Rooted in the Pacific Northwest

Serving clients since 1998, Brackenridge Structural Works was founded on a simple premise: structural engineering doesn't have to be intimidating. We partner with property owners, architects, and city planners to ensure our urban environments are safe, compliant, and ready for whatever nature brings.

Our team thrives on transparency, clear communication, and rigorous scientific modeling. Whether you're upgrading a historic unreinforced masonry building or assessing a newer mid-rise, we guide you through every step without the jargon.

Specialized Seismic Solutions

We don't just guess; we simulate. Our core competency lies in non-linear dynamic time-history analysis using ETABS, allowing us to predict exactly how your mid-rise structure will respond to site-specific seismic ground motions.

// OUR 3-STEP WORKFLOW

  1. 01. Initial Vulnerability Assessment: On-site structural mapping and historic document review.
  2. 02. Computational Modeling: Advanced ETABS simulations to identify failure mechanisms.
  3. 03. Retrofit Design & Execution: Delivering actionable, permit-ready construction documents.
