A New Check System of Cost Estimation of Project Designs in Japan’s Local Governments

Abstract

In Japan, “Pointing and Calling” is a known safety management method to prevent mistakes and ensure safety. This study constructed a new check system, “Verification Meeting/ Simple Verification Meeting,” that is based on the Pointing and Calling system and aims to prevent incorrect cost estimates for public works projects. It also contributes to improved staff morale and professional development. The new check system has five novel items compared with conventional cost estimation verification methods. The proposed system was put into actual use in Japan, during which time necessary improvements were made. As a result, there were no mistakes in cost estimation for about three years at the Port and Harbor Bureau of a certain city in Japan where the first author of this study worked. The system was further refined and could be adapted for use by all local governments, including those with few staff members.
