Roles & authorities
Structural engineer of record
Also called: SER, SEOR, structural engineer
The structural engineer of record is the licensed engineer who holds professional responsibility for the structural design — foundations, framing, connections, reinforcement and the load paths that hold the building up. Their drawings and specifications set the requirements the structural work is inspected against, and they are the party who reviews structural submittals, answers structural RFIs, and evaluates field conditions or deviations that touch the structure. Where a special inspection program is required, the structural engineer of record's documents typically define what gets inspected.
Why it matters
Structural work is the classic concealed, hard-to-fix work: rebar and connections disappear into concrete and behind fireproofing, and a deviation found after the fact can mean opening up finished work or an engineering evaluation to leave it as is. The structural engineer of record is the authority who decides whether a deviation is acceptable or has to be corrected.
Their criteria are also what turn a structural inspection into a pass/fail check instead of a judgment call — the specified rebar, the cover, the weld, the bolt tension — so the field has a defined target and the inspection has something concrete to measure against.
How it shows up on site
Structural details and specifications driving the pre-pour and steel inspections, structural deviations routed back for a documented disposition, and concealed conditions photographed before cover so the record supports the engineer's evaluation.
