I have a twisted little story.....that I can’t resist to share.
Imagine this: A building yet-to-be built. (can’t really give you pictures due to confidentiality but this should not take away from the story as the numbers talk here better than most pictures would);
Commercial high-rise, numerous basements, podium, a split tower with a dozen or-so floors.
My interest is still at the bottom basement level.
There are 114 columns to this floor.
There are 47 grids to provide the spatial framework to the structuring of these columns.
NONE (0, zero) of these columns are based on the intersection of two gridlines. A few are ‘close’ (as in sitting on a grid or in reasonable proximity to one, many are floating totally ‘loose’.)
Interested in more statistics? The 114 columns are made up of 31 (thirty-one) individual types, the maximum occurrence any of the types is afforded is 15, there are 12 types with only one representative for each.
Standardisation? What standardisation?
The ‘twist’ of the story is not in these numbers, though I find them quite entertaining. (and a lot of work, mind you).
The punch-line comes from IFC – as in the exchange format of the buildingSMART fame, the enabler of the ‘open BIM’, I’m ‘practicing’ on this job
No matter how I convert the source (Revit) file into the ‘ifc’ format, 4 out of the 114 columns come across rotated by a random angle.
