How to Choose a Structural Engineer?

Start with project-type fit. Structural engineering splits into specialties by building type and material — wood-frame residential, steel and concrete commercial, seismic retrofit, foundation work. Ask for two or three completed projects like yours, and ask what the structural challenges were. An engineer who can describe the hard parts of your project type from experience is worth more than one with an impressive but irrelevant portfolio. Then verify the license with the state board — two minutes online — and read the proposal like a scope document: which drawings, which calculations, which code edition, how many plan check rounds, what triggers additional fees. Experience, license, proposal. In that order.

In the interview, ask questions with no safe generic answer. What structural system would you expect for this building and why? What does the geotechnical report need to tell you before you start foundations? What's the lateral system, and how does it fit the architecture? You're not looking for a specific answer — you're looking for an engineer who reasons from your project rather than reciting credentials. Also ask about the team: who actually does the work, who stamps it, and how are they involved day to day? In many firms the person you meet isn't the person who designs. That's fine as long as it's disclosed and the responsible engineer is genuinely engaged — but you deserve to know the arrangement before you sign.

The proposal should read like it was written for your project, not assembled from a template. Project-specific assumptions, named deliverables, a realistic timeline with dependencies, and clear additional-services language. Compare proposals on scope first and price second — the cheapest structural proposal with undefined scope is the most expensive one you'll ever sign. Finally, trust the working relationship. You'll be answering this engineer's questions for months. Responsiveness in the proposal phase predicts responsiveness during design. If they're slow and vague while trying to win your business, imagine them after they've been paid.

• Project-type fit: ask for two or three completed projects like yours
• License: verify active status with the state board before anything else
• Proposal: named deliverables, assumptions, exclusions, and round counts
• Team: know who designs, who stamps, and how involved each one is
• Responsiveness now predicts responsiveness later — test it during selection
