  • Stakeholders of a construction project expect cost savings through fast and accurate cost analysis by performing BIM-based quantity take-off (BQT). However, authors have observed that there can be discrepancies in the results of BQT depending on the level of development (LOD) and modeling methods. In addition, since quantity take-off methods are different depending on the construction work items, the combination of LOD, modeling methods of BIM, features of construction work items can cause serious overestimate or underestimate in BQT results. It is necessary to identify what kind of problems can happen and how those problems can be avoided in various construction work items, since the discrepancy of quantity take-off results has great impact on not only cost analysis but also the determination of contract amount and it can cause claims, poor construction quality, cost overruns, and many others later in the construction project. Therefore, this paper focuses the identification of issues and problems of BQT at each construction work item level based on two categorizations of structural works and interior works.

  • 해체공사는 건설행위에 의해 건립된 건축물의 수명이 평균 22년 이상 경과한 후에 시행되는 후행 건설공종이다. 90년대 이후 해체대상물이 고층화, 대형화됨에 따라 그에 대한 중장기적인 대비가 없었으며, 해체산업 관련 제도나 법 등이 체계적으로 마련되어 있지 않았다. 본 연구에서는 국내 해체공사 안전관리 관련법의 개선방안을 마련하고자 3가지 법령 개선(안)을 제안하였으며 그 내용은 다음과 같다. 첫째, 건설기술관리법의 안전관리계획 수립에서 해체공사 대상의 기준에 대하여 방안을 제시하였다. 둘째, 산업안전보건법의 해체공사표준안전작업지침의 문제점을 보완한 개선방안을 마련하였으며, 셋째, 건설기술관리법의 안전관리계획과 산업안전 보건법의 유해 위험방지계획의 중복성에 대한 통합화 방안을 제시하였다.

  • Daily workers in construction sites rarely receive the benefit of systematic safety and health training as they are required to move from one construction site to another in response to the start, completion, and repetition of construction works. Also, small- to medium-sized construction sites often lack the capacity to train their workers. Therefore, as in the advanced countries, basic safety training system for construction workers should be conducted in the industrial-level, rather than in individual workplace-level, to make the training more effective. By doing so, only workers with the basic safety training will be able to engage in construction works. Consequently, accidents in the construction industry will decrease, as workers themselves who are at the forefront of the construction worksites are empowered to play the central role in accident prevention activities.

  • Construction works of civil infrastructure projects generate a considerable amount of carbon emissions by utilizing a set of energy-intensive equipment and causing traffic congestion. However, the voluntary efforts of the contractor to mitigate these emissions are at an early stage. To address this issue, this paper explores the opportunities to take carbon emissions that would be caused from construction works into consideration in contracting methods and procedures. The opportunities for reducing carbon emissions from construction activities themselves are examined under the framework of Performance Contracting for Construction (PCfC), and carbon emissions from traffic congestion are attempted to be incorporated into the Road User Cost (RUC) calculation. This paper also identifies and discusses major challenges that must be confronted when considering the mitigation of these emissions in contracting methods and procedures.

  • 최근 공동주택의 주거 비율이 높아짐에 따라 이에 따른 하자분쟁이 증가하고 있는 추세이다. 이러한 하자들 중에서도 마감공사는 발생빈도가 가장 높으며 이를 보수하기 위한 막대한 비용이 발생한다. 그러므로 이러한 문제를 해결하기 위해 하자 발생빈도 및 보수비용을 활용한 하자위험도를 미리 도출하여 하자순위별로 사전에 예방할 수 있는 관리기법의 개발이 필요하다. 따라서 본 연구에서는 공동주택 마감공사의 하자유형별 분석 및 위험성 평가 방법을 도출하는 것을 목적으로 한다. 이를 위해, 최근 준공된 마감공사 하자사례를 조사하여 하자위험 우선순위를 도출하고 하자관리를 위한 위험성 평가방법을 제시하였다. 본 연구의 결과는 공동주택 마감공사의 품질향상을 위한 관리제도 개선의 근거자료로 활용될 것이다.

  • In the field of domestic construction demolition works, work process management system is left behind compared with that of several advanced countries such as US, Japan and UK. Especially, the problems regarding safety management are more serious in terms of the availability of safety manuals and law system. The analysis results fiom the questionnaire survey and interviews with demolition engineers indicated that current safety management practices in demolition works lack systematic approach and inappropriate in securing labors' safe working environment. In addition, field labors and managers strongly requested the improvement of safety educational system. Grounded upon the analyses results and investigations, suggestions were drawn for the establishment of advanced safety educational system.

  • Appropriate management of the finish works in construction project is one of most important activities that must be conducted considering the total duration of the project. Masonry work is a fundamental process that is performed in the preliminary steps of finish works. However, it has been investigated that the analysis of delay factors affecting masonry work has been neglected in the domestic construction site. Therefore, this study deducts delay factors affecting masonry work by literature review and survey on site engineers and labors. This study has been conducted as a preliminary step of developing a construction project interference management system which is expected to suggest objective information for the decision making in construction sites.

  • Construction schedule plays a key role in project management due to its influence on the project success. Thus, it is important to identify factors affecting construction delay. The major objective of this study is to identify and evaluate factors affecting construction delay in apartment projects in Vietnam. The findings confirmed that financial difficulties of owners and contractors, contractors without adequate experience, non-available materials on time, slow site clearance, inappropriate construction methods, defective works and reworks, and lack of capable owners/project managers are the major causes of delay in apartment projects.
