Detection of schedule delay risk of empirical construction projects

Tsegay GEBREHIWET, Hanbin LUO

Frontiers of Engineering Management 2018, Volume 5, Issue 2,   Pages 251-267 doi: 10.15302/J-FEM-2018086

Abstract: In Ethiopian construction projects, schedule delay risk is a predominant issue because it is not properlyefforts have been made to investigate the typical and the overall schedule delay risk.In this study, our aim is to detect the typical and overall schedule delay risk throughout the constructionThe findings showed that there is a typical delay risk either in the type or in the level of the differentthe exact risk level on specific activity to make appropriate decision.
