What Is an Engineer of Record?

The phrase refers to the public record created when a sealed document is submitted to an authority having jurisdiction. Sealing is a personal act by a named licensee, and the standard it attaches to is responsible charge — the engineer must have exercised direct professional control over the work, not merely reviewed it or managed the people who did it.

That is why an engineer cannot seal a design prepared by someone outside their supervision, and why "plan stamping" is a licensing offence rather than a contractual dispute. The liability runs to the individual. A firm can be sued, but the licence that can be suspended belongs to a person.

The architect of record holds the same relationship to the architectural design and is typically the prime consultant, holding the agreement with the owner and coordinating the engineering disciplines as subconsultants. The engineers of record are responsible for their own scopes within that structure.

Coordination between them is a responsibility neither can delegate away. When a structural change affects the architectural design, both records have to move together, and the RFI process during construction is largely the mechanism for keeping them aligned.

Some elements are deliberately designed by others. Steel connections, precast panels, curtain wall systems, fire sprinkler layouts, cold-formed framing and temporary shoring are commonly delegated to specialty engineers working for the fabricator or subcontractor, who seal their own calculations and drawings.

The EOR does not become responsible for that delegated work, but does remain responsible for defining the design criteria it must satisfy and for reviewing the submitted design for conformance with the overall design intent. Where those boundaries sit is one of the most consequential things a specification section says, and ambiguity in it is a recurring source of dispute after a failure.

Sealing the permit set is not the end of the engagement. During construction the EOR answers RFIs affecting their discipline, reviews submittals and delegated design packages for conformance with the design intent, observes the work at intervals defined in the agreement, and evaluates any proposed substitution or field change.

Each of those responses is a professional judgment attached to a licence, which is why RFI responses from an EOR are worded carefully and why an engineer who is asked to approve a field change verbally will almost always ask for it in writing. The document record is the defence.
