Does anyone recognize this floor system? 1

I am seeking info on a proprietary structural floor system used in an '80's office building here in NJ. The floor deck consists of approx 4" thick precast panels about 6' wide and 20' long. Open web joists appear to have been cast into the the panel at the shop. The top chord of the joists is not visible, its completely buried in the slab, along with one or two inches of the tops of web members. Its not a Hambro system because the soffit of the deck appears very smooth, no plywood was used, and my understanding is that with Hambro joists you can also see a portion of top chord. Its not a Filigree precast slab because as far as I know they do not provide a joist-and-slab system.

Does this ring a bell with anyone? First time I've seen it.

From your description, it sounds like Hambro. However, you are ruling that out. Hambro is still around. I would give them a call. If it is not theirs, they can tell you who their competitors are (were).

Good luck
