According to the post evaluation scheme in Korea of a public construction project which is more than 30 Billion KRW, project performance is evaluated by investigating outcomes and effects of the construction after the completion of the project. The current post evaluation results can be used for planning and estimating a construction project in the future. However, it is not easy to utilized for an on-going project because the system does not provide the phase-based performance of a project. Although project planning performance is important for project initiation, few attempt has been made to evaluate planning performance in Korea. The purpose of this study is to provide a conceptual performance evaluation of planning performance using preliminary feasibility study conducted by Korea Development Institute. This study developed a planning performance database using data extracted from preliminary feasibility study reports of the completed 354 road construction projects. This study analyzed the performance of the planning stage of road projects by developing absolute metrics such as standard construction cost and standard construction schedule based on a Lane-Km. Using the standard construction cost and schedule metrics, the planning performance was analyzed by project characteristics. The results of this study can be used for phase-based performance evaluation from planning phase to construction phase.

오늘날의 건설사업 환경은 차별화 ${\cdot}$ 정보화 ${\cdot}$ 특성화 ${\cdot}$ R&D등 지식과 기술 및 창의성을 바탕으로 한 창조적 결과물 생산으로의 요구를 확대하고 있다. 이러한 환경은 건설 사업을 수행하는 기술자 집단에게 사업수행의 미래 가치적 최적화를 위해 기획과 계획에서부터 시공과 유지관리 및 장기 지속가능성까지 보장하는 생애주기차원의 사업수행을 요구하는 것이기 때문에 사업의 타당성 분석에서부터 실시간 정보처리와 가치창조를 위한 사업수행 계획이 절대적이라 할 수 있다. 본 연구에서는 그동안 국내 사업일정계획에서 적용하고 있거나 적용할 필요성이 있는 사업단계와 단계별 업무영역을 구분하고, 정보화 운영관리 방안을 분석함으로서 국내 건설 환경에 적합하고 신뢰성을 보장 할 수 있는 일정계획을 수립할 수 있는 방향을 제시하고자 한다.

The construction of Pusan National University Yangsan Hospital is a new construction of a medical town in Yangsan. It is a case that CMr participated in the project from planning to post-completion. It shows an actual proof of Construction Management business applied CM by each phase. In this case, CMr selected the design-build contractor in the planning phase and technically performed CM businesses in every single phase such as design and construction schedule management regarding application of Fast Track technique, procurement management and contract administration in phases based on the Fast-tract; technique, design review, VE in the design phase, change order management in the construction phase and operating and maintenance in the post-construction phase. This study would go far toward applying CM to Mega Turnkey projects by analyzing the problems of CMr's practical application to the project and providing guidelines for effective and efficient CM business implementation especially in the Turnkey projects.

Public institutions recognize the importance of cost management from the planning stage but they do not have an organized construction cost estimation and management system. Thus, at the stage of planning a new public construction project and estimating the cost, those in charge of budgeting estimate construction cost based on existing data and experiences, compare construction cost estimated after the basic design stage and the execution design stage with budgets, and then decide whether to continue the project or change the design according to the budgets. Therefore, we would develop the cost prediction model through regression analysis that can predict construction cost in Schematic Design Phase of the Public Multi-Family housing. Accordingly, if public institutions have a construction cost prediction model and management system that can estimate the optimum construction cost, they can make and execute budgets in a more efficient way than they do at present.

u-City projects are different with the existing urban development projects progress via convergence with IT technology. Therefore, it inheres many risk factors more than the existing development projects as including more complexity and variety. The risk management system to systematically manage those risks which get identified and quantified is required. Especially, the planning phase that is appeared the various forms has a large effect on the success of the business. However, the management of risk factors remains in the passive form. So the problems on u-City project in the planning phase and risk factors of existing development business were analyzed for the continuous growth and the successful performance of u-City project, and those risk factors was identified and quantified by using statistical technique. In the results of it, the core risk factors were obtained through which way and the basis for the effective risk management in u-City business is provided.

In the planning phase of domestic urban environment maintenance and improvement projects, a particular problem is the increase in service expenses and project cost with the establishment of plans under circumstances that exclude the residents or have incomplete consent from them and the public organization. This delays the promotion of the project. This study aims to resolve such problems by proposing a measure to introduce a privatepublic consultative body for residents and the relevant departments of the public sector, to encourage them to participate and establish plans together from the beginning. This is expected to contribute to the smooth promotion of the project, as it would remove the conflicting factors that are expected to be generated in the project implementation phase before they could emerge.

서울특별시는 지난 5월 16일 "서울특별시 지역건설산업 활성화에 관한 조례"를 개정 공포했다. 서울특별시는 사업의 기본계획 단계에서 분할발주 여부를 검토 시행하고, 활성화 추진 목표 달성 현황을 매 반기별로 건설위원회에 보고토록 제도화함으로써 지역중소건설업체의 분할발주 활성화에 물꼬를 텄다. 주요 개정내용으로는 지역 중소건설업자의 공사참여 기회를 보장하기 위하여 분할 발주 가능 여부를 판단함에 있어 예산편성과 기본설계 등 사업의 계획단계부터 검토 시행토록(제6조제2항, 신설) 했으며, 매년 반기별로 활성화계획의 추진 목표 달성 현황을 보고하되 정성적인 부분과 정량적인 부분을 모두 보고토록(제4조제6항, 신설) 한 것이다. 이번 조례 개정으로 서울특별시는 "공사의 성격상 공종을 분리하여도 하자책임 구분이 용이하고 품질 및 안전관리에 지장이 없는 기계설비공사 등에 대해 분리발주를 적극 적용함으로써 지역 중소전문건설업체의 권익을 도모하는 한편 타 시 도의 표본이 될 수 있을 것으로 기대한다"고 밝혔다.

Recently, the importance of Pre-construction is gradually increasing in construction business. In addition to increasing greatness, Pre-construction affect to success or failure of projects. However, current domestic construction business doesn't constitute exact concepts and systems, and there are a lot of problems such as disorganize management of construction because most of Pre-construction depends on supervisors' experiences. Therefore, according as doing this study, We are going to analyze the tendency of Pre-construction step and bring up designed operation systems between departments in construction company. So we can expect to develop efficiency by excluding unnecessary operation and formulating more improved operation process.

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.
