Estimate maintenance service requirements or costs.

Estimate maintenance service requirements or costs. is a detailed work activity in O*NET — a concrete unit of work shared across 4 occupations and seen in 5 occupation-specific tasks. It rolls up into the broader work activity Estimate project development or operational costs. in Estimating the Quantifiable Characteristics of Products, Events, or Information .

Detailed work activities are the most granular shared layer in O*NET's work-activity hierarchy (Generalized → Intermediate → Detailed → occupation-specific task). The figures below describe how this activity shows up across the economy and what independent studies measure about AI and this kind of work — not a prediction that the work will be automated.

AI exposure

Of the 5 tasks under this activity that the OpenAI / Eloundou “GPTs are GPTs” study rated, 5 (100%) are flagged as directly exposed to language models (E1) or exposed via model-powered tools (E2).

Exposure estimates overlap with model capabilities — whether a model could speed the task up — not whether the work will be done by software. Observed AI use is augmentation and assistance today, not jobs replaced.

Member tasks

Occupation-specific tasks O*NET maps to this detailed work activity, most important first.

• Plan and develop budgets for tree work, and estimate the monetary value of trees. · Tree Trimmers and Pruners · importance 4.1 · exposure with tools
• Perform financial tasks, such as estimating costs and preparing and managing budgets. · First-Line Supervisors of Housekeeping and Janitorial Workers · importance 4.0 · exposure with tools
• Prepare service estimates based on labor, material, and machine costs and maintain budgets for individual projects. · First-Line Supervisors of Landscaping, Lawn Service, and Groundskeeping Workers · importance 3.9 · exposure with tools
• Measure area dimensions requiring treatment, calculate fumigant requirements, and estimate cost for service. · Pest Control Workers · importance 3.7 · direct LLM exposure
• Design or supervise the installation of sprinkler systems, calculating water pressure, or valve and pipe coverage needs. · First-Line Supervisors of Landscaping, Lawn Service, and Groundskeeping Workers · importance 3.4 · exposure with tools
