From the above calculation, it will take 0.2 days to fix 1 m2 of carpet. Therefore the number of
labour days needed to fix 717.17 m2 of carpet are
1 m2 → 0.2 days
717.17 m2 → 717.17 x 0. 2
1 =143. 4 34 days
The next step is to convert the labour days into tradesman hours
Assumption: there are eight working hours in one labour day
Therefore
1 labour day → 8 tradesman hours
14.3434 labour days → 14 3 . 434 x 8
1 =11 4 7 . 5tradesman hours
d) Gang size
Based on the carpet floor area and the tradesman hours calculated above, the reasonable gang
size for the carpet laying task is 2. This means that 2 tradesmen are enough to complete the job
within a reasonable number of days.
e) Completion time
The required time to complete the carpet laying task is calculated based on the recommended
gang size above.
Assumption: 0.15 tradesmen hours are required to fix 1 m2 of carpet. This means that in 1 hour,
the total area of carpet fixed is
0.15 hours = 1 m2
1 hour = 1 x .4
0.15 =6.67 m2
For the two tradesmen (gang size of 2), the total carpet fixed in 1 hour is
2 x 6.67 m2 = 13.33 m2
Therefore
