ABSTRACT
Example. If it takes one worker 1.25 hours to perform a task normally performed by another worker in 1.0 hour, the productivity factor is 1.2Y1.0 = 1.25. This factor is influenced primarily by methods of construction, working skills, use of labor-saving tools and equipment, climate, communication barriers, and social habits. This is a very subjective factor and we often rely on experience and relationships to other known locations to estimate productivity factors for new locations.
