OSHPD Seismic Certification Services

State of California Health and Human Services Agency

Office of Statewide Health Planning and Development

Following the 1994 Northridge Earthquake which resulted in $3 billion damage to hospitals, the State of California enacted regulations to ensure the structural integrity of structures and facilities in within the healthcare communities during a seismic event.

The State of California Health and Human Services Agency established the Office of Statewide Health Planning and Development (OSHPD) to oversee the California’s healthcare institutions and infrastructure. OSHPD provide regulatory guidance for building codes, construction, renovation and seismic safety of healthcare facilities within the state. Clark Testing’s seismic test laboratory provides OSHPD certification utilizing its tri-axial seismic shake table.

California OSHPD developed a voluntary preapproval program for seismic certification which began in 2008 and was named the OSHPD Special Seismic Certification Preapproval, or the OSHPD OSP. Clark Testing works with a number of structural engineering and consulting companies to support our customers through the preapproval process.

As called out in OSHPD requirements, Clark maintains a ISO/IEC 17025 accreditation with A2LA.

In addition to OSHPD seismic testing, Clark Testing also provides AC-156 and IBC-2015 seismic certification for manufactures selling equipment and components for use in commercial building applications. Clark’s tri-axial seismic shake table is comprised of a 10 x 10 hexagon plate operating on an independent tri-axial hydraulic system.

The Seismic table at Clark Testing is capable of performing seismic testing on large packages up to 20,000 lbs. at 1g ZPA. The table can achieve 3g’s ZPA up to 10,000 lbs. & 5g’s for lower weight. The table has three (3) independent servo hydraulic actuators with 38,000 lbs. force +/- 5” stroke with peak acceleration of 15g – 18g.
