Abstract

Prefabrication and just-in-time delivery are important in lean supply system. Past research focuses on how much lead time is reduced and how much costs are saved, but few have studied on the environmental impacts. While most studies on the environmental impacts have focused on select life-cycle phases or specific building materials and components, the impacts of different construction methods or supply strategies from the construction phase are ignored or simply approximated. This paper presents results of a case study where the environmental impacts of prefabrication and just-in-time delivery strategy of rebar supply on a high-rise condominium project in Seal, Korea.
