So the shell of this building was built before we stepped foot on the job. GC ran transformer and generator pipes. There is no building steel wire though. Anyone had this happen to them before?

Any ideas?

You mean there's no steel in the frame?

 

[Meadow]

The steal is encased on concrete?

 

[btharmy]

Is it all pre-cast concrete?

 

[Skipbayless]

It has steel in the building, there is no write coming from the steel, which is encased in concrete currently and up to grade. Building ground requirements state you have to be close to the bottom with 20ft continuous steel/metal conductive material. Looking like we will have to dig and hammer drill unless any of you have a better suggestion.

Is it a clear span building? There's gotta be I beams in the ceiling available

What you mentioned happens all too often around here.

Our AHJ is trying to get other inspectors involved and catch it before the footer is poured but it's been a slow battle.

So, they allow rods, CW piping, building steel etc. , per Code.

The building is block, the ceiling is wood, the only beams are on the veranda and they also are wood. It calls for a triangular ground rod layout as well.

Were you the EC of record when the slab was poured? Or was this something the GC started before he had an EC? If so, I'd place the responsibility of getting in the Ufer ground back on the GC.

Here, we would simply have to install ground rods in lieu of the ufer, but I have read of areas/inspectors that would require the GEC to go to any new rebar/footings.

Do you have any reference that is legal? There is already a triangular ground rod system requested, will this suffice?

The GC took responsibility and offered his man power in anyway needed to assist us. Just trying to learn by questioning other options.

Is the slab wire mesh or rebar?

Chipping hammer or pour a Ufer adjacent to the electric room that meets code.

BUT I would meet with the inspector first and discuss his viable options.

 

[Skipbayless]

It is rebar.

Id ask the contractor to chisel the concrete for the correct ufer. The AHJ might not allow for a triangle ground alone they might. But my interpretation is that you need a ufer by code.

 

[Skipbayless]

Yeah, they are going to. I've been persistently asking. I think they are going to get it done now.
