EXPOSED
This is a catch-all bucket — segmental paving crews, tank/septic servicers, weatherization and specialty trade helpers, general 'all other' construction roles — and the modal worker spends the day on a job site placing, cutting, fitting, digging, and hauling in weather and dirt, which no shipping robot does. Language AI touches almost none of the core work; the exposure is in the thin paperwork layer (permits, daily logs, material takeoffs, scheduling) and in AI-assisted planning that trims crew hours. The reason the score isn't in electrician territory is credential thinness: most of these titles carry no state license, no stamped sign-off, and no named client relationship, so wages and bargaining power rest on labor supply rather than a legal moat.
Tasks largely resist digitisation. Setting segmental pavers to grade by hand, pumping and hosing out septic tanks, blowing cellulose into knee-wall cavities, and hand-digging around live utility laterals are tasks where the variability of the substrate — soil, existing structure, unmarked pipe — defeats fixed-path machinery, which is why this sits at 18 rather than in the 14 range where more repetitive prefab or panel work would land.
Hands-on in uncontrolled environments. A 19 reflects excavation, confined-space tank entry, roof and crawlspace access, respirators for insulation dust, and lifting pavers or block all day in whatever weather the schedule hands you — the only thing keeping it off 20 is the fraction of these titles that includes some shop or staging work.
Certification preferred, not legally required. Most of these titles hire off a résumé and an OSHA 10 card; septic servicers may need a state pumper registration and confined-space or lead-RRP certification, but nobody stamps a drawing and nobody's personal license is on the line when the work fails — the GC's or the licensed sub's is, which is why 5 and not 11.
Some relationship component. A 10 recognizes that repeat septic and weatherization work builds a homeowner-level relationship and that GCs re-call crews they trust to show up and not damage the site, but the customer signs with the company, not you, and the next job comes from the dispatcher.
Meaningful discretion. An 11 covers the real calls made without a supervisor present — stopping the shovel when you hit an unmarked line, deciding a base isn't compacted enough to set on, judging whether a tank lid is safe to stand on — while acknowledging that grades, specs, and sequencing come down from someone else.
