We would <br /> consider the footing design of 20" R 10" acceptable for the <br /> proposed construction, but would recommend the addition of 2 - #5 <br /> reinforcement .rods . The reinforccment may be crossed at the corners, <br /> with splices were required at a minimum 36 bar diameters . � <br /> our observations and subsequent soil evaluation on this date are <br /> Iimited in scope to soil conditions abserved within li.mited sections <br /> of the footinq excavation and to depths achieved by shallow probes <br /> and a dynamic cone penetrometer test. We therefore, are unable to <br /> assess soil condi•;.ions at depths which may be encountered by soil <br /> borinqs conducted as part of a standard subsurface geotechnical <br /> investigation. <br /> Sincerely, <br /> Insta ' ng Company <br /> � � <br /> a y ta i Dennis Odens , P.E. <br /> spector ' <br /> CC: City of Orono uildinq Inspections <br /> , #701 - 1 / #605 1 1/4 / #304 - DCP {1) / #612 - 52 <br /> FINNEYMK.DOC <br />
