How Do You Hire the Right Structural Engineer for Your Project?

You hire the right structural engineer by verifying their PE license in your state, confirming they've done your specific project type before, and getting a written scope that spells out exactly what's included — calculations, drawings, plan-check responses, and site visits. The hiring decision has three legs: credentials, relevance, and clarity. Credentials means an active license in the project state and professional liability insurance. Relevance means they've engineered buildings like yours — a residential retrofit specialist and a high-rise designer are not interchangeable. Clarity means the proposal defines deliverables, exclusions, revision allowances, and how extras are priced before anyone signs.

The most expensive mistake is hiring on fee alone. A low proposal often hides exclusions: no plan-check responses, no site visits, limited revisions. When the building department issues corrections — and it will — every one of those exclusions becomes a change order. I've seen owners pay more in extras than the original fee. The second mistake is hiring the wrong specialist. Structural engineering is broad: seismic retrofits, commercial ground-up, residential additions, and forensic investigations are different practices. Ask for three comparable completed projects and actually call the references. An engineer who's never done your building type is learning on your dime.

When owners ask me how to vet an engineer, I give them the same checklist I'd use myself. It takes an afternoon and it prevents the failure modes I see most. Run through these before you sign anything.

• Verify the PE license on the state board website — active, in the project state, no disciplinary history
• Ask for three completed projects of the same type and call at least two references
• Get the scope in writing: calculations, drawings, plan-check responses, site visits, revision limits
• Confirm who does the work: the principal you met or a junior you'll never talk to
• Check professional liability insurance and ask how claims and errors are handled
• Compare proposals on scope completeness first, fee second — normalize what's included before comparing price
