The calculation of the correct construction value in the construction should be investigated after the quantity is calculated. In order to calculate the quantity requires a lot of cost and time, and the initial accurate quantity calculation is not possible. Therefore, in the planning step in order to successfully complete the project to demonstrate the practicality of the difference between the construction cost by the construction design by presenting a method for calculate the quantity through the estimate with the construction open, floor plan, surface view, section.

Looking at current construction costs estimations of publicly declared public works, there are many instances where estimation criteria are ambiguous and doesn't imply the reality. Up to date, estimation criteria for calculating construction cost estimations are simply by unit area multiplication and stochastic construction cost estimation. However, possibility of making errors are high due to using uniform data that excludes each public work's specifications and environmental conditions. Further, on the aspect of cost management, there is certain limitation in the efficiency of cost management in order-placing stage and commencing-work stage; while efficient cost management and reduction of expenses are highly possible during initial stages of the project. In this respect, the paper adopts positive approach with regards to construction cost estimations of public works and draws common elements from calculation tables of the construction cost estimations from 3 completed domestic construction works; after which, the paper analyzes whether business exposition, construction guide and publicly-declared estimated construction costs that the orderer issued are calculated economically and properly; deducing problems in the process, the paper seeks to recommend rational calculation method on this.

The landscape architecture construction cost estimation includes the repeated calculation and updating. Thus, it is time-consuming, and one of the jobs which needs to be automated first. In Korea, the IBM compatible personal computer(PC) is the most widely used one in the landscape architecture firms. However, the software for landscape architecture construction cost estimation is not being used in the PC environment. Therefore, the purpose of this study is to develop the software which can be used to automate the calculation for the landscape architecture construction cost estimation, and runs in the IBM compatible personal computers(PC). The clipper '88 summer is one of the DBMS software packages, and it has many commands and functions and functions which reduces program lines and makes the programing efficient, especially in the programing work whose total source code lines do not exceed over 10,000 lines. So, it was used in this study. The software developed in the this study was tested using the real data, and it was found that it can be efficiently used in the following jobs. They are: (1) to calculate exactly and rapidly. (2) to use resources repeatedly. (3) to print out the results. (4) to store data files for the future use. The software, as discussed in this paper, reduces the time and efforts to be spent in the calculation for the landscape architecture construction cost estimation compared with the traditional approach using the pocket calculator.

The standard for the cost calculation in the field of domestic construction engineering can be largely divided into the construction cost ratio method and the actual cost addition method. However, the standard for calculating the cost of the construction cost ratio method is a trend to switch to the actual cost addition method due to limitations such as not reflecting the characteristics of the construction. Therefore, this study aims to derive implications by investigating and analyzing examples of cost standards in the field of overseas construction engineering, such as the United States, and deriving directions for improvement in domestic cost standards in the future.

The aim of this paper is to calculation benefit cost for development of Hwawon leisure & tourism complex. To calculation benefit cost, this paper propose a advanced travel cost method(ATCM) which is to consider Improved travel cost method(ITCM) and variable traffic units with confidence degree cf decision-maker. At the result of calculation, total benefit costs are 292805 million won at 52% of confidence degrees and 10% discount rates.. Also total benefit cost is 304517 million won at 4% of GDP growth rate is 4%.

To apply more effective the RCM analysis for railway vehicle, the maintenance cost per equipment should be considered together with failure criticality per equipment considered in existing. This paper is described the systematic calculation of maintenance cost considering the RCM analysis of railway vehicle. To calculate the maintenance cost systematically, the cost breakdown structure was established, and basic cost information and calculated cost items were defined. In addition, the linking between calculated cost and RCM analysis was considered. In future, this proposal would be used to analysis of cost effectiveness through RCM analysis of railway vehicle.

The existent system of management for Measurement of Safety Cost are not effective because of the data loss and time loss and occurrence of errors through manual calculation. Therefore, tile development of the software for measurement of safety cost can solve the problem through the systematic calculation for safety cost and converting the related data to database, and also can build the strategy of the investment of Safety cost through analysing and comparing with the past data in the database. As a part of development of the software of Measurement of Safety Cost which is appropriate for the domestic environment, this study is developing a software based on Noguji method, which is one of the methods of Measurement of Safety Cost, and to appraise the efficiency of the management of Measurement of Safety Cost we will implement and improve the software in the case of the domestic enterprises.

Recently, interest in BIM technology has been growing in the domestic construction market as the number of construction projects requiring the application of BIM technology has increased. The use of BIM allows the use of various visualization functions through 3D models as well as drawing interference review, quantity calculation and integrated management of information. In particular, estimates of construction costs based on BIM can increase work efficiency by reducing the burden of calculating construction costs and managing them. In order to increase the efficiency of BIM-based cost estimates, it is necessary to improve the correlation between the BoQ(Bill of Quantity) information and the BIM model. For this purpose, the ratio of the amount and item to the detailed construction of the current BoQ was analyzed, especially the problem of the calculation of construction cost in the window work in this study. In addition, we would like to suggest a method for systematically linking the BoQ information with the BIM model by improving the BoQ information structure of the window work. It is expected that this will increase the efficiency of the quantity calculation and analysis work of construction cost of window work. In addition, it is expected that this method will help to analyze and predict changes in construction cost of windows and doors by facility characteristics and type.

The existing cost calculation standard for the implementation project to manage total maximum daily loads calculates cost by considering the area scale and the population based on the basic cost. This method renders it difficult to calculate cost when the detailed characteristics of a business are considered. Therefore, in this study, we proposed a costing method that applied the standard fee calculation, reflecting the area scale, a number of human and livestock, wastewater discharge facilities, etc. And, through the review of related order cases, the suitability of factors affecting the implementation project is verified and the appropriateness of the cost calculation method is verified.
