Creation of Formula to Predict Time and Cost Benefit by Using 5D BIM Rather than Traditional Method of Construction

Abstract

Building Information Modeling (BIM) is becoming a well-known established collaboration process in the construction industry. Owners are increasingly requiring BIM services from construction managers, architects and engineering firms. Many international construction firms are now investing in “BIM” technologies during bidding, preconstruction, construction and post construction. The goal of this research is to understand and examine the uses and benefits of 5D BIM for construction project of Pakistan. There are three objectives to this research. First is to make comparative analysis of an existing high rise building with reference to scheduling and cost as done by traditional method. Second is to develop 5D model of high rise building with help of autodesk revit and autodesk navisworks. Third is to make 3D models of 20 and 30 storey building on autodesk revit and navisworks by making 10 storey building as reference to overview the comparative benefits of schedule and cost with help of 5D BIM and development of formula with reference to schedule and cost for any number of stories of building. First an existing commercial building was selected for comparative study between 5D BIM analysis and traditional CAD methods. 5D Building information model was created and analyzed. Furthermore, the BIM-based schedule and cost was integrated to 5D model. Finally, the project concluded with an analysis on the advantages of 5D BIM and its implementation barriers in construction industry of Pakistan. The study concludes that despite of few shortcomings and barriers in 5D BIM implementation, BIM and 5D construction processes are concluded as a promising tool for construction planning. 5D BIM modeling helps to reduce time and cost of a project and provide efficient planning by better visualization of construction work, better communication among project teams, detailed and accurate work plans and quantity takeoffs. Also, with increase in number of stories time and cost benefits also increase in 5D BIM.
