What this score means

Most of this role's work is still genuinely hard for AI to do. Physical presence, bodily skill, high-context judgment, direct human care - the things that don't translate to text.

If you're in this role, here's what to do now

You're not in the firing line today. But the frontier moves. Build enough AI fluency now that you can direct it for the parts of your work that could benefit. People in unexposed roles who understand AI become unusually valuable inside their organisations.

Where a project with Alex usually starts for this role

This role's strict reading is low because its top tasks are judgment, not drafting. The three highest-stakes tasks below are still usually where we start — flip the toggle to 'With tools' to see what AI plus the right context can compress.

  1. Read blueprints or other specifications to determine methods of installation, work procedures, or material or tool requirements.

    O*NET importance 4.2/5 · still needs a human under the strict reading

  2. Measure and mark surfaces to lay out work, according to blueprints or drawings, using tape measures, straightedges or squares, and marking devices.

Most roles have at least three wedges where AI plus the right tools removes real time. For this role the labelling doesn't surface obvious ones, so we'd start with the highest-stakes tasks below and figure out the AI angle in conversation.

  1. Read blueprints or other specifications to determine methods of installation, work procedures, or material or tool requirements.

Methodology

This role's exposure score comes from Eloundou et al's 2023 GPT task labels, aggregated by O*NET importance within each O*NET-SOC code, then bridged to UK SOC 2020 via ISCO-08 (ONS Vol 2 coding index) and US SOC 2010 (BLS crosswalk). Employment and median pay come from ONS ASHE Table 14.7a, 2025 provisional. ASHE covers employees only, so self-employed workers are not counted.
