Assemble mechanical, electrical, and electronic components into models or prototypes, using hand tools, power tools, and fabricating machines.

“Assemble mechanical, electrical, and electronic components into models or prototypes, using hand tools, power tools, and fabricating machines.” is a core task performed by Model Makers, Metal and Plastic. Among the occupation's 16 rated tasks, workers place it 2nd by importance (#15 most important). About 44% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

Work activities this task rolls up to

O*NET groups concrete tasks into broader work activities shared across many occupations.

• Assemble products or work aids. in Handling and Moving Objects

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E0. No direct exposure — current language models give little or no time savings on this task.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.00. Automation potential label: T0.
