PROBLEM TO BE SOLVED: To reduce the carrying-in man-hours of finishing materials and to accelerate the work by bridging beams between columns erected on a floor slab, and arranging the finishing materials at the prescribed positions on an execution floor through the spaces between the beams with cranes from the outside of a building before installing a ceiling slab on the beams. SOLUTION: Beams 2 are hoisted and installed at the prescribed positions of columns 1 by first and second cranes 91, 92 movable in the ranges of loci A, B respectively. Markings are applied to the fitting positions of finishing materials on the floor slab of an execution floor, and the finishing materials are hoisted from the outside by the first and second cranes 91, 92 and are arranged on the floor slab of the execution floor through interval spaces S according to a layout plan. For arrangement, relatively large finishing materials are hoisted in dedicated racks and distributed by a conveying machine, and small finishing materials are lifted in the lump for each room to improve the execution efficiency of the finishing materials in the post-process. The finishing materials are hoisted by the first and second cranes 91, 92 without assembling a lift, and the man-hours and cost are reduced.
