Abstract

The Construction Standard Unit Price (CSUP) sets the standard for calculating the estimated construction cost. The CSUP is used as basic data for preparing a standard price for public construction. Currently, the CSUP is calculated in consideration of the market and construction field conditions. However, a long-term management plan was established to prepare revised standards. As part of the plan, a field survey was conducted on changes in construction conditions and market prices. However, the plan continued for more than 5 years. Thus, the plan has a problem of difficulty continuously managing primary activities that have high importance and high price volatility. Therefore, to efficiently manage the CSUP, this study identifies the primary activities of the CSUP and presents a management plan. Through importance analysis and unit price volatility analysis, 242 primary activities in 35 activity groups were identified. Also, a management plan is presented based on the importance levels of activities. The primary activities and management plan could enable the timely revision of important activities. The results of this study provide a base for reflecting the appropriateness of construction cost criteria on time.

건설공사의 적정한 공사비산정을 위하여 건설공사의 실적을 토대로 하는 표준시장단가가 작성되고 있으며, 공공건설공사의 예정가격 작성을 위한 기초자료로 활용되고 있다. 현재 표준시장단가는 건설현장 시장상황 및 시공상황을 고려하여 산출되고, 보정기준을 마련하기 위하여 중장기 정비계획을 수립하여 공종별 시공실태 및 시장가격 변화에 대한 현장조사를 수행하고 있다. 그러나 중장기계획 정비가 5년 이상으로 장기화되고, 일시적 정비로는 중요도가 높고 단가변동성이 큰 핵심공종들에 대한 지속적인 관리가 어려운 문제점이 발생되고 있다. 이에 본 연구는 표준시장단가 적기 개정을 통한 적정공사비 확보를 위하여 표준시장단가 핵심공종을 도출하고, 중점관리방안을 제시하였다. 중요도 및 단가변동성 분석을 통하여 35개 조사그룹에 해당하는 242개 핵심공종들을 도출하였으며, 공종들의 중요 수준을 고려하여 중점관리방안을 제시하였다. 제시된 핵심공종 및 중점관리방안을 통하여 중요 공종들의 적기 개정이 가능할 것으로 판단된다. 또한 향후 중장기계획 재수립시 핵심공종에 대한 지속적인 관리방안을 수립하여, 공사비산정기준의 적절성을 적시적재에 반영할 수 있도록 기반을 마련하였다.
