I've had a geophysicist survey the property. The soil in not expansive, but
reported as 'gravely silty sand'. There is no seismic danger, but I plan to use
Simpson tiedowns at the slab and at top to provide wind-force strength. Neither
are required locally. The tech report says at 1.5 feet and below there are
native soils. It further says, "Allowable bearing pressure 2000 psf at
18", 2500 psi @ 24". The test pits indicate 98.4 to 103.7 pcf at 1.5'
I can give you other test data as needed. The plan is to use a monolithic pour,
with 2 pcs #3 rebar at the footing base and one #3 higher up. Also, either #10
6x6 remesh or #3 rebar on 16" centers in the slab, along with fibermesh.
Construction will be both 6" KC Panels (SIPs) (www.kcpanels.com) with
polyurethane insulation and 6" steel studs, with stucco over OSB and gyp
surfaces. My particular question is largely the advisability of 'floating' the
slab over the beams. I'll appreciate any other suggestions and/or questions.
