The development and utilization performance of the construction new technology was introduced in 2014 according to the detailed evaluation criteria of the construction project of Ministry of Land, Infrastructure and Transport. In the case of the construction new technology, the current standard is give 3 points in the "technology development and investment performance" evaluation item. However, construction engineering companies is difficult for to invest the capital required for new technology development. Therefore, in this study, we try to extract the difficult factor that occur in the process of construction new technology development in terms of construction engineering companies. The research results are expected to provide with the support policy guideline for new technology development costs to policy makers.

Recent Construction and Transportation R&D projects are larger in size, investment scale has been increasing rapidly. However, the results of Construction and Transportation in R & D are papers, patents and other results. So, the application record of R&D in the construction field is very lacking. In particular, Construction New Technology's ratio in the midst of R&D's results are about 2.29%. Therefore, this study suggested program that R&D's results has been connected Construction New Technology. The introduction of the new system has greatly increased Construction New Technology and the results of excellent &D will be applied in construction field. So, Cost-reduction and technology's improvement are expected.

This study analyzed the performance of new construction technology in construction site. The main results are as follows. First, 83.6% of the new technologies developed by SMEs(joint development by large enterprises) account for the majority. Second, new construction technology is mainly applied to construction and civil engineering, but it is mainly applied to four major types of work(waterproofing, soil and foundation, reinforced concrete, bridge). Third, the number of on-site applications with a construction value of less than 500 million accounted for 89.5% of the total, which indicates that new construction techniques are mainly applied to small-scale construction.

Purpose: The construction of New Han-ok style public buildings is a construction that can not be seen in traditional Han-ok, and it is a construction that combines traditional wooden structure, RC structure, and steel structure. Therefore, construction different from general construction is complicated and complex. It is necessary to accurately understand the construction method of each field rather than the general construction management method and study the method suitable for New Han-ok style public buildings. Also, since the New Han-ok style public building business is the first business to be introduced in Korea, new process management is needed rather than general process management. Method: The research method is as follows. Analyze process management through theoretical considerations and analyze the differences from general construction projects. Next, we want to identify the characteristics and problems of the process control method applied to real cases. Finally, the results of this analysis suggest ways to improve process management. Result: Therefore, it is necessary to establish a precise plan from the basic design to the construction of the public building construction management. In addition, careful planning should be made so that the supply and demand of materials and the supply and demand of personnel can be achieved smoothly.

국내 건설신기술제도는 건설업계의 자발적인 기술개발을 유도하여 국내 건설기술 수준 향상 및 경쟁력 강화에 기여하였다. 특히 건설신기술의 현장적용으로 공사비 절감 및 공기단축의 성과를 달성하였다. 그러나 건설신기술제도가 도입된 지 33년이 지났지만, 건설신기술의 매년 지정건수와 건설현장 활용실적은 정체 수준이다. 따라서 본 연구는 건설신기술의 현장활용 저해요인을 다각적으로 분석하고, 현장활용 활성화 방안을 제안하였다. 주요 결과는 건설신기술 활용실적 모니터링 제도 도입, 특정공법심의 기술위주의 평가, 건설신기술 사후평가시스템 개선, 건설신기술의 기술마켓시스템 등록체계 구축, 건설신기술의 활용실적 관리방안을 제안하였다. 이러한 제도개선은 건설신기술의 현장활용을 촉진할 것으로 기대된다.

우리나라는 1989년 기술개발자의 개발의욕을 고취시킴으로써 국내 건설기술의 발전을 도모하고, 국가경쟁력 등을 제고하기 위하여 건설신기술 지정제도를 도입하였다. 국내 건설신기술제도가 1989년 최초 도입되어 2009년 12월 31일까지 총 596건의 건설기술이 신기술로 지정되어 건설현장에 총 3만여회 이상 활용되는 등 양적 성과를 거두었고, 국내 건설산업에 직 간접적인 영향을 미치고 있으나, 건설신기술제도의 도입 효과에 대한 체계적인 분석은 이루어지지 않고 있다. 이에 건설신기술제도 도입 이후 건설현장에 활용되었던 양적 성과 외에 건설산업에 직 간접적으로 영향을 미친 경제적 파급효과를 정량적으로 분석함으로써 동 제도의 운영에 따른 당위성을 확보하고 우수성을 검증하여 동 제도가 향후 지속적으로 발전할 수 있는 기틀을 마련할 필요가 있다. 본 연구는 건설신기술 사용으로 인한 공사비절감액, 공사비절감으로 인한 타 산업 비용절감효과, 취업유발효과, 부가가치 유발효과, 수입대체효과 등 건설신기술의 경제적 파급효과를 정량적으로 분석하였다. 이러한 연구결과는 건설신기술의 경제성과 우수성을 널리 홍보하고, 활용촉진을 도모하는데 활용할 수 있을 것이다.

This paper presents the results of a three-dimensional numerical investigation into the effect of new tunnel construction on structural performance of existing tunnel lining. A three-dimensional finite difference model, capable of modelling the tunnel construction process, was adopted to perform a parametric study on the spatial variation of new tunnel location with respect to the existing tunnel with emphasis on the plan crossing angle of the new tunnel with respect to the existing tunnel and the vertical elevation of the new tunnel with respect to the existing one. The results of the analyses were arranged so that the effect of new tunnel construction on the lining member forces and stresses of the existing tunnel can be identified. The results indicate that when a new tunnel underpasses an existing tunnel, the new tunnel construction imposes greater impact on the existing tunnel lining when the two tunnels cross at an acute angle. Also shown are that the critical plan crossing angle of the new tunnel that would impose greater impact on the existing tunnel depends on the relative vertical location of the new tunnel with respect to the existing one, and that the overpassing new tunnel construction scenario is more critical than the underpassing scenario in view of the existing tunnel lining stability. Practical implications of the findings are discussed.

A construction temporary work is main process and importance trade section. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study reviews literature researches and can verify that changes to a comprehensive technology system for construction site. In addition, it suggests a breakdown structure of new standards for temporary construction technology based on views of construction site managers. Meanwhile, temporary construction technology in Korea has changed with a specification of construction temporary work which had been revised in 2014. However, the revision is merely dividing the design and building off of construction temporary technology. It is lacking in many ways to change this in a new standard system for temporary construction technology. Henceforth, it needs to develop a standard system for temporary construction technology and a professional system that is appropriate for different purposes by detail trade sections.

Past research shows that the construction of new infrastructure accelerates economic growth in the region by attracting more people and commodities. However, the previous studies only considered large-scale infrastructures such as sea-cross bridges and channel tunnels. There is a paucity of literature on regional infrastructure and its impact on socio-economic indicators. This paper explores the impact of new bridge construction on the human population, particularly focusing on regional bridges constructed during the 2000s in the state of Georgia. The human population at a county level was selected as a single socio-economic factor to be evaluated. A total of 124 cases were investigated as to whether the emergence of a new bridge affected the population change. The interrupted time series analysis was used to statistically examine the significance of population change due to the construction by treating each new bridge as an intervention event. The results show that, out of the 124 cases, the population of 67 cases significantly increased after the bridge construction, while the population of 57 cases was not affected by the construction at a significance level of 0.05. The 124 cases were also analyzed by route type, functional class, and traffic volume, but the results revealed, unlike large-scale infrastructure, that no clear evidence was found that a new bridge would bring an increase in the human population at a county level.
