<br />2. Recommendation n Screw Anchor System <br /> <br />I) Screw Anchor System <br /> <br />A. Foundations <br /> <br />Install steel screw anchors (such as Helical Pier Foundation Systems, installed as per <br />manufactures recommendation). Foundation to be constructed of pored concrete walls with <br />steel reinforcement or with grade beams and pored concrete wall with steel reinforcement, <br />please consult a strnctural engineer fe; design. <br /> <br />B. Garage and Basement Floor Slabs <br /> <br />All Garage and Basement Floor Slabs shall be structural, concrete with steel <br />reinforcement, please consult a structural engineer for design. <br /> <br />Basement Slabs should have clearance from maximum anticipated groundwater level <br />and should be protected from intrusion by surface waters. This groundwater clearance should <br />be four feet or more from known groundwater level if the residence are to be approved by the <br />Department of Housing and Urban Development (DHUD) for FHA or V A financing. <br />According to boring evidence, groundwater was encountered and this advisory is met when <br />basement slabs are set at an elevation of98.9 feet or higher. Site grading should be controlled <br />so that no opportunity is provided for water to enter subsoils or foundation wall backfill <br />areas. <br /> <br />Please refer to the standard data sheet at the end of this report entitled "Floor Slab <br />Moisture/Vapor Protection". <br /> <br />3. SidewaIklExterior Building Backfill <br /> <br />A minimum on feet of engineered fill, properly oversized and compacted, should be <br />placed below exterior sidewalks and compacted to a minimum of 95% of Standard Proctor <br />density. Other recommendations relative to backfilling the structure and placing fill below <br />exterior slabs appears on the standard data sheets at the end of this report. These sheets are <br />entitled: <br /> <br />. Basement/Retaining Wall Backfill and Water Control <br /> <br />. Freezing Weather Effects on Building Construction <br /> <br />These sheets present information on preferred soil types, frost considerations, <br />drainage, and lateral pressures. The first data sheet also provides information on lateral eat1h <br />pressures for design of exterior retaining walls. <br /> <br /> <br />3 <br />
