초록

국내 공공임대주택에서 유지관리 단계에서의 수선유지비는 효율적 관리의 필요와 함께 그 중요성이 부각되고 있다. 본 연구에서는 수선유지비를 예측하는 방법으로서 기존의 실적자료를 통한 방법을 대신하여 물량기반의 예측방법을 제안하고자 한다. 견적방식 모델을 통하여 공동주택 유지관리단계의 40년간을 대상으로 연차 단위별로 수선유지비용을 예측하고 분포 특성에 대한 정보를 제공한다. 수선유지비예측의 정확성을 제고하기 위해, 최근 변경된 장기수선항목 및 수선주기를 반영하였다. 또한 최근에 건설된 공동주택 마감수준을 수선대상으로 포함하였다. 수량산출은 공공임대주택 5개 사례현장을 선정하여 수행되었으며, 세대수 및 연면적 단위로 환산하여 공공임대주택의 수선유지비를 범용적으로 예측하는데 활용될 수 있도록 분석하였다.

The repair and maintenance cost of domestic public rental housing is an issue of considerable interest and growing financial concern. This paper suggests a quantity-based model as an alternative method for predicting costs, instead of the conventional model which is based on actual cost data. Furthermore, this paper provides a forecast of the repair costs incurred each year during the multi family house's maintenance phase (40 years). The recently changed the long-term repair plan and quality-improved interior materials were considered into the research. In order to estimate the cost of maintenance work, 5 sample apartments were selected and analyzed. The repair and maintenance cost from the case studies was converted to cost per household and per floor area for general use. On the other hand, the net present value method was applied to reflect the effect of time. We expect that the results will help to establish expenditure plans that are more effective for public rental housing in the maintenance stage.
