Draft Revit NBL Content - Feedback 2

.
I’m up to my ears in work, life the universe and everything so, I’m only getting to review Stephens feedback in the morning as I’m an early riser, here is what I posted over on the NBL Linked-In Group this morning:-

G. Are COBie parameters really needed for wall constructions?
Some of them will not be relevant. Depending on the client requirements, on some projects, it is possible that none of them will be relevant. However, for consistency they have been included. Also, if you used an NBL wall object to build up a pre-fabricated wall construction then you may wish to complete the majority of these COBie FM parameters.

This reply is a cop out. Please actually demonstrate what COBie parameters are actually applicable to a wall construction, and which part of that construction.

If you Scope out your walls and then look at the COBie parameters you will see that very few are applicable. Stephen you have demonstrated your experience in programming, why would you flood a program with variables that you were never going to use?.

Revit is clunky anyway why make families heavier?

“For consistency” is not a good enough reason to do it, because its quick and dirty, and we have not had time to review what’s actually applicable and needed because we are working at speed to produce something, appears to be a more realistic driver for their inclusion.

I challenge your team to apply the COBie variable to standard traditional wall constructions and this pre-fabricated wall construction you site and demonstrate their usefulness in being included within the wall families.

Here they are ….

Most of them are ideal for mechanical plant and items to be maintained, and no doubt this list is going to grow with time.

We at the pointy end don't always have the most up to date computers, some are waiting for the 3 - 4 year replacement program to hit us and with the current economic situation what was 3 years is being extended until real economic recovery takes place.

In the UK, COBie will be used for cost, carbon and value information exchanges as well as O&M. So 'all maintained assets' becomes 'all significant assets'. The parameters you list are mostly Type parameters, not Component parameters. Components only need attributes for identity, location and quantity. But then some BIM authoring tools just don't do Types that well...
