1795 Fox Street July 14, 2017 <br /> Project#: 11767.17.MNS Page-6 <br /> F.3. Groundwater <br /> As mentioned earlier,water was not observed and appears to be below the depth explored by the borings. <br /> G. General Grading Recommendations <br /> G.1. Stripping and Excavation <br /> The surface stripping operations can likely be accomplished with either tired or tracked equipment. A <br /> backhoe with a smooth-lipped bucket is recommended for deep excavations. <br /> G.2. Compaction <br /> All fill should be placed in lifts adjusted to the compactor being used and the material being compacted. We <br /> recommend limiting lifts to no more than 1-foot—assuming large, self-propelled or tow-behind compactors <br /> are used. Thinner lifts would be required for smaller compaction equipment. <br /> If the earthwork occurs during freezing temperatures,good winter construction practices should be used. No <br /> frozen fill should be used nor should structural filling take place on frozen ground. <br /> G.3. Construction Testing and Documentation <br /> We assume the local building official would review the bearing conditions at the time of their inspections. <br /> Fill placed below building should be evaluated for conformance to the project gradation recommendations <br /> and should be tested for compaction. If the filling proceeds during periods of freezing weather, full-time <br /> testing should be considered to help confirm that imported fill is thawed prior to and during compaction,and <br /> that all snow has been removed before placement of the fill. <br /> H. Level of Care <br /> The services provided for this project have been conducted in a manner consistent with that level of care and <br /> skill ordinarily exercised by members of the profession currently practicing in this area, under similar budget <br /> and time constraints. This is our professional responsibility. No other warranty, expressed or implied, is <br /> made. <br /> MINNESOTA IOWA WISCONSIN <br />
