Which action is appropriate if a mistake is found in a Density Report?

Making a strikethrough and initialing the correction is the appropriate action when a mistake is found in a Density Report. This approach maintains transparency and accountability in documentation. By striking through the error and providing initials, it indicates that a correction has been made while preserving the original information, which is crucial for maintaining the integrity of the report. This practice also allows for a clear audit trail, as anyone reviewing the document can see what was changed and who approved the correction, thereby minimizing confusion or misinterpretation of the data.

Utilizing correction fluid, ignoring the error, or simply contacting a supervisor without taking any immediate corrective action would not provide the same level of accountability or transparency, which are essential in managing construction documentation and ensuring accuracy in reported data.
