What is the difference between CAD and architectural BIM services?

For decades, engineers, planners, and architects have relied on CAD services to generate detailed 2D drawings of the projects. Now with the arrival of Building Information Modeling (BIM) into the picture, the question that arises is are these two things the same? The negative answer to the above question further raises the question “what is the difference between CAD and architectural BIM services?” This central question will be delved upon in the course of the following pages.

Before talking about the differences between CAD and architectural BIM services, let’s first figure out the scope of CAD. CAD is an acronym for computer-aided design and refers to the documentation and design process executed through the help of computer technology. The 2D drawings of parts and assemblies produced using CAD can be used for manufacturing the component. 

Realizing the immense benefits offered by CAD including reduced time-to-market as compared to hand drawings, there has been wide-scale adoption of CAD over the past two decades. The applications of CAD have ranged from industries to construction projects and everything in between. Now that we have talked about CAD, let’s talk about BIM in brief before we can focus on the differences between the two.  

BIM is defined as a methodology and process through which a team of engineers, contractors, architects, and other stakeholders can work collaboratively on the same platform. The BIM helps the stakeholders design a coordinated and clash-free 3D model of the project by working on the same model and database. By working on the same model the team can analyze and visualize the design designs long before the first brick has been laid. 

BIM helps in creating a digital representation of the building and its systems. While doing so it acts as a shared resource that helps multiple stakeholders to collaborate in the project execution. Thus, architectural BIM services offer a marriage between technology and process and create a single channel of communication to ensure smooth and efficient project execution. 

The central 3D model created by BIM, not only makes the process more time and cost-efficient but also significantly reduces error in the construction phase. BIM helps in the easy identification of clashes in the design phase which can then be resolved before construction begins. Further, BIM can provide detailed material requirement sheets for construction projects- helping in their timely completion. 

So, if we compare BIM with CAD, then the difference is quite obvious. As compared to CAD which has applications in multiple engineering disciplines, BIM is specifically created for construction projects. In the domain of construction projects, BIM can beat CAD hands down for the immense benefits that it provides. Thus, it is best for the AEC industry players to adopt BIM at the earliest and unleash a plethora of benefits.
