In this study, In order to apply the U-flanged truss hybrid beam to the actual construction site, the structural design of the basic module of the middle and low-rise neighborhood living facilities was performed according to the Korea Design Standard, and the construction cost and construction period were compared with the traditional reinforced concrete structure system. As a result of analyzing the construction cost for the basic module, if the U-flanged truss hybrid beam and D-Deck slab system are used, the construction cost can be reduced by 86% compared to the traditional reinforced concrete structure system. In addition, as a result of analyzing the construction period for a floor area of 1,000m², using the U-flanged truss hybrid beam and D-Deck slab system can save 2.0days in construction period compared to the traditional reinforced concrete structure system. Therefore, the U-flange truss hybrid beam can secure sufficient economic feasibility compared to the existing reinforced concrete method in terms of cost reduction and shortening of construction period.

In the past, social insurance premiums, such as national pension and national health insurance, is contained within the costs of construction projects, have been lowered due to price competition of companies participating in the bidding. The government is implementing the "Ex-post settlement system" to improve the problem. Therefore, the purpose of this study is to examine the concept of an Ex-post settlement system and background of its introduction and to identify problems in the management of the system. The problems of the Ex-post settlement system are: 1) avoiding the participation of construction workers, 2) the rigidity of the insurance premium settlement method in construction field, and 3) the cause of direct construction cost reduction. The ways to improve these problems are: 1) excluding social insurance premiums from construction project cost, 2) securing flexibility of the settlement method of insurance premiums in construction field, and 3) expanding the scope of persons eligible to participate in social insurance.

It is considered that the construction industry is one of the pivotal players in the national economy in terms of Gross Domestic Production (GDP) and employment. Behind the positive role of this industrial sector to the national economy, the construction industry generates approximately 50 % of the total waste generation from all the industrial sectors. There are several measures to mitigate the adverse impacts of the construction waste such as reduce, reuse and recycle. Recycling would be one of the effective strategies for waste minimisation, which would be able to reduce the demand upon new resources as well as enhance reusing the construction materials on sites. The automated construction waste classification system would make it possible not only to reduce the amount of labour input but also mitigate the possibility of errors during the manual classification process. In this study, we proposed an automated waste segmentation and classification system for recycling the construction and demolition waste in the real construction site context. Since the practical application to the real-world construction sites was one of the significant factors to develop the system, a YOLACT (You Only Look At CoefficienTs) algorithm was chosen to conduct the study. In this study, it is expected that the proposed system would make it possible to enhance the productivity as well as the cost efficiency by reducing the manpower for the construction and demolition waste management at the construction site.

Needs of automation and computerization in the construction industry has been recognized but the implementation of e-business solutions with project management systems has not been fully explored. In order to cope with different management practices in home office and project sites, integration of two popular systems, Enterprise Resource Planning (ERP) and Project Management System (PMS) is essential. The objective of this study is to find ways to functionally and systematically integrate ERP and PMS. With the integration of ERP and PMS, a project will be managed much more efficiently and effectively. It is expected that this study will benefit system integrators and help them to understand construction management processes and integrate the solutions with minimized programming work.

Particulate Matter(PM) is one of the most critical pollutant which can cause a fatal disease if the human body inhales. Construction is the business that emits the most fugitive dust. It is therefore necessary to manage construction site. South korea government focuses on the fugitive dust control measures defined in regulation being implemented properly. However the number of civil complaints related to fugitive dust emitted from construction site is the most in korea. So it is necessary to check from the management system aspect. This paper compares and analyzes the fugitive dust management system which applied to the construction site of major cities in three countries, and finds out what needs to be supplemented by the domestic management system.

This study analyzed the development stage and change management necessity of the construction IT system through existing research and literature review, and used WordCloud, one of the text mining techniques, to analyze current construction trends and major issues. The necessity of change management is derived by using existing research literature and construction-related social issues as analysis data.

The purpose of this study is to present a cost classification system that can be used in gas plant construction projects. Towards this end, it examined the detailed statements of the construction companies which had experience in carrying out plant construction projects. Based on the above, it also presented a life-cycle (i.e., EPCC) cost classification system for the gas plant construction projects by conducting the Delphi analysis through the expert opinions.

The purpose of this study is to analysis of counter strategy of greenhouse gas·energy target management system for the construction firm. For this purpose, the greenhouse gas·energy target management system of other industries was investigated. The selection possibility that is construction firm to be managed company was analyzed. In addition, status of counter strategy on the greenhouse gas·energy target management system were investigated and analyzed about 5 domestic major construction firm via questionnaire and interview. As a result, the counter strategy by organization and annual for the greenhouse gas·energy target management system was drawn.

국내 산업 전반에 걸친 정보화 추세는 건설산업에도 예외가 될 수 없지만, 급속하게 전파되고 있는 인터넷의 활용을 통하여 효율적인 건설품질관리업무를 수행하고 있는 건설업체는 몇몇 대형건설업체에 불과하다. 따라서 본 연구는 국내 H건설의 품질정보관리시스템(QIMS)의 구축사례를 알아보고, 이러한 시스템의 활용을 통하여, 향후 건설품질경영시스템(CQMS)이 정착되고 발전되어서 국내건설산업 전체가 국제적으로 품질경쟁력을 인정받는 계기가 될 수 있는 기반을 제시하고자 한다.
