<br />e <br /> <br />e <br /> <br />e <br /> <br />t111'&/J/x H-I <br /> <br />PRELIMINARY GEOTECHNICAL EXPLORATION <br />AND REVIEW <br />FOR <br />GATEWAY BUSINESS CENTER <br />35W /694 <br />ARDEN HILLS, MINNESOTA <br /> <br />AET #01-00578 <br /> <br />SUMMARY <br /> <br />Purpose <br />It is proposed to construct the three building Gateway Business Center at the NE quadrant of <br />35W/694 in Arden Hills, Minnesota. The purpose of our work on this project is to explore <br />subsurface eonditions and provide preliminary geotechnical engineering reeommendations to assist <br />you and the projeet team in planning, design, and construetion. <br /> <br />Scope <br />To accomplish the above purpose, you have authorized our finn to drill twelve (12) test borings <br />at the site, condnct laboratory testing, and prepare this geotechnical engineering report. <br /> <br />Findings <br />The test borings indicate a generalized soil profile of I' to 14' of fill, topsoil and swamp deposits, <br />underlain by glacial till and alluvial soils. Ground water was present at some of the borings at <br />depths varying from about 7' to II'h' below existing site grade. <br /> <br />Recommendations <br />These reeommendations are eondensed for your convenience. Study our entire report for detailed <br />recommendations. <br /> <br />. <br /> <br />. <br /> <br />Th~ proposed office buildings can be supported on spread footing foundations ,designed for <br />an allowable bearing pressure of 3,000 psf to 4,000 psf after soil correction. <br />The ~ilJ:orreetion should include removing the surfieial fill, topsoil, swamp deposits, and <br />softer (N,;5 bpf) clayey soils. <br />The floor slab can be su rted on ade after erforming the soil eorrection. <br />AlternatIve y, e proposed five story office building can be support on a pile <br />foundation, if foundations designed for a 4,000 psf bearing pressure are not practical. <br />Perimeter draintile shonld be installed around below grade building space. <br />Pavements can be supported on the non-organie site soils after surface compaction and <br />pJaeement of compacted fiIJ to reattain plan grade. Soils which become unstable during the <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br />
