Answer:
Hours = 8000
Days = 46.78
Explanation:
The duration of this construction activity can be calculated as follows
DATA
No. of suits = 1000
Outlets to be installed = 12/suit
Standard productivity for outlet = 30mins
Fixtures to be installed = 6/suit
Standard productivity light fixture = 20mins
Working hours per day = 10 hours - 0.5 lunch break
Working hours per day = 9.5 hours
No. of crews = 18
Solution
Total time to fix = No.of suits x no. of installations x Standard time
Total time to fix = (1000 x 12 x 30mins ) + ( 1000 x 6 x 20mins)
Total time to fix = 480000 mins
Total time to fix = 480000/60mins = 8000 hours
Duration in days = Total time / (hrs per day x mo. of crews)
Duration in days = 8000 hours / (9.5 x 18)
Duration in days = 8000/171
Duration in days = 46.78 days
