Contractor poured an exterior slab too low resulting in the exterior metal stairs hanging about 3" above t/slab. I need to provide a 'ramp' up to the bottom of the stairs for accessibility and anchorage. The material needs to go from feathered edge to approximately 3" over an area around 12...

ASCE 7-05 Figure 6-8 gives arched roof coefficients, but my building actually has half an arch with the windward wall being 20' tall and the leeward wall around 40' (or reverse). My question is whether it is valid to run calcs using Figure 6-8 and only use the roof loads given for the first...
Thanks for the info. I have contacted a company about the GPR, but it is not precise enough for the exact dimensions I need. They use the GPR more for soil densities than concrete thickness. I'll have to see if there are any ultrasonic testing companies here in Florida.
Does anyone know of a way to have slab thickness verified without coring through the slab? If so, are there any companies in particular who might specialize in this operation?
Thanks,
Nick
