How does BIM assist in Architectural modeling?

Architectural modeling has become a very crucial part in the execution of architectural projects. One can hardly observe any construction process taking place without first executing modeling services for it. If in case the final construction process starts  for a certain project without generating a 3D model for it, chances of facing errors and complications are very high.  Not just that, when the errors occur rework takes place and this helps in  increasing the overall project cost along with increasing the time taken to complete a project. So it’s a total loss for the contractors and the owners as well if they start constructing a building without making its model first.

The application of BIM has many advantages for the architectural, engineering and the construction industry.

Architectural modeling services are executed with the assistance of BIM software Revit.
To execute the modeling services for the architectural projects it is significant to have all the necessary input in place. So the process of modeling cannot go ahead until and unless the accurate and precise CAD drawings are developed. And the CAD drawings cannot be generated without the specification provided by the architects. So the process begins with the rough sketches and specification by the architects which are then given to the CAD technicians to come up with the architectural drafting documents. These specifications are reviewed by the CAD drafters various times until and unless a proper understanding is gained by them regarding the architectural design of the building.

After completely understanding the design the CAD drafters develop the architectural drawings. The drawings which are generated in the drafting process include floor plans, elevations and sections, etc. and they give the detailed description of the building design.

When all the required inputs are generated for the modeling process it is handed over to the BIM modelers and they develop 3D architectural model with the assistance of Revit. This 3D architectural model can be further upgraded to 4D, 5D and 6D with the addition of new dimensions in it. The more the dimensions are added to the 3D BIM model the more information rich it becomes.

The 4D and 5D architectural BIM  models help in estimating the time and money needed to complete the project. This ultimately makes the entire process proceed smoothly.
