BIM – A Process Or Technique That Changed The Shape Of Construction Industry

A few decades back there was a time when building stakeholders such as owners, contractors, architects, engineers and fabricators etc., had to suffer a lot from the pressure of budget overruns. That means the final cost of the construction project used to exceed the  cost which used to be calculated by building stakeholders for the project in question during the pre-construction phase.  Now what are the reasons behind that? What sort of problems were faced by architects and engineers due to which they used to end up developing a building in a much higher cost.

Well, the fact is that there were several reasons which used to be accountable for increasing amount of budget overruns in the past. The first and most important among them was the poor use of technology and design documentation tools during the execution of the project. And because of the poor use of technology and design documentation tools, architects, engineers, drafters and detailers used to be largely unsuccessful when it comes to generating precise or error-free building design. Now, that used to be ultimately responsible for large-scale rework which used to be performed by building professionals on the actual location of the project. And it is quite understandable that rework remains the major factor behind enhancing project cost.

Since there is no dispute on the fact that ‘necessity is the mother of all inventions’  slowly and gradually construction experts also came up with reliable tools and techniques, which could simplify their work largely. And that is how they came up with the concept of Building Information Modeling Services, which has become tremendously popular in the last one decade because it provides them with amazing results. BIM is a process of generating 3D, 4D, 5D and 6D Building Information Models, which contain detailed information on design, time, cost, schedules, and material takeoffs etc. These models are created with the help of advanced BIM software like Revit and ArchiCAD etc. Apart from helping architects and engineers in generating high-quality building design, BIM software products are also crucial for generating material takeoffs and Bill of materials which are eventually utilised for identifying right project cost. In addition to that project information available in BIM models can also be optimised for identifying the real world challenges of final construction. And all of this finally supports in bringing more efficiency during actual construction, which ultimately helps in reducing project.
