  "reasoning": {
    "task_resistance": "Fitting a 40-foot girder means shimming, wedging, and re-clamping until the flange sits within tolerance on a plate that has already pulled from heat — that hands-on reconciliation of drawing to warped steel keeps this at 14, while nesting, cut lists, and beam-line drilling programs are genuinely already machine work, which is what stops it from scoring higher.",
    "embodiment": "Overhead cranes, chain falls, grinders, and hot tack passes on stock that shifts as it cools puts this at 17: the shop floor is enclosed and lit, unlike ironworkers erecting steel in weather, but nothing about positioning a 2-ton assembly on horses happens from a console.",
    "liability_shield": "AWS D1.1 procedure qualification and employer weld tests gate who touches the joint, but the certification travels with the weld procedure and the PE stamp on the structure belongs to the engineer of record — a fitter faces no personal licensure exposure, hence 4 rather than 10.",
    "trust_premium": "Fabrication is bought by drawing number, bid price, and delivery date; a general contractor swaps shops between jobs without noticing who ran the layout table, so the 3 reflects reputation attaching to the shop rather than to you.",
    "judgment_accountability": "Deciding tack sequence and weld order to control distortion, or calling a fit-up bad and sending a member back to the cutting table, is real discretion that costs money if wrong — but tolerances, WPS parameters, and inspection hold points are written down and a QC inspector signs off, which caps this at 9."
  },
  "rationale": "Laying out, aligning, clamping, and tack-welding heavy plate and beams is physical work in a shop where parts warp, fit-up gaps vary, and nothing lands exactly where the drawing says — language AI does nothing about that. The real pressure is not chatbots but capital: CNC plasma tables, automated beam lines, and robotic weld cells already absorb the repeatable cutting, drilling, and long-run welding, which is why headcount concentrates in custom and low-volume work. Blueprint interpretation and cut-list/nesting math are the parts AI and CAM software eat first; there is no license protecting the trade, only AWS certifications and employer qualification tests.",
  "outlook": "The work persists in custom, heavy, and field fabrication, but shops keep shifting repeatable cutting and welding to automated cells, so the occupation slowly shrinks toward fit-up specialists and certified inspectors.",

FHWA fracture-critical bridge member fabrication rules already come close to this.",

As shops finish automating the repeatable tier, remaining measured task mix shifts toward the judgment/hand-fit tier without any law changing.",

        "change": "If prefab/modular construction growth pushes more field tolerance decisions upstream into the shop — fabricator deciding whether an out-of-tolerance member is shimmed, reworked, or rejected before it ships, with rework cost and schedule liability landing on the fab shop under design-assist or delegated-connection-design contracts (already common in AISC delegated connection design practice) — the fitter's calls become consequential and documented.",

    "ceiling_note": "Trust premium has no plausible route: structural steel buyers are GCs and EPCs buying to spec and price, and no end customer pays for hand-fit steel as such. The binding threat here is capital equipment, not language models, so institutional levers move the score more than any AI plateau does."
