Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on
Moving bricks, blocks and mortar
Lifting and moving heavy units and mortar around the site and up to the working level.
Being augmented≈ Platform inference
Where this applies
Denmark. A crossover field study of eighteen masons bricklaying with and without a back-support exoskeleton found increased muscular strain in the low back (5.2 percent) during exoskeleton use; usability was rated positively but acceptance was low because of discomfort and workflow interference, and only 22 percent were willing to use it in future. One device and a small sample; it measures strain, not productivity or employment.
What this means
Wearable lifting aids have not yet made bricklaying lighter on the back.
What it does not yet show
One device in one small study.
What you can check
Open PubMed record 41819654 and find "Only 22% of participants".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
