  • An efficient demolition process requires the optimum method selection considering stability, economic feasibility, environment, and workability. In reality the construction cost and period are priority concerns, and safe construction methods are neglected. In addition, the choosing demolition method is often determined subjectively by experienced field engineers. This research paper presents a multi-criteria decision-making method using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to select the optimum demolition method. Three experienced demolition engineers' opinions were used to develop the TOPSIS model. The case study showed that the preferences of ten attribute measurements for demolition method selection. Authors suggested the most preferable demolition method for the case study project.

  • 리모델링은 기존 건물을 폐기하지 않고 재활용 함으로써 자원의 재활용이라는 측면과 신축과 같은 부가가치를 창출한다는 측면에서 매우 중요하다고 할 수 있다. 그리고 공사에 적절한 공법 선정은 공사비와 공사기간을 줄여주고 품질을 향상시키는 역할을 한다. 또한 리모델링 공사의 경우 현장의 특성과 구조체의 특성이 공사시에 큰 영향을 끼치기 때문에 기존 신축공사 보다 공법선정이 매우 중요하다고 할 수 있다. 그러나 현재의 공법 선정은 시공정보를 반영하지 않고 단지 기존에 주로 사용하던 공법만을 선정하고 있다. 그렇기 때문에 본 연구에서는 공법 선정시 의사결정을 도와주기 위한 tool의 구축 방안을 제안한다.

  • Globally the interest of large-scale structure has been increasing for the use in various social and cultural events. However various problems for building large-scale structure in South Korea are expected in terms of construction method and site management due to the lack of experience. Construction method and planning significantly affects on making decisions. There are only theoretical approach for constructing large-scale building in domestic with the limited experience of constructing constrained size structure. Through Analytic Hierarchy Process with experts, derived decision factors mostly used construction method in construction of large-scale structure. Derived factors from this study will support making decisions for field management in constructing large-scale structure.

  • Recently, the items of construction planning have magnified and specialized and the problems occurring at the first step of the construction planing process have complicated. In this research, AHP(Analytic Hierarchy Process) method which is simple to apply and clear to decide has been proposed when a people making a plan at the first step of the construction planing process. As an example, the best solution has been obtained in a railway construction line choice that consist of various items by applying for this method, which proves the possibility of application of this method to the complicated problems.

  • Since variety of construction projects with their individual specifications could be handled through different procurement systems, selection of the most appropriate project delivery system is a vital step towards more efficient project execution. The appropriate selection of project delivery system may also ensure more competent management of the project. Its impacts are not only limited to the first stages of the project, as it could also influence pre-construction, construction and operational phases of the project. Among different approaches exerted for this purpose, none has taken uncertainty into account, despite the fact that during first stages of the project most of the selection factors are still uncertain and not clearly defined. This paper, hence, aims to provide a fuzzy insight into the project delivery system selection. Through this approach more tangible model of the evaluation process may be presented. Proposed fuzzy method is indeed a multi criteria decision making model, based on the group of criteria, assigned for the evaluation procedure. A case study is also conducted, based on the opinion of an invented group of the experts.

  • 고층 주거건축물 공사에서 적합한 거푸집의 선정 여부는 프로젝트의 성패를 좌우하는 중요한 요인이다. 그러나 현재 국내 고층 공사는 거푸집별 특성을 고려한 적합한 거푸집 선정이 이루어지지 못하는 실정이다. 합리적이고 체계적인 거푸집 선정을 위해서는 공사비뿐 아니라 공기, 품질, 안전 등을 포함한 종합적인 고려가 요구된다. 따라서 본 연구에서는 공사비, 공기, 품질, 안전측면에서 거푸집 선정에 대해 계층분석적 의사결정(AHP)의 과학적 방법론을 제시하여 거푸집 선정 프로세스를 과학적 방법으로 합리화 하고자 한다. 이를 위해 국내 고층 주거건축물에 사용된 거푸집 현황을 조사 후 이를 토대로 거푸집 대안을 선정하고 공사 전문가들을 대상으로 거푸집 선정 시 관리 우선순위 및 거푸집 적용성에 대한 설문조사를 실시하였다. 본 연구 결과는 고층 주거건축물 거푸집 선정 시 기존의 비과학적인 방법을 보다 과학적이며 합리적인 의사결정에 기여할 것으로 판단된다.

  • The process of selecting a repair material is a typical one of multi-criteria decision-making (MCDM) problems. In this study Analytical Hierarch Process was applied to solve this MCDM problem. Many factors affecting a process to select an optimal repair material can be classified into quantitative and qualitative requirements and this study handled only quantitative items. Quantitative requirements in the optimal selection model for repair material were divided into two parts, namely, the required chemical performance and the required physical performance. The former is composed of alkali-resistance, chloride permeability and electrical resistivity. The latter is composed of compressive strength, tensile strength, adhesive strength, drying shrinkage, elasticity and thermal expansion. The result of the study shows that this method is the useful and rational engineering approach in the problem concerning the selection of one out of many candidate repair materials even if this study was limited to repair material only for chloride-deteriorated concrete.

  • 2018년 국토교통부 통계에 따르면 재건축 연한이 도래한 주거용 건축물은 2018년 기준 약 37%에 달한다, 해체물량의 증가는 해체산업의 성장과 함께 환경 및 안전사고 등 많은 부작용을 일으키고 있다. 이에 본 연구는 해체공법 선정에 있어 안전성, 경제성, 환경성 등을 종합적으로 고려하여 현장 적용에 가장 적합한 공법 의사결정 방법을 제시하고, 특히 해체공사의 안전성을 고려하여 현장 공법 적용 시 위험요인에 대한 사전평가를 통해 공법선정뿐만 아니라 선정 공법의 현장 적용성을 평가한다. 이를 위해 본 연구는 QFD 기반의 TOPSIS 해체공법선정과 FMEA 위험성평가 통합모델을 제안한다.
