Same pool as last night,,,different question. I was not hired on this job until last week. Indoor underground pool in a finished basement. Water line level with floor line. The pool had already been poured when I got there. I don't know what steel is in the form or what. All the PVC pipes come into the pool pump room out of the slab with (1) #12 green THWN embedded in the pour with the pipes. I don't know where the other end is. (rebar in form I suppose,or how they attached it. There are 3 windows within 5 feet of the water, and a metal rail and ladder will be installed. If I had been there to start with, there would be a #8 stubbed up by the base of ladder, the base of the hand rail and a #8 to the reinforcements in the cement. What can (or would) you do now? One #12 was all they gave me to work with.
