Recently, I designed a project where I did not specify the exact route for the conduits frm the transformer to the main switchboard. However, I obviously could have done a better job, because the main switchboard ended up being directly over a building footing. Rather than call me up, they went ahead and installed them and placed the concrete.
Well, long story short, the structural engineer did some calcs, and is okay with leaving the conduits in, but now we need to make some sort of break in the conduit to avoid crushing it in case of building settlement.
Would it be code-legal to cut the counduit, and install a piece of larger-diameter conduit over the cut, with some rubber "boots" held on with stainless gaskets? It's kind of home-brew, but I'm looking to avoid a bunch of excessive costs.
