EXPOSED
Cutting, bending, placing and tying rebar per engineered drawings is heavy, dirty, outdoor work on uneven decks and in footings — language AI cannot touch it, and general-purpose robots are nowhere near it. The real pressure is mechanization inside the trade: shop-prefabricated rebar cages, CNC bending lines, and rebar-tying robots like TyBot on flat bridge decks and slabs eat the most repetitive hours. No license shields the job and the engineer, not the placer, signs the drawings, so protection comes almost entirely from the body and the jobsite.
Tasks largely resist digitisation. Wiring #8 bar into a column cage at height, walking mats on a mud footing, and hand-bending hooks to fit a congested beam-column joint are motion problems no model solves — the 17 rather than 20 reflects that flat-slab and bridge-deck tying, plus shop cutting and bending lists, are already being done by CNC lines and gantry-mounted tying robots.
Hands-on in uncontrolled environments. You carry and place bar in trenches, on suspended decks and in rain, kneeling on grade all shift with tying tools and cutters, at genuine risk of impalement and struck-by injury — an 18 rather than 20 only because prefabricated cages set by crane shift a slice of the work into a controlled shop.
No licence, no signature requirement. No state license or certification is required to place rebar; OSHA 1926.701 impalement rules and the inspector's checklist bind the contractor, and the EOR's stamp on the placing drawings carries the design liability, leaving you with the 4 points that come from being the person the inspector watches tie the lap splice.
Anonymous artifact production. Your work is buried in concrete within days and no one who pays for the building knows your name; the 5 comes from foremen and superintendents rehiring specific rodbusters who can read a bar list and keep pace with the pour schedule, which is crew reputation, not client relationship.
Meaningful discretion. Bar sizes, spacing, lap lengths and cover are all dimensioned on the placing drawings, so the 7 covers the real calls you make in the field — how to sequence congested mats, where to add ties and chairs so the cage doesn't shift under the pour, and when a conflict on the drawing has to go back to the engineer rather than be fudged.
