A Bar Bending Schedule (BBS) is a document that provides detailed information about the reinforcement steel bars used in a construction project. It is primarily created for the benefit of clients, engineers, and contractors involved in the construction process. The BBS includes the following information:
- Bar Marking: Each reinforcement bar is assigned a unique identification number or mark, which is mentioned in the BBS. This mark helps in identifying and locating the bars accurately during construction.
- Bar Shape and Dimensions: The BBS provides information about the shape and dimensions of each reinforcement bar. It specifies the diameter, length, and any additional bends or shapes that need to be incorporated into the bar.
- Bar Quantity: The BBS specifies the quantity of each reinforcement bar required for the project. It provides a detailed breakdown of the number of bars needed for each size, shape, and location within the structure.
- Bar Cutting Lengths: The BBS provides the cutting lengths for each bar. It specifies the length at which the bar needs to be cut from the stock length, accounting for the overlapping and development lengths required for proper reinforcement.
