It's only possible to build a reliable model if the correct families are used. While there's a huge online library of families available from the manufacturers of sprinkler components, there's still a lot which aren't.

We're constantly growing our Revit library all the time to ensure we model the correct equipment in line with the tech subs provided to us at the start of the project. Anything that we don't have will be created to ensure the model contains all the correct components and that everything is truly represented from a spacial fit aspect.
