Verdantas provides comprehensive geotechnical and geologic support for performance-based seismic design (PBSD), integrating advanced site characterization, seismic hazard analysis, and ground motion development to support soil–structure interaction evaluation and enable structural designs that achieve defined seismic performance objectives rather than relying solely on prescriptive code provisions. The practice includes engineers with expertise in numerical modelling, vibration analysis, seismic hazard evaluation and mitigation across critical infrastructure facilities including bridges, dams, piers, buildings, roadways, tunnels, and power plants, as well as experience in characterization of subsurface material static and dynamic properties, liquefaction evaluation, landslides, site response analysis, seismic hazard analysis, and ground motion characterization.
When applied particularly in high-rise building design, PBSD ground motion studies can result in significant reduction in construction cost by eliminating the amount of concrete and rebar used in construction. Additional advantages include:
- More reliable attainment of intended seismic performance
- Elimination of some code prescriptive design requirements
- Accommodation of architectural features that may not otherwise be attainable
- Use of innovative structural systems
These benefits make PBSD a valuable tool for owners, developers, and design teams seeking to optimize structural investment while achieving reliable seismic resilience.
