As-Built Surveys

   The purpose of an asbuilt survey is to record variations from original Engineering plans to what is actually built. The as-built survey should begin as soon as it becomes feasible—meaning that the actual horizontal and vertical locations of features in the completed structure should be determined as soon as the features are erected. 

  At times, variations from the original plans are recorded on new tracings of the working drawings, on which as-built data is recorded in the place of the original design data when the two happen to differ. Sometimes, reproductions of the original drawings are used with variations recorded by crossing out the original design data and writing in the as-built data.
