Abstract

As there are a lot of differences in the public building construction cost depending on the construction scale of actual construction cost system, a lot of problems occur in the estimation of the cost. So, the development of a predictive model depending on the construction scale shall be used in a way that it is applied to the case selectively and differently. This study drew a cost estimating model through a regression analysis. For this, 42 construction sites which were ordered during 2011 to 2012 by Public Procurement Service data were selected as a historical data. Based on the application of the model to new construction and the verification of its effect, the reasonable model for estimating the construction cost has been suggested.

공공건축물공사의 실적공사비제도에서 공사규모에 대한 건축공사비 차이가 크게 나타나므로, 산정방식에서 많은 문제점으로 제기된다. 이에 공사규모에 따라서 선별적, 차등적으로 적용할 예측모형의 개발이 필요하다. 이에 본 연구는 조달청에서 2011~2012년에 발주한 이미 준공된 42개 현장의 실적자료에서 공사규모 $5,000m^2{\sim}20,000m^2$으로 선정하여, 회귀분석을 통해서 추정된 모형을 도출하였다. 이를 근거로 신규공사에 적용하여 검증함으로써 합리적인 건축공사비 예측모형을 제시하였다.
