🏗️ Bar Bending Schedule (BBS) — Quick Interview Q&A
Q1. What is BBS?
BBS is a detailed list of reinforcement bars showing their diameter, shape, length, quantity, and weight.
Q2. Main components of BBS?
Bar mark
Shape/code
Diameter
Cutting length
Quantity
Total length & weight
Q3. Why is BBS important?
It helps to estimate steel accurately, reduce wastage, save cost/time, and ensure proper fabrication and placement.
Q4. What is required to prepare BBS?
Structural drawings, dimensions, concrete cover, bar details, and applicable standards.
Q5. Common shape codes?
Examples include 00 – Straight bar, 01 – One-end bent, 11 – Both-ends bent, 31 – Rectangular stirrup. Always verify with the project standard.
🔑 Key Formula:
BBS = Plan → Calculate → Cut → Bend → Place
