Identify the work (with codes E, F, G, H) in which the units of measurement for estimation of quantities are NOT identical.
E. Turfing of bonds of a canal
F. Wood work for door shutters
G. Centering and shuttering, formwork
H. Well sinking
Turfing of bonds of a canal is measured in m2
Wood work for door shutters is measured in m2
Centering and shuttering, formwork is measured in m2
Well sinking is measured in m
Hence in measurement well sinking is not identical to the other three.
