In order to verify the effectiveness of new methods of work aiming at the productivity improvement in one-unit-at-a-time refurbishment of apartment house, I investigated and analyzed man-hour data of a new method of interior wooden frame work named "Gi system" in consideration of practice effect and comparative evaluation with the conventional method of work. At first, productivity of "Gi system" was inferior to the conventional method of work. But after practice effect, it decreased by 30%-50% and surpassed that by 15%-50%. It means there is room for productivity improvement even in discontinuous and scattered interior refurbishment work by using suitable new method of work.
