Back when Tanglewood was being built we had to use a product called LiteDeck
to make the runs across top of ICF between the first and second floor. It's an amazingly strong product that uses a mix of Styrofoam and steel beams for strength, and we ended up making the floors very thick (19"). We ran this all the way out across where the outside deck is, which they then covered with rubberized membrane for water proofing purposes and such.
Usually one never even thinks about the decking at all, frankly, but with our snowfall overnight I was presented with an interesting picture in the morning. You can clearly see how the decking is run in this picture, with the "deep" snow being where each LiteDeck panels alternates between steel beam and Styrofoam insulation.
I thought this was pretty danged cool myself.

|Pretty neat to see how the alternating foam and steel translate up to the deck.|
