Im at a jobsite and someone had the concrete guys run the conduit for floor boxes before the electrical contractor was even pick. They ran 4" pvc and had 90s and Tees above the floor.There is like 12 floor boxes and one stub up for a home run near a beam. Is this common practice?

4"? How could he possibly connect 4" to a floor box? Above the floor? Do you say the pipe is on top of the concrete? This stinks in every way.

Schedule 40 or 80? You could run electrical and sewage together to complete the sh*t job!

Is that even electrical PVC it looks white?
Did they use sweeps or plumbing 90's?

Plumbing 90s for sure. And the end of the 90 or T would be just above the concrete. Just a big 4inch hole

Ask the Concrete contractor to give you the approved submittals on the floor boxes so you can order the right stuff to complete the installation. :)

You could probably get a fish tape going into the first plumbing 90 and snag it at the other end with another fish tape. If there are any plumbing 90s mid stream you might really have a hard time with it.
It looks like there is no concrete poured yet so why not just rework the underground electrical the correct way. A floor box is not designed to mount to 4" drain pipe. OMG x 2

Maybe they can use the pipe for running beer lines to each desk. Then you can add conduit next to it for power and data. 👍

Sooo just went back and talked to the concrete guys. There was sweeping 90s. And apparently there was a union master electrician working concrete today with them and told them how he would lay it out.
