Does an engineering site visit change the fee?

A site visit can affect an engineering fee when the proposal did not include travel, field observation, measurements, testing, access coordination, or a written site report. The need depends on the engineering question, reliability of existing records, concealed conditions, project risk, and the responsible engineer's ability to accept professional responsibility remotely. A visit is not a substitute for design analysis, and remote work is not automatically inadequate. The engineer should define the visit's purpose and deliverable; the AHJ decides whether an inspection, observation, or other evidence is required.

The correct application of site-visit pricing 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
