원서경,이준복,한충희 한국건축시공학회 2009 한국건축시공학회지 Vol.9 No.6

Recently, overseas construction projects have beenincreasing in the Middle East andSoutheast Asia regions. These projects require various licensesand technologies for the manufacturing and handling processes. Additionally, the efficiency of the entire process management life cycle determines the success or failure of the business. Nonetheless, there exist various risks involved in the whole life cycle process due to a lack of experience and knowledge of management techniques. The objective of this paper is to analyze the business process of a LNG plant throughout the pre-construction and procurement phases, and to identify the knowledge and information needed for the development of the KMS. The study also plans to build a comprehensive knowledge management system throughout the whole life cycle as its final objective. 최근 LNG 수요 증가로 인한 해외 LNG 플랜트 프로젝트의 지속적인 발주 증가로 국내 건설업체의 해외 진출이 크게 증가하 고 있다. 또한 시공 및 사업관리 기술의 발전으로 예전에 비해 고부가가치를 창출할 수 있는 기회가 많아지고 있다. 그러나 일 부 선도기업을 제외한 대부분의 중견 건설업체는 고급 인력과 실무 경험의 부족으로 인한 어려움을 겪고 있는 실정이다. 선진 기업의 경우 체계화된 업무 프로세스 구축을 통해 이러한 어려움을 해결하였다. 이에 본 연구에서는 플랜트 사업의 생애주기 업무 프로세스 중 시공 전 단계를 대상으로 업무를 규명하고 지식관리 항목을 포함한 상세 프로세스를 분석하였다. 이는 전체 생애주기 업무 프로세스를 분석하고 표준화하는 연구의 사전 단계로 향후 지식관리 시스템을 개발하여 통합관리를 하는데 활용 할 수 있을 것으로 기대한다.

건설공사의 초기 단계인 토공사의 경우 현장 토공계획에 부합하는 다양한 건설장비를 활용하여 수행된다. 이 경우 짧은 시간에 다종의 건설기계장비가 투입되며 많든 공사비가 소요되는 만큼 어느 공종보다도 토공관리자의 합리적인 계획 수립이 요구된다. 그러나 대부분의 경우 경험과 직관을 바탕으로 토공장비계획이 수립되어 공정관리 및 원가절감 차원에서 적절한지 검증이 어려우며, 계획수립에 요구되는 고려조건이 변경될 때마다 시간과 인력을 투입해야하는 실정이다. 이에 본 연구에서는 시스템 다이내믹스 기법을 활용하여 기계화 토공장비의 굴삭과 적재 및 운반단계를 대상으로 토공장비의 적정 조합모형을 구축한다. 연구의 결과로 도출되는 토공장비의 적정 조합모형은 토공계획을 담당하는 관리자가 토공장비계획을 함에 있어 짧은 시간에 합리적인 판단을 하도록 지원해줄 것으로 기대된다. The earth work has been improved with the utilization of capital intensive equipments. However, work performance is not satisfactory yet due to its experience-oriented characteristics in selecting the combination of earth work equipments. Therefore, it is required to study on appropriate and systematic methods in selecting a set of equipments for earth work in order to optimize the cost and time as well as to improve the productivity. The objectives of this paper are as followed : (1) developing an optimum combination model of earth work equipments by using a system dynamics technique. (2) testing and evaluating the model by the sample application to a case study. The research is limited to the work of excavating, loading and hauling. The suggested model is proved in practice, so it will assist engineers to make the proper decision for equipment planning of earth work.

There are considerable amount of manpower and time spent for analysis and selection of various materials due to the inadequate application system and rapid searching process of material related information in each stage of building process. Also, due to the insufficiency in recycling system of important information created for each process, they are hoarded at each task stage and project completion. As a result, because of the repetition of the similar/identical tasks on each process, it is the major reason for impeding the manpower and decreasing competition of the company. The construction quality also affects the profit and loss of the product which calls for a need to develop continued information management system that the finish material related examples could be shared in real time. The objective of this study is to propose a building finish material information system which the real time research and application is possible to raise the productivity. To do this, the current material information task analysis and questionnaire research should be conducted to understand the demand of system development and reflect the result onto the system for easy access and application. Therefore, the building finish material information system for enhancement of productivity of construction task is expected to be utilized in enhancement of construction quality, maximization of company profit, and strengthening of company competition.

Recently Gas & Oil plant construction projects are increasing all over the oil-producing countries. The EPC (Engineering, Procurement and Construction) company, which participate in the plant projects, should possess the pertinent engineering license and procurement skill to create high added-value. It is because the procurement is very substantial to cover 70% of the total project cost. Nonetheless, there exist various risks involved in the procurement process due to the characteristics of the construction projects, long duration and complicated processes as well as the procured goods or services subjected to various logistics. The objective of this paper is to analyze proper process in the procurement and to identify various information and document. Also to analyze procurement process, the principal data are derived from the interview with experts and specialty contractors of plant project. The result of this study would widely be used as a guide to the procurement management at overseas gas & oil plant projects.

Large-scale construction projects require various license and technologies for the manufacturing and handling processes. Also, the whole life cycle business process management determines the success of the project. Then, the efficiency of the business conducted by stakeholders and their possessed technology should be enhanced in order to strengthen their competitive power. For this reason, many experts pointed out to focus on the improvement of the life cycle process and efficient management. Since it is very important to keep up-to-date data and utilize it for work during the long-term project to reflect changes in the large-scale project, the most important part of the project management in project is information change management. Therefore, the objective of this study is applying configuration management(CM) technique in order to managing change data generated for planning in early phase. The result of this research will certainly assist the large-scale project managers in the development of information change management system.

It is required to verify construction costs in all phases of construction project life cycle. Especially, the conceptual or approximate estimation is important to assess the project feasibility and budget planning. However, due to limited information and time, there is an issue concerning low-level reliability of the approximate estimating results. The main objective of this research is to provide 3D BIM collaborative approximate estimating model using detailed as-built information of the previous similar projects. In order to achieve the objective, this research builds standardized floor plan database. Space factors and variable factors are extracted from 3D modeling to apply unique characteristics of the project in approximate estimation. The simulation of the suggested model results in a margin of acceptable error range. This research will contribute to visual communication among stakeholders as well as an efficient approximate estimation.
