More on Details

People have knowledge about building and BIM would tell you to draw necessary details enough for general purposes of BIM.  Their reason: "value".  So, it's a waste of resources to hire a crew to draw the anchor bolts of a kitchen cabinet.  Also there're other reasons like software/hardware performance, data query and analysis performance, capacity of machines ....etc.

While it's too ture to argue on this issue, our mind become too solid to take a further step or just to put a fullstop at the current prospectus of BIM.

But just ask one question: are there eventually any drawings showing the hanging bolts supporting the kitchen cabinet at the end of the day?  Surely it's "yes" - not only the fabricator, but also the project engineer have to approve it's structural adequacy based on the drawing duly prepared!

There must be  "advantages" to put any data about a building into a BIM, where they appear and are referred to during a building life cycle for some time.

This is the axiom of BIM!

What we should have asked is "if we make effort to include them in BIM, is there a positive value generated?"

That's why we have a balancing point about what to/not to build in BIM.  So currently, we wouldn't expect to see an 3D anchor bolt in a BIM.

But the "balancing point" itself is not the axiom! 

That is, it's existence and position is not always true.  It should be moved or even vanished when BIM technology keep advancing so that we take lesser and lesser effort to put more and more details inside a centralized database.

The future of BIM is not hard to imagine, because it's fairy clear that we don't need the chemical equation of a waterproof membrane to appear in a building project.
