To determine the total <br />literarrasistance, the contribution of the zone above the point <br />of fixity, to passive resistance, should be disregarded. For <br />Flag Pole Design, twice the above value may be used in the <br />design calculations. <br />Allowable Axial Capacitv: <br />Shaft capacity:250 psf applied below the point of fixity over the surface area <br />of the shaft. <br />Tip capacity:2,000 psf. <br />As an alternative, flag poles may be designed based on the UBC 1997, Chapter 18, <br />Section 1806.8.2. <br />New Foundation Construction (if any) <br />Based upon our observations and test data, the onsite soils are low (fill materials, upper <br />3-5 feet) to high (alluvial materials) in expansion potential. The following preliminary <br />foundation construction recommendations are presented for planning purposes: <br />1. / The minimum width for continuous wall footings supporting one-story floor loads <br /> should be 15 inches, and 18 inches for walls supporting two-story floor loads, withminimum embedment depth of 36 inches. The square column footings should be <br />at least 24 inches by 24 inches in minimum plan dimensions. <br />2. All continuous footings should be reinforced with a minimum of two No. 4 reinforcing <br /> bars at the top and two No. 4 reinforcing bars at the bottom. Square column 1 <br />\ footings should be minimally reinforced with No. 4 bars placed at 18 inches on \genter, both ways, near the bottom of the footing. <br />Pacific Development Group <br />1307 West Sunflower Avenue, Santa Ana <br />Filelse,verandree\4904976al.foundshopctr <br />GeoSoils, Inc. <br />W.O. 4976-Al-OC <br />November 2,2005 <br />Page 9
