We're trying to take our Revit models to the next level for clients who are willing to pay additional fee for this service. This will likely evolve into something like integrated project delivery.
To make this happen we're trying to set up schedules (either component schedules or material takeoff schedules) that will help generate cost estimates from the Revit model. The issue we're running into is getting cost information from wall sweeps.
The attached Revit model shows something we might do on a typical project. There's a metal stud wall with EIFS, and a brick wainscot. Then up top there's an EIFS cornice, and then the roof above. I can get a wall schedule to read the walls (and account for the presence of the door), and I can get a separate schedule to read the hosted EIFS cornice sweep.
The problem is the brick sweeps as part of the wall type. There has GOT to be a way to get some quantity and cost information out of there. Sure there are workarounds, but it seems like those get away from the functions Revit has designed into it for this type of assembly. Sure I could do the brick as separate hosted sweeps, but that seems counterproductive since Revit's wall types have provisions for building the sweep into the wall type. In most cases that's a better way to do it, from a documentation and revisions standpoint.
The other issue is the duplication of EIFS material at the top of the wall, behind the cornice sweep. In reality the EIFS on the wall would stop at the base of the cornice, and continue up some additional angled framing. How can we account for that in schedules?
This is really our first dealing with quantity and material cost and takeoffs from a Revit model, so if anyone experienced with this kind of thing could lend their thoughts, it would be greatly appreciated.
