Roof: 40 PSF live load (snow surcharge per Minnesota <br /> code). <br /> Roofing dead load assumed 3 PSF (Wood Shingles). <br /> Assumed roof total design dead load 20 PSF. <br /> B. Floor: Ground Floor: 50 PSF live load or 2000#/20in2� <br /> Assumed floor total design dead load 102 PSF. <br /> Main Floor: 40 PSF live load. Assumed total design <br /> dead load 20 PSF. <br /> C. Lateral: Earth - Typical cohesionless soil pressure assumed. � <br /> Wind - Per Uniform Building Code, latest adopted <br /> edition. Basic wind speed - 80 MPH. <br /> Exposure C. <br /> SOIL PREPARATION AND FOUNDATIONS <br /> A. Materials <br /> 1. Footings to bear on properly compacted fill or native <br /> soil capable of sustaining an assumed bearing pressure of <br /> 2000 PSF in accordance with 1997 UBC Section 1805 <br /> (Class 3 material or better). Allowable bearing pressure to <br /> be verified by an independent testing agency. If soil <br /> appears to be of questionable quality or in a loose state, <br /> contact Engineer before proceeding with the work. <br /> 2. All fill material to be granular soil or other <br /> cohesionless material approved by the soil testing <br /> agency. <br /> 3. Provide 4" granular subbase under slabs-on-grade , <br /> B. Installation Notes <br /> 1. Prior to installing foundations, soil to be field inspected <br /> by an independent testing agency familiar with the site to <br /> assure that the compaction specifications have been satisfied. <br /> . Submit all inspection reports, material test reports, etc_ to <br /> the Architect. <br /> 2. All topsoil is to be stripped from building and pavement <br /> areas. All very loose sands and silt and clay soils also to <br /> be stripped. <br /> 3. All fill material to be spread in maximum 6" loose lifts <br /> and compacted with vibratory compactors to a minimum <br /> 98% of the maximum dry density as determined by ASTM <br /> D698, Standard Proctor. Moisture content at the time of <br /> compaction should be controlled to within +/- 3% of the <br /> optimum moisture content. <br /> , 4. Provide minimum 3'-6" soil cover for foundation frost <br />
