초록

최근 공동주택에서의 OSC (Off-Site Construction)기반 PC구조의 객관적인 원가기준 마련을 위해 공장제작-현장설치 단계의 공사비 산정을 위한 품셈 체계를 제안하였다(Lee et al., 2021). 또한, 건설공사 표준품셈에서도 보편적인 PC공사의 현장설치 단계에 적용할 수 있는 주요 부재의 표준품셈을 제시하는 등 PC공사의 공사비를 체계적으로 산출할 수 있는 제도적 기반이 마련되는 추세이다. 본 연구에서는 공동주택 PC구조의 현장조사 결과를 분석하고 전문가 의견을 수렴하여 공동주택 PC공법에 적용할 수 있는 공장제작-현장설치 품셈을 개발하였으며, 현행 표준품셈 기준과 비교하여 공동주택의 현장 및 부재특성에 적용할 수 있도록 표준품셈의 보완 방향을 제시하였다. 또한, 개발 품셈을 활용하여 공사비를 산출하고 동일규모의 공동주택 RC공법과 공사비를 비교함으로써 PC공법의 비용발생 특성 및 원가절감 방안을 도출하였다. 본 연구에서 도출한 PC공법의 표준품셈은 PC공법 공사비 산출결과의 객관성과 일관성을 확보함으로서 PC공법 적용 확산에 기여할 수 있을것으로 기대된다.

A construction standard production rates system for the factory built and on-site installation phases of OSC (Off-Site Construction)-based precast concrete (PC) structures in apartment buildings was recently proposed to establish an objective cost standard (Lee et al., 2021). In addition, the Korean government has taken steps to improve the institutional foundation for the systematic calculation of PC construction costs such as revising construction standard production rates for major components that can be applied to the on-site installation phase of PC method. In this study, we analyzed the results of a field survey of apartment building PC structures and collected expert opinions to develop factory-built and on-site installation standard production rates that can be applied to apartment building PC method. We also propose directions for improving the standard production rates so that they can be applied to the site and component of apartment buildings by comparing them with the current standard production rates. This study also derived the cost characteristics and cost reduction measures of PC construction by calculating the construction costs using the developed rates and comparing the construction costs with the RC methods of apartment buildings of the same scale. The construction standard production rates for PC construction derived in this study are expected to contribute to the spread of PC construction by ensuring the objectivity and consistency of the results of PC methods cost estimation.
