Boundary Surveys establish property lines/corners, but can also be used to delineate boundaries for easements. Boundary surveys should be performed any time you buy property (Is it 76.8 acres, or 78.6?) or want to have your acreage assessed, whenever you want to create a new parcel, when you erect a fence or structure close to a property line, or are trying to resolve a dispute with your neighbor. 

Construction Surveys provide horizontal alignment (line) and vertical control (grade) to assure your project conforms with design specifications.

Topographic Surveys determine the "lay of the land" and can prove instrumental in optimizing the location of a proposed structure and/or facilitating the site design of a commercial or residential project.
