When managers predict exact construction cost at early stage and design phase, they can reduce construction cost in a more efficient way than to predict at construction stage. But present of public construction cost estimation and management almost after the construction documents design phase. Therefore, construction cost management in the early stage and schematic design phase to generally use approximate estimating is not correct. Accordingly, this study analyze problem of current cost estimating method and a concrete cost plans make using case information of actual cost to analyze in schematic design phase. Possible to check going on the suitable design, this study conducts the preliminary research for the development of cost estimating model.

Cost and Schedule is the most important information, and how efficiently manage this information is the key issue for Construction Project Management. Domestically, systematic scheduling method such as CPM network is not only used widely but integration of time and cost information also is. In order to effectively integrate and use the time and cost information, it is suggested that WBS(Work Breakdown Structure) based QDB(Quantity Database) should be generated from the design phase and, WBS and QDB related system tool should be supported. It could be helpful to relate and integrate other construction project information.

The purpose of this study is to analyze maintenance costs and estimation of elemental costs for educational buildings. The adapted research method selected four school buildings in seoul region as BTL projects. On the basis of the selected case, the study suggested a model to establish a system for each parts and estimate analyzed construction costs and maintenance costs according to that system. According to the analysis, the study proposed a partial construction costs analysis table and maintenance costs table and analyzed proper construction costs and maintenances costs. The results of this study are as follows 1) The average ratio followed by calculation of partial construction costs of the four school buildings are as followings. The total construction costs is analysed 6,666million won and each part of average rations is structure 47.15%, exterior of building 8.34%, interior of building 23.37%, electricity & fire fighting facility 5.74%, water supply & healthy facility 4.27%, heating & water supply facility 5.25%, landscape 1.36%, civil engineering works 4.51%. 2)The average ratio followed by analysis of partial maintenance costs of the four school buildings are as followings. The total maintenance costs is analysed 4,309 million won and each part of average ratio is exterior of building 11.02%, interior of building 41.81%, electricity & fire fighting facility 14.81%, water supply & healthy facility 11.22%, heating & water supply facility 12.76%, landscape 5.75%, civil engineering works 2.63%.

Inadequate cost management has widely been recognized as one of the most problematic areas in the Korean construction industry as many believes that public cost references are not reasonably reflecting the market conditions. 'Total Project Cost Management Guideline' developed by Ministry of Economy and Finance(MOEF) to govern public budget control has been identified as one of the main reasons for this problem. This study attempts to thoroughly review 'Total Project Cost Management Guideline' itself and quantitatively analyze the impact of it on project cost during procurement process. Different procurement methods are considered including turnkey & alternative, private contract, qualification examination, and lowest price bidding system in this quantitative impact analysis of 'Total Project Cost Management Guideline'. Analysis results shows that this governmental process works mainly as a constant cost-cutting tool throughout the procurement process.

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.

Generally, research on construction cost has been done mostly regarding its direct cost, thus model regarding indirect cost lacks attention. This research seeks to introduce a model to predict on-site overhead cost for apartment construction projects, which constitutes a big portion in Korean construction industry. We devised an equation of 9th degree via curve-fitting, using multiple on-site actual expense data, which can be used to calculate per-progress rate, per-day on-site overhead cost. We further show prospective usage of the model by applying it on construction projects sizing about 30 billion won. Regarding the fact that previous studies could not recognize pattern changes of a total on-site overhead cost, this model is worthy of its conveniency and thoroughness, as well as providing reasonal ground for its derivation in predicting on-site overhead cost of apartment construction projects.

공사비정보와 일정정보는 사업을 관리하는데 있어 매우 중요한 정보로 이들이 연계활용되어야 공정공사비 관리를 원활하게 진행할 수 있다. 그러나 국내의 실정은 공사비가 내역체계 기반으로 관리됨에 따라 설계사에서 작성되어 시설, 부위, 공간 등의 정보를 갖고 있던 수량정보가 내역체계 기반으로 전환되면서 정보들을 상실하고 시공사에서는 다시 물량분개라는 작업을 통해 다시 시설, 부위, 공간 등의 정보를 부여하는 작업이 발생하고 있다. 이에 도로분야 사업을 대상으로 작업분류체계(WBS)를 그 연계방안으로 제시하고 작업분류체계 기반 공사비 작성을 통해 설계사에서 작성된 정보를 시공사에서까지 활용할 수 있도록 하고자 한다. 본 사업에서는 이러한 작업분류체계 공사비 작성을 위한 지원도구 개발을 위해 업무 프로세스 검토, 지원도구 활용 공사비 작성, 시험적용을 통한 지원도구 검증을 수행할 계획이다. 이를 통해 내역정보와 공정정보의 연계가 실현되고, 효율적인 공사비 관리의 기반을 제공할 수 있다.

Early cost estimation promote efficient budget plan by comparing alternatives and presenting cost information However it is hard to predict accurate cost because of vague cost standard and lack of available information in the early stage. The precious cost model has limitations in the accuracy because they are simple linear model which uses the unit cost per kilometer. This study presents the framework of early cost estimation for road construction projects to overcome the limitation of previous cost model. This study analyzed domestic and foreign cost model and cost data of previous road construction project to present method of cost model framework.
