On October 17, 2012, the Southern Pine Inspection Bureau (SPIB) announced in a letter submitted to the American Lumber Standard Committee’s (ALSC) Board of Review that it was withdrawing its submission of proposed lumber design values for the remaining grades and species of visually-graded Southern Pine (SP) lumber.
On December 12, 2012, SPIB submitted new recommendations to the ALSC regarding changes to SP design values. According to a memo from ALSC (click on the first pdf link below to view), the Board has asked the Forest Products Laboratory (FPL) to review the proposed revisions. Further, ALSC’s Board of Review will conduct a hearing at 9:00 a.m. on January 30, 2013, at the offices of Venable LLP (575 7th Street, N.W. Washington, D.C. 20004) to review SPIB’s data (click on the first through third xls links below to view the raw bending, compression and tension data) and allow all interested parties to provide input on the recommended changes.
Between now and January 1, 2013, SBCA staff is reviewing SPIB’s recommended SP design value changes and is working to update a series of roof truss, floor truss and floor joist span tables comparing the various North American lumber species for reference to its component manufacturer members.
Along with the data, SPIB submitted a summary report (click on the second pdf link below to view) that documents the results of the recent (2010-2012) tests on visually graded Southern Pine dimension lumber and establishes new design values based on these recent tests. The Southern Forest Products Association (SFPA) also issued a press release announcing SPIB’s submittal (click on the third pdf link below to view).
