  • The construction road work are increasing now. And the domestic slope construction are steadily increased and changed the complicated and large-scale. Therefore ground reinforcement for slope stabilization has been increasingly used during the past few decades with a wide variety of techniques including soil nailing, rock bolt, anchor and different types. But in some cases which applied slope reinforcement construction by badness or mistake. So this paper is the study of construction badness for slope reinforcement.

  • Recently, it has been a worldwide issue to develop offshore wind farm based on the past technical experiences of onshore wind turbine installation. In Korea, the government has the wind-energy to be a new-sustainable field of development to bring green-growth in near future and put political and fiscal efforts to support the academic and industrial technical development. Especially, there are much advancement for the fields of turbine, blade, bearing, grid connection, ETC. Correspondingly, technical needs do exist for the offshore foundation installation techniques in geotechnical point of view. Within few years, 2~5MW offshore wind turbines will be constructed at about 30m water depth and it is known that monopiles of D=4~6m are suitable types of foundation. In order to construct offshore wind-turbine foundation, technical developments for drilling machine, design manual, monitoring&maintenance technique are required. This paper presents technical issues with related to offshore wind farm and large diameter monopile in the point of renewable energy development.

  • A temporary work are lifting equipment that tower crane or lift, and temporary architectures that office building and storage in construction site. And it is main construction work that built and used temporarily like to a scaffolding, a walk plate, and a formwork. This study is to adjust breakdown structure of temporary work to introduce technical tendency. With a site manager, it is collected a detailed statement and compared. As a result to break down a tendency that temporary equipment, additional function, and direct work of temporary technique, first, existing detail technical indexes that group I, group J, group K, and group L are classified. Second, due to set up and manage to main agents in case of existing detail technical indexes that B1, B2, it is not wrong to classify. But, it is somewhat different, and therefore adjust it to same level. Finally, as a technical tendency that temporary equipment, additional function, and direct work of temporary technique, it is adjusted the others.

  • Failure occurred slope, due to typhoon 'Rusa' and 'Maemi' last two years, was studied to evaluate the slope failure characteristics. There're three types of the slope in this study, ie. soil slope, rock slope, mixed slope. Statistical analysis was used to estimate the relation between slope type and failure mode. Among the failure occurred slope, soil slope & mixed slope are dominant at the ratio of 33%, 44% respectively. We conclude that soil slope & mixed slope have more higher risk than rock slope during heavy rainfall.

  • The existing design materials by document type are restricted in searching and acquiring necessary design information because the materials consist of huge information and various document types. This study suggests a methodology to develop an electronic technical manual that can manage construction design materials by XML-base integrated information system. Electronic technical manual for design materials can provide visualized information through various multimedia tools such as multi-link, virtual reality and animation. Using an integrated electronic manual for construction project can prevent to miss necessary design information. The results of this study includes a data flow diagram to develop an interactive electronic technical manual (IETM) for construction design information. Finally the study suggests some scenarios for practical use and quantitative analysis of application effect analysis by AHP method.

  • With the recent acceleration in the adoption of IT in industries, converged Construction-IT has been drawing attention as a new market driver in the IT fusion industry. Despite the simultaneous implementation of U-Cities all over Korea in a manner suiting each city's own attributes, Technical Criteria to build an optimized IT-infrastructure have not yet been prepared. To solve this problem, a standard for U-City construction should be prepared. This research, therefore, draw sample contents in order to establish and verify the criteria for U-City construction. The findings are expected to be meaningful, in that they would serve as significant data for establishing the criteria for future U-City construction.

  • There are big differences between developed countries and Korea regarding to the circumstances of electrical installation construction. In other words, Korea, in spite of its small market size, has large pools of electrical construction companies or associated workers, and there are a lot of poorly electrical construction companies in domestically. Thus, in reality, it is difficult to invest in technical development to enhance Korea's technical level on electrical installation and companies are likely to construct as occasion demands instead of constructing in a technical manner. Therefore, the government needs to develop a standard specification as a guideline for stable, economical and technical electrical installation construction. With this standard specification, almost all electrical construction companies could practically use it and also could guarantee their construction quality as well. It is important to induce small companies to utilize the standard specification to secure their construction excellent quality so that the life of the nation, individual's properties and national properties could be well protected.

  • Recent demands from construction industry have emphasized the capability for graduates to have improved skills both technical and non-technical such as problem solving, interpersonal communication. To satisfy these demands, problem-based learning that is an instructional method characterized by the use of real world problem has been adopted and has proven its effectiveness various disciplines. However, in spite of the importance of field senses and dealing with real problem, construction engineering education has generally focused on traditional lecture-oriented course. In order to improve limitations of current construction education and to satisfy recent demands from construction industry, this paper proposes a new educational approach that is Failure-Based Learning for using combination of the procedural characteristics of the problem-based learning theory in construction technology education utilizing failure information that has the educational value in the construction area by reinterpreting characteristics of construction industry and construction failure information. The major results of this study are summarized as follows. 1) Educational effect of problem-based learning methodology and limitation of application in construction area 2) The educational value of the information on construction failure and limitation in application of the information in construction sector 3) Anticipated effect from application of the failure-based learning 4) Development and application of the failure-based learning conceptual model.
