m <br />i <br />REPORT OF SUBSURFACE EXPLORATION PROGRAM <br />PROPOSED PILLSBURY RESIDENCE <br />ORONO, MINNESOTA <br />#120 86-74 <br />INTRODUCTION <br />W® und®fstind the proposed construction will consist of a two-story, wood-frame <br />house with a detached garage. An on-site sewage treatment system will also <br />be constructed. <br />In accordance with your verbal authorization on April 12, 1985, we have con­ <br />ducted a subsurface exploration program for the proposed construction. The <br />scope of our work on this project is as follows: <br />1. Provide recommended foundation types and depths, <br />allowable soil bearing pressures and estimates <br />of settlement. <br />2. Provide recommendations for site preparation for <br />support of the foundations and floor slab. <br />3. Perform percolation tests and provide recanmen- <br />dations for construction of an on-site sewage <br />treatment system. <br />Our work program for accomplishment of the above objectives Included three <br />standard penetration soil test borings, nine auger borings, six percolitioii <br />tests. I few laboratory tests and observation of the recovered soil saniplet.
