Lessons Learned from Schedule Estimation Using Real-Time Data in a Concreting Operation

摘要: The unique, complex and interdependent nature of modern construction operations means that the use previous datasets in simulating a new project may raise validity issues. To address this problem, real-time data simulation studies has been introduced practiced recent years. However, little is known about details how to better estimate performance an operation. In particular, there awareness timing collection required yield valid sample on which base subsequent plans schedules for entire Using from concreting operation Dubai project, paper examines reliability forecasted results using different segments available data. For purpose, are statistically analyzed then segmented based percentage completed. A discrete event model developed schedule each cumulative segment compared actual Through case study, it was found statistical distribution identified at early stage not successfully represent properties whole dataset due local extreme variation; important identify bottleneck resource (e.g., pumps study) pay particular attention variation its cycle time order control
