Steps
Identify any anchor rod that is bent, out of position, undersized, or otherwise nonconforming before column erection begins.
Obtain written approval from the project structural engineer of record before any repair, replacement, or field modification of anchor rods, per 1926.755(b).
Confirm the controlling contractor gives the steel erector written notice of any repair/replacement/modification of a column's anchor rods before that column is erected, per 1926.755(b).
Route the approval and notification paperwork through the erector's QC file for that column location.
Re-verify anchor rod condition against the engineer's approved repair detail before setting the column.
Known gotchas
Field 'fixes' such as torching an oversized hole or bending a rod into alignment without engineer sign-off are common Subpart R violations — never let crews freelance a repair.
The written-notice duty runs from the controlling contractor to the erector; erectors should confirm they actually received it in writing before erecting the affected column, not just assume it was handled.
