Forell/Elsesser continues to lead the field in providing a diverse range of engineering services to achieve IBC/CBC certification equipment, including OSHPD OSP and OPM pre-certification. Our team is available to guide you through the steps of shake table testing and Special Certification. Our extensive experience with obtaining certifications and OSP’s for a wide range of manufacturers and equipment types allows us to streamline the process and develop testing plans which can minimize the number of tested units while maximizing the range of certified units. If seismic certification testing is new to you, we have enduring relationships with numerous shake table facilities around the country which are able to perform tests to the required AC 156 standards.
Forell/Elsesser was among the first engineering firms to achieve special seismic pre-certifications of mechanical and electrical equipment. Having a strong, long-standing, and close relationship with OSHPD officials has allowed Forell/Elsesser’s Seismic Pre-Certification team to remain at the forefront of this emerging market.
Seismic certification is rapidly gaining importance in today’s performance-based design environment. Seismic certification has clear applications beyond healthcare and beyond California, including emergency operations centers, schools, data centers, and critical manufacturing facilities.
Shake table testing for specific equipment installations including configurations with sliding seismic isolators is a service we provide as shown in the videos below. These tests were performed at the Richmond Field Station test facility under the direction of Forell/Elsesser and EQX Global (www.eqxglobal.net) to compare the performance of standard computer server installations with the improved performance provided by local seismic isolation.
