摘要

Labor has an undeniable effect on a construction project and represents a major source of risk for the contractor. Better (or worse) than expected productivity certainly causes a positive (or negative) impact on the global schedule and cost, and thus must be properly monitored and controlled. Measuring the efficiency of direct manpower is a task ordinarily carried out by many contractors, but keeping records of quantities of work performed and the corresponding man hours is not enough. Some questions remain: (i) what is the overall efficiency of the manpower? (ii) what is its impact on the project as a whole? (iii) what is the trend of the labor production rates, and how does it affect the originally estimated scenario? (iv) what actions must be taken to bring the job to the desired standards? In this paper the authors present a methodology for measuring and interpreting productivity and forecasting future behaviour by means of Earned Value Analysis.
