It's became essential that Korea construction companies should enter into the overseas construction market for their growth and sustainability. In order to comply with the client's required global standard and to compete with in the international market, the shifting the construction project management system to global level is required. In accordance with the demand, this paper proposes the top-level document of construction project management system as a to-be model that utilized in overseas construction projects. The project management plan ("PMP") suggested in this paper is not only the most appropriate one, which complies with the global standard, to be used when companies bid for international construction projects against foreign competitors but also has the process modeling and hierarchical structure.

Recently, the Construction Management service of domestic construction environment has being extended because that is an effective means to supplement owner's management and improve a total management of construction. But existing CM service guide is staying simply defined level about a work scope and procedure. So the standard CM guide needs to set a detailed plan of the project. Therefore, the key works were deducted by doing survey after the main work of CM service based on CM case studies and an existing CM service guide. That is expected to use CM contract and do service.

남북 쌍방의 정치 협상이나 현황에 의미를 두지 말고 제 3 세계 주관사를 초청하여 서울 신의주 간 고속도로 민자 사업을 계획, 시공 및 관리하자는 주장은 이상에 불과할 수 있다. 남북 간 정경 분리 원칙을 내세우지만 간단한 미풍에도 흔들리고 있는 것이 개성공단의 현실이다. 필자는 거창한 통일 관련 학자는 아니지만 도로를 사랑하는 사람으로 도로인에 남북 화합의 지휘자가 되라고 권한다. 통상 사업 초기, 기획의 미비로 드는 추가 비용을 예방비용, 평가비용, 실패비용으로 구성할 수 있는데 대기업들은 예방비용에 미리 투자함으로써 품질은 높이고 비용은 줄이는 전략을 구사하고 있다. 대북 인프라 사업은 예방비용에 투자하는 것과 같다. 북한에 투자하는 SOC 사업은 비용은 파악하기 쉬운 반면, 그것이 가지고 올 이익은 장기적이고, 위험도가 크며, 또한 편익을 정량화하는 것이 어려운 특성이 있어 반대 여론이 높은 것이 사실이다. 그러나 조건 없는 남북 경협을 주장하는 것이 아닌 이상 남북 양 정부 이익을 창출할 수 있는 제 3자 방식의 민자를 통한 도로 사업은 현재 논의되고 있는 어떠한 SOC 사업보다 타당성이 있다. 도로 건설 불가론이란 거대 여론앞에 풍전등화의 두려움에 떨고 있는 건설인들에게 북한 도로 시장이라는 커다란 선물 보따리를 정부가 앞장 서 풀어주길 기대한다.

As the national competitive power indicator, the infrastructures have been constructed with government's SOC budgets. However, even SOC budget is decreased, Public-Private Partnership Project (PPP project) has been introduced to solve demands on extending infrastructures, and among PPP projects, road projects take high portions. This study analyzes the operation & management item of financial model which is connected to the O&M cost and project proposal of previously proposed road project and analyzes the Korea Expressway Co.,'s project cost items and O&M tasks to reflect the characteristics of road projects. Based on results, this study suggests necessity of the O&M cost breakdown structure and the cost calculation standard on each cost item. Also, for the existing task execution tools, O&M cost calculation tool and finance analysis task tool will be integrated, and the system is suggested web-based system. Thus, it is expected that it contributes to the securing overall business values on PPP project and expending profit-base infrastructures.

The government introduced private infrastructure projects in order to reduce its financial burden by introducing private sectors efficiency and creativity and by utilizing their funds. Through revision, the act on the private investment of the infrastructure, many changes were made in the private investment system. The evaluation task to assess the project proposer's capability and to select a promoter is regarded as the most important process for fairness and transparency of the project. In this study, the improvement of project plan evaluation task of current private infrastructure projects is proposed based on the standard guideline for evaluation procedure of private infrastructure projects provided by Korea Development Institute. In addition, software program for evaluation procedure is made to improve the efficiency and enableconvenient evaluation task.

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.

각종 오염물질이 수계로 유입되어 침강하면 하상에 퇴적되는데 이 오염된 퇴적물 중 질퍽한 콜로이드상의 물질을 오니토라 일컫는다. 이 오염물은 저장소 및 물환경의 변화에 따라 수질 악화의 직접적인 원인이 될 수 있는 인, 질소 등의 영양염류를 수중으로 재용출시킬 수 있는 비점오염원 종류 중 하나이다. 하천 준설은 하천에서 저수용량 확보와 하상 유지관리 및 골재확보, 수질 개선을 위해 토사를 제거하고 그 토사를 운반선에 의하여 운반하여 지정된 투기장에 투기하는 일련의 공사를 말하며, 이를 통하여 비점오염원인 오니토를 직접적으로 제거할 수 있다. 준설의 필요성 판단 및 수질개선 효과를 모니터하기 위해서는 하천의 수질과 유량을 조사해야 한다. 이때 대상구간이 요구하는 수질 기준에 부합하지 않으면 오염퇴적물 준설 기준을 통해 준설이 필요한 구간 및 사업량을 결정한다. 준설 사업량의 경제적 타당성을 정량적으로 검증하기 위해 대상 구간을 준설을 하지 않을 시 오니토가 상시 용출된다는 가정하에 물재생시설로 이 오염물을 정화했을 때의 비용을 준설 사업비와 비교하였다. 본 연구에서는 하천공사 표준시방서(2007)에 제시된 오염퇴적물 준설 기준을 만족하는 서낙동강수계의 준설 계획 지구에 대한 계획 사업비와 해당 지구 하류에 위치한 물재생시설의 정화능력 및 운영비를 비교해 하천 준설 사업비에 대한 편익을 산정하였다.

Plant construction is being a motive power of national economic growth, because it is a higher value-added business which has enormous influence through other industry. But, plant projects management of the domestic company was poor. So, the development of EPC Business Process Management method has been encouraged. Therefore, this paper performed several researches for setting up the EPC Business Process Management Model for improving plant project management. And the details are as follows. First of all, this study collected the work procedure manuals of 12 large-sized international construction companies. Secondly, from the analyzing gathered EPC work procedure manuals, issues of work procedure manuals were analyzed and improvement plans were drawn out. Basis on this, This study presents a method to improve project management for EPC plant project. 'The Work Procedure Matrix for EPC Management' and 'Key Unit Works for EPC Management' were drawn out by using overseas construction management theories and international regulations. In addition, 'The EPC Business Process Management Models' reformed to the Business process method, that is the set of specifications, documents and procedures used to manage the EPC plant project. And it describes how the EPC work procedure manuals will be used. Finally, this study suggests the model of EPC Business Process Management System. The framework of Plant project management can be clarified by using 'The Work Procedure Matrix'. And 'Key Unit Works' are used to organize the work procedure needed to improve plant projects management. The results of this study will help to improve in project management efficiency for plant construction.

In construction project planning and control, a cost model performs a critical role such as cost determination on a contract stage and cost tracing. The model can maximize owner's profit and value within the project budget and optimize cost management works on overall construction implementation stages. A BoQ(Bill of Quantities) generally adopted in a unit price contract has been applied as an important tool for cost control and forecast. However a previous cost model based on the BoQ has shown limitations in that it requires too detailed information and heavy manpower on cost management and difficulty in keeping relationship with construction planning, scheduling and progress management. The each cost items and unit prices which constitute of construction works are individually very important management factors but the relative weight for each items and prices have a difference on the contents and conditions of each conditions of each construction works. In consideration of this structural mechanism of cost determination, this research is aimed at examining the critical factors affecting the construction cost determination and propose and verify a new cost forecasting model which is more simple and efficient and also keeps the accuracy of cost management.
