Question

In partly centre line and partly cross wall method, the centre line method is applied to _______

(a) External walls

(b) Internal walls

(c) Thick walls

(d) Thin walls

I got this question during an online interview.

My query is from Estimation and Costing in portion Rate Analysis, Estimation and Costing of Construction & Building Materials

Answer 1

The correct option is (a) External walls

To elaborate: Partly centre line and partly cross wall method is adopted when the external wall has one thickness and the internal walls have different thicknesses. In such a method, the centre line method is applied to the external walls and the long wall-short wall method is applied to the internal walls.
