I agree with many of the comments made. I will also admit that I don’t know much about these “BIM Specs” programs (I edit my specs using MS-Word).
Maybe my next comments will come across as jaded, but the firm I am working for has recently gotten into the BIM world. I got my first set of drawings (partial set) for a larger project a few weeks back from a Project Architect. I wasn’t sure at first the reasons for the results I was seeing…whether it was limited Canadian experience, limited experience with the software, not enough time to produce the drawings…or a combination of all of the above. My first thought was I would have been embarrassed to hand in drawings of that quality in third semester at college 23 years ago (I had to correct that…I graduated 20 years ago, so I had to add more time on)!
What I am amazed at is the fact that it seems that a lot of the same issues I experienced over the years when the mouse in my hand was drawing lines and not highlighting sentences and paragraphs were still painfully obvious in the drawings I was looking at now…anywhere between 10 and almost 20 years after the “breakthrough” of 3-D CADD! (yes I know, the D for Design has been dropped from the acronym…or has it with BIM?)
But there is a common thread. Conversion. And I will qualify an earlier statement about my firms first foray into BIM…in the CAD stone ages (AutoCAD Release 9 or earlier) they actually used ArchiCAD or Architrion on Mac for design and then DXF’d the drawings into AutoCAD for Mac for the working drawings. I know 2 firms that did this, but the other further complicated it by using AutoCAD on PC…which 20 years ago was nowhere close to being as easy today as it was then (the only networks back then were “Sneakernet” where you copied files onto a floppy disk and ran it over to another computer across the office…but I digress).
Where the whole BIM concept falls off the rails is when not all of the Project Team are using the same software. With these recent projects, the BIM software spits out AutoCAD files for the Structural & MEP (hey I’m getting some of the US acronyms)consultants. I am getting PDF files of progress drawings that are 12MB because of the way the translating happens. The one project it took me the better part of a morning to print the M&E drawings! Something that should have taken me 20 mins worth of actual paying attention computer time.
As I have said in the past, and I will say again and again…we should really learn how to draw well in 2-D before we think about drawing in 3-D!! Of course I say the same thing about 2-D CAD drafting…it’s not hard to understand why computer generated drawings of today don’t look anything as good as they did of old when a CAD drafting monkey has never held (or had to clean) a technical pen!!
Understanding the spec writing process, and the intrinsic complexity of it; combined with my past experience with CAD(D) I can’t help but ask myself one question…if computer-assisted drawing has taken this long in it’s infancy, how long will “intelligent, automated” (BIM-driven) computer-aided specification writing take to successfully come into it’s own?
Call me a pessimist if you will, but I think I will be retired before that day comes!! (and I am not as long in the tooth as some members here)
(and yes I agree with Anne…I liked John’s “faster mess” comment too…maybe because I have seen it first hand…over and over and over again)
