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.

Explanation:
To understand the deduction at the L-junction of the wall for the total length of the central line, let's break down the options and analyze them.

a) Half the thickness of the wall:
If the deduction at the L-junction was half the thickness of the wall, it would mean that the central line would be shorter by half the thickness of the wall at the junction. This option is incorrect because it assumes that there is a reduction in length.

b) No reduction:
This is the correct option. When an L-junction is formed in a wall, there is no deduction or reduction in the length of the central line. The central line continues straight through the junction without any alteration in length.

c) Thickness of wall:
If the deduction at the L-junction was the thickness of the wall, it would mean that the central line would be shorter by the full thickness of the wall at the junction. This option is incorrect because it assumes that the entire thickness of the wall is deducted.

d) Twice the thickness of the wall:
If the deduction at the L-junction was twice the thickness of the wall, it would mean that the central line would be shorter by double the thickness of the wall at the junction. This option is incorrect because it assumes an excessive deduction.

Conclusion:
Therefore, the deduction at the L-junction of the wall for the total length of the central line is no reduction. The central line continues straight through the junction without any alteration in length.
