When would you use a construction survey?

A construction survey is specifically utilized to guide the design and layout of new constructions. This type of survey helps ensure that the building aligns with the planned design, is correctly positioned on the site, and adheres to local regulations and zoning laws. During this phase, surveyors assess the site conditions and can pinpoint the exact placement of foundations, utilities, and other essential components of the project.

The other options, while related to surveying practices, pertain to different purposes. Evaluating land for sales typically falls under land surveying, which focuses on determining property values and features rather than guiding construction. Documenting existing properties before construction is more aligned with pre-construction surveys, which record the state of the property prior to any work being done, rather than focusing on the layout for new construction. Checking property boundaries is a distinct task that involves boundary surveys, primarily concerned with delineating legal property lines rather than the specifics of construction layout.
