Abstract

Background/Objectives: To conduct online survey on Indian BIM organizations. Secondly, results of 4D and 5D BIM applications are to be evaluated and compared between 5D BIM technique and traditional technique. Methods/ Statistical analysis: The methodology adopted in this research is based on BIM software. For 4D analysis, software like Navisworks Freedom and Navisworks simulation are used. The data collected from MSP file forming a Gantt chart which is further exported into Navisworks for time evaluation. In case of 5D, BIM Revit software is used for calculating cost and then comparison is made between Sigma estimate and traditional cost estimate technique. Findings: This research concludes that 4D and 5D modeling techniques play an important role in designing work of any construction project. It helps the owner or designer for gaining accurate work progress, planning a short-term arrangement in less time, construction planning and to develop high economy at low scale for small level projects. This study evaluates the difference in time and cost taken by traditional construction techniques of residential house building and 4D and 5D BIM techniques. Traditional techniques require more time than BIM technique because it reduces time up to 80% for the same project. The cost of project by using 5D BIM technique decreases 20-30% after comparing with traditional technique which helps the Indian construction projects to maintain overall budget of project and increased economy. Improvements/Applications: BIM serves several applications which include: Better cost scheduling, recognition of time based clashes, estimation of cost during whole project lifecycle, clash detection and MEP BIM coordination etc.
