  • There are certain types of construction that produces many defects during the construction of apartment buildings. It may be due to construction errors in the type itself, but more often, it is due to defects derived from other types of construction. Thus, to reduce such secondary defects and prevent fundamental defects in particular types of construction, academic research on the types of construction causing secondary defects should be actively conducted. In addition, as claimed in this study, the industries should work harder to improve the quality of the type of construction that causes secondary defects, rather than just trying to improve the ostensible problems. If the efforts of each sector are backed up, the disputes over defect repair in apartment building construction will reduce in general, which in turn will lead to a reduction in national loss within the construction industry.

  • Major construction projects will be directly related to construction costs and disclosure period depending on the selection of the construction method. However, there are some sites that choose without taking into account sufficient conditions. Therefore, the company wants to present a quality model that suits the characteristics of major engineering fields.

  • Currently, various studies and applications related BIM based quantity take-off have been attempted, because of the accuracy of cost estimating and reliability by using the BIM model information in automatical calculation. Finishing works that have a large number of various types and materials need the higher accuracy and reliability on the BIM-based quantity take-off. Therefore, this study compared and analyzed 2D and 3D based quantity through Test-bed and determine the cause of the quantity difference. This verified the accuracy and efficiency in the BIM-based quantity take-off for finishing works. Also this study has been proposed opinions for calculating the exact BIM-based quantity take-off.

  • As the construction industry has been increasingly complex, aging workers, hard-working avoiding young generation, foreign workers having language problem for the past decades, delivering of construction qualified workers has been a rising problem. This misalignment between the complex jobs and the number of skilled workers will continue to be in issue that the construction industry will face for following decades. Construction field workers who are working outside in uncontrollable condition unlike manufacturing industry are exposed to easily construction safety accident. There are so many efforts to prevent and control the construction accident. However, the relationships between the construction works and construction safety accident has not been well dealt and investigated based on objective accident data except for the qualitative study through interview, delphi and so on. Therefore this study analyzes job risk matrix exposed to safety accidents based on statistic data for 20 years from Korean Occupational Safety & Health Agency in order to prevent the construction field accidents.

  • Research on the "Modernized Korean traditional housing" (Hanok) has been actively studied in succeeding to Korean traditional housing and providing the public with housing that required for modernized life style. The purpose of this study is to classify work sections for Hanok specifications. This paper analyzed the concepts and characteristics of existing specifications. It was found that the absence of standard classifications is one of the causes of missing work items and mixed scopes. Also, the contents of carpentry works have low level of details. Therefore, Hanok specifications, in this study, are required to have upper level standards and to encompass traditional and new construction methods. Further research will develop standard classifications, standard codes, and automated systems of Hanok specifications for improving quality and effectiveness.

  • The existing defect management is focused on step before closing work, a builder preliminary research and tenant preliminary research. Each step is not related. And the existing study on defect management mainly classify into work type and defect type according to work type. This study divide into defect part. Also this study propose PDA based web and 3DCAD for improving method of existing defect management.

  • 표준품셈 487개 항목이 제·개정됨에 따라 건설공사의 예정 가격이 전반적으로 하락할 전망이다. 특히 올해 새로 도입될 표준품셈 상시관리시스템이 작동하면 내년 표준품셈 개편폭은 더욱 확대된다. 건설교통부는 지난 1월 4일 기계설비 등 5개 공종에 걸친 487개 표준품셈 항목을 신설·개정했다고 밝혔다. 이번 개편의 특징은 기존 기관별 요구사항을 단순 반영하는 것이 아니라 건교부가 직접 목표량을 설정해 직접 발굴했고 기계설비, 토목터널 부문이 집중 개선된 점이다. 기계설비 부문의 경우 밸브 및 콕류, 신축이음쇠, 잡철물, 방열기, 위생기구, 소화전 등의 항목이 대폭 개정됐다. 이번 개편에 이어 전체 표준품셈 2,460개 항목 가운데 503개 항목이 추가로 조정돼 내년 초 공표된다. 특히 표준품셈 상시관리시스템이 올해 상반기 가동되면 내년 초 공표될 항목은 이보다 더욱 늘어날 전망이다. 정부의 시스템 운용방침이 당초 계획된 2개년 목표치(990개 항목) 외에 추가 항목을 발굴하는 것이기 때문이다.

  • 대한설비건설협회는 지난 1989년 협회 창립 이후 설비건설업계의 영역확대를 위해 분리발주를 숙원사업 중 하나로 정하고 그 동안 관계기관에 건의하는 등 끊임없는 노력을 기울여 왔다. 우리협회의 이러한 노력에 힘입어 대한주택공사를 비롯한 정보통신부, 교육인적자원부 등 주요 발주처 및 발주기관에서 분리발주를 시행하고 있다. 최근들어 기계설비공사는 단순한 기계설비에서 벗어나 쓰레기이송설비, 지열냉난방시스템 등 최첨단 기술을 접목한 다양한 시공으로 확대되고 있다. 이 과정에서 업역에 대한 확고한 규정이 없어서 설비•일반•전문건설업자간 치열한 밥그릇 싸움이 예상되고 있다. 따라서 대한설비건설협회는 이러한 신규분야가 우리 설비건설영역이 될 수 있도록 더욱 박차를 가할 계획이다. 또한 지난 5월 17일 공포된 건설산업기본법 개정(안)에는 2개 공종 이상의 소규모 단순복합공사는 전문건설업자에게 원도급을 허용하는 조항이 들어있다. 이로써 오는 2009년 7월 1일부터는 소규모 단순복합공사의 경우 전문건설업자도 전문면허를 복수로 취득하여 원도급 공사 참여 가능하게 됐으며, 분리발주와 동일한 효력을 갖는다. 본지는 앞으로 분리발주 확대를 위한 각오를 새롭게 다지기 위해 대한설비건설협회의 분리발주를 추진 과정 및 분리발주된 공사현황(10억원 이상, 2002년부터)을 살펴본다.

  • Currently, the Korean Smart Construction Corporation aims to stimulate overseas expansion of smart construction technology centered on Expressway development. In addition, the integrated classification system of construction information with Work Breakdown Structure(WBS) is currently being established in Korea, but its application to the construction industry is limited. In this study, data generation using simulation is carried out at the lowest level of WBS presented by the Korea Expressway Corporation, and detailed process productivity is predicted by site conditions.
