ABSTRACT

An engineering survey to determine the existing height of constructions is a frequent requirement that the land surveyors are faced with. A height survey may be needed to verify building elevation while in construction, or according to the legislation, in order to apply for a building permit a detailed topographic plan must be conducted. Such a topographic plan must be prepared by licensed surveyor and include the measurements of nearby properties, adjacent with the land parcel on which the building authorization is desired, with the respective corner point elevations and the building apex elevation, the corresponding uppermost point of the roof. The present article exemplifies traditional methods of height determination, in both situations if the measurement of the horizontal distance between the topographic instrument and the building is available or not, as well as a precision comparison with the new modern alternativ, the reflectorless total station.
