The BIM Blink

The BIM Blink

BIM - (Building Information Modeling), which combines the objectivity of progressive cad, also strategically offers the practice of four dimensionality (4D = 3D + time,) & can generate queried databases. It renders with striking photorealism, and allows for complete building sets to be executed in profoundly different ways from ordinary traditional and digital drafting. BIM technology incorporates a practical, egalitarian system by using parameterized tools as its foundation. These parametric objects, somewhat familiar to those using cad, are extensively more accessible and can be managed much more comfortably within the framework of BIM programs. However, BIM projects are often misunderstood, because its methodologies and principles are still being defined within current permutations. BIM implementation relies on this very scope, presently being shaped.

The foundation of BIM is the use of objects in lieu of 3D drafting with vector based lines, which ultimately created forms, but which led to bulky sized 3D files that were hard to edit; in other words, non virtual, non sustainable 3D cad files. BIM erases this problem automatically. Because BIM objects are: built based on typical standardized divisions, have been pre-coordinated and packaged to contain all the necessary information common to a project with programmatic development. This containerization has served to address both commodity and nuanced element pertaining to the architecture being considered. Inside the container all programs are in a multiple stack as sequenced families. This sequence is subsequent to the research and development by that which the manufacturer stands behind. In essence, think of the BIM model, already having the shop drawing information built in as per the manufactured unit, system, or type, and can be augmented by the designer based on future determined points. Of course this applies when only those manufacturers producing BIM objects are involved with the BIM data they represent. It has to come from BIM, first hand, to truly represent.

With BIM technology, the exploration of interstitial, aggregate space is performed in ways quite varied from what typical designers normally practice with drafting. Actually, with BIM technology, architects have been compared to the early builders who had built with modularity and derived a building practice from this. A strong de-engineering, de-constructing, component is felt mostly when executing a BIM project but need not be considered austere. Rather than what might be felt drafting, as linear mediums are not always as precise and as predictable (especially when floor plans can sometimes stack up incorrectly, a frustrating dilemma) the relative ease of execution, with BIM, can be felt as enlightening. When building vertically in BIM technology, a seamless, imperforated spatial continuation exists, and allows for more site and space specific views. This means there is no worry for selecting something off in space that may overlap an object in the foreground. With BIM this is never an issue.

The BIM revolution will be gradual, perceptions of this technology show that is slow to be accepted. The fact that this methodology is perceived as imposing reveals the paradigm shift but it isn’t at all unattainable, as far as I see it. Written by Joseph J. Nicholson

I will have to learn from you! I am looking forward to reading more.

I look forward to this as much as understanding people's perceptions of how learning is taking place in the "here & now", with BIM.

The culture of BIM is certainly exciting and I hope to be able to teach this on a basic level to as many in the AEC industry as possible. Of course, it's by far more interesting than what we're hearing about now. With the advancement in technologies, it's sure to be way more prolific. Also, it's more than just modeling, however modeling is the major component, without it proper information configuring becomes muted and 3D models would remain static and only offer use for "pretty pictures".

In grad school I had a very wise city planning professor whose main interest was how information passes through communities. As I sat in his class, I felt his words course through my veins; it was a healthy kind of shock therapy. With BIM, I believe I know better what he had meant then, as he does now, because BIM is "power planning". When you execute a project, it can't hurt to be right more so than not.

What you do now will be the crux of what the industry will focus on for years to come. You certainly won't be learning that from me, but still feel free to check in to get my commentary, if you'd like. Good luck and keep me informed.
