Abstract: When baseline schedules are developed using preliminary design information, including but not limited to material quantities, sizes, and types, the baseline activity durations may be impacted once final design is completed. The preliminary-to-final design changes may result in an increase to the various material characteristics, which affect installation production rates, safety considerations, and methods of construction. These impacts may cause an increase in activity durations, which can result in project delays. This paper is written from a contractor’s perspective and will demonstrate how to quantify delay by impacting activity durations based on preliminary-to-final design changes. This procedure will be exemplified through a case study that was based on actual project experience. This delay quantification procedure can be used to substantiate change order requests and/or claims when design changes occur.
