## What this work is

**Core tasks** (O*NET):
- Inspect wiring connections, control panel hookups, door installations, and alignments and clearances of cars and hoistways to ensure that equipment will operate properly.
- Assemble, install, repair, and maintain elevators, escalators, moving sidewalks, and dumbwaiters, using hand and power tools, and testing devices such as test lamps, ammeters, and voltmeters.
- Disassemble defective units, and repair or replace parts such as locks, gears, cables, and electric wiring.
- Check that safety regulations and building codes are met, and complete service reports verifying conformance to standards.
- Assemble elevator cars, installing each car's platform, walls, and doors.
- Locate malfunctions in brakes, motors, switches, and signal and control systems, using test equipment.
- Bolt or weld steel rails to the walls of shafts to guide elevators, working from scaffolding or platforms.
- Adjust safety controls, counterweights, door mechanisms, and components such as valves, ratchets, seals, and brake linings.
- Read and interpret blueprints to determine the layout of system components, frameworks, and foundations, and to select installation equipment.
- Connect car frames to counterweights, using steel cables.
- Connect electrical wiring to control panels and electric motors.
- Maintain log books that detail all repairs and checks performed.

## AI exposure & outlook

- **AI task-overlap index:** 18th percentile (Low) across all occupations — composite of current-era exposure studies (ai-exposure-index-v1).
- **Overall AI exposure (Felten et al.):** 23rd percentile (Low) — source: felten_aioe.
- **LLM task exposure, γ (OpenAI / Eloundou):** 25th percentile (Low) — source: eloundou_gamma.
- **AI assistant applicability (Microsoft):** 14th percentile (Low) — source: microsoft_applicability.
- **Frey–Osborne (2013, historical computerization estimate):** 43rd percentile — kept separate from current-era studies.
- **Remote-capable (Dingel–Neiman):** no — task structure, not who actually works remote.
- **Projected employment (BLS 2024–34):** 5.0% growth (About average); 2k annual openings; 24.2k → 25.4k jobs.
- **Pay & employment (BLS OEWS, May 2024):** median $106,580; 23,340 employed.
