In evaluating the competitiveness of construction companies and their development strategies, patents are a useful and objective source of technical information. In this study, the cutting-edge technologies of construction industries of China, Japan, and South Korea were investigated based on the data of patent applications filed by a total of 15 construction companies (five companies from each country). The related technologies were classified into six core technology groups based on their keywords. After that, we used four patent analysis methods: time series analysis, IP (Intellectual Property) emergence level analysis, spiral module analysis, and OS (Object-Solution) Matrix analysis, to identify the promising technologies/vacant technologies for global construction companies in China, Japan, and South Korea, and to analyze the technical competitiveness of the three countries. The findings of this study showed that each country can claim a relative technological advantage over the others. Overall, 3D printing and offsite construction technology, data acquisition technology, AR and VR technology are expected to be promising in the Asian region. The present study contributes to the body of knowledge by expanding our understanding of technological innovation for the competitiveness of companies and the technology development strategies pursued by the construction industries of China, Japan, and South Korea.

This paper is to suggest strategic options for improving the export performance of the plant and construction industry. The overall objective of this study is to explore the feasibility of a sustained export performance in the plant and overseas construction industry by an analysis of its international competitiveness and technological competence. The empirical work of this study relates to a chosen sample of Korean and non-Korean firms in the plant and construction industry sector. Primary data was collected through a comprehensive questionnaire survey administered to plant and construction firms in twelve countries, including Korea. The actual number of firms for which full information at a sufficient level of disaggregation was obtained was 62, a response rate of 44.6％. Of these, 42 firms were drawn from Korean plant and construction firms and the remaining 20 firms from 11 other countries. The structure of responding firms by industry shows a total of 29 plant exporters and 33 construction firms. Data analysis was carried out using SPSS statistical technique such as Multiple Regression in order to examine the linear relationship among variables. The findings of the study indicate that export success and failure in plant and construction export markets is determined by firm size and by various qualitative variables. The high export volume (export success) of Plant and construction exporters is more strongly influenced by mutual economic cooperation and number of employees than by sales volume and competent knowledge of the plant and construction markets. It was also found that weak political and diplomatic relation between countries, low sales volume and lack of bid experience have an adverse effect and represent serious barriers to exports.

There is growing difference between a planned value and an actual cost for increasing as an risk of construction cost. A construction cost index is an alternative to redeem a problem, but it is still very difficult to reduce an actual differential as a price fluctuation. Furthermore an existing theory of a construction cost index is overly complex, and is unsuitable for using in working-level. This study suggests an optimum correction rate in respect of a total construction cost. It is analyzing the actual cost of 53 public buildings that the Public Procurement Service ordered. The objects are main processes that include architectural works, mechanical works, electrical works, telecommunication works, and service facilities. It is compared a total construction cost based on absolute error rate using the median from frequentist principle. For this, it is selected the suitable regression model and set a correction rate.

Considering the similarity in legislation and long-term industrial trend of Korea and Japan, continuous attention to the Japanese situation is useful for the development of a domestic construction strategy. In order to compare the current on-site construction management practice of the two countries and analyze the reasons for discrepancy, a literature review, expert interview, and site investigation were executed. A detailed survey of experts with experience in both countries revealed that overall, Korea's level of competitiveness is gaining on that of Japan. However, the Japanese construction industry was still evaluated as maintaining higher competitiveness, due mainly to comprehensive planning for operation, well-established design documents, and effective total quality safety environment management, all of which are combined with institutional support and a cooperative attitude by labor. Adjustments should be made for advanced technologies considering the attributes of a typical Japanese construction prior to establishing and implementing application strategies according to the suggestion of experts. Based on the results of this study, a benchmarking of Japanese strength should be conducted, and this is eventually expected to contribute to establishing green construction, enhancing safety, improving culture, and reinforcing the capabilities of participants.

Enterprises should set up realizable goals and continually control the goals from apprehending whether they can be realized or not so that the enterprises grow consistently. Furthermore, from supplementing parts to be improved, goals are reset and the result should be controlled in order to fit to them. Lately, a lot of discussions about the results of organizations, projects, and companies are being realized in construction field. Particularly, in construction management, effective and professional control activities throughout the life cycle of facilities as well as the stage of business implementation of construction work are needed. About the result measurement of the construction management, lots of most domestic researches stay in the level of establishing basic concepts. Also, since characteristics of the construction field and the construction management were not reflected properly, it is in a situation that the result control system is not applied to on-site real works. Hence, this study intends to suggest fundamental data for measuring objective results from extracting result areas and key performance indicators of the construction management using Balanced Score Card.

Purpose: Looking for the root cause of a construction accident leads to the problem of unreasonable construction costs and air setting by the person placing an order. In addition, low-cost bidding by a contractor with insufficient capacity is combined, creating an inappropriate construction structure that can cause an accident before the start of construction. Method: Analysis of the problem that the lack of original contractor resources in the construction environment is passed on to suppliers, and the phenomenon that partners and their workers are forced to push ahead with excessive work to secure a minimum margin. Result: Going back to the root of construction accidents, there are several dimensions of causes from physical phenomena to root causes, but the reason why accident prevention measures so far remain almost at the one-dimensional level of responding to the phenomenon is the lack of fundamental cause analysis. Conclusion: It is necessary to shift the paradigm to safety accident measures led by the client (the client) and the government, and construction accidents are reduced only when root cause of construction accidents is found through fundamental cause analysis techniques such as 5Why.
