Our Passion for Resiliency: Based in New York City, we understand resilience – the ability to rebound, respond, recover and prepare again – at a multi-hazard level with experience in seismic, wind, flood, snow, blast and progressive collapse hazards. GMS has helped to draft codes and standards to improve the resilience of buildings and infrastructure across the country, even before New York City adopted its first seismic code provisions. The USRC rating system will help the public better understand the choices that we, as a society, make and help improve building performance in the future.
