WebHooks: The engineer needs to make sure standard hooks at the ends of the reinforcing bars will fit within the slab depth, while providing adequate concrete cover. If the hooks do not fit within the slab depth, then the following options should be considered: • Use smaller-diameter bars (smaller bars results in smaller hooks);
