Rolling Fours: Novel Work Schedule

Rolling fours is a work scheduling scheme that will shorten the duration of the construction phase of a project by approximately 30–45%. It calls for working every calendar day, but avoids personnel fatigue by cycling two different groups of employees every four days. The history, application, terminology, work‐hours, scheduling, wage and salary rates, and pertinent statutes related to rolling fours are discussed. Organization and management of an actual project are presented. Actual progress employing two ten‐hour shifts per day under a rolling fours schedule is compared to the originally planned two ten‐hour shifts, five days per week schedule. 46% more work was performed using rolling fours than would have been performed under the original schedule.
