PROBLEM TO BE SOLVED: To provide a construction method for a cylindrical tank improving manpower and equipment working efficiency, reducing cost and processing loss, and imparting a sufficient strength to the side wall after temporary assembling or welding. SOLUTION: In a construction method of a cylindrical tank in which a plurality of rectangular side plates 13 having a specified curvature are welded in multi-layer to form the side wall of a cylindrical tank 10, The vertical joints of the rectangular side plates 13 are connected by the first layer welding 14, and after a plurality of side plates 13 are temporarily assembled up to the uppermost stage while connecting the horizontal joints of the side plates by at least one of temporary welding 17 or jigs, the vertical joint and the horizontal joint are continuously processed by final welding 15 from the lower part to the uppermost stage.
