Performance Based Seismic Design is part of NYA’s foundation. In the early 1990s, our founder, Nabih Youssef, helped write Vision 2000. This key document shaped what PBSD is today.
Building a Legacy of Leadership
Since then, NYA has helped shape national PBSD standards. Our team worked on the PEER Tall Buildings Initiative and guidelines for cities like Los Angeles and San Francisco. We also contributed to major updates to the ASCE 7 standard.
Real Value for Clients
Our history in PBSD means we understand how buildings behave during big earthquakes. We’ve used these methods on hospitals, high-rises, civic buildings, and essential services. As a result, clients gain safety, value, and design flexibility.
We Combine Innovation and Experience
At NYA, we don’t just follow the rules—we help write them. We’re leaders in seismic systems like base isolation, fluid viscous dampers, and steel plate shear walls. In fact, we authored many of the standards engineers use today.
Trusted by Cities and Partners
Because of our deep experience, major cities trust us as PBSD peer reviewers. Moreover, we work closely with owners, architects, and design teams to deliver stronger, safer buildings.
Performance Based Seismic Design gives your team more control and better results. NYA brings deep knowledge and proven systems to every project. With us, your buildings meet high standards—and go beyond them.
Advanced Seismic Solutions and Peer Review Leadership
We are nationally recognized for our use of advanced seismic systems such as base isolation, fluid viscous dampers, and steel plate shear walls. Moreover, NYA authored the standards now embedded in code and routinely serves as on-call PBSD peer reviewers for multiple West Coast jurisdictions.
At NYA, Performance Based Seismic Design is not just a service offering, it is part of our history. In the early 1990s, our founder, Nabih Youssef, co-authored Vision 2000, the seminal document that established the foundation for modern PBSD.
Building on that legacy, NYA has played a key role in shaping the national standards and guidelines that define PBSD today. Our engineers have contributed to the development of the PEER Tall Buildings Initiative, the Los Angeles Tall Buildings Structural Design Council Guidelines, San Francisco’s Requirements and Guidelines for Non-Prescriptive Tall Building Design, and updates to the ASCE 7 standard.
This legacy translates directly into value for our clients. NYA brings unmatched insight into how buildings perform in major earthquakes, backed by decades of applying PBSD on hospitals, mixed-use towers, civic facilities, and essential service buildings in the most demanding seismic regions.
We pair deep code-defining expertise with innovation. NYA is a national leader in advanced seismic systems, including base isolation, fluid viscous damping, and steel plate shear walls and authored the design standards that form the basis of today’s code requirements. We are also trusted as on-call PBSD peer reviewers for several major West Coast jurisdictions.
For owners, architects, and project teams, this means greater design flexibility, clearer performance outcomes, and safer, more resilient buildings. With NYA, you’re partnering with engineers who helped create PBSD and continue to advance what’s possible with performance-driven seismic design.
