The information and communications construction business has the characteristics of an infrastructure industry and responsibility for the construction and maintenance of all ICT infrastructures. With the recent proliferation of the smart convergence of various industries based on ICT infrastructure, the role of the information and communications construction business has been highlighted to accommodate the convergence and implementation environment in construction and medical industries. Therefore, this paper seeks policy measures to establish the new role of the information and communications business under the rapidly developing smart convergence environment and the priorities of policy measures to strengthen the capability of the information and communications business using a quantitative model. The analysis result suggests that the difference in importance of each policy measure should be considered in order to execute effectively the policy of promoting the information and communications construction business. Given the constraint of limited budget, policy priorities include the development of new markets, and establishment of incentive for new technology. This study is significant for its theoretical contribution, being the first quantitative approach to policy priorities for the promotion of information and communications construction business under the smart convertgence environment.

This paper aims to make clear the transition process of information transfer in wooden post and beam construction in Japan during the introduction and development of machine precutting technology. The machine precutting technology started from 1970s and developed toward line production or automated CAD-CAM production and have got over 90 % market share in the Japanese newly built wooden houses. Based on literature review and interviews with manufacturers of precutting machines, the transition of wooden post and beam construction houses was divided into four periods: i) before the introduction of precutting, ii) the introduction of precutting (the early stage), iii) the automation of precutting, and iv) the maturity of precutting, and the review reveals how the information of design and processing was made and transfered in each period. In addition, the modeling and comparison of information transfer in each period visually shows the transition of information transfer with the development of machine precutting technology. Before the introduction of precutting, when carpenters were responsible for the generation of both design and processing information, information was coordinated at each stage of the process based on expert knowledge, but highly precise and uniform processing of machine precutting reduced the need for such coordination skills. On the other hand, the review suggested that the precut processing technology has changed step by step based on the traditional technical system, which has maintained the rational transfer of information.

Many pictures are taken at a construction site, but the information of the pictures is not managed in an efficient and systematic manner. For this reason, when a construction worker has scant field experience or knowledge, it is hard to communicate with others efficiently. Therefore, the information of the pictures taken is not fully utilized in any deliberation or conflict among interested parties, facilities maintenance, and construction of another structure, although they were taken for those purposes. This study discusses the need for combining vector-photos with image and 5W and 1H information, and develops a prototype module for creating vector-photos and saving them in a server. The vector-photos taken can be saved to a server in real time, and efficiently managed by a DB system. If a system to link the vector-photos with a BIM model is developed in the future, it is expected that the vector information in the picture can be connected with the property information of an object. As a result, the vector-photos can be utilized in more diverse ways.

Construction workers occupies only $10{\%}$ of the entire industry, but the $30{\%}$ of the critical accidents in whole industry occurs in construction industry. Since there are many dangerous process and lack of safety information measures in the construction industry, both short and long term operation in education, training, and information are necessary. Examples for existing accidents in construction sites will be very useful for preventing accidents. And if the research for individual accidents perfectly achieved, it will give valuable information to construction sites which will be very useful for preventing accidents. The object of this study is to develop construction safety information system to give safety information to construction process by work field. The data base are made from 860 major accidents mostly in buildings and apartments in year 1999 through 2000(KOSHA).

Over the past several years, the building codes that govern commercial building construction have become increasingly prescriptive in nature, specifying detailed information related to the design and installation of the systems, while offering no reasoning behind their prescriptive measures. For example, metal stud framing is commonly used in commercial building construction to create bearing walls and non-bearing partition walls. BIM provides a powerful platform for developing and implementing "pre-planning" tools and methods to facilitate both engineering and administrative controls during construction. This paper discusses the use of BIM to enhance constructability for commercial building construction activities, specifically metal stud framing. Using specific real-world examples this paper demonstrates ways that BIM can be used to foresee potential construction issues and motivates and informs future uses of BIM technologies

Some of the information created during the design phase of an New NPP life cycle is useful only for the execution of the construction phase; however, much of the information greatly impacts the longer-term operational phase. To most make use of design and construction information produced by data based design system during the construction and operation phase, This research is identified controlled data and drawn design information of controlled equipment from documents generated during the life-cycle stages. This study aimed to analyze related documents to assure traceability of controlled equipment from design phase through O&M and then suggested DB(Data Base) based control method on technical information of major equipment throughout nuclear power plant lifecycle.

Underground constructions continue to provide challenges to Geotechnical Engineers yet they pose the best opportunities for development and deployment of advance technologies for analysis, design and construction. The reason for this is that, by virtue of the nature of underground constructions, more data and information on ground characteristics and response become available as the construction progresses. However, due to several barriers, these data and information are rarely, if ever, utilized to modify and improve project design and construction during the construction stage. To enable the use of evolving realtime data and information, and adaptively modify and improve design and construction, the paper presents an analysis and design system, called AMADEUS, for underground projects. AMADEUS stands for Adaptive, real-time and geologic Mapping, Analysis and Design of Underground Space. AMADEUS relies on recent advances in IT (Information Technology), particularly in digital imaging, data management, visualization and computation to significantly improve analysis, design and construction of underground projects. Using IT and remote sensors, real-time data on geology and excavation response are gathered during the construction using non-intrusive techniques which do not require expensive and time-consuming monitoring. The real-time data are then used to update geological and geomechanical models of the excavation, and to determine the optimal, construction sequences and stages, and structural support. Virtual environment (VE) systems are employed to allow virtual walk-throughs inside an excavation, observe geologic conditions, perform virtual construction operations, and investigate stability of the excavation via computer simulation to steer the next stages of construction.

The purpose of this study is to establish a novel system for on-site management of construction and demolition waste. Construction waste has always been one of largest waste in the world and has long lacked an effective management system. Although various countries have planned the disposal of waste at the political level, the real-time and effective management of construction sites has not been mentioned. Especially in China, the continuous development of the construction industry also generates a large amount of waste, and China is not prepared for a large amount of construction waste. In order to alleviate the huge impact of construction waste on society and the environment, this study proposes a waste management method that combines Building Information Modeling technology and Radio Frequency Identification technology. Through this research, by using information technology to manage the generation and discharge of construction waste, and record the amount and information of waste generation, also improve the management method of construction waste.

Many conventional management methods have emphasized the minimization of required resources along the supply chain. Accordingly, this paper presents a proposed method called the Virtual Design and Construction (VDC)-aided system. It is based on object-oriented resource control, in order to accomplish a feed-forward control monitoring supply chain logistics. The system is supported by two main parts: (1) IT-based Technologies; and (2) VDC Models. They enable the system to convey proactive information from the detection technology to its linked visualization. The paper includes a field study as the system's pre-test: the Scaffolding Works in a LNG Mega Project. The study demonstrates a system of real-time productivity monitoring by use of the RFIDbased Mobile Information Hub. The on-line 'productivity dashboard' provides an opportunity to display the continuing processes for each work-package. This research project offers the observed opportunities created by the developed system. Future work will entail research experiments aimed towards system validation.
