What does engineer of record mean?

The licensed PE in responsible charge whose seal certifies the engineering design on the permitted documents for a discipline (commonly structural).

What is the difference between EOR and engineer of design?

The EOR holds legal/professional responsibility for sealed work; design staff may produce calculations and sheets under their supervision.

Is the EOR liable for construction defects?

Generally for engineering design in the sealed documents—not for contractor means/methods or deviations from those documents unless professional standard of care is implicated.

Does the EOR review shop drawings?

Yes for engineering scope—confirming fabricator details align with design intent via the shop drawing process.

Engineer of Record (EOR): Role, Responsibilities, and What the Stamp Actually Means

The engineer of record is the licensed professional who takes legal and professional responsibility for the engineering shown on sealed permit drawings. The stamp certifies responsible charge and code alignment of the engineering design—not perfect cross-discipline coordination by itself.

What the EOR is responsible for

Structural systems, load paths, code compliance for the engineering scope, and the documents of record the contractor must follow unless formally revised.

What the stamp does not certify

It does not certify full arch/MEP coordination, shop fabrication quality, or field-built conformance—those sit in other contracts and review paths.

Construction phase role

Shop drawings: confirm intent vs fabricator proposals (shop drawing review context).
RFIs / ASIs: structural questions route through the EOR; architect-led ASIs affecting structure need EOR coordination.
Observations vs inspections: periodic structural observation ≠ continuous special inspection trades.

Delegated engineering

Delegated packages still require explicit EOR acceptance—the EOR cannot silently offload incompatible assumptions. Coordinate via disciplined submittal review.

Why coordination errors still appear on sealed sets

Code-compliant structural sheets can still clash with ducts, shafts, or civil interfaces. That is a document-coordination class of risk—where AI drawing review cross-referencing disciplines complements the EOR’s engineering scope.

Frequently asked questions

Engineer of record meaning?

Licensed PE responsible for sealed engineering on the permit set.

EOR vs EOD?

EOR holds seal and responsibility; EOD may produce work under supervision.

Liable for field defects?

Generally tied to design in documents vs contractor execution issues.

Shop drawing review?

Yes—for conformance to design intent on engineering submittals.
