CAD vs BIM Rendering - The Process

Today my company started on a BIM coordination project for a subcontractor for a major general contractor.  It is going to be a 2 month project and the subcontractor sent us their standard subcontractor agreement.

This is the point where as an Autodesk reseller, I have to ask myself, what the heck am I doing getting subcontractor agreements for services when we're just supposed to be selling you boxes of software.

Well, quite honestly, the entire scope of my company has changed drastically in the past 3 years.  Between making Revit content for manufacturers, converting 2D dwg drawings to Revit 3D models, subcontractor 3D coordination shop drawings, renderings, models and a whole lot more, there's hardly any time left in the day to actually sell the software.  Since the 2D year olds are still using AutoCAD, there's a lot of work to be done to help the contractors with their modeling, coordination and schedulling with BIM. 

So, enough of my little advertisement to you for BIM services.  Where was I...oh yeah, the subcontractor agreement.  The first line of the scope of work page:
1. To provide rendered 3D BIM drawings representative of contractor's shop drawings
and satisfy the requirements of XXXX(redacted) BIM implementation.

Whoah there Mr. Subcontractor.  You said 'rendered'.  I contacted them immediately to clarify that this project wasn't for renderings.

Here's their response:
I see how the term "rendered" could be a little misleading in these circumstances. We weren't using "rendered" as in a process of taking 2D and converting to 3D. We meant it in a much more generalistic fashion. As in "taking the existing 3D dwg and modifying it."
Please let me know if you need us to rewrite that and get it back to you.
 OK, now the fun part.  Some of you may after 3 years of reading my blog, realized that my mental word processing functionality is twisted and warped.  Here's my response to them.

Oh, you meant like for food.  Oh man, you just gave me a great Revit blog post.

From Wikipedia:


 is a process that converts waste animal tissue into stable, value-added materials. Rendering can refer to any processing of animal byproducts into more useful materials, or more narrowly to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale.
The majority of tissue processed comes from slaughterhouses, but also includes restaurant grease and butcher shop trimmings. This material can include the fatty tissue, bones, and offal, as well as entire carcasses of animals condemned at slaughterhouses, and those that have died on farms (deadstock), in transit, etc. The most common animal sources are beef, pork, sheep, and poultry.

The rendering process simultaneously dries the material and separates the fat from the bone and protein. A rendering process yields a fat commodity (yellow grease, choice white grease, bleachable fancy tallow, etc.) and a protein meal (meat & bone meal, poultry byproduct meal, etc.).

Rendering plants often also handle other materials, such as slaughterhouse blood, feathers and hair, but do so using processes distinct from true rendering.

Is that the kind of rendering you were talking about, taking AutoCAD byproducts and turning it into something useful like BIM?  I'l send over the verbiage that should be acceptable to all of us tomorrow.
 So now every time you say the word rendering, you're going to think of things like lard, grease, animal parts and all sorts of chicken guts and stuff.  Oops, I'm so sorry. I never meant to put that visual into your head.  To my friend Joe G. if you're reading this, remember the visual I gave you once that you'll never forget.  For the rest of you,  AutoCAD is a BIM byproduct.  It's what's left over from the model.  It's the useless lines and layers that has no meat to it.

Wasn't that a fun blog post?  Sir, are you rendering or surrendering?  I've got to get back to rewriting that contract now.  See you tomorrow.
