code-assigned Risk Category for a typical data center is II; mission-critical owners often elect RC III/IV seismic performance (importance factor, operability) as an owner requirement, not a code mandate
RC II code / III–IV electiveobserved
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | Code minimum for an ordinary data center building. A facility designated as an emergency preparedness, communications or operations center, or otherwise required for emergency response, is Risk Category IV by code. Risk Category III or IV performance for a commercial data center is an owner requirement the design team must be asked, and funded, to meet. |
