Some of the major benefits of BIM over traditional design approach

Before I begin with the benefits of Building Information Modeling which is abbreviated as BIM, let me state it right away that substantial amount of changes have taken place in the design development process over the last few decades.  Technical 2D drawings which were largely developed manually through paper and pencil, were used as major deign information tools by architects and engineers in the ancient time. Design and construction professionals used to develop hundreds of technical drawings which used to be circulated by them to different AEC professionals before they could really start the process. And developing technical drawings manually is really a back-breaking or exhausting task.

Traditionally there was no other way of representing design information apart from technical drawings, and because of that, identifying errors in design was also a very hectic job. But a few decades back software manufacturing company Autodesk came up with a design and drafting software AutoCAD which largely changed the fundamentals of design development process. The manual technical drawings were then replaced by digital drawings, which largely saved drafters, architects and engineers from implementing too much efforts and hard work during their development.

Apart from digital drawings CAD also introduced 3D model-based design approach which if compared to 2D drafting services is seriously beneficial for architects and engineers. But the model-based design strategy brought by Building Information Modeling is highly advanced compared to CAD based design approach. CAD models can be explained as the extensions and elaboration of 2D drawings since they provide limited or restricted information about the construction project in question. Whereas parametric BIM models which are developed in much advanced building design solution Revit, impart immensely substantial information on design of the building, its cost, completion time, materials required and bill of materials etc. This immensely substantial information can be utilized by AEC professionals for many reasons.   For example, they can minimize the cost of the project by trying to reduce material wastage and this can be achieved with the optimization of material takeoffs, which can be used for controlling the purchase of extra materials. In this manner BIM can be utilized by contractors and owners for curtailing time and money required for project execution.
