5) COST CALCULATION
Generally, capital cost estimating has five classifications:
1. Order of magnitude Estimate also known as Ratio or Feasiility
!. "tudy Estimate, also known as #a$or e%uipment or Factored
&. 'reliminary (esign Estimate, also known as "cope
). (efinitive Estimate, also known as 'ro$ect *ontrol
+. (etailed Estimate, also known as Firm or *ontractors
-his five classifications roughly correspond to the five classes of estimate defined in
the *E Recommended 'ractice /o. 10R203)4. -his part will discuss on
'reliminary (esign Estimate which is *lass &. For the cost estimation of a chemical
plant, a *lass & estimate is typically 5167 to )67 accurate. -his means y doing
such an estimate, the true cost of uilding the plant would likely e in the range of
6.1 higher than and 6.) lower than the estimated price. 8f greater accuracy is
re%uired in the capital cost estimate, then more money and time must e e9pended
in conducting the estimate.
A. Estimation Of Purchased Equipment Costs
-he purchased cost and an attriute of the e%uipment are the most common simple
relationship related to units of capacity and it is given y

. Effect of Time on Purchased Equipment Cost
-he cost of e%uipment is depend on past records or pulished correlations for price
information, it is essential to e ale to update these costs to take into account
changing economic conditions <inflation=. -his can e achieved y using the

-he cost of manufacturing, *O#, can e determined when the following costs areknown or can e estimated:
a= Fi9ed capital investment <F*8= : <*-# or *GR=
= *ost of operating laor <*OJ=
c= *ost of utilities <*M-=
d= *ost of waste treatment <*-=
e= *ost of raw materials <*R#=
-he tale aove gives data that are needed to calculate to estimate the individual
cost items that are identified aove. ith the e9ception of the cost of raw materials,
waste treatment, utilities, and operating laor all the data need to e calculate y
using certain e%uations. 8f no other information is availale, the midpoint values for
each of these ranges is used to estimate the costs involved. Cence, all the
summation of the datas for the calculation of manufacturing cost can e simplified
into these e%uations:
