.Page 2 of 4 <br /> <br />Report No. NER-481 <br /> <br />2, Actual design stresses do not exceed the allowable design stresses <br /> noted in Table No, I of this report. <br />3, StructuFal ca~culatiof~s and drawings verifTing compliance with <br /> this report and the applicable code are submitted to the authority <br /> having jurisdiction. Such documents shall be signed and sealed by <br /> a registered design professional, when required by the applicable <br /> code, state or local statutes, <br /> <br />4. TimberStrand LSL shall not be used where a maximum moisture <br /> content exceeding 19 percent will result. <br />5, Duration of toad adjustments, as provided for wood members and <br /> their connections, are permitted in accordance with the limitations <br /> specified in the applicable code. <br />6.
