This paper and a companion paper provide a review and assessment of existing precast concrete gravity load floor framing systems suitable for office buildings. The companion paper reviews 19 precast structural systems. The assessment presented in this paper treats interactions between the structural, service, and architectural systems that comprise the building system. The assessment indicates the current state-ofthe-art in precast concrete structural systems for office buildings and leads to conclusions regarding opportunities for the development of new systems and the improvement of existing systems. Work in progress is focusing on the most promising concepts evolving from this study with a view towards developing a modern, economical, and efficient precast concrete floor system.
