Included with this letter are the report and <br /> calculations. We did the calculations in accordance with the 2012 IBC, ASCE 7-10, <br /> 2012 NDS, and guidelines stated in the Solar America Board for Codes and <br /> Standards. <br /> n g i n e e r Some of the components in the SnapNrack test data were used to determine the <br /> capacity and section properties of materials. We collected the test data using the <br /> so22 sun�ise at�d procedures outlined in the 2012 IBC Chapter I7. <br /> Fair Oaks,CA 95628 <br /> (916)536-9555 <br /> (916)536-0260(fax) We included the following types of load combinations and building parameters into <br /> our calculations: <br /> 1989-2013 <br /> Z4 years ojercellence .
