What should I ask an engineering firm before hiring it?

Before hiring an engineering firm, ask who will lead the work, which professional will review or seal eligible documents, what information is needed to begin, how uncertain existing conditions will be handled, and which disciplines or consultants are outside the proposal. Ask how the firm records assumptions, coordinates with the architect and contractor, handles owner changes, responds to AHJ comments, and communicates decisions. Request a written description of deliverables and exclusions rather than relying on a sales summary. The answers should fit the building or site, occupancy, design stage, and jurisdiction. The firm can explain engineering judgment and professional responsibility, but the AHJ alone determines its review requirements and approval.

The correct application of engineering firm interview questions starts with the actual project, not a generic promise. Confirm the jurisdiction, adopted code, design scope, existing conditions, required deliverables, and professional responsibility before relying on a conclusion. A responsible engineer documents assumptions and identifies information that still needs verification.

Project type, occupancy, existing construction, site conditions, code edition, agency requirements, and changes made after the original design can change the work. A concise answer is useful for orientation, but the signed or sealed project record must reflect the current scope and the authority's process.

• Confirm the authority having jurisdiction and current checklist
• Use current drawings, calculations, field evidence, and equipment information
• Separate engineering decisions from owner, architect, contractor, utility, and agency decisions
• Record assumptions, limitations, and questions requiring direct AHJ confirmation
