Information and Resources on Proposed CHANGES to Southern Pine Lumber Design Values
On October 6, 2011, the Southern Pine Inspection Bureau (SPIB) announced it was submitting a proposal to the American Lumber Standard Committee’s (ALSC) Board of Review to lower the design properties for all grades and sizes of visually graded Southern Pine by 25%-30%. SPIB also indicated that it intended, upon approval by the ALSC Board of Review, to immediately implement and publish the new design values. Gary Ehrlich, NAHB’s Program Manager – Structural Codes & Standards, represents NAHB on the ALSC. NAHB has been working with members of its Building Systems Councils, the Structural Building Components Association (SBCA) and other industry representatives on this issue.
