Bar Bending Schedule (BBS) is an essential component in civil engineering that helps in managing reinforcement bars (rebars) used in construction. Whether you’re working on a commercial building in New York or a residential G+2 home in Pune, a properly prepared BBS ensures accuracy, cost efficiency, and ease in project execution.
If you’re a civil engineer, site supervisor, quantity surveyor, or even a student learning structural design, this post is your ultimate guide. You’ll also get a free downloadable Excel sheet to start preparing your own BBS today. So scroll till the end to Download BBS Excel Sheet Free!
🏗️ What is a Bar Bending Schedule (BBS)?
A Bar Bending Schedule (BBS) is a detailed list of reinforcement bars, specifying the type, size, location, length, bending details, and quantity for each bar required in a reinforced concrete structure.
In simpler terms, it acts as the “inventory sheet” of steel bars used for columns, beams, slabs, footings, and more.
🔹 Purpose of BBS:
- Optimized material usage
- Accurate cost estimation
- Simplified cutting & bending operations
- Smooth inspection and verification
And yes, if you’re wondering how to start building your own BBS, we got you! Simply Download BBS Excel Sheet Free using the link at the end.
📚 Why Use BBS? (India & USA Use Cases)
🇺🇸 In the USA:
BBS is widely used in commercial infrastructure, bridges, highways, and high-rise construction where precise rebar calculation is necessary. BBS ensures minimal wastage and perfect alignment with ACI and ASTM standards.
🇮🇳 In India:
BBS is essential in almost every residential and commercial project. It’s used by contractors, site engineers, diploma students, and even small-time builders to reduce steel wastage and manage labor better.
Regardless of geography, if you’re dealing with reinforced concrete structures, you’ll definitely benefit from preparing a good BBS. Don’t forget to Download BBS Excel Sheet Free to see a real-life example!
🧮 How to Prepare a Bar Bending Schedule?
Here’s how to create a BBS in just a few steps:
1. Refer the Structural Drawings
Start with reading the reinforcement drawings properly. You’ll get all the needed details like shape, bar type, diameter, spacing, and bar location.
2. Create the Following Columns:
| Field | Description |
|---|---|
| Bar Mark | Unique ID of bar |
| Bar Shape | U, L, Crank, Hook, etc. |
| Diameter | In mm/inch (TMT 8mm, 10mm, etc.) |
| Length | Length before bending |
| Cutting Length | Adjusted for hooks & bends |
| No. of Bars | Count of bars needed |
| Weight | Calculated by formula (d²/162) × Length × Qty |

📐 Cutting Length Calculation
Bending increases the length of the bar due to its ductility. Here’s how to adjust:
🔹 For 90° Bends:
Cutting Length = Total Length – (2 × Diameter × No. of Bends)
🔹 For 135° Hooks:
Cutting Length = Total Length – (3 × Diameter × No. of Bends)
🔹 For Stirrups:
- 90° Hook: (2A + 2B) + 20 × dia
- 135° Hook: (2A + 2B) + 24 × dia
Rather than calculate all this manually, it’s easier if you Download BBS Excel Sheet Free and just input values—formulas are pre-applied!
🔢 Example: Stirrups Calculation
Let’s say you need stirrups at 150 mm c/c spacing along a 6800 mm long beam.
Formula:
Number of stirrups = (Length / Spacing) + 1
= (6800 / 150) + 1
= 46.33 → Round up to 47
Simple! You can input this data in the Excel template to auto-calculate values. So don’t wait, Download BBS Excel Sheet Free now.
🛠️ Who Uses BBS?
Bar Bending Schedules are used by a variety of professionals:
- ✅ Site Engineers – To guide rebar cutting and bending
- ✅ Contractors – To estimate steel quantities and costs
- ✅ Quantity Surveyors – For precise BOQ and costing
- ✅ Steel Fabricators – For cutting and delivery
- ✅ Clerks of Works/Inspectors – For checking compliance
- ✅ Students – To learn practical site-level calculations
Every role benefits from an accurate BBS, and every one of them would love to Download BBS Excel Sheet Free to speed up their tasks.
🌍 International Standardization: BS 8666 & IS Codes
In the UK and internationally, BBS preparation follows BS 8666:2005.
In India, it follows IS 2502 and IS 456:2000 guidelines.
Most templates, including the one we’re offering, are compliant with these. So whether you work under IS Codes or BS standards, feel free to Download BBS Excel Sheet Free and start using it.
