Need for Grade Beams?
Need for Grade Beams?
(OP)
I am trying to avoid using grade beams in an industrial renovation. It is essentially a new building being constructed inside of an existing shell.
I will have concrete piles spaced approx 8-10 feet in each direction with pile caps. Some will have two piles to a cap. The piles will be embedded in the caps enough that they're considered fixed. The floor slab will be 12" thick and will be tied to the pile caps.
I see no need for grade beams except in a few locations where I need some lateral distribution. I'm looking for any experience, thoughts, input, suggestions you may have regarding this layout. Thanks.

msquared48 - If possible, I'm trying to elminate the need for forming up the grade beams - added time, labor and expense. Dropping the slab won't accomplish that. It is not a high seismic zone but the soil is not good, hence the piles.

Since bottom reinforcing needs to be placed on top of the piles, how much is the embedment of the piles into the slab?

There is nothing wrong with your concept. I am not sure why grade beams would be of benefit, and they would certainly complicate construction.
