When does a professional engineer need to visit a site?

A PE may need a site visit for structural distress, uncertain or concealed conditions, complex modifications, forensic work, high-consequence decisions, or inadequate photographs and measurements. A remote workflow can be appropriate when reliable records and field evidence answer the engineering question; the responsible engineer decides.

The correct application of professional engineering 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
