Strategic planning for the structures the world depends on.

Structura Management provides a full range of infrastructure asset management and engineering services, including: • Strategic asset management planning — data-driven lifecycle forecasting for bridges, marine structures, and civil infrastructure • Bridge and marine/port inspection and condition assessment — fixed and movable bridges, piers, wharves, docks, bulkheads and other waterfront infrastructure including underwater inspection • Capital program development and delivery — scoping, project controls, permitting, and construction management • AI analysis and predictive maintenance for bridges — machine learning models and algorithms that analyze condition data to forecast deterioration and optimize maintenance timing • Lifecycle cost analysis — quantitative modeling of repair vs. replacement scenarios to inform capital investment decisions • Algorithm development — custom analytical tools for infrastructure data processing and performance prediction • Expert testimony — forensic engineering analysis and expert witness services for bridge failures, capital asset disputes, and infrastructure litigation • Engineering coaching and mentorship — structured professional development for engineers navigating technical leadership and business development

Two projects stand out — one that made national headlines, and one that didn't. The West Seattle Bridge: In early 2020, Principal Engineer Matthew Donahue — then serving as Division Director for Roadway Structures — led the team that discovered rapidly accelerating shear cracks in the West Seattle Bridge, a critical transportation link serving tens of thousands of daily commuters. His team made the consequential decision to close the bridge immediately, before a potential catastrophic failure. To stabilize the structure while a long-term repair was designed, engineers threaded and tensioned nearly ten miles of high-strength steel strands along the interior of the bridge box girder, generating millions of pounds of lateral compression to arrest the cracking. During this time the team also designed and installed an emergency/long-term Structural Health Monitoring System and crepaired bridge commissioning with full scale live load testing. The bridge reopened in 2022 after a full repair. The counterfactual — a sudden failure of a busy urban bridge — is one most people prefer not to consider. An algorithm most people will never hear about: CEO Alison Yates spent months working on a machine learning model designed to extract meaningful signal from a complex, noisy dataset. After extensive iteration, a breakthrough using cosine similarity — a mathematical technique for measuring the directional alignment of data vectors — quietly and dramatically improved the model's performance. The technology that resulted touches thousands of people's daily experience. It will never have a press release.

Strategic asset management uses historical condition assessment data, risk assessment and target performance levels to forecast routine and major maintenance and capital replacement needs across a structure's full service life. Rather than responding reactively to failures, it helps owners prioritize spending across a portfolio of assets to maximize return on investment and minimize life-cycle costs in a resource constrained environment.

Proactive maintenance identifies and addresses deterioration before it escalates into major structural failures or interruptions in operations. Research consistently shows that preventive interventions cost 4–10 times less than deferred rehabilitation. A strategic maintenance plan also helps agencies spread capital spending more predictably across budget cycles, avoiding costly emergency expenditures and service disruptions.

We provide strategic asset management and inspection services for fixed and movable bridges, marine and port structures (piers, wharves, docks, bulkheads), underwater structural elements, scientific and energy generation infrastructure, and other critical civil assets. Our team has field experience across a broad range of structure types and environments, including arctic cold-regions and international settings.

Fixed bridge inspection follows FHWA and AASHTO standards to assess structural elements for load capacity, material deterioration, and code compliance. Movable bridge inspection adds evaluation of the mechanical, electrical, and hydraulic operating systems — including bascule, swing, and vertical lift mechanisms — requiring specialized expertise in both structural, electrical and mechanical systems.

Structura Management, PLLC has applications under review for Women-Owned Business Enterprise (WBE), Small Business Enterprise (SBE), and Disadvantaged Business Enterprise (DBE) certifications at both the WA State and Federal levels. Principal Engineer Matthew Donahue, PE is an ASCE COPRI Board Certified Port Engineer (2025) and was recognized as an NHI Bridge Inspection Instructor of Excellence in 2024 and 2025.

Yes. Our WBE, SBE, and DBE certifications qualify Structura for set-aside contracting opportunities with federal agencies, state departments of transportation, port authorities, and municipal transportation departments.

Yes, and we want more! Matt worked on Thirty Meter Telescope (TMT) in the past and brings 30+ years of experience managing large, complex movable structures — exactly the kind of engineering challenge posed by steerable radio dishes, rotating observatory domes, and precision tracking mounts. Alison holds advanced degrees in physics and optics and has spent years working with high performance lasers, precision optical systems and instrumentation. A telescope sits squarely at the intersection of our two backgrounds. If you're building or maintaining one, we'd genuinely love to talk.
