Future of Visualization using Building Information Modeling (BIM) – 2020 Vision


With much hype about building information modeling (BIM) in last 5-6 years, now (2012) industry has arrived at a point where BIM is in every AECO professional’s dictionary. BIM is not only a fancy world in these professional’s dictionaries but they are using it for various advantages over their non-BIM using competitors. A recent example is the use of building information modeling at at Panama Canal Expansion.
It’s all good that BIM is in use and its adoption is increasing exponentially. The question posed to the industry geeks is what is the future of BIM? Well, here is my take on the future of BIM-

1. We will move from 2D display Views to 3D-non-immersive Viewing

User interfaces can improve task performance by exploiting the powerful human capabilities for spatial cognition. 3D displays support cognitive spatial abilities. Moving from 2D displays to 3D display will be the next main stream evolution of BIM.
 
2. We will further move from 3D-Non-imersive viewing to 3D-immersive viewing


At Harvard University, Mental Imagery and Human-Computer Interaction Lab investigates how distinct visualization abilities could be improved as a result of training in 3D immersive virtual environments. Their results demonstrate that 3D immersive environments appear to be significantly more efficient for training imagery skills than 2D or 3D non-immersive environments. Their findings revealed that the 3D Perspective-Taking Test facilitated a 200% increase in performance (i.e., the rate of error reduction), compared to the non-immersive 2D version of the test. 

3. We will use Augmented Reality for Visualizing Building Models

Yes, I am talking about spinning the building with your hands in an augmented reality world. If you may recall the Robert Downey Jr. (Iron Man in the movie) spinning iron man suite in the movie Iron Man, than you understand what I am talking about.


In the process of developing the product the engineer must mentally manage a large amount of important information which leads to high cognitive complexity. Available engineering drawings do not reduce the complexity that the engineer is facing or help him handle it. The 2D engineering drawings should be easy to use and should help the engineer manage the design-related complexity. The cognitive complexity can lead to a situation in which important design factors are not taken into consideration and this leads to failure. Realistic perception of the 3D models from 2D engineering drawings plays an important role in decision making of design engineers. Recent studies show that a system with a three dimensional representation of the model increases the performances of the users carrying out tasks which require the perception and understanding of spatial information. Unlike Virtual Reality (VR) systems, in which users are completely immersed in the virtual environment, Augmented Reality users see the virtual objects and the real world co-existing in the same space (co-located). The co-location of the 3D CAD models in the real environment provides the possibility of a realist perception of the physical engineering drawing.

Business Case for Building Information Modeling (BIM), Lean, Green and IPD - What we can learn from an Economist?

Vijay Govindarajan recently caught attention for his recent book "The Other Side of Innovation: Solving the Execution Challenge" published by Harvard Business Review and his work on "Designing $300 Home". He is called the strategic innovation Guru and he is also the Earl C. Daum 1924 Professor of International Business at Dartmouth’s Tuck School in US. He believes that perspiration is more important than innovation i.e. execution of an idea is more important than only coming up with the idea itself.

I will try to explain the advantages of BIM, Lean, Green and IPD by his theory of strategic inovation. He talks about three boxes that large organizations operate into (or where organizations' projects fall into)-








Building Lean and Green using BIM and IPD fall under Box-2 and Box-3 that is selectively forgetting the past practices and creating the future (and here we are talking about 20 years from now i.e. about 2030).
Hear is his talk with Harvard Business Review -…

World's Tallest Building Sky City-1 Changsha China and BIM, Lean and Green - What might be coming?

I feel fortunate to be living in an era when there are Computers, iPhones, iPads, Androids, Google Glasses, Google Earth, Facebook, Twitter and Broad Sustainable Construction. All but the last one out of my list are pretty obvious and I do not feel explaining why they are awesome. However, I feel like talking a lot about Broad Sustainable Construction, a company which is based out of China and doing miracle after miracle and revolutionizing what world calls development. As a matter of fact, China is doing great with several other things too. But this blog won’t be talking about that.

At this very moment (January 5th 2013) Broad Sustainable Construction is building world’s tallest building – Sky City –1, which is almost a kilometer high (838 m/2749 ft to be precise) with 220 floors. They are set to complete the construction of this building within 90 days. This is remarkable and revolutionary. They claim to prefabricate 95% of building off site. Guess what, whole world is trying to bri…

Data Driven Design and Construction - Answers to Randy's questions

Randy started a new blog that will focus on Data Driven Design and Construction. He asked few questions in his first post. Here is my take, feel free to comment. I recommend you should follow his blog. He will be coming up with a book on this topic next year some time. I can't wait to read it. Here are his questions and my answers - 
How do we, as a discipline, capitalize on data and metadata to drive innovation in architecture and construction, just as other disciplines and industries have?Evidence based design is one of the leading fields of research that will eventually result in data driven design and construction. Understanding the end user requirements better and designing products that reach to the highest level of customer satisfaction would require data driven design. On technology front, building information modelling (BIM), virtual reality and augmented reality will help collect the data related to customer requirement. Moreover, when construction is in progres…
