/ <br /><E> <br />Test pit 14 was 7 feet deep, and encountered 2* of <br />sandy clay (fill) overlying 1' of black organic silt with roots, <br />2' of brown grey medium to coarse silty sand, emd 2* of sandy <br />clay, tough. <br />Test Pit #5 was 8 feet deep and encountered u feet of <br />sandy clay (fill) overlying 1 foot black organic sandy silt <br />1 foot silty sand and sandy clay. <br />It was recommended that the organic sandy silt material <br />exposed at test pits 3,4 and 5 be removed down to suitable <br />inorganic soil. This organic material is present in the east <br />and central portions of the building area and extends to depth <br />of 2-4 feet below footing grade. <br />A decision was made between the contractor emd owner to <br />excavate this material with a tracscavtor and then import fill tc <br />design footing grade. <br />The footing foundation plan for this structure indicated <br />that re-bar was not going to be used in the footings. We recommer <br />ded that 2#5 re-bars, continuous, be used. This recommendation <br />was accepted by the owner. <br />It was also recommended that soil borings be taken in <br />proposed adjacent buildings to better determine the extent of the <br />organic material and overlying fill. This knowledge would help <br />expidite the future construction process. <br />SUBTERRANEAN <br />ENGINEERING INC. <br />MINNEAPOLIS. MINN.A
