What date must be shown on a drawing if a surveyor visits a site on multiple days?

The correct choice is to show the date of the last site visit on a drawing when a surveyor visits a site on multiple occasions. This practice is crucial for several reasons.

Firstly, the date of the last site visit reflects the most current and relevant information collected by the surveyor, which is essential for ensuring accuracy in the survey results. Conditions at a site, such as land use, physical features, and legal boundaries, can change over time, so the last date provides a clear reference point for when the data was gathered. It indicates to anyone reviewing the document that the information presented is the most up-to-date and reliable.

Additionally, assuming there are multiple visits and potential changes documented, using the last date aids in establishing a timeline for any modifications that may affect the surveyed land. This helps all parties involved in the transaction or land use to understand the context and validity of the survey, making the last site visit date the most beneficial choice for transparency and accuracy in land surveying documentation.
