The purpose of this study is to suggest a model for evaluation of a risk based value index for modular design alternatives in plant construction projects. Accordingly, 1) Setting the basic project cost and the scope to apply the module, 2) Evaluating the importance, easiness, and effectiveness index for Engineering, Procurement, Fabrication, transportation, and construction work, 3) Estimating the total project cost by analyzing the risk reserve Step, 4) Comparing the effectiveness index and total project cost for each modular design alternative, it was composed of the steps of deriving RVI. To verify such a model, Plan-A, which applied a module to one process, and Plan-B, which applied a module to three processes, were composed to evaluate RVI.

대한설비건설협회는 지난 2월 26일설비건설회관 대회의실에서 제38회 총회(정기)를 개최하고 2008회계년도 사업계획을 수립했다. 2008회계년도 사업계획은 지난 1월 1일부터 일반·전문간의 겸업제한이 폐지되었으나, 기계설비공사업종만 4년 유예됨에 따라 유예기간 동안 △설비건설 발전을 위해 협회 역량을 집중하고, △새정부의 공공공사 예산 절감방안에 적극 대처하기 위해 계약제도와 원가제도 보완을 추진하며, △정부위탁업무를 신속·정확히 처리하여 회원사의 이익과 편의를 도모할 방침이다.

The construction duration in apartment construction is an important factor which affects project cost. Henceforth, the time shortening is essential to retrench project cost and project risk when there adopt Five-Day Workweek and introduce apartment sales after completion of construction. Therefore, the purpose of this study is to examine closely the affecting factors on the duration of framework which forms about $40\sim50\$ percent of total time in apartment construction by analyzing the schedule mechanism of typical floor and to show the reasonable time shortening methods by case study. The shown schedule mechanism and basic schedule table can utilize as a guideline in case of scheduling of framework in the existing construction method. Also, the shown time shortening methods by three case studies will guide the direction and process of time shortening while there need time shortening in many-sided projects.

While growth of domestic CM market has slowed down due to economic recession, it recently shows sign of scale as some public agencies are relocating their headquarters. Since the introduction of CM system, a number of client organizations have acquired construction project management capabilities, however, sufficient efforts are not made to estimate the size of construction project management organization. This study drew a method for estimating the size of the organization managing construction project by utilizing statics analysis and project costs per member based on 10 public construction projects and tried to review applicability through case studies. With this study, we would like to make a contribution to achieving smoother work performance and success of the construction project by estimating and allocating proper scale of management workforce.

Road construction projects have a long duration so cost overruns and schedule delays are occurred. However, performance assessment system that can manage and prepare for this in advance is insufficient. In addition, road construction are affected by many factors during under construction. Therefore it is necessary to conduct performance assessment considering the characteristics of roads and prepare for similar projects in the future. The purpose of this study is to provide a framework to evaluate construction phase performance and present a performance management plan using road construction information. Also, This study conducted time adjustment between the start and the finish of the project and developed performance metrics based on absolute and relative indicator. This study analyzed the cost, schedule, and changes of the road project construction process, showing the possibility of advancement of performance assessment and how to use it when planning new road construction projects.

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.

국내 건설행정 투명화 및 경쟁력 향상 목적으로 개발된 건설사업정보시스템에 정부와 운영주체는 다양한 기능개선 방안과 관련 연구를 수행하며 시스템 성능을 개선시켜왔다. 그러나 기 추진된 성능향상 방안이 공공업무 처리에 중점 되어 대국민 사용자를 위한 콘텐츠 및 기능 등의 서비스가 미흡한 상황이다. 이에 본 논문에서는 건설사업정보 건설인허가시스템의 도로점용장소별 허가현황 기능을 중심으로 빅 데이터를 이용한 허가현황 정보 제공 방안을 제안하였다. 제안한 기능개선 방안은 기 구축된 비정형 데이터를 빅 데이터 기반으로 재분석하여 구글 맵에 가시화함으로써 공공업무 데이터 처리 뿐만 아니라 대국민 서비스를 위한 콘텐츠 제공이 가능하도록 하였다. 뿐만 아니라 그동안 축적된 15TB이상의 건설관련 데이터의 재활용 가능성을 시사함으로써 시스템 활용성 증대 및 개편 방향에 도움이 될 것으로 판단된다.

Predicting accurately the construction cost budget in the early stages of construction projects is crucial to support the client's decision-making and achieve the objectives of the construction project. This holds true for public construction projects as well. However, the current methods for predicting construction cost budgets in the early stages of public construction projects are not sophisticated enough in terms of accuracy and reliability, indicating a need for improvement. The objective of this study is to develop a construction cost budget prediction model that can be utilized in the early stages of public building projects using an artificial neural network (ANN). In this study, an artificial neural network model was developed using the SPSS Statistics program and the data provided by the Public Procurement Service. The level of construction cost budget prediction was analyzed, and the accuracy of the model was validated through additional testing. The validation results demonstrated that the developed artificial neural network model exhibited an error range for estimates that can be utilized in the early stages of projects, indicating the potential to predict construction cost budgets more accurately by incorporating various project conditions.
