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. Keywords: BIM, Construction Planning, Construction Technique, 4D, 5D Modeling
Highlights
In, India many organizations which are involved in public sector or procurement area the designer and contractors needed an advance technology for fastest progress of work in construction area which is an essential tool for developing any country
Since the implementation of BIM is increasing in Indian Construction Industry with each passing year, it can solve these types of issues very efficiently
Nagpur Metro station project is based on digital project management policy which is integrated with SAP i.e., including the live project recording to a virtual model during entire project lifecycle which converts old transport system into new transport system and uplift the BIM level in Asian countries4,5. 5D BIM technique helps the project manager to create different models to show how the changes involved in metro design work, construction material and layout which can increase the quality of project delivery
Summary
India many organizations which are involved in public sector or procurement area the designer and contractors needed an advance technology for fastest progress of work in construction area which is an essential tool for developing any country. 5D BIM technique helps the project manager to create different models to show how the changes involved in metro design work, construction material and layout which can increase the quality of project delivery. It is a multi dimensional action of activities which analyzes project feasibility. The flowchart of overall progress of work includes research discovery, questions, objectives, methodologies and three stages of projects with their description under which online survey, formulation of 3D model in different software and 4D and 5D BIM applications are shown in (Figure 3). The overall information provided by application model describing their links with multi model and with collaboration processes[16]
