Is there any method to arrive at total manpower reqiered to finish a project with a break down for mason steel fixer and carpenters
I try to solve an example shown below, please correct me if I am wrong????
3 basement + ground + mezzanine floor + 20 typical floor + roof
Basement has 2000 m2 area and each typical floor has 1000 m2
1: calculate total man power required?
Total Area =3x2000+2000+2000+20x1000+1000= 31,000 m2
Total manpower required for completion of project with I shift working daily = 31,000 X 8 = 248,000 man days
( please correct me and Show the thumb rule)
2: peak of the project ?
Average =248,000/24/30 = 344 nos
Peak = 1.95 X 344 = 670 nos at peak
3: each trade percentage of contribution say (Steel fixer+ helper) 32% of peak, (carpenters + helpers) 30 % of peak and reaming (masons + helper ) 38 %
Steel fixer + helpers = 32 %X 670 = 214 nos
carpenters + helpers = 30 %X 670 = 210 nos
masons + helper ) = 38 % X 670 = 254 numbers
All together if you know the thumb rule to calculate please guide, without going into details of each activities which could be 5000…!!!
Do tell me what is the restrains of labour working in an area? I what is the maximum no that can work in an area.??
