Serving Washington State
Seismic Engineer in Washington
ASCE 7-22 nonstructural anchorage, special seismic certification, and AC156 shake table testing — for Seattle, Tacoma, Bellevue, Spokane, and statewide hospitals, data centers, labs, and critical facilities. Stamped by licensed PE/SE engineers.
Licensed Seismic & Structural Engineers for Washington Projects
From our office in Arcadia, CA we support manufacturers, mechanical contractors, design-build teams, and facility owners across Washington on the seismic compliance work that's hardest to get right: nonstructural anchorage to ASCE 7-22, IBC special seismic certification, 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 Washington hospitals, labs, data centers, and critical facilities. Submittals formatted for Seattle SDCI and statewide plan check.
IBC §1705.13 / ASCE 7-22 §13.2.2 special seismic certification for equipment and components that must remain operational after a seismic event. Test plan oversight for ICC-ES AC156 shake-table programs.
Test plan development, AC156 RRS calculations, and witness/peer-review services at independent testing labs. Reports formatted for IBC special seismic certification submittals nationwide.
Walkthrough assessments and prioritized mitigation reports for existing Washington facilities — schools, healthcare, data centers, and government buildings — using the FEMA E-74 framework.
Built for Washington Code Authorities & Project Types
Washington projects sit at the intersection of the Washington State Building Code, local jurisdiction review, and (for healthcare) Washington State Department of Health requirements. Our deliverables are formatted to clear plan check the first time — with the assumptions, references, and stamps each authority expects.
Code authorities we work with
- • Seattle Department of Construction and Inspections (SDCI)
- • Washington State Building Code Council (WSBCC)
- • Washington State Department of Health (hospital & healthcare facilities)
- • Tacoma, Bellevue, Spokane, Everett, Olympia building departments
- • Local jurisdiction plan review for schools and public buildings
Typical Washington project types
- • Hospital MEP equipment anchorage & special seismic certification
- • Data center battery, UPS, switchgear, and CRAC anchorage
- • Biotech / pharma cleanroom equipment anchorage
- • High-rise office tenant improvement seismic restraints
- • Distribution system bracing (piping, ductwork, conduit, cable tray)
- • Existing-facility FEMA E-74 nonstructural risk assessments
Frequently Asked Questions — Washington Seismic Engineering
Do you handle Seattle SDCI submittals for seismic anchorage?+
Yes. We routinely produce PE/SE-stamped anchorage calculations and details that are submitted to the Seattle Department of Construction and Inspections (SDCI) under the Washington State Building Code, which adopts ASCE 7-22 by reference. Our packages are formatted to match plan-check expectations and we respond to comments through approval.
Can you support hospital projects in Washington?+
Yes. Washington hospital projects fall under the Washington State Department of Health and local plan review, using IBC §1705.13 and ASCE 7-22 Chapter 13 for nonstructural seismic certification. We provide the same PE/SE-stamped anchorage, bracing, and special seismic certification packages we deliver in California, adapted to Washington code adoption and local reviewer preferences.
What ASCE code edition do you design to in Washington?+
The Washington State Building Code adopts ASCE 7-22 with state amendments. All our nonstructural anchorage and component design for Washington 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 work outside Seattle?+
Yes. We serve the entire state of Washington, including Tacoma, Bellevue, Spokane, Everett, Olympia, Bellingham, Vancouver (WA), and the Tri-Cities. Our Arcadia, CA office coordinates remotely and travels to project sites and testing labs as needed.
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 Washington 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 Washington project?
Send us your equipment cut sheets, project location, and required SDS / Ip. You'll get a scope, fee, and schedule from a licensed engineer — typically within one business day.
