In Japan, it is an urgent issue to manage proper wage level and holidays as well as enhance the labor productivity. The purpose of this research is to grasp the system and the role of the orderer which relates regulating work hours and securing wage levels in the U.S.A. based on documents and field research. It should also consider the difference of current system in Japan, and acquiring knowledge for future development in Japan. We acknowledged that there is no limit for total hours spent at work in working hour regulations in the U.S.A., however there is a system to pay 50% on top of their regular rate of pay for all hours worked over 40 hours in a workweek. The Davis-Bacon Act has a big influence on managing wage levels of skilled construction workers, and the role of the orderer is well established in the system in order to follow the regulations of the Davis-Bacon Act.
