Concrete floor systems are reinforced slab structures designed to satisfy a range of loading and span conditions in a building. Designed to span in either one direction (one-way) or both directions (two-way) of a structural bay, the range of concrete floor systems available are created to economically and efficiently account for the numerous and specific demands of each building project. During the design process, especially the initial planning stages of a project, the inherent expenses of concrete (30% cost), reinforcement (15% cost), and formwork (55% cost) should be considered and evaluated when choosing the appropriate concrete floor system for the building.
