Comparative Analysis of SCE and Contract Cost for Disaster Impact Assessment System: Focus on Classification of Project Area and Relevant Government

Abstract

This study compares and analyzes the contract amount and Standard for Calculating Expenses (SCE) concerning the Disaster Impact Assessment System (DIAS) and provides the results as basic data for improving the system. The current status of low-cost contracts based on a contract price ratio of 70% or less compared to the standard cost was analyzed. A total of 640 cases with reliable data were examined. The result indicated that the ratio of low-cost contracts was more than 70% of the total: the ratio of low-cost contracts of DIR was 76.2%, DIA 100%, and SDIA 86.7%. In particular, DIA with a large project area tends to be contracted at a price lower than that of DIR or SDIA. Further, this study found that the ratio of low-cost contracts of local government was higher than that of the central government, and private ordering projects were contracted at a cost lower than that of public ordering projects. Moreover, it verified the current contract status of DIAS agency through quantitative figures, which heretofore has not been revealed. The analysis results were used as basic data for the development of causal loop diagram.
