View Full Version : Getting the "I" out of our BIM models

On the heels of this thread: http://forums.augi.com/showthread.php?t=133957 we had another staff meeting/discussion today about the direction my boss is wanting to take our company and the services we offer to clients. Basically we want to try to glean as much cost info, maintenance info, and other info out of our models as possible. We're even planning on things like life cycle cost analysis that will clients better budget for maintenance costs down the road (i.e. budget so much per year instead of having huge repair costs sneak up on them).

One thing we were discussing is how to best document what finishes are used in a building. For each room or space we would like to document every type of finish used, including manufacturer, any pattern or color names, pattern or color numbers, and possibly even amounts of such materials.

Now of course for some things it will be easy. For ceilings, just schedule your ceilings. For floor finishes, just place 1/8" thick floors on top of the structural floors (as we've been doing for several years now) and schedule those.

The big issue I see is walls, specifically wall paint. Sure if a room is all one color, or only has 4 walls, it's pretty easy to document what paint color is used. But what if the room has more than 4 walls? What if it has more than one color in the room? We tossed around a number of ideas, including different wall types, splitting surfaces, or maybe a wall-hosted family that could be tagged and scheduled. All of these ideas seem like it would be hugely labor intensive, and a massive pain if any walls ever move. With wall types you'd have to have thousands of different types for every different color, and color combination of colors on each side of the wall. In the end we're really looking for some way to tag a wall and have its paint color show up on a "Paint Plan" of sorts.

In the end it's all about providing the end user (client) with information they need about their building in a way that's easily accessible. What if 5 years down the road the client wants to use a paint that's in one room in a different area? If we had this information documented it would be easy to find the room and find out what paint brand/color is in the room. But getting that stuff scheduled just doesn't seem feasible with the tools Revit offers.

Revit is all about coordination and being able to document information about a building. But something as simple as paint colors seems a near impossibility in terms of keeping up with it, keeping it organized, keeping it correct, etc.

Has anyone else tried anything like this or have any ideas we could try?

In RAC 2012, we are looking at using Parts ( for Floors, Ceilings and Walls ) and then Dividing them and applying different Finishes to the divided areas to try to control them better. Parts can be scheduled and thus you can keep track of complex interior design/material locations/amounts.

Looks promising thus far.

I have only briefly played with parts when 2012 was first released (I didn't have time to beta test this year's release). I was thinking that parts was more of a view-specific kind of deal. Is that not the case? I will definitely look into that.

So indeed parts do look promising. Still some limitations, though, it seems. If I create parts from all my walls, I don't see a way to select all instances of a certain layer, i.e. all gyp board layer parts.

Also to be able to tag the parts, the parts have to be visible, and in views with parts visible, the corner join looks HORRIBLE! We may have to dial back to a coarse plan with our walls set to default black solid fill pattern for the coarse fill pattern setting, so that the parts can be tagged but the individual parts aren't discernible (I'm thinking for a painting plan or whatever).

Another issue I'm seeing is that I can assign different parts to be different materials. But when I tag them with a Part tag, it reads the part's Mark property, and if you assign the same mark to multiple parts you get a "duplicate marks" warning. Probably not a big deal but not really ideal to have that thing pop up every single time you apply the same mark to multiple different parts. Not sure how that might affect model performance if you have hundreds or thousands of parts all set to the same Mark and all generating that warning.

Have you considered using Revit Roombook Extensions? It's an add-in available under subscription.
There are some videos in Youtube, such as this one:
