To get correct and accurate measurement for this we use SMM2 ( Standard method of measurement) provides basis for measuring building works and embodies the essentials of good practice.
In general defined as a process or the result of determining the scale of a quantity, such as length or mass, relative to a unit of measurement, such as a meter or a kilogram

Principle of Measurement
Column 1 – Timesing Column
Multiplying figures are entered when there is more than one
Column 2 – Dimension Column
Actual dimensions as scaled or taken direct from the drawings, are entered.
There may be one, two or three lines of dimensions in an item depending on whether it is linear, square or cubic.

Column 3 – Squaring Column
Length, area or volume obtained by multiplying together the figures in column 1 and 2 is recorded, ready for transfer to the abstract or bill.
Column 4 – Description Column
Written description of each item is entered.
The right hand side of this wider column is frequently used to accommodate preliminary calculations.
