This study proposes additional items to be recognized as defects in a defect lawsuit through a case analysis of lawsuit cases in apartment housing. Identifying these defects prevents an unexpected increase in litigation costs, delays in the date of litigation, and emotion repercussions or additional lawsuits. In this study, the defects that were not discovered by the existing occupants and construction companies, but were newly discovered in litigation, were defined as defects in lawsuits. Fifteen cases of lawsuits were analyzed and a total of 77 defects were derived. Each item was then reviewed for location, work type, number of occurrences, and cost. The results were yielded 23 defect items, which were validated by appraisers who directly appraised the cases. In addition, the derived defect factors were analyzed. Finally, the 23 defect items were categorized into 10 main factors which include attributes such as causes of occurrence and characteristics. This can provide an overall area of defects to be considered in addition to existing defect items in the life cycle of the housing. The results of this study can contribute to reducing the actual occurrence of defects and minimizing the disputes in the case of defect lawsuits.

This research addresses the types and causes of defects in seismic retrofitting projects of school facilities, which, following the Gyeongju and Pohang earthquakes in September 2016 and November 2017 respectively, have been identified as having comparatively lower seismic resilience among public buildings. The incidence of seismic retrofitting has notably increased in the subsequent years, raising concerns about the potential for defects arising from these efforts. The government has committed to enhancing the seismic resilience of all public facilities by 2035, with a specific focus on completing upgrades for educational establishments by 2029. Although prior investigations have explored construction defects in school facilities, there exists a gap in research specifically targeting defects within seismic retrofitting processes. Thus, this study aims to catalog the defects associated with seismic retrofitting efforts and analyze their underlying causes to identify crucial management strategies for defect mitigation. Furthermore, by examining the interplay between defect types and their causative factors, the study seeks to pinpoint essential management practices that could preempt defects during the construction phase, ultimately aiding in the reduction of future maintenance expenditures.

하자발생은 막대한 보수비용과 함께 업체의 이미지와 신뢰성을 실추시키는 한 요인이 되고 있다. 따라서 설비건설업계는 가급적이면 하자발생률을 최대한 낮추기 위해 노력하고 있다. 건축물에서는 특히 공동주택, 주상복합건물에서 하자발생 빈도가 가장 많다. 설비건설업계 A업체의 경우 고급아파트 주거시설의 하자비가 전체의 78%정도를 차지하고 있는 것으로 조사되었다. 이 업체의 경우 지난 3년간 평균 매출액 대비 0.58%의 하자가 발생되어 경영에 어려움을 가중시킨 것으로 나타났다. 따라서 하자가 발생되면 업체 경영에 어려움은 물론 이미지 손상이라는 큰 타격을 주기 때문에 업체들의 하자발생을 방지하기 위한 노력이 절실하다. 월간 '설비건설'은 설비건설업계 하자 중 제일 많이 발생하는 공동주택 하자발생 현황을 조사하여 기획특집으로 마련함으로써 향후 하자발생 예방에 대한 지표를 제시코자 한다. 이번 호에는 설비건설업체들의 하자발생 현황을 게재하고, 다음 호에는 전 건설업 중 설비건설 분야의 하자발생 현황 등을 게재할 계획이다. 업체로서는 하자발생을 내놓기 꺼려하는 부분이기 때문에 본지는 업체명을 게재하지 않았다. 자료를 선뜻 내놓기 쉽지 않았음에도 불구하고 기꺼이 자료제공을 하여 주신 업체들에게 감사의 뜻을 전한다.

하자발생은 막대한 보수비용과 함께 기업의 이미지와 신뢰성을 실추시키는 한 요인이다. 따라서 설비건설업계는 가급적이면 하자발생을 억제할 수 있는 공법개발과 함께 정밀한 시공으로 하자 발생율을 최대한 줄이기에 역정을 두고 있다. (주)우원(대표 김영호, 임종태)은 그동안 공동주택에서 발생한 하자사례를 모아 분석한 자료를 내놓았다. 이 자료를 토대로 유의하여 시공한다면 하자발생을 최대한 줄일 수 있을 것으로 보여진다.

Characteristics of Contactor's Defect Liability was too many discussed. But it's not clearly defined yet. Because recent Government Construction Projects are very complex and executed through long time, too many conflicts were appeared related to Contactor's Defect Liability. Therefore to analyse and to resolve the conflicts legal aspects of Contactor's Defect Liability stated in Civil Law and Government Contract Act was systematically compared. The result of this research is as follows : (1) Characteristic of Contactor's Defect must be regarded as a breach of Contract and be an incomplete contract implementation. (2) To decide the range of Damage, Characteristic of Defect must be regarded. (3) Contactor's Defect Liability must be effectual from the day of delivery. (4) Retainage must be added to secure the completion during the Contract Period and Defect Repairing Liability must be omitted in the Contract performance Security.

Recently construction companies expand position for apartment house in construction market because of house supply rate increase and its amount. In addition, because the focus of house sale market has moved to customer from supplier, the importance of defect management is being issued currently. However, current apartment defect management is not satisfied with customer's demand for the lack of business process management, management organization, information feedback, and readiness for defect in construction phase. To solve this problem, this study proposed business process management improvement model for defect management. Proposed improvement model make information feedback, defect management business quality improvement, and improper process improvement through integrating defect management and quality management. It is expected to contribute to customer's satisfaction improvement and reliance improvement for construction companies.

One role of waterproofing work is to block external moisture and water. Defects in waterproofing work in building construction brings on huge repair costs for related construction work as well as for the waterproofing layer itself. However, we don't have a quantitative probabilistic management method for waterproofing work to successfully anticipate and prevent defects. From an analysis of the literature and prior research, defects in the waterproofing work in the underground parts of buildings occur frequently. We selected Fluid-Applied Membrane waterproofing work as representing waterproofing work in the underground parts of a building, and researched the general types and causes of defects. In this study, we developed the Relative-FMEA (Failure Mode and Effect Analysis) approach that merges the Matrix method and FMEA. From a survey of experts, we deduced the most important management factors for Fluid-Applied Membrane waterproofing work for the underground parts of buildings.
