Page 8 - # 20-10689 <br />In preparation for construction all existing fill, swamp deposits and <br />soft alluvial clays should be excavated in the proposed building area. <br />In addition, the upper portion of the glacial till soils encountered in <br />some areas of the site were sumewhat softer and will also require <br />excavating for support of 5000 psf footing loads. The estimated depth <br />of excavation required for floor slab support and also the elevations <br />suitable for an allowable bearing pressure of 5000 psf are indicated in <br />the following table: <br />Elevation of <br />Boring <br />-No. <br />Surface <br />Elevation of <br />otttom o=xcavation <br />el vat1on <br />5UO0 psf Soil <br />For 1oor lab upport <br />1-83 <br />96.7' <br />84.7'-,y. <br />89.7' <br />2-83 <br />85.6' <br />76.1' - �' <br />76.1' <br />3-83 <br />87.2�' <br />75.2' _ , <br />81.2' <br />4-83 <br />97.3' <br />94.3' _ 3 <br />94.3' <br />5-83 <br />86.9' <br />-- <br />82.9' <br />6-83 <br />85.0' <br />-- <br />Below elevation /0.0' <br />The elevationsindicated in the table above are based on the soil <br />conditions encountered at the boring locations. These elevations may <br />vary 'between boring locations or be different in other areas of this <br />site. The required depth of excavation should therefore be determined <br />in the field at the time of construction. <br />SOIL exPLORBtion <br />
