폐기물과 오염물질 투기로 인해 발생된 오염지의 복원은 1980년대 초반 미국이 본격적으로 시도하여 현장조사, 위해도 평가, 타당성 검토의 3단계를 거쳐 복원대책을 수립하는 정형이 이루어졌다. 이 정형에서는 먼저 현장조사로 오염상태에 대한 자료를 수집하고 위해도 평가로 오염도가 인체와 환경에 미치는 위해도를 정량화하며 타당성 검토에서 위해도를 제거하기 위한 각종대안을 검토하여 최종안을 선정한다. 이 과정 자체는 합리적이었으나 여러 가지 시행착오를 거치며 과잉대책이 남발되고 사업효과도 미흡하여 점차 예산낭비의 대표적인 사례로 비판이 제기되었다. 시행착오의 가장 큰 기술적 원인은 위해도 평가와 별개로 타당성 검토를 수행하며 비현실적인 완벽복원을 추구한 탓이며 이를 극복하려는 최적화 기법이 90년대 초반에 소개되었다. 이 최적화기법은 타당성 검토단계에서 각 대안의 잔류 위해도를 산정하고 해당대안의 비용과 비교하여 위해도를 허용수준으로 줄이는 최소비용 대안을 발견하는 방법이다. 이 최적화기법을 실제 프로젝트에 적용한 결과 복원대책 수행에 기대 이상의 비용절감을 이루고 정부의 수용도도 높았다. 특히 정비대책에 현장조건의 특성을 활용하는 창의적 대안을 도입하면 효과를 극대화 할 수 있는 바 두 가지 사례를 소개하였다. 앞으로 상당한 투자가 예상되는 폐광오염 문제에도 이 기법을 적용하면 비용과 효과를 최적화할 수 있을 것으로 기대되어 그 모델을 제시하였다.

Total Project Cost Management System(TPCMS) was introduced with the purpose of increasing the efficiency of cost control for public construction project in 1994. In this paper, general perception of participants of the public construction project on the TPCMS was examined, and the problems in implementing the TPCMS was figured out through expert interviews and survey. Then better ways to implement the system were drawn based on the problems. To effectively manage the cost of public construction project, basically project cost should be estimated accurately in planning stage and managed based on it to have a project complete within the budget. In addition, the cost need to be managed in more systematic ways in terms of data collection and analysis, and the autonomy in managing the project cost given to the project owner needs to be expanded. Most of all, proper budget should be provided to prevent a project from delay through setting the priority of projects and proper budget allocation based on the priority.

Environment-indifferent developments have brought about a great deal of environmental pollution and a destruction of the ecosystem. The global interest in environmental pollution has emerged in accordance with the environmental regulations becoming ever stricter in the international society. Various attempts are being pitched in Korea such as the PERS (Prior Environmental Review System) and EIA (Environmental Impact Assessment) and they practice a significant impact on the construction industry. Recently, there have been cases where large-scale national development businesses are delayed and terminated or re-examined for their feasibility for not having reflected and analyzed the environmental factors of the natural and ecological environment. We must sustain the ecological functions and balance and minimize environmental pollution issues that can be caused by land developments and preserve the natural environment so to induce environmentally-friendly development businesses. Thus, this research paper proposes environmental review categories of the natural ecosystem sector that can be applied to all stages of construction businesses including master planning stages, basic planning and execution designing stage, construction stage, and maintenance stage. The environmental review categories proposed in this paper are expected to offer a great deal of support in terms of inducing environment-sustainable development to decision makers in the master plan stage, designers in the basic planning and execution designing stage, and construction managers in the construction and maintenance stages.

Road safety audit is the preventive enhancement strategy for safety. : it gets rid of beforehand the potential factor of a traffic accident in the stage of road planning and design and it evaluates the appropriation for road geometric structure or safety facility to prevent traffic accident in the stage of operation after the construction. Since this strategy is introduced to our country in the early 2000s, various projects have been processed and it was legislated recently. And now, the evaluation of past project for its continuation is needed. Therefore, in this study the evaluation of road safety audit on existing freeway is performed. The spatial extent of this study is Yong-dong line on which the safety treatment was executed in 2005 and 2006. And, the temporal range of this study is each 2-year of before and after from 2005 and 2006. The empirical bayes method of observational evaluation studies is applied to analyze. As a result, there is an effect of improvement on most of treated sections. But there is ineffective or negligible on some sections. Compared with the detail of treatment on each section, the effect of multiple or various treatments is good for that section. On the other hand, the section on which effect doesn't appear is the result of single or unimportant treatments. Throughout these results, the concrete analysis can be performed and the countermeasures designed for the section on which effect doesn't appear. Also it is used as reference to the future plan and direction of road safety audit on existing freeway.

Public construction projects are implemented by government or public agencies using public resources to enhance the welfare of the people. Therefore, this paper investigates the impact factors for public construction performance. Then, the weights for impact factors are assigned using AHP. The impact factors are categorized into construction policies, project management efforts, and project environment. Further, 16 detail impact factors are listed in each category. The results show that weights are ordered in appropriate budget, reasonable project implementation process, and pre-project planning. These impact factors are related with pre-construction management activities. However, construction related impact like procurement, work difficulty, and construction environment show relatively low weights. The results can be useful to improve construction performance with managing impact factors showed high weights.

Since 2004, the Korean government has been engaged in u-IT new technology verification projects in an effort to level up the industries. Recently, cases are reported that RFID/USN technology has been adopted and applied to business processes, mainly by large enterprises. However, further policies and support for the industries have been restrained because of unavailability of essential data for policy making. Therefore, the study examined the level of satisfaction among the actual recipient organizations from the 27 pilot projects to draw implications from the study result. Accordingly, the level of satisfaction was assessed in four project phases from RFID/USN building, utilization (technical quality), utilization (business quality), to maintenance. The study result showed that the technical stability reached a significant level but the level of satisfaction in the maintenance phase for the utilization and proliferation of the technology remained at the lowest. It suggested that a more specified policy support is needed in the maintenance phase to include inexpensive supply of tags and devices, a maintenance establishment of consortium to maintain reliability and continuity of service, strengthening internal competence of the beneficiary organizations for utilization of RFID/USN.
