Who is Responsible?

[dik]

Further to a current thread and not wanting to hijack anything:

The Algo Centre mall that had the roof collapse and kill a couple of people and injure 20 more had a non-construcable roofing system that was ultimately the cause of the collapse. The roof was used for parking over the mall area.

Who would normally be responsible for the roof construction? The Architect, the engineer, or the precaster?

I would consider the roof as part of the building envelope with the Architect responsible for waterproofing and control joints. He would normally work with the engineer on this. I've also encountered the precaster looking after the entire topping, membrane and control joint issue, but only for stand alone parkades.

Just looking for some other thoughts.

Dik,
Where can see see your powerpoint(s)?

The first one is in ET Journal. The other two are/were part of a lunch and learn, and due to the inflammatory nature of them, they aren't publically available. In my opinion, the report is not particularly well done, and could easily be challenged. It's not that I can't defend my critique, it's just that I'd prefer not to.
