The building construction projects include a variety of risk factors due to uncertainties. To succeed in the projects, it is important how risks are managed. Risk management processes identification, analysis and response. Especially, the analysis process is important to objectively identify importance and priority among risk factors. The purpose of this study is to develop the effective analysis process by studying and supplement the problem of the AHP analysis method. The study provides a analysis process to use the PROMETHEE analysis method proposed.

The reason why most scheduling softwares currently using at construction projects adopt PDM (Precedence Diagramming Method) is that it can express an overlapping relationship between activities. However, the overlapping relationships in PDM are represented only by combinations of four overlapping types that connect the start and finish points of two activities, therefore, PDM cannot express efficiently the relationships between any middle points of two activities if they should be represented. This research proposes the method of transforming the four overlapping types of PDM to the overlapping relationships of BDM(Beeline Diagramming Method), new networking technique, that can connect the inter-relationships at any middle points of two activities as well as express multiple overlapping relationships. The proposed method will help not only to improve an efficiency of scheduling but also to upgrade the scheduling technique because BDM technique has a lot of unique advantages in scheduling.

건설재난을 줄이기 위한 정부의 노력에도 불구하고 건설기술진흥법의 안전관리비가 실제 현장을 반영하지 못한다는 지적이 제기돼 왔다. 따라서 건설사고 예방을 위한 가장 근본적인 대책으로 삼을 수 있는 안전관리비의 적절한 가이드라인을 연구할 필요가 있다. 또한 합리적인 안전 관리 비용을 확보하기 위해서는 적절한 비율을 계산하는 것이 중요하다. 따라서 본 연구에서는 안전관리비 실행계획에 따른 공사비 및 유형별로 적정 안전관리비율을 제시하였으며, 그 비율은 산업안전보건관리비의 10분의 1로 분석된다. 본 연구결과는 적정 공정등급제 개선 및 시범사업 추진에 대한 지침이 될 것이다.

Labor work information can be converted into the useful construction information in an effort to analyze project status, measure performance, and design a new similar project plan. The labor work information can also be used to make productivity data, which can be used to analyze the relationship between 'as planned' and 'as built' in scheduling management of a project, and to calculate 'percent completion' as well as analyzing delay cause. It is require to effectively collect the labor work information base on the activities. In general, current project management heavily depends on the experience and judgment of project managers, according to the work progress. However, relying on the oかy experience and judgment of the project managers might deteriorate the transparency or reliability of the collected labor work information. The purpose of this research is thus to develop a computer-based system for monitoring the work information generated by labors input in activities using PDA and Barcode technologies, and to propose a application method of the productivity data for effective project management.

Generally speaking, it is important to know the activities itself exactly and to control the activities correctly so as to assure timely progress and the quality of any project. In order to progress smoothly in accordance with construction schedule, it is important to systematize the preliminary arrangements necessary for each process and then manage them. In this study, in order to progress smoothly the quality and schedule management of the construction, we can be made systematically pre-works in accordance with construction schedule by the civil construction items of the apartment house construction. we suggested pre-construction control item by the workers through experiential method of construction engineers in accordance with network schedule.

The required level of detail in scheduling depends on the stages in the construction life-cycle. The objective of this study is to provide a Standardized Schedule Model (SSM) with an aim to facilitate the estimating of construction duration in the planning stage. The SSM modularizes work items; establishes relations between preceding and succeeding activities; and calculates approximate construction duration. The estimated duration of the SSM was compared with the detailed duration from the commercial scheduling tool using actual work activities. The difference showed to be ranged between -3.1% and +15%, which demonstrates that the SSM can be feasibly applied to the approximate estimation of construction duration.

건설현장관리에는 설비관리$\cdot$공정관리$\cdot$품질관리$\cdot$원가관리$\cdot$노무관리 등이 있는데 흔히 생산성향상과 원가 절감을 목표로 하는 공정관리와 원가관리의 목적을 달성하기 위해서는 안전관리는 어느 정도 무시되어야 한다고 생각하는 경향이 있다. 그러나 안전관리도 마찬가지로 원가의 절감을 지향하고 생산성 향상을 목표로 하고 있어 제반관리와 분리될 수 없다.(중략)

In 2012, Korean overseas construction market has achieved 64.9 billion dollars of contract order and its amount has increased since the mid 2000's. However, importance of qualitative growth based on profitability as well as quantitative growth is also emphasized. This study analyzed overseas plant project's subcontract process management which is closely related to cost management as one of the qualitative growth methods. In order to select major subcontract processes, extensive literature review and focus group interview(FGI) were implemented and then professionals with years of experience in the overseas plant projects were participated in the questionnaire survey. The collected data were analyzed by Benefit-Structure Analysis(BSA) model. The findings of this study include: (1) the seven and six subcontract processes are positioned in the area of importance control factor and in the area of maintenance/control factor, respectively; (2) administration capability attainment is needed for the six subcontract processes in the area of importance control factor and sustainable management system is required for the processes in the maintenance/control factor area. The further research will identify key subcontract processes to be managed for overseas plant projects by Korean EPC contractors based on the findings of this research.

In a construction project, process planning is an important factor in determining the success or failure of a project. In particular, it is necessary to systematically establish a process plan in the early stage because the finishing work of an apartment house involves more interference than the foundation work or the frame work. First, in this study the problems of Tact process management were identified, Based on the data from the case project, conventional Tact process management and compositive Tact process management were compared and analyzed. Second, cost analysis was performed on applicable plastering work to suggest the necessity and direction of compositive Tact process management. Third, the appropriateness of manpower according to the number of construction households is analyzed through cost analysis. Through this, the validity and effectiveness of compositive Tact process management were verified based on the results derived from this study.
