The tasks which were determined by this research to be the most in need of and/or receptive to automation are listed and defined in Source Document 56. Beneath each listing of the individually top ranking tasks are task groups which are termed Cycles. These cycles are related by sequence and therefore considered to be candidates for the most efficient automation technology. In general, the types of tasks that are most common to all three areas are lifting, aligning, and connecting. Whether engaged in fabrication or erection activities, above grade or at grade, these three types of tasks represent a majority of worker time. (SD-56, p. ii)
