Owner's engineer

When the design capability sits on the contractor's side of the table — as it does in EPC and design-build — the owner needs its own eyes. The owner's engineer reviews design deliverables against the contract and the owner's requirements, witnesses tests, monitors progress and quality, advises on claims and changes, and generally ensures that the owner's acceptance decisions are informed ones. On lender-financed projects a sibling role, the lender's engineer, does the same for the money.

The role's boundaries are its whole design. The OE reviews and recommends; the contractor designs and warrants; the owner decides. An OE that drifts into re-engineering — comments that redesign rather than review — slows the project, muddies the warranty, and hands the contractor a ready-made defence: the design failed where the owner's engineer changed it. The discipline of commenting on compliance rather than preference is what separates a review function from a second design office.

The opposite failure is the OE as ornament: retained for lender optics, under-scoped, reviewing at a depth that assures nothing. The title on the organogram is not the function; the review scope and its authority are.
