Abstract
AbstractProper scheduling is essential for timely completion of a construction project. Inaccurate estimate of duration leads to project delays. Currently, critical path method (CPM) is widely used for project scheduling. However, CPM leads to ineffective scheduling due to over estimation of durations. Past studies especially from manufacturing sector revealed that critical chain project management (CCPM) is potential technique for accurate scheduling of any project. CCPM utilizes different buffers—resource, feeding and project to estimate the accurate duration. Buffers help to estimate realistic activity duration. Therefore, objective of the study is to develop a framework for scheduling projects using CCPM. The framework aids in estimating different buffer sizes. A residential building project case study was chosen to implement the proposed framework. The analysis indicated that no optimum resource buffer can be found for all construction projects. Each project is unique and can have different resource consumptions and performances. Further, findings revealed resource buffers can aid to minimize the duration of construction projects.KeywordsBuffer sizingCritical chain project managementCritical pathFever chartsStimulation
