Abstract
In 2001, a progress payment system for public works was adopted for two projects as a trial basis in Japan and its effectiveness compared with the traditional system were examined and verified. Furthermore, in 2002, a standard implementation program for the new payment system was produced by the Ministry of Land, Infrastructure and Transportation, and therefore many trial projects for the new payment system were commenced all over Japan.
In this report, we present the results of the consideration of the effectiveness, practical problems and improvement plans of adopting new payment system, based on the follow-up questionnaire survey for trial projects.
