A method and apparatus for performing field assembling (high precision alignment) work efficiently by eliminating any work miss in structural component assembling work where 180° turning state is expected and grasping the connecting/assembling posture (inclination) conditions of many components systematically in order to assist automation of assembling work of a structure and automatic crane control. A data sampling/recording (data logging) device for maintaining the assembled structure is also provided. The data includes vibration data on a multistory building at the time of an earthquake, deflection data on a vessel structure due to high waves, and the like. A state that the components of a structure are arranged to share common horizontal/vertical directions is the completed state of the structure. The reference lines of two components may not be aligned before the two components are interconnected, and they are only required to be moved in the direction in which the vector difference between the reference lines decreases. Since the posture changes through the movement, an electronic tag with a posture sensor for measuring the posture data in real time is attached to each structural component, and the moving means is feedback controlled in real time.
