Historical Labor Productivity Estimate Agent

Labor is the riskiest part of an estimate, and draft hours are often based on gut feel. This agent pulls the firm's past job cost data and calculates actual productivity rates, such as hours per square foot or per unit, adjusted for crew, height, weather and project type. Jobs with major disruptions are excluded. It checks that at least 3 similar jobs back each rate; if not, it widens the job types or marks the rate low confidence. It applies the rates to the new takeoff and compares the result with the estimator's draft. Gaps over 15% are explained with the jobs behind them. The estimator decides the final hours. Edge case: a job that suffered a long strike or redesign is left out so it does not inflate the rate.
