The Post-Construction Evaluation and Management System has been operated over the past 20 years not only to analyze the performance of large-scale construction projects, and but also to provide useful reference data for future similar projects. Although the Post-Construction Evaluation and Management Center has been legally designated and operated since 2020, various problems have been occurring in the operation of the system. Accordingly, this study proposes strategies for facilitating Post-Construction Evaluation and Management System in terms of the following three aspects: (1) improving the implementation rate of post-construction evaluation; (2) improving the information management system related to post-construction evaluation; (3) improving the utilization of post-construction evaluation outcomes. Based on the results of this study, a specific action plan will be prepared, which is expected to contribute to the efficiency of construction project performance management in the future.

According to relevant laws, in the case of a construction project with a total construction cost of 30 billion won or more, a post-construction evaluation must be performed after completion. In addition, a post-construction evaluation report must be prepared and entered into the Continuous Acquisition & Life-cycle Support(CALS). As a result of reviewing the currently accumulated post-construction evaluation reports, since the report is not standardized, it is difficult for public project owners to write the report. It also hinders the post-construction evaluation and management center from verifying contents, analyzing data, and deriving meaningful results. In order to improve the convenience of the public owners who must conduct post-construction evaluations and the work efficiency of the center, evaluation factors were standardized and a standard post-construction evaluation report format for road construction was developed in Excel. Through this, the data in the reports will be effectively accumulated, managed, and analyzed, so that meaningful results will be produced and be helpful in future construction work.

Development of social overhead capital (SOC) requires huge national finance, and performance issues such as cost-efficiency, safety, and environment have been constantly raised. However, currently each construction client has limited access to its own projects' performance without analytic methodology for industry-level comparisons and benchmarking for improvement. To overcome this problem, this study proposes a comprehensive performance analysis framework for post-evaluation of large-scale construction projects. To this end, this study performed a case study of advanced countries (the U.S., the U.K. and Japan) and consultation with related experts to develop a tailored performance analysis framework for the Post- Construction Evaluation and Management system in Korea. The developed framework covers three categories (project performance, project efficiency, and ripple effect), nine areas (cost, schedule, change, safety, quality, demand, benefit-cost ratio, civil complaint, and defect), and 31 detailed metrics. Using industry-level project performance database and statistical techniques, the proposed framework can be used not only to diagnose excellent and unsatisfactory performance areas for completed construction projects, but also to provide reference data for future similar projects. This study can contribute to the improvement of clients' performance management practices and effectiveness of construction projects.

건설공사 사후평가 제도는 공공건설사업 수행결과를 반영하여 향후 유사한 공공건설사업의 계획 수립 시 활용되어져야 하나, 현행 제도는 당초 기획 계획 당시에 추정한 수요, B/C비율, 공사비, 공사기간 등 예측치와 건설공사 완공후 일정기간(3년 내지 5년) 경과후에 측정한 실제 결과치를 단순히 비교하여 제시하는 수준에 그치고 있다. 또한 대부분 공공발주기관에서는 수동적인 사후평가 업무수행에 그치고 있어 제대로 환류가 이루어지않고 있다. 이에 본 연구에서는 공공발주기관을 대상으로 설문조사를 실시하여 건설공사 사후평가 제도의 수행현황을 파악하였으며, 국내 사후평가 제도와 유사한 미국과 일본의 건설사업 평가체계를 벤치마킹하였다. 또한, 건설공사 사후평가 제도와 관련된 국토부 실무담당자와의 수차례 업무회의를 실시하여 사후평가 수행의 적시성 확보 및 활용성 강화방안을 제시하였다. 이와 같이 건설공사 사후평가 제도 개선을 통해 건설사업 수행과정에서의 목표 및 성과에 대한 확인 점검 분석 체계를 내실화하고, 건설공사 특성별로 평가내용 및 방법을 차등화함으로써 발주청의 사후평가 수행에 대한 실천력이 제고될 것으로 기대된다.

This research was thereby made to study and analysis ecological, landscape, and stability qualities of roadside cut Slopes in expressways and national highways that went through revegetation works. Also, evaluation items and framework for integrated assessment of plant structure and restored state for the maintenance were suggested. Following is the summary of the result. firstly, for stabilization of introduced native plant species on roadside cut slops, assessment on the post-project environmental management through long-term monitoring and maintenance works must be made. It signifies a form of authentic recovery and restoration by the native plants. second, current evaluation framework on the test beds is well managed with clear evaluation standards and table while its method of assessing the post management with only test bed results lacks conformity with this study site. Newly developed evaluation framework on the post construction sites is estimated to be used as assessment standards on any roadside construction sites. Third, after site investigation distinction was observed among different revegetating construction types in the long-term perspective. Due to the different duration time of vegetation state between seed-spray measures(degraded in time) and layer-spray measure(maintained), the use of coarse straw-mat mulching work or Coir net was suggested in long term maintenance of cut slopes. forth, segmentation of post environmental assessment is organized into three large categories of "ecological", "stabile", and "landscape" qualities regarding post restoration quality and stability of slope through native plants with which categories marks 50, 30, 20 points of rates. fifth, components of the post environmental assessment were segmented in twelve categories driving results from former experimental construction and newly focused items on site. In the future, it is possible to propose a customized assessment method considering the location and location of construction work if the research on the application of post-environment assessment methods for road construction surface recording is conducted systematically.

Despite the serious lack of parking lots, studies on parking lot expansion are insufficient; research on users' satisfaction following parking lot expansion is practically nonexistent. Therefore, this study sought to provide basic data for the parking lot expansion of old apartments by comparatively analyzing users' satisfaction before and after the parking lot expansion through a questionnaire survey that targeted residents benefiting from the expanded parking lot. Results revealed a low post-occupancy satisfaction with the parking lot expansion despite the parking lot expansion and improvement of the parking lot environment. This was because the parking lot was not expanded up to the second basement floor due to the lack of appropriate parking space. Other factors included the construction cost burden and lack of connectivity of the basement parking lot with elevators. The results actually raise the need for the establishment of an optimally suitable expansion plan and development of method and technology requiring lower cost and shorter construction period in the design and construction processes for parking lot expansion. Through post-occupancy evaluation (POE) after parking lot expansion, this study quantitatively identified the problems associated with the parking lots of old apartments and ensuing expansion effects. The findings in this study can be used as basic data to seek a suitable diagnosis and evaluation method for the parking lots of old apartments.

건설공사의 품질을 확보하고 예산의 절감을 도모하는 등 건설 프로젝트의 성공 여부를 판단하기 위해서는 객관적인 평가지표와 그에 대한 투명성 확보가 필요하다. 건설부문을 포함한 공공사업의 경우 대규모 예산투입이 이루어지고 있지만 그 결과물로 인한 편익을 산정하기 어려울 경우가 많아 공공사업의 효율성과 효용성이 떨어진다고 인식되고 있다. 따라서 본 연구에서는 500억 원 이상의 공공공사 중 사후평가를 실시하는 시설물에 대한 소비자 만족도를 정량화하는 것을 범위로 하여, 공공공사 사후평가 시 체계적이고 정량적인 측정이 가능할 수 있도록 주민 호응도와 사용자 만족도 항목을 중심으로 하는 사후평가 측정기준을 제안하고자 한다.
