Repair detail shall then be done as required. • Welds shall be checked for fatigue cracks and repaired as necessary. • All structural steel is to be cleaned and painted after all repairs have been made. • Major spalls and delaminations of the substructure shall be patched and major cracks shall be injected with epoxy.
