Committee Updates
In 2021, the Committee developed a position paper which was endorsed by vote of the SEAC membership. The paper encourages the use of a minimum of Seismic Design Category B for Risk Category II and higher buildings.

Position Statement on Seismic Safety

As in prior code cycles we will vote as a Professional Organization on the NEHRP code provisions developed by the Building Seismic Safety Council Provisions Update Committee (PUC). The PUC is developing the 2026 NEHRP Recommended Seismic Provisions as part of the  ASCE 7 code cycle. The balloting will start this year, 2024.
The SEAC Seismic Committee also assists the City and County of Denver in adoption of the  International Building Code with Denver Amendments. The SEAC Building Department Committee will facilitate this process and obtain input from the SEAC Seismic Committee. The next cycle should start in 2024.
