Corner at Centerline = 100 <br />RECOMMENDATIONS: <br />The firm soils at the above listed elevations are suitable for the support of the <br />proposed building. It is our opinion that these soils are capable of supporting <br />footings proportioned to exert a bearing pressure of no more than 3000 pounds <br />per square foot. <br />The soft soils, . and the fill soils are not suitable and should be removed by <br />excavation from the area of the proposed building and from an oversize strip <br />around the perimeter of the building of one foot in width for every foot from the <br />footings down to the firm soil. Granular fill may then be imported and <br />compacted in layers to support the building. <br />The granular fill should consist of 100% crushed granular material meeting the <br />Minnesota Department of Transportation's Class 5 specification. The most <br />economical and suitable material for this purpose is usually recycled concrete. <br />The fill should be placed and leveled in the excavation in layers no thicker than 2 <br />feet and the surface compacted using a suitable vibratory roller until no further <br />settlement is noticeable from further passes of the roller. <br />The possibility exists that the soils could improve as you go farther west into the <br />lot and further exploration of these soils is one possiblity. <br />Page 39 <br />
