A construction project's period is limited by the order manufacture. And a construction project is requested a specific place, and has the characteristic to be irregular. Today, construction is to be representative high-cost and low-efficiency. This kind of problems appears in small construction projects more often than large construction projects. According to this facts, we recognized necessity of making practical application in methods of construction management. Also, we suggest application and establishment of integrated responsibility management department, PMIS(Project Management Information System) and Data Base. From now on, methods of construction management could be good opportunities for small construction projects and local construction companies. Therefore, small and local construction companies should try to improve their abilities. Likewise, the countries systematize to constitute the relation laws.

Although various IT-based services including PMIS are used at construction field, there have been limits on communications, such as fast reaction, information loss, and information security in the real world. Therefore, this paper proposes to adapt a social network service (SNS) that has already been used for information management and sharing information at the company level in other industries in order to support construction information management and communication in a fast and accurate manner. Following the requirement analysis through literature review and site interviews, the paper presents an SNS-based construction information communication and sharing system named PMIS+. PMIS+ was tested and validated for its feasibility at construction sites and it was proved that the proposed system and information management framework using the system could be helpful for effective information management at construction fields.

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.

For the purpose of automatic management and enhancing quality of construction, information technology has been employed in construction field recently. As a consequence, informative construction, which utilizes information technology to reduce construction time and optimize construction sequence, becomes a state-of-art field of construction. Considering this case, construction field should more actively adopt other engineering technologies of rapidly advancing fields, such as electronic, control, and informative engineering, in order to reduce construction cost and to solve environmental problems as well as to enhance construction quality. In this aspect, this paper introduces a novel research field 'Geo-mechatronics', which stands for the convergence of geotechnical engineering and mechatronics (i.e. automation of mechanics using electronic technologies). Since the ground is ubiquitous in every infrastructure construction, the Geo-mechatronics research is crucial for the development of construction technology in the future. Moreover, it is believed to that the Geo-mechatronics research will make our construction industry to be more future-oriented and internationally comparative industry.

The performance of the construction project is to be evaluated within 60 days of completion, according to relevant laws. It evaluates cost, construction period, design change, re-construction, safety, etc. for each project stage. And the project owners are inputting the evaluation results of the construction work into the construction project information system(CALS). The post-evaluation result information entered in this way can be referred to in the basic design of the construction project by referring to the related contents if there is a similar construction in the future. And It can also be used to predict and respond to the required period and cost by analyzing the accumulated data. In this study, in order to provide reference data that can be used in similar projects in the future, the latest analysis methods are reviewed and the possibility of future application is considered. Accordingly, this study intends to focus on the construction cost part among the indicators such as construction cost, construction period, design change, and re-construction that are currently being dealt with in post evaluation.

영국, 일본은 전후복구를 위해서, 미국, 호주 뉴질랜드는 경제부흥에 힘입어 1960년대부터 사회기반 인프라의 건설을 계속 확대해 왔다. 1990년대 들어와서는 인프라의 노후화가 가중되면서 인프라의 기능을 보존하기 위한 비용이 급격히 상승하고 있다. 이들 나라는 최소의 유지관리 비용으로 사회기반인프라의 보존이나 교체시기 연장을 위한 방안으로, 1990년대 중반부터 자산관리 체계를 개발하고 있다. 한국도 경제 부흥을 위해 1980년대부터 사회기반 인프라를 집중적으로 건설하였다. 그 결과, 2010년대 후반부터 유지관리 수요가 급속히 증가할 것으로 예상되고 있다. 하지만 자산관리 선진국에 비해 우리나라는 초보적인 수준에 머물러 있다. 그래서 본 연구는 미국, 영국 뉴질랜드에서 제시한 자산관리시스템의 모듈기능과 구성을 비교분석하여 한국 실정에 적합한 사회기반인프라의 사전 예방적 유지관리를 위한 자산관리시스템 프레임워크를 제시하였다.

최근 건설 산업이 고도화, 지능화됨에 따라 건설자재정보의 효율적인 관리방안으로 RFID 기술을 이용하려는 연구 및 적용 사례가 증가 하고 있다. RFID(Radio Frequency Identification)란 라디오 주파수를 이용한 무선인식 기법을 뜻하는 것으로 건설자재에 RFID Transponder(이하 태그)를 부착하여 생산, 유통, 설비 등 전 과정의 정보 추적 및 관리가 가능하다. 그러나 RFID 시스템 특성상 전자기장이 형성되는 철골자재나 수분이 포함된 콘크리트, 도료(안료) 등의 자재에서는 RFID 적용이 쉽지 않다. 또한, 현재 사용 중인 RFID 장비마저도 표준화 되어 있지 않고 사용 주파수 대역 또한 각각 다르기 때문에 건설자재에 적용하기위한 RFID 시스템의 표준화 및 규격화가 절실하다. 본 논문에서는 건설자재에 RFID를 적용하기 위한 표준화 방향을 제시하는 기초 연구로써 목재, 철재 빔, 도료(안료), 콘크리트, 배관자재(철/동/PE)에 Passive Type의 일반(Pager) 태그, 금속 태그, 액체형 태그를 부착 매립하여 125KHz, 13.56MHz, 900MHz의 주파수 대역과 자재 물성별 인식거리 및 인식률 시험을 진행하여 건설자재에 RFID를 적용하기위한 표준 주파수 대역 및 재질에 따른 적정 태그를 제시하고자 한다.
