Abstract: 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.
