With all interior load bearing walls and columns removed from the design before <br /> cons#ruction began, the perimeter footings are carrying most of the struetures load. The interior <br /> walls, furnishings and appliances average less than 100 pounds per square foot. The 4" concrete <br /> slab will weigh 50 pounds per square foot and the two automobiles will produce eight spot loads of <br /> 1000 pounds per square foot. The maximum bearing pressure at the building pad will be 1150 <br /> pounds per square foot. This will dissipate to approximately 165 pounds per at the 6 foot depth <br /> of the silty clayey soils_ At other sites along North Shore Drive our drill rig has encountered <br /> bearing pressures of 1300 pounds per square foot in the silty clayey soils at and below the <br /> water level. This is eight times greater than the cafculated bearing pressure at the subject <br /> site, which gives a large factor of safety and a great comfort zone for proceeding. <br /> (2) A Dynamic Cone Pentvmeter (DCP)*was applied to the interior soils on site. Explained in more <br /> detail below this device is very effective in determining the 'in place' strength of soils_ The sands <br /> to a depth of 4 feet were abserved to be sofid fill materials and the test results bear this out (3500 <br /> pounds per square foot). We were no#able to get to get deeper to the clayey silts at 6 feet as the <br /> soils were too tight and cold to allow penetration of the measuring device. <br /> � <br /> " 7he DCP Is an objective test to confrm soil st�ength. A cone at the end of a metat rod is driven into the soil by <br /> a 17.2 pound weight falling 0.5 mete�s, The resultant millim�ers per blow can be conv�rted to the <br /> cem�monly used pounds per square foot. <br /> _ � <br /> R'eported By: Date: Dec. 8, 2003 <br /> �� <br /> Daniel .
