My understanding about "waterproof" decks is not "Will they leak?" but "When will they leak."? Consequently I _always_ require PT framing.

Also, the guardposts are the kind that sit on top of the deck. I hate those. The support connections appear to penetrate both the deck sheathing and the bituthene membrane. On one of the photos (#12), you can kind of make out voids on the top edge joist where the guardposts would be. Could that be a source of water intrusion? Just throwing that our there.I too noticed that the balcony framing is not pressure treated.This tragic event is so sad. In my own assessment, I wonder what else can a structural engineer do to prevent this. PT or steel framing? Detailing with potential water intrusion in mind?Ricardo G. Gonzalez, P.E.
