I'm sharing this find because I hadn't done my good deed for the day yet.

I drove past a concrete place yesterday and their stack of precast blocks made 
me wonder if they have precast concrete slabs.  Yes, they do.

The pad in the attached drawing is a stocked item because the power company 
uses them for ground mounted transformers.  By sheer stupid luck, the opening 
built into that slab can meet up with the built in conduit openings in a 
dual-bay enclosure we're about to deploy.  They're not a perfect match, but 
they're plenty close enough.

A guy who does line work for the power company shared documentation with me 
which shows the transformer to go with that pad weighs almost 12,000 pounds. 
Given that, this thing ought to be strong enough to support any equipment 
enclosure I could possibly fit on it.

It's $630 from a local precast concrete company.  I'm waiting for the GC to get 
back to me and tell me if that's actually going to save anything vs pouring in 
place. Regardless of whether it's cheaper, it simplifies logistics because the 
contractor with equipment to move and place the enclosure could also move and 
place the pad.  That's fewer people to coordinate, and nobody has to wait for 
it to cure.  I do have a notion that it should be cheaper due to labor savings, 
but I'll know for sure soon enough.

I assume power companies nationwide use ground mounted transformers and that 
any of you could get similar precast slabs for things you might be installing.  
 They'll precast you a custom slab too, but I like the fact that they just have 
these laying around in case the power company needs one.
