Even large construction projects of nuclear power plant construction and production data is increasing dramatically due to the introduction of ICT technologies, such as 3D scanning technology, wireless communication technology, virtual construction management technology. There are various attributes and types of data to be produced and managed because the documents generated by the contract method are different from the cost processing method. According to the requirements of the international nuclear bid, it is required to present the cost that is calculated based on resource quantity. This research considers ways in which the cost management based on the resource quantity.

Construction data is one of the most important resources in a construction project. The construction data is generally stored in the PMIS. However, it has been analyzed that the PMIS revealed limitations in suggesting valuable information by analyzing the data. In order to overcome such limitations, the linked-data methodology used in big data management has been studied. The purpose of this study is to suggest a methodology that improves the system by developing a more effective data collection and management model using the linked-data format.

The construction cost estimates during the design phase becomes the standard to judge profitability and validity, and is very important in various decision-makings by project owner. However, since approximate costs are quoted when many parts are undecided in the early stage of project, differences are bound to occur between the construction cost calculated through approximate quotation and that put into construction actually. Also, since in existing quotation works, quantity calculations have been dependent on the staff's manual work, involving error potential, and thus differences are likely in quantity calculation depending on the quotation staff's method of calculation. In this study, the process of creating space model to deduce 3D geometry information for approximate quotation in association with knowledge information and the expression for calculation of finishing area were proposed.

The Purpose of this paper is to describe a decision model which can be used to establish an implementation system of renovation for university building. Any implementation model relies on the work scopes of renovation which varies design, project cost, construction duration. The renovation system is subject to evaluation of work steps which is different from each project. Accordingly, the decision model of renovation is necessary to use the application of the analytical hierarchy process. Many of the performance steps used in general renovation condition may be known with uncertainty. This research has shown how probabilities can be explicitly incorporated in the decision model of renovation to assess this uncertainty.

Domestic construction industry is facing big difficulties by a worldwide financial crisis. Especially the deterioration of liquidity by the reject of banks for project financing and unsold housing project made a big problem on financing for the ongoing and new projects. To solve this, it is critical for construction companies. banking facilities and public organizations to cooperate and support each other. In this study, the methods which each part can do are investigated. Construction companies can do a price reduction, finance condition improvement for deposit and down payment, asset sale and cost reduction. And Public organizations can buy the assets of construction companies with proper price and ease the regulation to activate transactions of real estate. In the case of Banking facilities, they can support arrangement and liquidation of insolvent projects and so on.

Today, the form of competition among companies quickly changes in new paradigm. In the past company activity was performed independently, but now dependently. With global age, that change is essential, the introduction of a system that integrates a series of courses is needed for the success of members. Nevertheless, those change are very slow in construction industry, that causes a lot of loss in project process. Construction industry produce structures with collaboration of other industries. There are difficulties that only one company make it, alone. In this trend, cooperation is essential. but the process of original brings a lot of loss From this perspective, this study will prove dependencies of construction industry. Draw out each factor from industrial cooperation, those analyze correlation with system dynamics. In conclusion, this study performs a basic research about 'Integrated Management System' of construction project.

This paper investigated the qualitative introduction status of domestic major construction company. And that focused on a point of suggestions about CM at Risk introduction. The survey analysis showed that three importan suggestions. First, the biggest obstacles factors to CM at Risk introduction that related laws is lagging amendment. Second, we have to improve the available hands ability in domestic major construction company. And last, we have to do that using uncomplicated design and standard design form. Consequently, environmen analysis for the introduction and example project is urgently required.

During the construction project period, a lot of change orders happen in the design and construction stage Especially, The change order during construction stage causes the huge construction cost increase and duration delay. Accordingly, research on the change order of the construction stage is being progressed relatively active in the design stage, but the design changes are rarely made. In the design stage, the owner has to pay a design addition cost when change order due to the demands of owner happens. However Korea has not the specific standard about design additional cost in design stage. Therefore, this study analyzes problems of design additional cost estimation methods through the case study, and then indicates the method that the ratio distributes to details dividing design tasks and the method of the PM(Project Management). Eventually, this study expects to minimize claim related the design additional cost in design stage.

Researches of current PMIS(Project Management Information System) information searching focus on providing personalized results as well as matching needed queries in an enormous amount of information. This paper aim at discovering hidden knowledge to provide personalized and inferred search results based on the ontology with categorized concepts and relations among construction data. The current PMIS searching occasionally presents too much redundant information or offers no matching results from large volumes of data. In this paper, we propose a service searching system, which becomes aware of users device using iPMIS(Intelligent Program Management Information System). And we design and plant the ontology-based iPMIS, which is aware of the context in its environment.

The purpose of this study is to suggest the improved methods for cost sharing in apartment remodeling projects. Case studies on apartment remodeling projects with different plan type were analyzed and compared. Cost sharing estimated by 'proportional rate method' shows similar results estimated by 'return on investment method' in case of similar area ratio of existing plan to remodeling plan. Otherwise cost sharing estimated by 'proportional rate method' shows great differences comparing the results estimated by 'return on investment method'. Although return on 'proportional rate method' is widely used, it is not proper to estimate cost sharing when each householder's contribution for the project varies, such as considerable differences area ratio of existing plan to remodeling plan. Improved cost sharing method is needed taking into account project contribution and characteristics.
