  • In recent, many Korean contractors have tried to extend their business area into the overseas construction market, mainly as a result of a reduction in their domestic construction market. However in terms of risk, overseas construction projects are likely to face a number of unpredictable problems, many of which occur as a result of differences in contract cultures and construction environments between Korea and other countries. One key issue facing overseas construction projects in particular, is that of sub-contracting and control, and the way in which many countries of Commonwealth of Nations operate a unique subcontracting method well known as a nominated sub-contractor(NSC). This paper introduces the NSC system and differences as comparing among standard construction contract forms, such as JCT, SIA, HKIA and PAM. in UK and Asian Commonwealth of Nations. Also, we attempt to classify the type of the NSC system through the consideration of NSC clauses in accordance with the objection and termination of NSC contracting respectively.

  • In the Chinese construction industry, the utilization of Building Information Modeling (BIM) aims to increase the total output of the construction industry by solving the problem of inefficient interoperability in the construction industry. In 2011, the Chinese Ministry of Housing and Urban-Rural Development despite the technical advantages of BIM and the government policy, the BIM adoption rate in China is lower than 45%. Meanwhile, as the South Korean construction industry is a step ahead of its Chinese counterpart in introducing and utilizing BIM, it is expected that BIM is more actively utilized and accepted in South Korea than in China. According to a comparative study based on the hype-cycle theory, South Korea is at a more advanced stage of introducing BIM, than in China. This study aimed to suggest how to increase BIM utilization rates in China. To this end, this study comparatively analyzed factors affecting BIM acceptance between China and South Korea. For the comparative analysis of the BIM acceptance factors between China and South Korea, literature reviews on the technology acceptance model (TAM) and BIM acceptance model were carried out, and based on that, the BIM acceptance factors were classified. Other BIM acceptance factors were also added and considered, as they reflected Chinese national characteristics and construction industry. As for the derived BIM acceptance factors, construction project participants, especially actual BIM users in China and South Korea, were targeted for the survey. A t-test using SPSS 22.00 was carried out to identify significant differences in data. Finally, based on the t-test results, this study suggested ways of improving the BIM utilization rate in China. Based on the findings, this study is expected to contribute to activating BIM adoption in the Chinese construction industry and also to set a theoretical foundation for future studies on BIM utilization in the industry.

  • Lean Construction recommends implementing site production management by measuring the reliability of daily production tasks, collecting the causes for failure of incomplete tasks, and identifying problems in the existing process based on the collected data. Although many research projects have been performed to introduce Lean Construction in Korea, there are not many cases in which day-to-day site production operations has been stringently evaluated based on such methods. This paper introduces three cases in which such techniques were implemented on a residential, civil infrastructure and plant project. On each project, process maps were created with the superintendents and daily production meetings were held for two weeks. Consequently, the average PPC for the three projects was 79% for PPC and 16% for PAT. In addition, the majority of the failures were due to 'Directive/Plan' and 'Prerequisites.' The results show that project stakeholders (owners, contractors, etc.) lack the ability to plan ahead and keep to their plans, and also lack the capability to synchronize workflow between themselves. The results also reveal that project participants need to be more proactive in solving process problems on site and also need to be better educated in Lean concepts and methodologies.

  • Construction companies are trying to apply process management to their business to improve efficiency in business circumstance of high competition and globalization. Since 1990s, construction firms adopted process management to improve internal and external business structure based on process. It however has a few improvement functions. In addition, business support systems for business process efficiency improvement were developed, but separation between business process and IT system occurred because it focused on function-based individual construction and data input/output. To solve this problem, this study proposed business process and IT integration model for supporting user to use business information and system based on visualized business process and improving use of previous business support system. Business efficiency is expected to be improved with this model which based on integration required business condition(stakeholder, business data, functions of business supporting system). This study developved process model, architecture, and BPA of whole construction management business. According to BPA, it analyzed business process stakeholder, detail activities, and input-output data. And also it examined 12 main business supporting system of Korean construction firms. Based on analyzed data, this study developed business process supporting integration model based on business process through PDCA and CRUD analysis.

  • This article analyzes biographies of women participants in Miryang struggle against 765㎸ transmission tower and finds that the experience of state violence under the ideological conflicts works the biographical context of participation in environment movement. The cases analyzed in this article disclose the family member's experience of state violence and their trauma through the participation in social movement. And they legitimize their family member's life, heal their trauma, and live a new life by the social movement participation. But the power of healing trauma comes from solidarity and support in social movement. Findings of this article imply that experiences of state violence have influence on the formation and development of various Korean social movements and we need more solidarity and democracy for healing the trauma occurred by state violence and concealed in individual memory. Findings of this article also suggest the importance of biography documents. Biography documents can contribute to widen and to deepen understandings on the social interaction and social history, because they are the document about people's experience who are excluded from the official history and character culture. Moreover biography documents can compensate the official documents, because they can offer the context to the social actions in the official documents. More accumulations and analyses on biographies can serve to widen and to deepen understanding and explanation of Korean society having multilayered exclusion in the process of the compressed modernization and the history of national division.

  • The purpose of this study is to suggest a systematic procedural model for selecting competent project promoter. The proposed model was made by comparing domestic regulations and procedures with foreign nations', and through interviews with experts and literatures survey. The summaries of this paper are as follows. The current promoter selection procedure was evaluated by reviewing relevant papers, regulations and existing model. Some obstructions which hinder PPI project activation were identified, those are inadequacy of promoter qualification and negotiation process, lack of communication between parties, etc. Some alternatives which remove major obstructions are embodied in the model. The suggested model is comprised of PQ(prequalification), two phased evaluation for the technical proposals which include alternate, communication meeting, etc. To manage the overall procedure well, an involvement of professional "project promoter selection team" would be highly recommended. They will participate in each evaluation stage with full activities, and provide government with some technical materials for selecting promoter as coordinator.
