Hensolt SEAONC Legacy Project

In 2014, SEAONC received a generous donation from the family of Walter Hensolt. In honor of this donation, the SEAONC Board of Directors approved an initiative in 2015 to create the Hensolt SEAONC Legacy Project. The purpose of the Hensolt SEAONC Legacy Project is to establish a continually expanding interactive online database of the history of structural engineering in Northern California, featuring stories and backgrounds on the engineers, structures, organizations and events that have shaped the structural engineering profession in the San Francisco Bay Area.

Our committee is proud to announce that after three years of research, design and hard work by SEAONC committee volunteers, the project has been launched and may be viewed at https://legacy.seaonc.org.


SEAONC is proud to be part of both the Structural Engineers Association of California (SEAOC) and the National Council of Structural Engineers Association (NCSEA)
