reports submitted to the department are representative of each shipment. 6 Ensure the provision and use of timber and lumber that has been inspected by an
American Lumber Standard Committee (ALSC) accredited third party agency before shipment, that a certificate of inspection is given to the engineer, and that each piece inspected and certified is marked accordingly; wood to be treated may be unmarked. Ensure that untreated lumber has been seasoned to a moisture content of 20 percent or less before shipment. 7 Certification or grade marking does not constitute acceptance; the engineer will reject
material not meeting specifications upon delivery. 8 Stack wood stored at the job site to ensure proper ventilation and elevated off the
ground; the engineer may reject wood damaged because of improper storage. 9 Provide rough-sawn timber or lumber in accordance with Table 817.1-1, Dimensional
Requirements: Rough-Sawn Timber or Lumber. 10 Provide posts in accordance with Subsection 816.10, Treated-Timber Sign Posts.
