Continuous (strip-shaped) ( foundations will be up to 2 feet wide and isolated (square-shaped) foundations will be up to 7 feet wide. Net foundation bearing pressure will be designed for up to 2000 pounds per square foot (psfl loading. � I • The building interior will be permanently heated and not subject to freezing during its life. The garage and garage floor slab may be subject to freezing during the building life: SITE CONDITION The project site is a lot of land at 701 Dickey Lake Drive in Orono, Minnesota. The lot is vacant with grass, brush and tree covering. Relief across the lot is relatively flat, with a shallow depth drainage swale situated parallel with and along the north edge of Dickey Lake Drive opposite the lot. A large natural wetland lies a few blocks northeast of the lot, and its water surface appears to be nearly 20 feet lower than the site. This surface is a manifestation of the ground water level in this area. A smaller naturai wetland lies neariy one-half mile northwest of the lot, and it appears to be on the order of 20 feet lower than this lot. The water surface of this smaller wetland is an indicator of the ground water level in this area. SUBSURFACE EXPLORATION The client selected locations of two e�loratory soil borings on the lot. These locations roughly coincide with the front and rear lines of the buildable area of the lot. Allied drilled two borings at the selected locations. Borings 1'and 2 were drilled respectively near the front and rear lines thereof. Borings are shown on the Boring Location Plan in Appendix A. Allied measured ground surface elevations at the borings using a temporary benchmark (TBM) with an assumed elevation of 100 feet The TBM is on the centerline of Dickey Lake Drive opposite the lot. Elevations are noted on the Boring Logs in Appendix B. Accuracy of the boring locations and elevations should be considered with respect to the methods used in their establishment. Borings were drilled to depths indicated on Boring Logs in Appendix 8. Borings were drilled with hollow stem augers on dates indicated on the boring logs using a truck- mounted CME-55 drill rig. Standard Penetration (SP'T� testing was used to obtain soil specimens and N values. A specimen was obtained by driving the SPT sampler 1.5 feet into the bottom of the boring according to ASTM D1586 (Penetration Test and Splif-Barr�l Samp/ing of Soin. The sampler interval is noted as SS on the Boring Logs in Appendix B along with its N value. The N value is the number of SPT hammer blows needed to drive the sampler 12 inches into the bottom of the boring. Grab specimens of soil from auger cuttings are noted on the Boring Logs. Soil specimens were sealed and labeled in glass jars for subsequent review and classification. Allied Projed 05039 2 July 31, 2005
