The procedural requirements for field fixes are generally no different than they would be if those same kinds of operations were to be made in the shop. For example, the welding operations should still be done in accordance with AISC and AWS requirements, including an approved welding procedure specification. Bolting should still be done in accordance with AISC and RCSC requirements.
While we're on the subject of field fixes, AISC has a seminar that addresses many of the most common ones, including recommendations for how to prevent the actual problems from occuring in the future.. I've pasted in the description below. For more information, go to this link:

Common Problems in Design, Fabrication and Erection - Solutions and Prevention
by James M. Fisher of Computerized Structural Design and Lawrence A. Kloiber of LeJeune Steel
The purpose of the seminar is to discuss design, fabrication, and construction problems that have occurred on structural steel projects. Solutions to recurring problems, and suggestions to prevent problems from occurring will be presented.
Topics include design issues such as material specifications, connection design requirements, use of standard details, sizing material for constructability, use of mill reports, perimeter details for tilt-up and pre-cast concrete walls, design procedures for fast track construction, electronic data transfer and shop drawing approval procedures.
