The Commercial Real Estate Revolution

I recently facilitated a BIM Webcast for Reed Construction Data. 2500 signed up and 1019 participated, 3x more than anticipated. We also fielded more than 250 questions after the Webcast. That means there is strong interest in the topic.

You can still view and listen to the webcast and review answers to questions by going to WEBCAST. I’m offering a free copy of our the BIM chapter from our book. You can submit your request at the end of this blog.

One of the statistics shared during the Webcast is that BIM use has reached 50%. It is an accurate number if counting the number of architectural firms who have bought BIM software. However, this is where the mirage comes in.

My take is by no means scientific but I have probably visited close to 100 firms in the last two plus years and I always probe how firms are using BIM. Here is what I hear.

Most use BIM for visualization and some for clash detection. The clash detection is again a derivative of the visualization. Both of these applications only require “dumb objects.” A dumb object is a door, a run of ductwork or any part of a building that includes the geometric information but none of the objects properties or rules for how it behaves in relation to other objects. In other words these have the “M” or modeling part of BIM but none of the “I” part that provides analytics.

What are analytics? They can be anything. For example, analytics can contain the data and rules to provide the weight and compression for a section of concrete showing the required tension for reinforcement. One can then model the required balance between rebar and concrete. This not only allows one to make sure there is adequate reinforcement (safety issue) but also not too much (cost issue). A Dallas architect who is the real deal when it comes to BIM use was able to reduce the original concrete spec for a project by $300,000 through BIM modeling and analytics.

The most common use of analytics is clash detection. When objects have data that tell the object where it is in space and what is next to it can tell if someone is trying to design another object that will interfere; like plumbing through ductwork. But I seldom hear that use. Most of the clash detection I hear about from firms is the old fashion visual scan of a plan. I’d rather have the model tell me that I messed up than counting on catching it 100% of the time solely by human review.

There are several deeper levels of BIM use that distinguish the novices and wannabees from what I call the BIM Savants. If you think you are a BIM Savant let me know who you are and why you think you’re the real deal. When I go out to speak I try to recognize those I consider the real deal.

I’m asked less frequently if I think BIM will catch on – its been caught and rapidly growing. However, with the rapid adoption of BIM comes a side effect. Similar to what has been happening to the Green bandwagon. We now have a lot of BIMwashing. Half of the architectural firms are now out telling their clients that they “do BIM” when less than 10% are fully using analytics. Owner’s can’t tell the difference.

So if you are the real deal here is a checklist to see just how proficient you are. If you can check off most of these then pass this list along to your clients so they can test the next firm who promotes their BIM capabilities.

1. Programming and feasibility – converting programming data into massing models
2. Visualization of complex shapes – nonlinear fabrication (i.e. Disney’s Opera House in LA)
3. Visualization of finished products, the reference model – photo-realistic renderings and virtual tours
4. Design iterations and variations – showing the evolution of the design and different solutions
5. Construction Documentation and layout
6. Quantity take offs and cost analysis
7. Automated integrated specification; material properties and attributes (objects know what they are)
8. System clash or conflict resolution (objects know where they are)
9. Construction Administration (scheduling and work optimization)
10. Communication tool in all phases of a project
11. CAD CAM manufacturing and offsite fabrication
12. Shop drawings and installation data
13. As-built corroboration and systems commissioning
14. Facilities management interface
15. Maintenance and operations
16. Inventory Control
17. Database for renovations and additions
18. Equipment performance simulation
19. Building energy use simulation
20. Virtual collaboration (i.e. BIMStorm)

I also recommend you look on pages 182-183 in our book to see the evolution path for a firm developing its BIM capabilities.

Here is a short video of Kimon Onuma, a BIM Savant, sharing BIMStorm. Every firm serious about BIM may want to consider playing in a BIMStorm.

For a free copy of the BIM Chapter send me an email at rex@rexmiller.net. Once you read this chapter you’ll probably want to read the rest of the book.
