BIM (Building Information Modeling) is a new paradigm that includes construction life-cycle, and BIM has become mandatory regulation according to the Public Procurement Service since 2016, which accelerates its application. BIM is now expand from architectural field to infrastructure industry. Through pilot projects, BIM has been challenged with verification process. This trend has affected to maintenance and operation (M&O) phase of construction life-cycle. Advanced country has already published their research and result with feasibility study and guidelines. In this paper, we conduct the feasibility study to adopt BIM-based infrastructure management system. Bridges and tunnels were selected as application target, and benefit/cost ratio were used. The result shows that BIM-based infrastructure management system is feasible when the level of detail is more than "Medium" in bridge, and "High" in tunnel.

The demand for promoting industrialization construction methods is increasing in Korea to cope with various construction environments, such as the lack of construction engineers, aging construction workers, and the government's 52-hour workweek policy. The industrial housing accreditation system was introduced in 1992 to recognize and improve the quality of industrial housing, but only six companies are currently certified, and there are no records of constructing industrial houses. Currently, the industrialized housing accreditation system in Korea comprises standards for the recognition, revocation of recognition, and promoting the construction of industrial houses. Therefore, this study analyzed the regulations of the industrialized housing accreditation system, derived the problems of each regulation, and derived improvement directions to promote the industrialized housing accreditation system in Korea. Specific measures include expanding the current industrial housing accreditation scope to quasi (semi)-housing, revising the performance and production standards of industrialized housing, relaxing the building standards, and providing financial support to promote industrialized housing.

3D printing technology is changing the paradigm of consumer-oriented design in supplier-oriented mass production. 3D printing technology in construction is expected to be able to replace existing wet methods along with modular construction. Recently, a number of cases of building construction using 3D printing using mortar-based materials have been announced in many regions, including North America, Europe, and Asia. In this study, we developed a design support tool with a slicing function to output 3D modeling for architecture for a 3D printing machine. We analyzed the process and the function of slicing programs that are commercially available. Seven slicing functions required for the architectural field were derived by analyzing cases, expert reviews, and related literature. The derived functions were extended from the slicing functions to develop the design support tools. Detailed algorithms and processes need to be developed for future derived functions.

Owing to the increase in large and complex construction projects, the design paradigm of architecture and civil engineering projects has changed from 2D CAD to 3D CAD. For this reason, to meet the strong requirements of project contractors, various efforts have been made to adopt a Building Information Modeling (BIM) technology for effective construction management. On the other hand, compared to architectural projects, only a few civil engineering project cases have been conducted in the perspective of public contractors. This is because the characteristics of civil project contractors and the negative pursuit of adopting BIM technology due to the lack of a current BIM system and technologies. Recently, positive changes in adopting BIM technology for public projects were anticipated by public owners, such as the Public Procurement Service and the Ministry of Land, Infrastructure and Transport. In this regard, this study analyzed the current BIM technology status of public owners in Korea to adopt the BIM policies and guidelines of the Korean government. Strategies for adopting BIM technologies for Korean public owners are also discussed based on an analysis of civil engineering BIM project cases.

Knowledge has been one of the key factors influencing the companies' competitive power. Domestic construction industries have introduced Knowledge Management from 1990s around major construction companies. However, construction organizations have recently give a skeptical response about Knowledge Management. The existing Knowledge Management in construction industries does not satisfy the demands of workers. Furthermore it makes workers do double business. Therefore, this study investigates the workers' satisfaction of Knowledge Management, and becomes the preliminary study to suggest how to improve Construction Knowledge Management.

The problem of library space has long been discussed in various aspects such as library relations, architecture, and space design. The purpose of this study is to examine the change of the concept of the complex space of the library according to the development of advanced technology and the social paradigm, and to present the direction of constructing the complex space of the future library by analyzing each case. All concepts such as mediatheque, information commons, larchiveum, and the maker space that is recently introduced into the library are important elements of the complex space presented as a problem of library construction and space. The future library reflects these concepts and serves as a mediator between information and users, users and users, users and media to support reading, information, learning, rest, community-oriented culture and creation, start-up and collaboration. It should be constructed as a multi-space platform to create new value through.

This study is aiming at examining the possibilities to develop eco-friendly waterfront, and discusses characteristics of the organic worldview which has been emerged as new development or eco-friendly paradigm in recent science against the mechanical worldview of modem times. The orientation of waterfront development is characterized as unity, diversity, dynamics and mutuality. In addition, I examined the factors for waterfront design according to the locational, decorativeand visual properties of urban$.$architecture to find out concrete factors of its design. This study suggests the factors for waterfront design making use of organic properties, by examining the orientation for organic development of eco-friendly waterside environment and showing correlation between the factors of specific design, and their examples.

In the AEC(Architecture, Engineering and Construction) industry, BIM(Building Information Modeling) technology not only helps design intent efficiently, but also realizes an object-oriented design including building's life cycle information. Thus it can manage all data created in each building stage and the roles of BIM are greatly expanded. Contractors and designers have been trying to adopt BIM to design competitions and validate it for the best result in various aspects. Via the computational simulation which differs from the existing process, effective evaluation can be done. For this process, a modeling guideline for each kind of BIM tool and a validation system for the confidential assessment are required. This paper explains a new process about design evaluation methods and process using BIM technologies which follow the new paradigm in construction industry through complement points by an example of a competition activity of the Korea Power Exchange(KPX) headquarter office. In conclusion, this paper provides a basic data input guideline based on open BIM for automatic assessment and interoperability between different BIM systems and suggests a practical usage of the rule-based Model Checker.

Recently, the paradigm of SOC investment has shifted from new construction to maintenance. This shift became more important for the highway system because it is as one of the most important SOC. In Korea, highway maintenance costs are about 20% of the total annual highway construction budget, which is about two-thirds of developed countries. In addition, establishing standardized guidelines for the highway maintenance operation is not in place. Therefore, in order for domestic road construction and maintenance technology to secure competitiveness in the global construction market, it is urgent to improve the management capacity for maintenance as well as the technology and management capacity. This study examines highway maintenance practices in OECD countries such as North America, Europe, Australia, New Zealand, and Japan to identify core elements of highway maintenance practice. It is imperative to establish a comprehensive management system based upon asset management principle. Even if the budget for the highway construction is reduced, investment in maintenance needs to be maintained.

Recently, the BIM paradigm in domestic and foreign countries has been recognized as a momentum that can enhance productivity, efficiency, and collaboration of work in the construction industry. In this aspect, some countries have driven the development of BIM guideline to introduce and apply the Open BIM which is IFC-based BIM. Whereas, introduction and application of the BIM in Korea has been tried partly by several government agencies, public companies, design and construction companies. To promote the proliferation in the BIM use, therefore, the guideline needs to be developed first of all than anything else. In this context, this study addresses the trends of the BIM guidelines of foreign countries and strategic directions necessary for developing the Open BIM guideline.
