The structure has been evaluated with Roof Live Load of 30psf, Floor Live Load of 40psf, Live Loads of 15psf, and Soil Bearing Pressure of 1,500psf.

It is best to enlist the services of a local professional for such “location–specific” structural redesign. Local lumber yards sometimes have contacts for such services.
