H. Dahlmeier Engineering Inc. has been retained to provide a structural engineering review of the <br /> foundation system under construction for the garage structure to be constructed at 1130 North Shore <br /> Drive, Orono, MN as directed by Walter Holzer, owner of the property. <br /> BACKGROUND <br /> Walter Holzer intends to construct a garage structure Group M occupancy. <br /> The City of Orono Building Inspections Department requires a structural engineering review of the <br /> foundation construction. <br /> OBSERVATIONS AND COMMENTS <br /> 1. Drawings for the structure include six sheets dated 2/24/97, Plan No. C103056, prepared by <br /> Minnetonka Design, Inc. A copy of the roof truss design has been furnished to me. The <br /> foundation layout using a thickened slab edge has been Frovided to me. The structure will be 30' <br /> x 33' with a storage space in the attic space within the roof truss system. Thickened slab method <br /> is being used instead of the full depth footings and foundation wall shown on the drawings. <br /> 2. The thickened slab concrete foundation system consists of a 4" thick slab with a thickened edge <br /> 12" deep and 12" wide and tapered at a 45 degree angle up to the slab thickness on all four <br /> perimeter sides with two#4 running the long direction and three#4 running the short direction in <br /> the slab. <br /> 3. The thickened slab has two #4 bars stacked the entire perimeter of the building. A 4" starter <br /> course will be placed on top of the 12"thick slab for construction of the frame structure. <br /> 2434 Commerce Boulevard 0 Mound, MN 55364 0 (612) 472-4746 0 FAx (612) 472-4761 <br />
