What type of measurements does an as-built survey provide?

1. Preliminary estimates

2. Comparative data

3. Precise compliance verification

4. Static measurements

The correct answer is: Precise compliance verification

An as-built survey provides precise compliance verification, as it focuses on accurately documenting the final locations and configurations of structures or systems as they were constructed. This type of survey checks whether the finished work aligns with the approved plans and specifications. By employing accurate measurement techniques, such as GPS and total stations, an as-built survey ensures that all elements are positioned as intended, taking into account any deviations that may have occurred during construction. This detailed documentation is crucial for compliance with regulatory standards, project requirements, and for future reference or maintenance purposes. In contrast, preliminary estimates are more about forecasting and planning rather than verifying completed work. Comparative data usually refers to analyzing changes or differences over time or between projects, rather than confirming adherence to a specified design. Static measurements can indicate fixed points in space but do not inherently carry the compliance verification aspect that as-built surveys provide, which is critical for ensuring that construction projects meet all necessary specifications and regulatory requirements.
