Abstract

The main purpose of this study is to analyze the impact of the cost estimates on the construction work in residential apartment housing facilities. The planning work of facility construction is roughly divided into five main tasks which are further broken down into the following: process plan (P1-P6), construction plan (C1-C5), environmental management plan (E1-E4), quality management plan (Q1-Q5) and the safety management plan (S1-S5). In this study these tasks were classified into 25 detailed planning duties and a statistical analysis was performed on each one to determine its impact on cost. Finally this study derives from major planning tasks for effective cost management through correlation between planning tasks, cost indicators and t-test.

본 연구의 주목적은 공동주택 설비 계획 단계에서 수행되는 업무들을 파악하고 성과지표에 영향을 줄 수 있는 주요 계획업무를 분석하여 프로젝트의 성과에 미치는 영향을 분석하는데 있다. 계획업무의 성과지표에 대한 영향 분석을 위하여 설비공사의 계획업무를 크게 5개의 주요업무로 구분하고 각각을 공정계획(P1~P6), 시공계획(C1~C5), 환경관리계획(E1~E4), 품질관리계획(Q1~Q5), 안전관리계획(S1~S5)으로 명명하고, 각각의 주요 업무를 세분화 시켜 총 25개의 세부 계획업무로 분류하여 원가에 대한 영향을 분석하기 위해 independent t-test를 실시하였다. 각각의 주요 업무를 세분화 시켜 총 25개의 세부 계획업무로 분류하여 원가에 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 계획업무를 파악하였다.
