To mitigate is to reduce the severity or consequences of a problem. In property recovery, the word describes an objective rather than a single procedure.
What this means at your property
Addressing an active water source and arranging appropriate extraction can limit additional damage. Replacing a stained ceiling is a later repair task. Both may belong to the project, but they serve different purposes.
What should an authorization to mitigate include?
Clarify the immediate tasks, affected areas, access needs and approval limits. Ask how new findings will be communicated and which repair decisions will follow separately, especially where another trade must correct the original source.
