Texas Surveyors Practice Exam

What happens if a surveyor cannot find original surveys or records?

1. They must abandon the project

2. They may use approximate measurements

3. They can create new measurements without referencing the old

4. They have to conduct a detailed history search

The correct answer is: They may use approximate measurements

When a surveyor cannot find original surveys or records, using approximate measurements is a viable course of action. This approach allows the surveyor to proceed with the work by applying known data, established boundaries, and surrounding reference points to produce a functional survey. Approximate measurements can help to establish a reasonable estimate of boundaries or elevations, particularly when precise historical data is not available. Successful surveying often relies on the established context and interpolation of available data. Therefore, while it is ideal to reference original surveys, using approximate measurements can still lead to a valid and usable outcome when necessary. In practice, surveyors may utilize techniques such as the analysis of nearby known controls or secondary reference points to aid in forming these approximations. The other options are not suitable responses to the situation. Abandoning the project dismisses the potential for resolution through alternative methods. Creating new measurements without referencing old data would undermine the integrity of the survey since connections to existing records are fundamental in maintaining consistency and legal validity. Conducting a detailed history search can be a useful step, but it may not yield results in time-sensitive scenarios, and does not necessarily address the immediate need for the survey to continue.
