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 that is used 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 estimations for projects of public works. It also contributes to improved staff morale and professional development. The new check system has five novel items compared with conventional verification methods of cost estimation. The proposed system was put into actual use in Japan, during which time necessary improvements were made. As a result, no mistakes in cost estimation were noted for about three years at the Port and Harbor Bureau of a city in Japan, where the first author of this article worked. The system was further refined and could be adapted for use by all local governments, including those with few staff members.
