건설공사의 재시공 현황에 대한 원인분석 및 개선안에 관한 연구 : 공동주택의 공조공사를 중심으로 한 조사 및 사례연구 = A Study on the Cause Analysis and Improvements of Reconstruction on Domestic Apartment Construction

다국어 초록 (Multilingual Abstract)

This study aims to provide some efficient and effective ways to prevent reconstruction. For this study, the analysis on the current situation and various causes of reconstruction has been performed by using questionnaire survey and case studies from construction sites. The results of this study are as follows:
1.Causes of reconstruction occurrence through case studies show construction inability including technician' idleness(42.2%), misunderstanding of specification(26.7%) and imperfect specification(15.6%).
2.Influence of reconstruction on construction productivity is analysed as the following; increase of 3.8% in construction duration, increase of 5.7% in construction cost, and decrease of 4.4% in construction quality.
3.In order to prevent reconstruction, it is required to file and analyse reconstruction data, systemize construction management, train construction worders with systematic work procedural manual, and check design documents precisely.
4.Also it is necessary to develop new construction technology such as simplification, mechanization, dry-construction of work process.
