319.1 Basis for Evaluation and Design
This section determines what technical approach is to be used for the seismic evaluation and design for existing buildings. For those buildings or portions of buildings for which Section 317 requires action, the procedures and limitations for the evaluation of existing buildings and design of retrofit systems and/or repair thereof shall be implemented in accordance with this section.
One of the following approaches must be used:
- Method A of Section 320;
- Method B of Section 321, with independent review of a peer reviewer as required in Section 322; or
- For state-owned buildings only, the use of one of the specific procedures listed in Section 319.1.1.
When Method B is chosen it must be approved by the building official, and, where applicable, by the peer reviewer. All referenced standards in ASCE 41 shall be replaced by referenced standards listed in Chapter 35 of the California Building Code.
- [BSC] For buildings constructed to the requirements of California Building Code, 2013 or later edition, as adopted by the governing jurisdiction, that code is permitted to be used in place of those specified in Section 319.1.
- [DSA-SS & DSA-SS/CC] For public schools and community colleges constructed to the requirements of California Building Code, 2013 or later edition, that code is permitted to be used in place of those specified in Section 319.1 provided the building complies with Seismic Design Category D or higher.
[BSC] For state-owned buildings, the following specific procedures located in Appendix A may be used, without peer review, for their respective types of construction to comply with the seismic performance requirements for Risk Category I, II or III buildings:
