Analysis of Benefits, Advantages and Challenges of Building Information Modelling in Construction Industry
Building Information Modelling (BIM) has become a well known established extensive collaborative process and an important area of development in the Architecture, Engineering and Construction (AEC) industry and has transcended all disciplines. The use of BIM in construction projects can possibly increase the information quality needed for making critical design decisions to access a building's environmental impact. Analysis, design and infrastructure of buildings are formulated with the help of samples generated from BIM. In the last decade, BIM has witnessed an increasing development. This was a result of their rapid capabilities applicable to construction projects. BIM can generate a common language for all divisions of parties and systems in a project and make them a combined team. The BIM method is strongly matched with delivery systems for integrated projects. Harnessing the unrealized possibility of the full life cycle use of the model by integrating it with the amenities and property management phases of buildings and infrastructure is one of the advantages of BIM which makes it suitable to the industry. This analysis is intended to show the correspondence of BIM and project manager's roles on construction projects. It insists on the significance of proper knowledge and experience of project managers to get succeeded in BIM. Initially, this review presents an in depth analysis of present literature frameworks and surrounding methodologies to assess and examine the BIM advantages and static design. Then 3D, 4D BIM and BIM based scheduling techniques are examined. The use of the term 4D to refer to the fourth dimension time is also discussed. i.e. 4D is 3D schedule (time) The role of 4D BIM is to add a novel dimension to 3D CAD or solid modelling. The paper also reviews the issues regarding the BIM implementation, static design and intrinsic problems related with an attempt to assess the advantages in a purely quantitative fashion. Through the application of BIM technology for the dynamic querying and statistical investigation of construction schedules, engineering, resources and costs are the three implementations considered to be proved as how BIM can ease the extensive grasp of a project's implementation and progress. Recognition, conflict solving, contradictions between construction resources and control costs, decreasing project over spends and protecting the resource supply are also dealt with. A BIM overview with specifications on its core and cycle concepts, benefits of the project life with the help of surveys has been discussed. The paper also elaborates risks and obstacles in BIM implementation and future BIM trends.
