This process of listing the location, type and size, number of and all other details is called Scheduling.In context of Reinforcement bars, it is called bar scheduling.In short, Bar Bending Schedule is a way of organizing rebars for each structural unit, giving detailed reinforcement requirements.The form of bar and fabric schedule and the shapes of bar used should be in accordance with BS 8666.
It is preferable that bars should be listed in the schedule in numerical order. It is essential that the bar mark reference on the label attached to a bundle of bars refers uniquely to a particular group or set of bars of defined length, size, shape and type used on the job. This is imperative as a bar mark reference can then point to a class of bar characteristics. Also, this helps steel fixers and laborers keep track of the type and number of bars needed to complete a certain work. Bar Bending Schedule is used by the: Detailer person checking the drawing contractor who orders the reinforcement organization responsible for fabricating the reinforcement steel fixer clerk of works or other inspector the quantity surveyor Quantity surveyor is responsible for estimation and costing operations of a project. Engineers Reading Civil Engineering Drawings This leads to an estimation of the quantity of steel, which translates to the cost requirements for steel work. Hence, BBS is used by the contractor who orders the reinforcements as well. Clerk of works and other inspectors refer to the BBS to make sure that the reinforcement work in the site is in tandem with the design requirements as per drawings. It is used as a frame of reference by the steel fixers firsthand. In essence, Bar Bending Schedule subsumes all necessary information on reinforcements, used by professionals at various stages of the construction process, right from procurement to finish. How to prepare a BBS Necessary Columns Bar numberBar Mark Reference Bar shape Diameter Spacing Length of bar Cutting Length Number of bars Most of the information in a BBS can be found in reinforcement drawings of the structural unit. Bar shape, diameter, length and spacing is directly entered in the schedule just by looking at the drawings, which will have detailed dimensioning. Beam reinforcement bar marking for BBS Number of bars: Suppose the spacing of stirrups is 150 cc and the length along which they are placed is 6800 mm, we can find the number of bars by the formula below Length Spacing 1 number of bars 6800 150 1 46.33 In this case, we always round up. Hence, the length of a bar is increased when bends or hooks are introduced. Hence, certain deductions are needed to offset this increase in length. Cutting Length True Length of a bar Deductions For 45 degree Cutting length Total length 1 x Dia of bar x No. Bar Bending Schedule Spreadsheet How To Bar BendingCategories Civil Engineering Articles, Civil Engineering Articles for Mobile, QA QC Tags Bar Bending Schedules, BBS, BBS example, BBS requirements, how to Bar Bending Schedule, how to prepare BBS, Sample sheet Post navigation Numerical Analysis and Computational Mechanics Project Topics 1 5 Reasons Why Prestressed Concrete is Required Advantages of PSC Related Topics Interesting Facts about New River Gorge Bridge, the Gorgeous Various Strands of Mix Designing, Significance Specific Principles Reinforced Concrete Beam Concepts Interview Questions Shear Connector in Composite Construction Types Design Requirements Testing GROUND TREATMENT WITH LIME COLUMNS CEMENT COLUMNS Recent Posts 6 Things to do when you win the lottery Home Construction Quotes: Where to Get Them Irrigation Engineering Quiz Part A Interview Questions Steel Construction Part C Quiz and Interview Questions Geotechnical Engineering Quiz Part 1 Contents 1 What is meant by Bar Bending Schedule (BBS) 1.1 General guidelines to be followed in preparing BBS: 1.2 Bar Bending Schedule is used by the: 1.3 How to prepare a BBS 1.3.1 Necessary Columns 2 Example BBS Calculation 2020 CivilDigital Built with GeneratePress.
