SUBSURFACE EXPLORATION <br /> LOT 2, BLOCK 1 <br /> KELLY 2nd ADDITION <br /> ORONO, MINNESOTA <br /> ALLIED No. 94117 <br /> vary hoth seasonally ar,.: annually and with changes in rainfall and runoff patterns :;s well as <br /> other conditions in the local area. <br /> Attached are the logs for each of the test boring locations presenting the compl�te r�.�sults <br /> of the field exploration. The depth of individual layers of soil, (at and in between the bc�ring <br /> locations), may vary somewhat from those indicated on the logs due to the occunenr,�� of <br /> transitions between soil layers, intervals not sampletl, and the natural variability af th� soil <br /> formations. <br /> CONCLUSIONS AND RECOMt��NDATIONS <br /> The results of test borings indicate the presence of fill, soft and organic soils. T}�es:� soils <br /> would not be suitable for the support of the residence by a conventional spread footing <br /> foundation system. Excavation of these unsuitable materials and replacement with a c;ont:olled <br /> and compacted fill would be very difficult to accomplish, due to the presence of groundwater <br /> among other factors, and would not be recommended as a means to provide support for the <br /> plannetl residence. It should be possible to provide support for the residence using timber piles <br /> which woul;� transfer loads to the underlying inorganic, sdff to very stiff clay soils. These piles <br /> would derive their capacity from a combination of end bearing and side friction. Additiona` <br /> recommendations are presented in the following sections: <br /> l. TIMBER PILING <br /> For best results, we recommend that the residence be supported on a deep foundation <br /> system consisting of driven, timber piles. The garage and lower floor slab should also be <br /> supported on the piles. For timber piling, we anticipate that as much as 15 tons of potential <br /> 5 <br />
