HCAI Seismic Certification Cost — What Actually Drives It

A plain-English guide to the cost factors behind HCAI seismic certification (formerly OSHPD): OSP pre-approval, OPM listings, AC156 shake table testing, and project anchorage letters. Every project is scoped individually — request a written proposal for accurate pricing.

HCAI seismic certification — relative cost overview

The table below shows the relative level of investment for each certification path under the 2025 CBC and ASCE 7-22. Actual fees are scoped per project and provided in a written proposal — no quoted figure on this page is a price commitment.

Project anchorage letter (PE/SE stamped)Lowest investmentSingle equipment, single project, by analysis.
OPM listing (anchorage details database)Moderate investmentPer equipment family. Reusable across projects.
OSP pre-approval (analysis only)Moderate investmentPassive equipment, Ip = 1.0 or 1.5.
OSP pre-approval + AC156 shake table testHigher investmentActive equipment, Ip = 1.5. Includes test witness + cert.

What drives the cost?

  • Equipment weight, footprint, and center-of-gravity height
  • Number of model variants under one certification family
  • Active vs passive (shake table testing trigger)
  • Ip = 1.0 vs Ip = 1.5 (life-safety vs operational)
  • Mounting condition (rigid, vibration-isolated, snubbed)
  • Whether vendor drawings are stamped or sketches only

When OSP pre-approval pays for itself

A project anchorage letter is cheaper upfront, but if you sell the same chiller, generator, AHU, or medical gas skid into multiple California hospitals, OSP pre-approval eliminates per-project deferred submittals and the schedule risk that comes with them.

Many OEMs find that OSP pre-approval pays back after a handful of California hospital projects. Compare your current spend on per-project anchorage submittals against a one-time OSP fee — we can model the breakeven for your specific equipment and pipeline.

Beware of fixed-fee quotes that don't list the equipment weight or Ip assumption. Those numbers ALWAYS change scope. Our quotes itemize them.
