Abstract

Building information modeling (BIM) is a technology that should be integrated in the architecture, engineering, and construction industry because of its positive effects. BIM-based building condition assessment (BCA) is an emerging method that should be explored and practiced to obtain the benefits of BIM in building management and maintenance process. The purpose of this paper is to explore the BIM-based condition assessment method by conducting a survey on the water ponding defect on a flat roof. The survey was conducted by a visual inspection and pictorial. A written report was produced after the survey. A 3D BIM model was generated by using Revit Architecture. This model was then integrated with Tekla BIMsight to produce a 4D model that consists of a 3D building view and building information. General building inspection was conducted to determine the existing condition of the flat roof and any possibility of the water ponding defect. Results show that water ponding occurs on flat roof areas during and after heavy rainfall because water does not efficiently flow through the rainwater downpipes (RWDPs). This obstruction in water flow is caused by the presence of dirt and the insufficient number of RWDPs in certain areas. Furthermore, BIM-based BCA shows a positive effect by providing a 4D model that is easy to understand, access, and store by the building management team.
