A Commitment to Ethics, Equity, Diversity, and Inclusion

As structural engineers, we frame our contributions to society through our professionalism and ethics in the duties we perform. In our practice, we serve society and are active participants in the fabric of the communities in which we live. As structural engineers, we cannot limit ourselves to solving only problems of science and engineering. Ignoring the social, economic, and political contexts surrounding our engineering work is a path to irrelevancy. Our active participation includes a moral obligation to right the social and ethical wrongs we observe.

Therefore, as part of our active strategic planning process, we will critically examine the ethical values, equity, and diversity present in our internal processes and practices related to our staff, clients, and consultants.  Please read our full statement here.

ATC/USGS Seismic Hazard User-Needs Workshop

On September 21-22, 2015, in Menlo Park, California, the Applied Technology Council (ATC) and U.S. Geological Survey (USGS) convened the ATC/USGS Seismic Hazard User-Needs Workshop. Like the ATC-35/USGS National Earthquake Ground Motion Mapping Workshops, which were held in 1995, 2001, and 2006, this User-Needs Workshop provided an opportunity for individuals and groups that use the National Seismic Hazard Maps to provide feedback on existing and planned hazard information and products from the USGS National Seismic Hazard Mapping Project.

Agenda.  The Workshop Agenda is available here.


Workshop Program.‎ The ATC/USGS Seismic Hazard User-Needs Workshop was organized to (1) elicit feedback from users of seismic hazard information and products, (2) provide a forum for the wider earthquake engineering community to discuss the transfer of seismic hazard results into engineering practice, seismic risk analysis, and public policy, and (3) make practical recommendations to the USGS National Seismic Hazard Mapping Project.

The User-Needs Workshop included presentations from invited speakers and workshop attendees:
▪ Representatives of the National Seismic Hazard Mapping Project described the changes in the 2014 update of the National Seismic Hazard Maps, including changes to the hazard model input, the calculation of hazard, and the resulting differences in hazard values. The representatives also provided an overview of seismic hazard information and products currently available at the Project website.
▪ Representatives of user groups described how they use hazard information from the National Seismic Hazard Mapping Project. Users also provided feedback on the hazard products that they currently use and ideas about development of additional products or the consolidation of existing products.

Location. William Rambo Auditorium, U.S. Geological Survey, 345 Middlefield Road, Menlo Park, California.
