SI’s, CCN’s and Addenda … oh my. (Part 1)

Back on September 9 2010, I did a quick article on Autodesk University and pointed out some of the resources available there. In this post and the next few I’m going to be focusing on an extremely important topic that all Revit users face eventually. Contract administration.

In AutoCAD, contract administration can be handled quite simply because of the way AutoCAD uses separate DWG files to store information. In the firm I work for, after issuing for construction all the DWG files were copied into a special folder so a restore point was created. If changes were made to the drawings that were to costly to implement. All one had to do was go back to the IFC drawings and copy whatever sections you had changed back to the working files. Or optionally you could just copy the wall section within the CAD file and modify the original to the new design. That way, you could roll back a design change that wasn’t accepted. While I still copy the Revit file to a separate directory after I have issued for construction, copying between Revit project isn’t as easy as with AutoCAD. Wall sections and other “model” based views are model dependent and items like tags and dimensions don’t copy across.

In the next series of posts, I’m going to be looking at the Revit way of doing contract administration. How to modify the building drawings while still keeping the old copy handy and in the same Revit file. This doesn’t include using “Design Options” or “Worksets” because that’s not what those features are meant for. Also I’ll be looking at how to keep the views and information organized within Revit so that others working on the project will understand what is current and what is old.

Before I jump into all this next weekend, YOU need to do some homework. Not much just some reading. Over at Autodesk University Online, Jim Stoneberger has written an excellent article on how he handles contract administration in Revit. You can find the article here, its a free download. You don’t even have to be registered with AU to get it. This article forms the foundation to this series of posts I’m writing and I’m going to be quoting and referring to it often, but I won’t be going over what is in the article itself. So I encourage you to read it and maybe start to try using his method if your comfortable enough with your Revit skills. Also it would be a good idea to start using the method on a project that only you are working on. Otherwise, it could get confusing real fast. The article is brief and doesn’t cover all that will come up like I’m trying to do here.

I’m currently using this method on 4 projects our firm has under construction and have been quite pleased with the results and how easy it has been to implement. It does take some getting use to. Revit is a paradigm shift in drafting, so it affects everything in the project.
