In the Centre-line method at the L-joint area will be calculated twice when take-off quantity. So, this area should be deducted once from the measurement when take-off quantity. But there is no reduction in at the L-junction of a wall for the total length of the central line in this method.

Understanding L-Junctions in Walls
When assessing the central line at an L-junction of a wall, it is crucial to understand how the junction affects measurements.
What is an L-Junction?
- An L-junction refers to the point where two walls meet at a right angle, forming an "L" shape.
Central Line Measurement
- The central line represents the midpoint along the length of a wall.
- In the context of structural engineering, precise measurements are essential for stability and design.
Deduction at the L-Junction
- At the L-junction, the total length of the central line does not require any reduction.
- This is because the wall's thickness remains consistent across this junction.
Why is the Correct Answer 'No Reduction'?
- The junction does not alter the central line's positioning; therefore, the entire length is accounted for.
- Each wall's thickness remains uniform, which means it does not impact the overall measurement of the central line.
Conclusion
- Thus, the deduction at the L-junction for the total length of the central line is accurately stated as no reduction.
- This principle is vital for ensuring the integrity and accuracy of construction measurements in railway and building projects.
