Thanks all for any input, but here is a synopsis of the catastrophe we had in our HQ this past week.
We were installing some new equipment and had brought in a concrete cutting company to take off the top slab from the basement floor. During the process it was realized that the concrete was 14" thick, so they came back the next night to start ( I was not informed about this ). Needless to say on there first pass of 6" or so they completely cut through 9 seperate conduits feeding our entire east wing. Now if I was kept in the loop this wouldn't have happened because I never would have approved a cut that depth withought x-ray, but regardless it still has to be fixed. Now for the question
I've always followed the rule of if it's PVC it needs to be run at 18" deep. Now after checking with Table 300.5 I've found that under a building the minimum depth is 0"? Is there no code that protects this from happening, or have I been costing myself money for all these years? i mean some of these conduits were within 3-4" of the top of the cement.
Also I know they make underground feeder splices, but the ones I've seen are for very small conductors. Has anybody else ran into a situation like this and spliced the feeders in the conduit and repaired the conduit with the 2 piece PVC repair kits?
Thanks for any input
