최근 국토교통부 '제6차 건설기술진흥기본계획' 및 '스마트 건설 활성화 방안(2022.7.20.)' 등에서 국내 건설 산업 혁신 방안의 하나로 제시되고 있는 PC (Precast Concrete), 모듈러(Modular) 등 탈 현장 건설 생산방식인 OSC (Off-Site Construction)는 공기 단축, 원가 절감, 품질 향상, 건설 폐기물 감소, 안전사고 감소 등 각종 장점이 있는 것으로 알려져 있으나, 현장타설 기반의 전통적 RC공법에 비해 비싼 공사비로 인하여 활용 확산에 제약이 되어왔다. 본 연구에서는 이러한 OSC 활용성을 개선할 수 있도록 공동주택을 대상으로 계획·설계단계에서의 의사결정을 지원할 수 있는 경제성 분석 지표 및 방법론을 제안하였다. 국내·외 연구, 기술자료 조사 등을 통해 전통적인 경제성 분석의 틀에서 공사비 외에도 정량화 가능한 다양한 공동주택 OSC(PC공법 기반) 방식의 경제성 연관 요인들의 특성을 검토하였으며, 최종 편익 부문 지표로는 OSC의 기술적 장점을 반영한 '공사기간', '재해발생', '폐기물발생', '온실가스배출' 을 도출하였다. 또한, 이렇게 제시된 경제성 분석 지표 및 편익 산출기준을 실제 공동주택 사례 데이터를 기반으로 시나리오 분석을 실시하여, 기존 RC공법과의 공사비 차이를 상쇄시키는 편익 수준을 검토하였다. 향후 세부 지표별 측정 기준 적용성에 대해 추가적인 사례 연구 수행과 편익 지표 보완이 필요할 것으로 판단되며, 이를 통해 보다 개선된 효과 검증도 가능할 것으로 판단된다.

Abstract ▼ AI-Helper

Recently, the Ministry of Land, Infrastructure and Transport presented the '6th Construction Technology Promotion Basic Plan' and 'Smart Construction Revitalization Plan (2022.7.20)'. Off-Site Construction (OSC), which involves construction and production of PC (Precast Concrete) and Modular, etc., has advantages in shortening the construction period, reducing costs, improving quality, reducing construction waste, and reducing safety accidents. However, the construction cost is high compared to the traditional RC construction method, which has hindered its utilization and spread. In this study, OSC utilization was improved. An economic analysis indicator and methodology that can support decision-making in the planning and design stages for multi-unit housing were proposed. The factors used in the economic analysis of OSC (based on the PC method) of apartment houses were reviewed. As for the indicators used in the cost and benefit section, 'Construction Period', 'Disaster Occurrence', 'Waste Generation', and 'Greenhouse gas Emission', which reflect the technical advantages of OSC, were derived. In addition, a scenario analysis was conducted based on actual apartment housing case data for the presented economic analysis indicators and benefit calculation standards. The level of benefit that offsets the difference between the existing RC construction method and the construction cost was reviewed. In future studies, it will be necessary to conduct additional case studies to apply the measurement criteria for detailed indicators and supplement the benefit indicators.
