Engineering & Testing


Three experts argue for using advanced building systems to meet new standards and reduce overall costs.

SBCA has created a complete 2x4 through 2x12 Southern Pine lumber blind substitution chart for component manufacturers to use in preparation for the September 1, 2012 deadline.

Lumber suppliers serving and supporting the best interests of lumber buyers is a very significant development. SBCA Executive Director Kirk Grundahl shares a recent email exchange he had with SFPA President Adrian Blocker.

It appears the innovative Audited Stress Rating (ASR) program proposed by Timber Products has hit the end of the line.

 Looking through old issues of Wood Words Magazine (SBC Magazine’s predecessor), you can’t help but feel a sense of déjà vu when reading this article from August 1991 regarding lumber design values.

On Saturday, March 31, 2012, SBCA sent a letter to the American Lumber Standards Committee (ALSC), requesting further information on lumber design value testing currently being conducted on North American softwood lumber species.

The High-Performance Building Congressional Caucus Coalition held a briefing on Capitol Hill this past Thursday.

The SBCA SP lumber substitution chart was created to help buyers and suppliers ascertain the lumber design values that are direct substitutes for visual and MSR/MEL grades using all species groups for 2x4 lumber.

On Friday, ALSC ruled to approve SPIB’s proposed design value reductions for SP 2x4 No. 2 Dense and SP 2x4 No. 2 Non-Dense.

A proposal submitted by Timber Products Inspection that would use visual grading to assure lumber design values was rejected by ALSC.
