Does square-foot pricing work for engineering?

Square-foot pricing can provide a preliminary planning lens, but it is not a reliable substitute for a defined engineering scope. Buildings with the same area may differ in occupancy, structural systems, site constraints, equipment, energy requirements, existing-condition uncertainty, coordination, and permit deliverables. A responsible proposal ties the fee to professional tasks, assumptions, and documents rather than implying that area alone determines the work. The engineer must verify the project basis, and the AHJ—not a square-foot formula—sets the required submission.

The correct application of square-foot engineering 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
