Abstract

This study has conducted case studies in order to suggest alternatives to the historical data-based estimate system. Price fluctuation calculation methods based on historial cost indexes, standard estimate and construction cost indexes were applied to 9 road construction sites in Jeju for an analysis. As a result, in 5 construction sites (about 56% of 9 sites), the index control rate calculated based upon historical data-based estimate system was higher than that calculated based upon standard estimate and construction cost indexes. Thus the establishment of the requirements for the adjustment of contract price due to price fluctuation delays, which leads to a significant difference in price fluctuation amount. And, in an analysis of construction cost indexes, the indexes for road construction were used for calculating index control rate which ranges from 2.0 to 9.4 percent, indicating the time of construction amount and price fluctuation application has a significant influence on index control rate.

본 연구는 제주특별자치도 내 실적공사비가 적용된 도로현장을 중심으로 물가변동에 따른 실적공사비 등락률 산정의 문제점을 분석하기 위하여 실시되었다. 본 연구를 위하여 제주특별자치도 내 9개 도로공사 현장을 중심으로 실적공사비방식, 표준품셈방식, 건설공사비지수방식에 따른 등락률을 비교 분석하였다. 분석결과 9개 현장 중 약 56%인 5개 현장에서 실적공사비의 지수조정률이 표준품셈과 건설공사비지수의 지수조정률에 비해 낮게 산정되었다. 이는 실적공사비가 적용됨에 따라 물가변동으로 인한 계약금액 조정 성립요건이 지연되고 있다는 것을 알 수 있으며, 이에 따라 공사 준공 전 물가변동으로 인한 계약금액 조정횟수의 감소와 함께 물가변동금액 역시 차이를 보일 수 있음을 의미한다. 또한, 건설공사비지수 사례분석 결과, 도로부문에 대한 지수를 적용하여 지수조정률을 산출하였으나 지수조정률이 2.0%~9.4%까지 산정되어 이는 공사금액 및 물가변동 적용시기에 따라 상당한 영향을 미치는 문제점이 나타났다.
