Tim Fairley's construction channel treats AI as a workflow question. He has published more than 95 Claude skills, and the July 2026 video estimators forward to each other is I've Built 95 Claude Skills for Construction — Here Are the 8 Best.
Each skill is written the same way: inputs, a transformation, and a fixed output that is a spreadsheet, a checklist, or a register. The computer goes onto the unread pages, and the price and the method stay with a person.
Counting tagged fixtures on a vector PDF can work. Measuring areas and lengths usually does not.
That is Fairley's own limit on takeoff, the skill estimators ask for first. Counting fixtures puts every checked sheet on a coverage list, and the measure still belongs to a person. Auto Gantt is off his list on the same logic: a 20-year supervisor beats the model on build method.
A GC mapped those eight skills onto a live Procore app in August 2026. Drawing compare, sub-proposal check, and asking for the unknowns before a ROM were already built. A bid requirements register was not, and it went on the board. Cash-flow forecast and contract-notice calendars stayed further down the list.
Josh Turner, a civil project manager in New Zealand, teaches the same habit on a smaller channel: pick one workflow, write down the inputs and the human role, then install it as a skill. Ask a model to make a risk register and a generic one comes back.
