There is existing conduit from one electrical panel to feed another electrical panel locates at opposite wall in the same room. The conduit run down and below the slab between two panels. The client wants to demolish and install entire new slab for the room but want to keep both panels at same spot, energize as much as possible as the panels powered other untouch areas in the building. What is the best solution for this? Should rerun overhead conduits between two panels, then remove underground conduits when new slab is poured? Other question: can the elec. panels be supported from structure above with unistrut in lieu of wall studs?
 
Why can't they destroy the slab and leave the conduit? It should be pretty easy to trace where it is but if that is not an option sure go overhead if you can.

You can support the panel anyway you want as long as it is secured and safe.
 
Maybe it's cheaper to just destroy the entire slab conduit and all. I would do as you said and run another conduit, reroute all the wire through it, abandon the underground conduit, and then let them destroy it.

Agreed.
Probably going to be destroyed anyway. Wouldn’t doubt it’s going to be more expensive to worry about saving a conduit.
 
Yes, do it all in one shot. Go overhead, remove the bottom-conduit wire and locknuts, and let the demo crew remove them.

If the ceiling isn't too high, the old wires may be long enough. All you need to come back for is to install the knockout fillers.

For temporary support, strut would be a better choice than all-thread. I'd have be there to suggest anything with more detail.

There is no ceiling, this is a two story space, can the panel be supported from deck with unistruts or some kind of supports to hold the panels? The wall will also be removed and put in later.

Yes, you can build a pedestal with strut and strut hardware.

But, how can you bolt to a floor that is being demo'ed?

Can a panel be secured with unistruts at 4 corners from deck above and not bolt to floor?
