“Land surveying is essential for all disciplines of engineering and architecture. We take the purpose of this discipline seriously as it measures and maps the surrounding environment using mathematics, specialized technology and equipment. Locating, describing, monumenting and mapping the boundaries and corners of a parcel with precision is what quantifies the value.”
