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%.

Estimated construction cost is an important index to secure an optimal budget which needs to go into construction projects in the previous of basic design phase. In order for public institutions to calculate the estimated construction cost, the cost per unit area of public buildings is used. However, the current calculation method of the estimated construction cost in public buildings is impossible to reflect the characteristics of many facilities and combinations. The purpose of this study is to develop an estimation model in the previous of basic design phase for the elementary, middle and high school facilities. it is expected that it is possible to estimate the construction cost of the elementary, middle and high schools in a reasonable and reliable manner through the estimation model developed in this study.

As a large portion of defence budget are alloted for military facility construction, reasonable budget estimation in the planning stage has been officers' main concerns. However the proper estimation of construction cost is difficult to be carried out due to the absence of systematic criteria. To improve the budget estimation for military facility construction, this study proposes a cost index model which can convert historical cost to current cost. Thus the developed cost index would enhance effectiveness of budget estimation process 3nd support reasonable decision making. This cost index model is developed by analyzing historical cost data with statistical methodology The study is executed by following process. First, factors which affect construction cost for the most are selected by analyzing historical cost data. second, the selected factors are categorized material cost, labor cost and equipment cost, and weights of those factors are calculated by dividing the cost of each factor by total item costs. Last, cost index is developed by using weighted average method.

In this study, the basic data for calculating the proper construction cost as minimizing the uncertainty at the stage of forecasting construction cost with the basis of the analysis on the actual construction cost within completed domestic public apartment house. In this regard, 23 public apartment houses by each region which were ordered by the Korea National Housing Corporation and completed from 2004 to 2007 were selected as the objects of study. Four works such as common temporary installation, construction work, civil work and machine/equipment work which are the important direct cost items based on the actually inputted and settled construction costs were classified by completion year, region, architectural area, and the distribution type considering inflation rate. The sequent actual construction costs per 3.3m2 were compared and analyzed by each work, the proper construction costs were analogized and the calculating formula were presumed with the basis of average actual construction costs to be analyzed and presented.

The appearance of the large distribution facility of large enterprise putting first reaches get to the various effect until change of leisure life and life pattern of the consumers from the distribution industry of the interior of a country. Competition of the distribution facility upgrade of the distribution facility and it shows the aspect which becomes the semi-department store, and construction cost is appearing different in proportion to each form or scale. Therefore, purpose of this study was to facilitate amicable construction progress between the owner and the builder through estimating the proper construction cost. This study investigated and analyzed the actual cost of 15 domestic distribution facilities and these datums were used to estimate the proper construction cost. This cost shows that from new project accomplishment through analysis of prediction construction cost for feasibility study from initial plan and design step and can be utilizable elementary data bH decision method to whether or not to propriety of distribution facilities business.

The paper considers non-deterministic methods of analysing the risk exposure in a cost estimate. The method(referred to as the 'Monte Carlo simulation' method) interprets cost data indirectly, to generate a probability distribution for total costs from the deficient elemental experience cost distribution. The Monte Carlo method is popular method for incorporating uncertainty relative to parameter values in risk assessment modelling. Non-deterministic methods, they are here presented as possibly effective foundation on which to risk management in cost estimating. The objectives of this research is to develop a computerized algorithms to forecast the probabilistic total construction cost and the elemental work cost at the planning stage.

The case of rivers facilities works, expense the standard unit cost for the quality and a rough public corporation expense estimating of the rivers public corporation which is fixed form with the information available which it follows basic design phase absently and possibility of fluctuation. It exists many difficulties in rough public corporation expense estimating. The rivers public corporation expense rough estimating method of existing produces does not exist the amount of material of representative section of the rivers dike and the rough public corporation expense estimating method which is systematic with the method which multiples the seniority (M). The research sees the rough public corporation expense predictive model from the planning stage which is not basic design to consider the quality of the rivers facility public corporation. From this study, it can prevent the waste of national budget from the general public corporation and is more accurate and public corporation expense production possibly.
