The designer’s requirements for COBie – BIM
From a practical standpoint, what do you find will be the major hurdles implementing COBie?
I think that the number one difficulty is that people don’t know what COBie means for them.
In part, yes. Many large campus owners I have talked to continue to pay for man years of reproduced and wasted effort because the guys with tools (I mean “spanners”) get stuck figuring out things.
To properly specify COBie, owners need to answer three questions: “What resources do I keep?” , “What advice do I need to know to do that work?” And “How will the data work across my enterprise?”.
Owners that have not addressed these 3 questions will find only limited value in the COBie data they get. I utilize my COBieScorecard as a step-by-step manual to help owners to execute COBie.
Why not more owners understand the value of COBie?
While each owner has their own rationale, it all comes down to exactly the identical explanation: “We have just always done it like that.” In my experience, most owners continue to make the very same mistakes again and again, rather than just take the chance of creating a new mistake.
I guess the only real way to make progress for many offices is to induce new sub-categories for time spent on different job orders in associated cost-accounting systems.
What about designers?
Yes, designers also have to understand what COBie means to them. For instance, most designers don’t understand that even if owners don’t answer those three questions, their layouts already specify what ought to be in COBie. For designers, COBie is simply the compiled listing of assets that are scheduled. It’s just one more way to deliver the exact same info — no more, no less.
Actually, the number one reason why designers have issues exporting COBie info from Autodesk Revit is that they attempt to export an entire layout in COBie. To do so shows that the Revit operator does not understand the intent behind COBie.
If designers already deliver COBie information on drawings, what’s the big fuss about?
Good question. I believe most people overcomplicate COBie because they have a tech to market or a promotion agenda to drive. Technology can help, but anyone executing a drawing schedule, even using CADD, can turn that information into a COBie-formatted file.
Having a bunch of new acronyms for delivering “information that matches drawing schedules” may look to be a good concept, but most people run away whenever a new version of this “wedge diagram” seems. Designers are in the game of design, not the business of information technologies, I believe we ought to keep it that way!
