No any good leads yet. My guess is same as yours (W9 wire @ 12”). Thanks! - Martin
That's a tough one to figure out. Any good leads yet? I'll check our office library, but it sounds like a proprietary call-out. My guess is the 9 means a No. 9 wire. Maybe spaced at 12"o.c. Good luck with this one.

We are working on a project that involves an existing reinforced concrete building with the drawings dated 1937. The reinforcing specified for 3” slab over joists is BF912 Mesh. Does anyone know BF912 Mesh?
