Design criteria
Design criteria
(OP)
For design criteria using California Building Code 2013, we called out:
1. Soil bearing pressure 1500 PSF.
2. Concrete strength at 28 days: 2000 psi
3. Reinforcing steel: ASTM A-615 grade 60
The plan checker had questioned the above values. Any reason why?

I agree I would not use anything less than 4000psf for concrete unless a footing, then 3000psf.

What kind of a structure is this and what is the soil like?

To that end - 1500 psf soil bearing pressure is lower than I've normally seen but maybe its a California / seismic issue?
none the Less - the allowable bearing pressure absolutely needs to be verified by soil testing.. this was not mentioned. Has it been performed?
agreed on higher concrete strength
