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.
| Service | Relative Investment | Notes |
|---|---|---|
| Project anchorage letter (PE/SE stamped) | Lowest investment | Single equipment, single project, by analysis. |
| OPM listing (anchorage details database) | Moderate investment | Per equipment family. Reusable across projects. |
| OSP pre-approval (analysis only) | Moderate investment | Passive equipment, Ip = 1.0 or 1.5. |
| OSP pre-approval + AC156 shake table test | Higher investment | Active equipment, Ip = 1.5. Includes test witness + cert. |
| AC156 shake table testing only | Varies by lab + equipment | Lab fees vary by equipment weight + frequency content. |
| IBC §13.2.2 certification (non-CA projects) | Scoped per project | Nationwide, no HCAI submittal required. |

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.
