I know that SU isn’t technically “BIM” but one can certainly embed a LOT of information about a project in a Sketchup model. Not to mention use that model to discover clashes, errors and omissions in the plan set and guide construction specifications and scheduling. Couple all this with Sketchup’s relative shallow learning curve and ease of use and, I think, we have a pretty compelling package for constructablity analysis. I know John Brock, for one, is deep into this.
There are studies out there that purport to document the return on investment for the cost to produce a BIM model at 200% - 500% or even higher. None of these studies, to my knowledge, are referencing the use of SU as a BIM platform. Nor, are they done in my specific field - construction of high end custom and estate homes.
Given this opening, here’s what I’m trying to do and looking for anyone here on these forums with any experience and / or ideas in this regard:
In my custom residential field, it seems most the players - contractors and a lot of architects - are as fearful of change as small children are of things that go bump in the night. I show these firms the level of detailing and information I’m providing in my construction models with the goals to 1) have them engage my services (of course) and 2) bring this archaic business, kicking and screaming if need be, into the 21st century. In my years in this field, I’ve seen far far too much waste caused by incomplete or misunderstood plans to be comfortable with my role in this waste.
To me, I look at any model I’ve created and the advantage of it to the building of a home is strikingly obvious and needs no explanation. But, I’ve always been a geek, so I am at a loss to know why others do not have this same reaction.
Therefor, I am trying to quantify the savings that my “BIM” model brought to my most recent project. For marketing purposes. And, here is where I’m looking for any thoughts / discussion - how to quantify this? Its hard to put a dollar cost on work that didn’t have to be torn out and redone because the model prevented the error from occurring in the first place. Its equally difficult to quantify the increased productivity / accelerated schedule that can be attributed to having a detailed model to refer to. Yet, in a conservative industry such as home design and construction, this seems precisely the information needed to make the case for modeling.
Has anyone had any experience in this regard? I’m all ears.
Thanks to all who make the effort to read through all this. Any thoughts or info are greatly appreciated.
