I have a client who does not want any exposed conduit and boxes but he is planning on a precast building (gymnasium). Anybody ever tried to coordinate outlet locations and conduit runs in precast panels that are manufactured off site?

If so, how did you coordinate the connections between conduits in different precast panels?

What about trying to run down in the wall to below slab. How do you coordinate the connection? Also who gets to reach their hand under the 2 ton slab being help up by a crane and connect the conduits?
 
I don't see how this can be done easily, but perhaps a 1 1/2" dia chase that would line up between panels and then you could run LT NM flex thru it. And at the outlet location, have a styrofoam block placed to install a box and then grout around it.
 
That`s the most ridiculous request i have ever heard.........It`s hard enough to hit every wall in a slab never mind trying to hit a ko in a box dead on the money.NASA can`t retrive the space shuttle without spending countless amounts of money looking for a piece of foam that might have fallen off .This guy wants to try and do offsite work that would require millimeter accuracy
I like Toms` idea given a specific area to hit stub up and change over.

Unless your client is in the same financial catergory as Bill Gates, how do you purpose to have the precast company deviate from their profitable pre-casting design?
 
I happen to agree everyone. It is an unreasonable request to try and perform this task. Those pre-cast walls have no room for error, unless they rough in the panels at the factory I don't see how this can be done. It's always a crisis till they get the prices.

This is a question for the manufacturer. I'm sure this isn't the first customer they've ever had that wanted electricity.
 
Yes it can and has been done. Easy if you have a attic space to work with. Everyone must know how to read a print. Don't try it thru the floor.
