This is exactly what we are proposing. The structural engineer does not just want to make holes in the slab around precast pull boxes that we have installed in grade. So, he is proposing that he design the pull box and integrate it into his structural slab design. The size of the pull box will be as dictated by the NEC at a minimum. What determines the depth of a pull box? Section 314.28 states the (2) min dimensions for the sides of the box based on the number and size of conduits entering the box, but where does the code refer to the depth of the box? I have a situation on a job where there is an existing pullbox that needs to be replaced. Sounds simple but the box is almost 7 feet wide and 4 feet tall. It also has 28 4" conduits in it. That asside it only has 20 inches of clearance in front. There is a chiller in the way. 110.26 says minimum 3 feet.

PVC conduit enters one end of box and se cable clamp is at other end of box. Should I run a separate ground wire through PVC conduit to ground pull box. (SE cable run in conduit must have outer jacket intact.)
