and embodiment — track what machines can do. The other three track law, what buyers will pay for, and who is answerable, and those move in both directions, often in response to the same pressure AI creates. If every lever below landed, this occupation would score around 73/100 — SAFE.
Owner and insurer specification language — already common in large industrial and data-center slab contracts — requiring a named ACI-certified finisher present for every placement as a condition of the workmanship warranty or builder's risk coverage. This is contractual rather than statutory but attaches consequence to a specific individual.
Genuine two-tier structure: if laser screeds, ride-on trowels, and robotic finishers absorb the open-field slab work, the residual job is edges, curbs, columns, penetrations, decorative and repair work, and remediation of failed pours — the tier that resists mechanization. Watch fleet adoption rates for Somero and Ligchine screeds on commercial flatwork.
State or municipal adoption of a mandatory concrete finisher / flatwork license with personal sign-off on placement records — the model exists in Louisiana's contractor licensing and in ACI's certification tiers (ACI Flatwork Finisher/Technician). If a jurisdiction moved ACI Flatwork Finisher certification from a spec requirement into a code requirement, with the certified finisher named on the pour record for slab flatness/levelness (F-F/F-L per ASTM E1155) disputes, the shield rises materially.
Formalizing the finisher's authority to reject a truck or stop a pour on slump, air content, or temperature grounds — some union agreements and ACI 301 acceptance procedures already vest this call at the point of placement. If the reject decision is documented under the finisher's name rather than the superintendent's, the role owns a consequential, ambiguous, unrecoverable call.
Only in the decorative/architectural niche — stamped, polished, and exposed-aggregate finishes sold by named craftsman on a residential or hospitality job. This is a small fraction of the 206,170 and there is no route to a trust premium on structural or industrial flatwork, where the buyer sees a commodity slab.
The limit. Embodiment and task resistance are already near maximum, so there is little headroom there; realistic upside is roughly 8-12 points concentrated in licensure and named accountability. The binding constraint is not AI capability but wage pressure, crew size reduction from screed automation, and immigration/labor supply — none of which the register measures.

We have no reported case of a named organisation automating this occupation. Not one deployment, not one announcement.
That is worth saying out loud next to a score of 58. The verdict above is about what the work exposes — what current AI could do to these tasks. It is not a claim that anyone has done it. For this occupation those two things have come apart completely: the capability argument is on this page, and the evidence column is empty.
