Serving Los Angeles County
Seismic Engineer in Los Angeles
ASCE 7-22 nonstructural anchorage, HCAI/OSHPD preapprovals, and AC156 shake table testing — for LA hospitals, data centers, labs, and critical facilities. Stamped by California-licensed PE/SE engineers.
California-Licensed Seismic & Structural Engineers
From our office in Arcadia — inside Los Angeles County — we support manufacturers, mechanical contractors, design-build teams, and facility owners across the LA metro on the seismic compliance work that’s hardest to get right: nonstructural anchorage to ASCE 7-22, HCAI/OSHPD preapprovals, and AC156-conforming shake table testing.
PE/SE-stamped seismic anchorage calculations to ASCE 7-22 Chapter 13 for mechanical, electrical, and plumbing equipment installed at LA-area hospitals, labs, and tenant improvements. Submittals reviewed and accepted by LADBS and HCAI plan checkers.
Manufacturer preapproval support for equipment going into California hospital and skilled nursing projects — including OSP special seismic certification per CBC §1705A.13 and OPM listings under HCAI PIN 62/68.
Test plan development, AC156 RRS calculations, and witness/peer-review services at independent LA-area testing labs. Reports formatted for HCAI OSP submittal.
Walkthrough assessments and prioritized mitigation reports for existing LA facilities — schools, healthcare, data centers, and government buildings — using the FEMA E-74 framework.

Frequently Asked Questions — LA Seismic Engineering
Do you handle LADBS submittals for seismic anchorage?+
Yes. We routinely produce PE/SE-stamped anchorage calculations and details that are submitted to the Los Angeles Department of Building and Safety (LADBS) under the California Building Code (CBC), which adopts ASCE 7-22 by reference. Our packages are formatted to match LADBS plan check expectations and we respond to comments through approval.
Can you support LA hospital projects under HCAI (OSHPD)?+
Yes. A large portion of our work is HCAI/OSHPD OPM (preapproved equipment) and OSP (special seismic certification) for equipment going into Los Angeles County hospitals. We handle the full preapproval cycle — design, AC156 shake table test planning, peer review, and submittal — per HCAI PIN 55/62/68 and CBC §1705A.13.
What ASCE code edition do you design to in Los Angeles?+
The 2022 California Building Code (CBC) adopts ASCE 7-22 with California amendments. All our nonstructural anchorage and component design for LA projects follows ASCE 7-22 Chapter 13 (with Chapter 15 for non-building structures where applicable), including the updated H_f, R_μ, C_AR, and Ω₀ provisions.
Do you have a physical office in Los Angeles?+
Our office is in Arcadia, CA — within Los Angeles County — and we serve the entire LA metro and Greater Southern California region: Downtown LA, Long Beach, Pasadena, Santa Monica, the San Fernando and San Gabriel Valleys, the South Bay, and the Inland Empire.
How quickly can you turn around an anchorage calculation package?+
Standard equipment anchorage packages typically turn around in 5–10 business days. Rush turnarounds are available for urgent LA-area submittals — contact us with the equipment cut sheets, anchor substrate, and required Sds/Ip and we'll quote a schedule.
Ready to talk about your LA project?
Send us your equipment cut sheets, project location, and required SDS / Ip. You’ll get a scope, fee, and schedule from a California-licensed engineer — typically within one business day.
