Last week, our Virtual Construction team sat down with the CAD Manager of our HVAC subcontractor for Autodesk. In our discussions, a recurring topic came up – why they can’t use Revit MEP for fabrication. One of the major reasons is spooling, which he had mentioned several times before, but hadn’t explained.
After they model and coordinate HVAC, they take the model and review for pre-fabrication. During this review, they bring up the model and select sets of components to pre-fabricate. From what I understand, they select each group of components and turn them into the equivalent of a Revit Group. The software automatically (sort of) creates cut sheets for each group, with dimensions, sizes, lengths, etc.
I didn’t realize that this was something that a software program could do and am amazed at how efficient it seems. Although I’m sure there is some work involved, this is the type of thing that we would like to do for all trades – select a group of objects that will be built/installed at the same time (for instance, a group of footings and foundation walls). “Cut sheets” would be automatically created, based on the selected objects sheets”, which would contain 2D and 3D views, dimensions, quantities, etc. Although, we wouldn’t want to use the term “Group” because it already exists in Revit. We could call it ‘Task’ or ‘Week’ – which makes a lot of sense, considering this is basically a schedule. Kind of like our Sequence Sheets (manually created for a project using Phasing in Revit), but a lot less work.
