Question

how to estimate the cost of the tank ?

Answer 1

to estimate cost of tank

we should consider cost of material used & fabrication cost to manufacture it

material cost consist

cost of material used to construct shell, top &bottom

this is calculated in terms cost of plates

no. of plates required to construct tank is calculated

A.    total material cost = no. of plates used * cost per plate or sheet of material
B.Fabrication & erection cost

fabrication cost = no. of manpower * working hours per day*no. of days * cost per hour

C. if any rubber lining is used consier its cost

D. take profit margin 10% (assumed)

E. tansporation cost is 2%

tank cost = 1.12(A+B+C)

1.12 factor is came as we consider transportation & profit margin total 12% extra so total cost will be 112% that is 1.12 of product cost

tank cost = 1.12(material cost+labour cost+rubber lining cost)
