SUBSURFACE EXPLORATION <br /> LOT 2, BLOCK 1 <br /> KELLY 2nd ADDITION <br /> ORONO, MINNESOTA <br /> ALLIED No. 94117 <br /> areas, (such as backfill zones, utility trenches and in detail areas), "smooth plate" type vibratory <br /> compactors, in combination with 6 to 8 inch maximum loose lifts should be utilized. A <br /> representadve number of field density tests should also be performed to document the <br /> effectiveness of the fill placement and compaction work. Field density tests should be performed <br /> at a minimum rate of one test for each two feet of fill installed in a given area. <br /> Since the pavements and exterior slabs, such as sidewalks, will not be supported by the <br /> deep foundadon system, some settlement would be anticipated. In these areas, a minimum subcut <br /> of three feet and refilling with granular material is recommended. Loose laid pavers might be <br /> considered in order to accommodate movements and facilitate any repairs which might become <br /> necessary. � <br /> To provide for the adequate distribution of loads, the top of any fill supporting these <br /> elements should extend at least one foot horizontally beyond the edge of the slab or footing. The <br /> fill surface should then extend downward and outward on a 1:1 slope to competent soil. If the <br /> fill slope is unconfined by other soils, the downward and outward slope should be flattened and <br /> stabilized. Also, no unremerlied, (uncompacted), excavations for utilities or other purposes <br /> should be carried out within the oversize areas. <br /> 3. FINAL SITE TOPOGRAPHY <br /> The final soil surface at the exterior of the residence should be graded to provide positive <br /> drainage away from building, sidewalks and pavements. Compliance with this building code <br /> requirement will aid in accommodating some subsidence of the landscaped ground surface at the <br /> perimeter of the residence which might be anticipated. <br /> 8 <br />
