하수관거정비 임대형민자사업(BTL) 성과평가방법 개선에 관한 연구

Abstract

The government has been implementing Build-Transfer-Lease(BTL) projects in earnest since 2005 for the purpose of the sustainable growth for creating new jobs, active response to the increase of social welfare spending and the utilization of the creativity and efficiency in the private sector and the Ministry of Environment has also implemented BTL Sewer Rehabilitation Projects in earnest in conjunction with such national policies. In Jeju, 7 BTL projects are in progress in 2013 and 3 projects of them have been completed and are ready to operate. Thus the purpose of this study is to suggest policies to reduce the disputes on the evaluation results which might occur between the competent authorities and contractors and ensure the fairness and objectivity in the evaluation process for the effective operation of BTL projects by analyzing the performance evaluation methods in the early stage of operation. To this end, this study has surveyed and analyzed the performance evaluation data (2011.07 ~ 2013.03) regarding 3 projects in operation. As a result, 5 problems have been extracted and the solutions to those problems have been prepared as follows. First, the performance evaluation indexes are composed of 4 categories, 22 evaluation indexes and 149 evaluation items, and thus it is impossible to conduct objective and in-depth evaluation in a short period of time. Thus it is critical to reduce the evaluation items by deleting and integrating some evaluation items. Second, there is wide deviation of weights between items(up to 149 times) and some evaluation items with higher weights score high points constantly in the initial stage of operation, indicating there is a necessity of the modification of weighting methods in such a way that give a higher weights on 'planning' in the initial stage, on 'continued management and facility management' in the middle stage and 'on cleaning, inspection, repair and services for residents' in the late stage after classifying the project operation into 3 stages-early stage, middle stage and late stage. Third, some evaluation items with low weights have not been improved. To resolve this problem, it is essential that the evaluation commission request the improvements and decide the implementation period of improvements; otherwise impose penalties depending on the willingness/effort for improvement. Fourth, 88% of evaluation items do not objectively work as qualitative evaluation items. To solve this problem, it is essential to prepare the standards enabling the quantification of qualitative evaluation items. Fifth, there is the likelihood that some non-protectional evaluation commission members may evaluate subjectively. Thus this study has suggested the following solutions: expanding the evaluation commission (subdivisions of the evaluation commission according to expertise and the expansion of residents' participation in the evaluation commission), allowing the subdivisions of evaluation committee to evaluate the fields where they have expertise, and applying different weights to individual sector. Meanwhile this study has the limitations in that this study has been conducted, limited to 6 quarters only and thus it was difficult to forecast the future trend; and this study did not suggest more specific solutions to the problems identified through this study. Thus it is essential that futures studies derive more specific problems through an analysis of the evaluation points by individual evaluators and of the individual evaluation points of 149 items; and address the issues relating to the performance evaluation about influent which has been implemnted as the sewer systems have been operating more than 3 years for the purpose of operating BTL Sewer Rehabilitation Projects more effectively.
