As each soil sample is recovered a representative sample is collected. The soil samples are taken to the laboratory where they are visually classified using the Unified Soil Classification System (USCS), and the color is identified using the Munsell0 Soil Color Chart.The soil description with the appropriate color and USCS symbol for each sampled interval is presented in the hand auger soil boring logs. Results Hand auger boring(s)were excavated to e�lore the shallow subsurface near the foundation. Samples were collected at one-foot intervals in the hand auger borings performed near the location of the distress.The boring encountered fine sands (SP)from the surface to four feet below land surface (bls) Standard Penetration Test(SPT) Method ' The SPT boringsare performed in general accordancewith ASTM D-1586 PenetrationTest and Split Barrel Sampling of Soils,for the purpose of obtaining irYformation about the deepersoil conditions and to collect soil samples for laboratory analysis. Engineering properties such as relative density and soil consistency of the in-situ soils can be evaluated using this method of soils e�loration. The borings are advanced into the ground using rotary wash drilling techniques. Drilling fluid (mud) is used to flush the cuttings out ofthe borehole to prevent the boring from collapsing. The soil samples are collected with a split spoon sampler. The spoon is driven a distance of 18 inches into the bottom of the hole using a 140 pound weight dropped from a height of 30 inches. The number ; of blows required to drive the spoon each 6-inch increment is recorded on the boring log,with the last i 12 inches reported as the "N" value for that sample interval.
