Abstract

The main purpose of this study is to identify the tasks performed at the construction stage of apartment houses and analyze the major construction tasks that may affect the performance indicators and analyze the impact on project performance. Based on expert opinions through preliminary research, pilot data, construction database, and other research trends, domestic and foreign research trends are divided into five major tasks, and each is divided into process management (P'1 ~ P'6), construction management (C'1 ~ C'5), environmental management (E'1 ~ E'4), quality control (Q'1 ~ Q'5), safety management (S'1 ~ S'5). Subsequently, each major task was subdivided into 24 detailed tasks. An independent t-test was conducted to analyze the impact on cost. We compared the importance of achieving the project goal and identified the construction work of concrete important construction which affects not only the cost but also the schedule performance index for the degree of significance of less than 0.05.

본 연구의 주목적은 공동주택 설비 시공 단계에서 수행되는 업무들을 파악하고 성과지표에 영향을 줄 수 있는 주요 시공업무를 분석하여 프로젝트의 성과에 미치는 영향을 분석하는데 있다. 국내 외 연구동향을 비롯한 선행연구와 예비 데이터 수집(pilot data), 시공업무 데이터베이스 구축을 통한 전문가 의견을 바탕으로 시공업무를 크게 5개의 주요업무로 구분하고 각각을 공정관리(P'1~P'6), 시공관리(C'1~C'5), 환경관리(E'1~E'4), 품질관리(Q'1~Q'5), 안전관리(S'1~S'5)으로 명명하였다. 그 후, 각각의 주요 업무를 세분화 시켜 총 24개의 세부 시공업무로 분류하였다. 원가 및 공기에 대한 영향을 분석하기 위해 independent t-test를 실시하였다. 프로젝트 목표 달성에 따른 중요도를 비교하여 유의도 0.05 이하에 대해 원가뿐만 아니라 공기의 성과지표에 공통적으로 영향을 미치는 구체적인 중요 공사의 시공업무를 파악하였다.
