What is a Bar Bending Schedule? Reinforcing Steel Contractors
Bar Bending Shape Codes by Ronald Shape codes are the building stones of a perfect bar bending schedule. When calculating the reinforcement detailing for different members for a building, taking account of small bent ups and other angle detailing will make the difference of effective and economic BBS.

BS 4466: 1989 Shape Codes In April 2000 a new British Standard, BS8666 the 'Specification for scheduling, dimensioning, bending and cutting of steel reinforcement for concrete' was introduced, replacing BS 4466. Although BS4466 is superseded it is still used and is described below for reference purposes. BS 4466 - Non Preferred Shapes Notes

BS8666 is the British Standard rebar shape code list required to be adhered to when using steel to reinforce concrete in construction in the United Kingdom and Northern Ireland. The latest update, BS8666:2020 (from BS8666:2005) updates the standard more closely inline with BS EN 1992-1-1 Eurocode 2 (which you can download for free here ).

Bar Markings There are a number of ways to identify reinforcing bar (rebar) from the production mill to the fabrication shop to the jobsite. This documentation and marking system helps provide a wealth of useful information about the manufacturing and composition of each bar of reinforcing steel.

6. The label of bar mark reference attached to the bundle bar must relate uniquely to an appropriate set or group of bars of defined shape, size, length, and type used in the work. Information on the bar schedule sheet. Member: The location in which the bar is used. Bar mark: the number of the bar in its sequence in the detail drawing.

However, a typical BBS schedule section contains 10 columns in the following order: [1] MEMBER: This shows the particular member in consideration.E.g base type 1, base type 2, column type 1, column type 2 etc [2] BAR MARK: This depicts different bar marks present in the drawing.E.g. 01, 02, 03 etc. [3] TYPE and SIZE: Type relates to whether the specified reinforcement is of high or mild yield.

A bar bending schedule, or BBS as it is sometimes referred, is a comprehensive document that describes the type, size, mark, location, length, number and bending details for all rebar required for a build. In other words, it allows for proper management of materials, limits off-cut waste, and ensures that it will be placed correctly.
