Dear Readers,
ABW means
Average Basic Wages. ABW is playing vital role in costing and rate analysis of
construction works.
To find an ABW
we must know the Gang Composition. Gang means to execute the particular
activity we need a workforce which comprise a set of manpower with different
categories based on their skills.
Obviously, unit
rate will not be same for each workman in the gang, since they are having
different skills.
ABW is equal to
Average Product of workmen and their wages.
ABW = {[Sum of
(Manpower X Wages)] / No. Manpower}
Gang Composition
is playing one of the important vital roles for rate analysis to get an optimum
ABW. Gang Composition is directly related to productivity. A well-organized
work, less labour is required.
ABW shall be
calculated in two methods. One is if you know the gang composition and another
one is without gang composition.
Following type
can be used when we are identified a gang
Following type
can be used when we could not identify a gang
Both Table shows different ABW for the same example. This is due to difference between Actual and Approximate. First table , we identified the gang composition. Second table is based on the approximate.
