Rob Jackson over at Bond Bryan’s BIM Blog published a useful post earlier, about how to produce your TIDP inside ArchiCAD. I’ve shamelessly repurposed Rob’s hard work and done the same inside Revit.
What’s a TIDP?
Ah, that’s another one of those BIM acronyms for something we’ve been doing for years anyway – it’s a kind of Information Release Schedule: a list of all your drawings (and other documents) and the dates you’ll release them. You’ll find the requirements in your BIM Execution Plan (BEP) if you’re following PAS1192-2.
Revit Sheet Lists
Revit’s Sheet Lists are like the drawing registers of old, they’re a list of all your ‘drawings’. Whenever you add a new Sheet in a Revit file, it gets added to the Sheet List. These are great, but note that Revit doesn’t produce Issue Sheets or Transmittals (without a lot of hacking). You can turn a Sheet List into a TIDP though, just by adding a few Shared Parameters.
Adding Shared Parameters
If you’re following BS1192 document naming, you’ve probably already worked out that you need to add a Shared Parameter (SP) for each of the 7 fields which make up the file identifier. You need an SP, added to the Sheets category, for Volume and Level for instance. You’ll also need an SP added to the Project Information category for Originator and Project Acronym. All of these SPs and their data can be added to your Sheet List, and to your Title Block as below. (Ours is slightly customised to allow us to use our internal project numbers, which is fine as long as you write it into your BEP).
To make a TIDP, you’ll need several more Shared Parameters. Add one for Exchange Format, and add one for each date column you want in the TIDP, called Delivery Date Milestone 1, Delivery Date Milestone 2 etc. Put those SPs on your Sheet List and you can enter your release dates right on the TIDP. The milestones are typically the new RIBA workstages (0-6, you won’t need 7).
You can make Placeholder Sheets in Revit, which is something you’ll want to make use of. You prepare your TIDP at the start of a job, when the Sheets don’t actually exist. Just go to your Sheet List or TIDP, and Insert Data Row to make a Placeholder Sheet. When you come to need the Sheet further down the line, just choose the Placeholder Sheet from the list in the New Sheet dialog.
