In response to recommendations by the Southern Pine Inspection Bureau (SPIB) proposing a reduction in some building standards to which Southern pine can officially be expected to perform, the National Frame Building Association on November 15th, 2011 submitted the following recommendations to the American Lumber Standards Committee (ALSC).

"The National Frame Building Association (NFBA) strongly recommends that structural design property changes resulting from the American Lumber Standards Committee (ALSC) changes in the southern pine wood resource be addressed by changing the visually stress rated lumber grading rules rather than by drastically changing the currently published reference design strength of visually stress rated southern pine lumber. The NFBA suggested approach would result in much less confusion, both during the transitional phase of the proposed changes and in the long term, within the entire building supplier and design community. NFBA also thinks the likelihood of significant design and/or construction errors would be greatly reduced by adoption of the NFBA recommendation.

Whichever approach is finally adopted for addressing the changes in the structural performance of the current southern pine resource, NFBA urges the wood industry to minimize the impact of the changes on the wood construction industry. If changes are necessary, NFBA will strongly petition for clear identification of the applicable design strength, minimal need to conduct secondary visual grading of southern pine wood resources in inventory and a transition period defined and owned by the lumber industry to allow the entire construction market to adjust systematically rather than chaotically."

NFBA shared the above recommendations in a letter to SPIB, which can be viewed by clicking the pdf link below.
