Shop drawings stamped “Accepted as Noted” allow fabrication only. The fabricator will make the noted changes to the drawings and resubmit for final acceptance before shipping. “ACCEPTED” Drawing are required for shipment to project. Bridge members and other structures are generally designed in lengths, depths, and widths that can be transported from the fabrication source to the project. Field splices, if required, must be indicated and detailed on the shop drawings.
