Foundation Recommendations: Provided estimated settlements are at intervals the structural tolerance, a shallow foundation system consisting of either perimeter wall footings or isolated pad footings should offer adequate support for the proposed structure, assuming the whole removal of all surface organic materials, proper subgrade preparation, and correct fill placement, as described later. primarily based on the SPT "N" values obtained from the soil boring a net allowable soil bearing pressure of two,500 psf (in far more than overburden) is estimated for the existing shallow soils found over the site and for structural fill as described in this report. This bearing pressure estimate is predicated on the complete removal of all surface organic materials, the removal of organic materials beneath footings, and also the filling and recompacting described later during this report. Settlements for the proposed structures and also the anticipated fill, based mostly on a control capacity of two,500 psf, are estimated to be concerning 1-inch total. As mentioned previously, owing to the sandy nature of the materials, these settlements should occur because the hundreds are applied. A minimum footing width of 18 inches and a minimum depth of embedment of eighteen inches ought to be used for footing design for all structures if individual footings are selected.
