Comparing three scheduling methods using BIM models in the Last Planner System

This article presents strategies for teaching scheduling methods such as takt-time, flowlines, and point-to-point precedence relations (PTPPRs) using build­ing information modeling (BIM) models in the Last Planner System. This article is the extended version of the article entitled “Teaching Takt-Time, Flowline and Point-to-point Precedence Relations: A Peruvian Case Study,” which has been published in Procedia Engineering (Vol. 196, 2017, pages 666-673). A case study is conducted in final year students of civil engineering at the Pontifical Catholic University of Peru. The mock-up project is an educational building that has high repetitive processes in the struc­tural works phase. First, traditional tools such as Excel spreadsheets and 2D drawings were used to teach produc­tion system design with takt-time, flowlines, and PTPPR. Second, 3D and 4D models with Revit 2016 and Navis­works 2016 were used to integrate the previous schedules with a BIM model and to identify its strengths and weak­nesses. Finally, Vico Office was used for the automation of schedules and comparison of the methods in 4D and 5D. This article describes the lectures, workshops, and simu­lations employed, as well as the feedback from students and researchers. The success of the teaching strategy is reflected in the survey responses from students and the final perceptions of the construction management tools presented.
