What does an as-built survey verify after a project is constructed?

1. Compliance to blueprints

2. Soil stability

3. Environmental impact

4. Construction materials used

The correct answer is: Compliance to blueprints

An as-built survey primarily verifies the actual location and specifications of a constructed project in relation to its original design documents or blueprints. This type of survey is conducted after construction is complete to ensure that the project has been built according to the approved plans and specifications. It assesses whether the dimensions, positions, and elevations of the constructed features match those outlined in the drawings. While the other options may be relevant to various aspects of construction and project management, they do not pertain directly to the purpose of an as-built survey. For instance, soil stability pertains to geotechnical investigations that occur before or during construction to ensure a solid foundation. Environmental impact refers to the effects that a construction project has on its surroundings, often evaluated during the planning stages. Lastly, the verification of construction materials used involves quality control and assurance processes that ensure materials meet the required standards and specifications. Thus, while all these factors are important in the overall construction process, they do not directly relate to the primary function of an as-built survey.
