Many construction companies have developed many kinds of information system to integrate the information created in the phase of planning, design, procurement, construction, and maintenance of construction project. However, the previous researches for the state of applying information technologies and the efforts of the analysis of the present information system launched in domestic construction industry is very rare. There also has been short of research on the construction decision-making support theory in construction business and industry. Hence this paper would contribute in identifying the state of information technologies and the theory of decision-making support of the information system in general construction company. and suggest the characteristic model on the information system for the construction decision-making support. The model consists of the two dimensions; (1) organizational hierarchy (2) data analyzing technology. This research, especially, can be expected to initiate the discussion on framework for understanding the construction decision-making support system in construction industry. The model is nut a practical methodology, but a window that offers a new perspective un sources of information system in each construction company, and thus can provide a clue of the useful guide to construction information system development.

It is one of the most important decision making problems to select the adequate foundation practice for the downtown construction project. However the foundation practice has not been selected systematically yet by considering various construction field conditions in many projects. The foundation practice is often informally selected on the basis of only past experiences and skilled engineer's opinion. For making the selection process systematically, in this study, we propose a decision support system (DSS) for selecting foundation practices based on the Analytic Hierarchy Process (AHP) and the Preference Function (PF). In the proposed DSS, the AHP is used for making the selection process more reasonable and the PF is used for considering the decision maker's preference. To validate the proposed DSS, we apply the proposed DSS to the pre-performed construction projects. The application results show that the proposed DSS gives the same foundation practices with the implemented foundation practices that the skilled foundation engineers select after carefully analyzing construction field conditions. The proposed DSS can be used as a useful tool for making decisions to select the foundation practice in the construction fields.

기존의 건설현장은 오프라인에 의한 의사 전달 또는 유.무선 전화 등을 통한 일괄적인 보고를 통해 즉각적인 상황 파악 및 의사결정이 불가능한 제약조건을 갖는다. 이로 인해서 공사기간의 연장, 공사비용 증가, 투입 인력 증대 등으로 인한 부작용이 발생하고 있다. 그러므로 건설 산업 현장에서 발생하는 다양한 예외 상황들에 대해 즉각적인 처리를 하지 못하는 현실적인 문제들을 클라우드 컴퓨팅 환경과 서비스를 이용하여 건설 현장에서 발생 가능한 예외상황에 대한 빠른 보고가 가능하도록 하고, 이를 바탕으로 의사 결정권자가 정확한 상황 판단을 통해 빠르고 경제적인 의사결정을 지원할 수 있는 처리 방법에 대해 제안하고자 한다. 제안시스템은 클라우드 서비스를 이용해 건설현장에서 빠른 의사결정이 가능하도록 함으로써 건설 현장의 정확한 상황 파악 및 효과적인 의사전달이 가능하며, 공사비 절감 및 공사 중에 발생할 수 있는 사소한 견해 차이로 인한 공사기간 낭비도 막을 수 있다.

정보화의 발전은 모든 산업의 시스템화 및 자동화를 이끌어가는 원동력으로 국가 산업에 융복합되어 시너지효과를 발현하고 있다. 이러한 정보화의 일환으로 건축공사의 50~60%차지하는 건설자재의 정보화는 필수불가결한 요소이다. 특히 건설자재의 가격정보는 자재선정을 위한 결정적인 요소임에도 불구하고 현장여건에 맞는 정확한 가격정보를 제공하기에 어려움이 있는 것으로 조사되었다. 따라서 자재선정 의사결정자가 건설자재의 다양한 정보항목을 검색하고, 활용할 수 있는 건설자재에 대한 정보제공 시스템의 필요성과 온라인을 통해 현장여건에 맞는 가격정보 제공의 필요성이 대두 되었다. 이에 본 논문에서는 자재선정 의사결정자들이 온라인 자재정보시스템을 통해 검색한 자재의 현장여건에 맞는 가격정보를 빠르게 획득할 수 있도록 지원하는 견적지원 기능을 제시한다. 이 시스템은 관계데이터베이스를 통해 정보를 저장하고 활용한다. 본 연구는 건설분야 종사자들에게 건설자재선정을 위한 지원 도구로써 활용될 것이며, 이는 최적자재선정을 통한 건축물의 품질을 개선하는데 기여할 수 있을 것이다.

Recent advancement in ICT and IT infrastructure drives the construction industry towards a IT-based industry. Accordingly, the importance of the planning phase of a project is significantly highlighted due to recent large-scale national development projects such as U-city and multifunctional administration city. various development and studies are conducted on the convergence of 3D CAD and GIS in order to support the decision making by simulation of each phase of construction prior to the actual construction of a building. However there has been limits to the implementation of the IT technology in the planning phase due to its characteristics such as high reliability on the experts knowledge and the compliance of the administration work. In this study, a trendy issue of the convergence of the GIS technology with the 3D CAD design data is suggested to improve the efficiency of a decision support in the planning phase.

Recently, as high level of interest for the city regeneration, large-scale projects are planned or being performed such as reconstruction project. These mesa-projects have different characteristics from a single project in the design phase. It is a number of companies involved in design phase of mega-project and principal decision-making entity manage the project from the initial stage of an ongoing business by coordinating an opinions between design companies. The absence of a decision making support system reflected those characteristic causes a variety of problems such as a loss of cost and schedule. Therefore the final object of this paper is to propose a decision making support tool and system interface.

An optimal selection of form-work is very important in the construction project in terms of construction cost and duration management. Also, it substantially affects the quality of the structure and the finishing work. However, in South Korea, the decision making on the selection of form-work has been based on the experience and intuition of construction practitioners not on the objective data or rational decision-making system. In order to solve the problem, several types of research on the selection of form-work has been processed. However, they did not consider the construction site condition, which is one of the most important factors for the selection of form-work. Thus, the objective of this study is developing the objective decision supporting system considering the site condition. This study provides the quantitative decision support model for optimal form-work based on construction site type. It is expected that the decision support model will help the practitioners decide optimal form-work based on the objective data. It will ameliorate the existing decision making process using experience and intuition. In addition, because the model considers site-conditions, it will provide more accurate and appropriate decision on the selection of an optimal form-work.
