For how long should a Land Surveyor preserve original field notes and calculations?

The preservation period for original field notes and calculations is generally a vital aspect of a land surveyor's professional responsibilities. In many jurisdictions, including Tennessee, it is often understood that these records should be maintained for a minimum of four years following the completion of the surveying project. This timeframe allows for sufficient time for any potential disputes, claims, or questions regarding the surveying work to be addressed during the legally relevant period.

Keeping field notes and calculations for at least four years ensures that surveyors have access to the necessary documentation to back up their work or to defend their findings if challenged. This practice not only enhances professional integrity but also aligns with industry standards and regulatory requirements for maintaining accurate and complete records. Adhering to this timeframe protects both the surveyor and clients by providing evidence that can demonstrate the validity of the survey.

While some professionals may opt to keep records for longer periods, particularly for significant projects, the four-year retention period is a widely recognized minimum standard.
