Capturing Ceiling Information for COBie Output

For whatever reason, a project we are working on has a requirement to capture pretty much everything into COBie, not just the usual maintainable assets. The developer has the idea that this will be an examplar for best practice, failing to realise that this approach is the opposite of best practice.

 

One thing that is eluding the team working on the project is the capture of ceiling information. The ceilings are standard Revit format - just a single system element with room bounding enabled. COBie fields are defined, but the ceilings are not being picked up as belonging to the room when the COBie information is exported. I've suggested turning off the room bounding property for the ceilings, but is there anything else that we should be looking at? Unfortunately, we have signed-up to terms that do require the information to be captured, so we are obliged to find a solution.

For the COBie Extension to be able to populate space fields, the Revit element has to be a room aware element. Unfortunately, ceilings are not a room aware category, so the COBie space information has to be updated manually.

 

Quick way to check if a category is room aware is to make a schedule and see if you can select Room or Space from the "Select available fields from:" drop-down. For example, this is the fields tab for Casework:

And this is the one for ceilings:

I thought there was an AKN page that lists the room aware categories but I can't find it right now.

 

Only workaround would be to get some Dynamo script that can look at the ceiling and see if it's close to a room and then populate the COBie field that way.

 

Hope this helps. And... good luck collecting all that COBie data... yikes.
