4D Schedule Optimization for Project Monitoring of Existing Educational Building

Project management is an important domain, especially in the allocation of resources and smooth operation with an assigned budget. To successfully complete a project, it is important to follow effective ways to use available tools, technique, and methods, considering present technology and management. Recently, Building Information Modelling is one of the techniques which creates, manage, or generate a model by taking physical and functional characteristics of building by using digital presentations. Term 4D modeling refers to fourth dimension that associates the 3D model of any construction project with the planned schedule and provides visualization of the actual sequence of construction activities. The study was carried out to understand the uses and benefits of BIM for better proper functioning of the project in accordance with the project schedule. The objective of the study is to minimise the challenge associated with traditional or conventional scheduling process of construction sequences and misunderstanding brought by the lack of visualization. To fulfill the objective of the study, the uses of different dimensions of Building Information Modelling (2D, 3D and 4D) for preconstruction and construction phase was identified. Then a prototype 4D Building Information Model was created and the BIM based schedule was integrated with it and studied. The software used for scheduling, 3D modelling and 4D simulation are Primavera, Autodesk Revit, and Autodesk Navisworks respectively.
