AWC Publishes 2027 SDPWS Standard With New Seismic Wood Systems
Leesburg, Va. – September 24, 2026 -- The American Wood Council (AWC) has published the 2027 edition of the Special Design Provisions for Wind and Seismic (ANSI/AWC SDPWS-2027), adding two new construction systems for engineers designing in high-hazard wind and seismic zones. The standard has been approved as an American National Standard by the American National Standards Institute (ANSI) and will be referenced in the 2027 I-Codes.
Five-year technical process yields ANSI approval after 13 balloting rounds
The 2027 SDPWS resulted from five years of technical development and two years of balloting under ANSI's consensus-based process, including 13 rounds of balloting and a full public review period. SDPWS is typically updated every six years to keep pace with new research and align with other design references.
