					   CAPITAL COST
    ESTIMATES
INSTALLED EQUIPMENT COSTS
     INSTALLED COST
     ESTIMATE METHODS
   FOR TYPE 1 OR 2 FEASIBILITY ESTIMATE
   USE PURCHASED EQUIPMENT COSTS AND
    FACTORS
   SIMPLEST IS SIMPLY 4.0 FACTOR
   FOR PLANT TYPE ADJUSTMENT SEE TABLE 6-
    10. RANGES ARE FROM 4.7 -6.0.7
   USE M&S INDICES FOR INFLATION COST SCALE-
    UP
   FOR INDIVIDUAL EQUIPMENT, USE FACTORS
    FROM CHEMICAL ENGINEERING PLANT COST
    INDEX (ALSO IN CHEMICAL ENGINEERING
    MAGAZINE)
     SPECIFIC PLANTS
   THE TEXT HAS SOME PLANT DATA IN
    TABLE 6-11
   DATA IS SCALED UP FROM 1970 DATA SO
    IS IN QUESTION
   MOST ESTIMATES ARE BASED ON
    EQUIPMENT COSTS
   THAT EQUIPMENT COSTS CARRY AN
    ACCURACY LIMIT AS WELL
   - +25% IS TYPICAL FOR PEP PROJECTS
    AT SRI
        ESTIMATE EXAMPLE

         tudies/cs_04.htm
 EQUIPMENT FOR PROCESS MODIFICATION
        ESTIMATE EXAMPLE
http://www.mbendi.co.za/avec/cases
         tudies/cs_04.htm
 RELATIVE MATERIALS COSTS
    FOR TYPE 3 FUNDING
         ESTIMATE
       USE PROJECT DATA - DESIGN CRITERIA,
        DESIGN BASES, INITIAL SITE DATA
        NEED STRUCTURAL DATA
        NEED SHOP VS. FIELD FABRICATION DATA
        NEED LABOR VALUES
        USE VENDOR QUOTES FOR
        EQUIPMENT PLUS SHIPPING TO GET
        DELIVERED COSTS
FOR CONTROL BUDGET

   NEED FINAL DRAWINGS
   NEED QUOTATIONS FROM
    CONSTRUCTION SUBCONTRACTORS
    WHERE AVAILABLE
   NEED SPECIFIC COSTS FOR EQUIPMENT,
    MATERIALS, LABOR AND ERECTION
    EQUIPMENT
   NEED DEFINITION OF SHOP VS. FIELD
    RESOURCES
     CAPITAL ESTIMATE
       COMPONENTS
  DIRECT FIXED CAPITAL
     INCLUDES COMPONENTS AS PER TABLE
      6-3
  DEFINITION SUMMARY (TABLE 6-9)


TOTAL PLANT CAPITAL (TPC) = TOTAL PLANT
DIRECT CAPITAL (TPDC) + TOTAL PLANT INDIRECT
COSTS (TPIC) + WORKING CAPITAL (WC)
TPC = TPDC + TPIC+ WC
    FEASIBILITY ESTIMATE
   DEVELOP PEC AND USE PEC
    FACTORS METHOD
        TYPICAL FACTORS FOR ESTIMATE
         COMPONENTS ARE IN TABLE 6-3 & 6-17
         INSTALLATION COSTS
       DEPENDS ON AMOUNT OF PIPING VS.
        SOLIDS HANDLING (NON-SLURRY)
       INCLUDES FOUNDATION AND
        STRUCTURAL BUT NO
        INTERCONNECTING SYSTEMS
       IF ESTIMATED ON AN EQUIPMENT ITEM
        BASIS, SEE TABLE 6-5 FOR TYPICAL
        VALUES
       PROCESS PIPING FACTOR
        RANGES OVER PLANT TYPE FROM SOLIDS
         ONLY TO FLUIDS ONLY
        SEE TABLE 6-6 FOR FACTORS
         INSTRUMENTATION
              FACTORS
       RANGE FROM MANUAL TO TOTAL
        COMPUTER CONTROL, 10% - 50% OF
        PEC
        MOST PLANTS USE THE 35% LEVEL WITH
         DISTRIBUTED CONTROL SYSTEMS
        BATCH OR INTERMITTENT OPERATION
         THROUGH PROGRAMMABLE CONTROLLERS
       FOR A DISCUSSION OF THE USE OF
        WIRELESS INSTRUMENTATION :
        http://www.automationworld.com/view-1936
           OTHER FACTORS
       INSULATION FACTORS
        USED FOR CONTROL OF HEAT LOSS, HEAT
         GAIN AND PERSONNEL PROTECTION
        TOTALS RUN AROUND 8% OF PEC
       ELECTRICAL FACILITIES FACTOR
        DOES NOT INCLUDE CONTROL, BUT DOES
         INCLUDE POWER SUPPLIES.
        ASSUMES POWER FROM SOURCE OUTSIDE
         OF BATTERY LIMITS
        AMOUNTS TO ABOUT 15% OF PEC
        SEE COMPONENTS IN TABLE 6-8
             OTHER FACTORS
       BUILDINGS FACTOR
        DEPENDS ON CRITERIA
         FOR JOB
        FOR EXISTING PLANTS,
        TYPICAL VALUES ARE SHOWN IN TABLE 6-9
       YARD IMPROVEMENT
        INCLUDES ALL THE CIVIL ASPECTS OF THE
         PROJECT
            INITIAL GRADING
             UNDERGROUND UTILITY SYSTEMS
            TRANSPORTATION COMPONENTS
             AND FINISH OUTSIDE OF PROCESS AREAS
    OTHER DIRECT COSTS

   AUXILIARY SYSTEMS
       THE UTILITY COMPONENTS FROM
        OUTSIDE THE BATTERY LIMITS
        REQUIRED FOR OPERATION
       MAY INCLUDE UPGRADE OF EXISTING
        UNITS.
INDIRECT COMPONENT
      FACTORS
       ENGINEERING COSTS
        INCLUDE COSTS FOR DESIGN THROUGHOUT
         THE PROJECT. TEND TO INCLUDE ASPECTS
         OF CONSTRUCTION.
        VALUES ARE SHOWN AS TOTAL IN TABLE 6-9
       CONSTRUCTION
         INCLUDES ADMINISTRATION OF ALL
         ASPECTS OF PROJECT
        DEPENDS ON MANY FACTORS AS INDICATED
         IN TABLE 6-9
INDIRECT COMPONENT
      FACTORS
       CONTRACTORS FEE
        PROFIT AND OVERHEAD COMPONENT FOR
         ENGINEERING AND CONSTRUCTION FIRMS
        RANGES AROUND 4-6% OF TOTAL FIXED
         CAPITAL INVESTMENT
       CONTINGENCY - ANTICIPATED COSTS
        FOR CHANGES THAT WILL OCCUR
        DURING THE PROJECT
        FOR THIS PROJECT USE THE VALUES IN
         TABLE 6.17 AND EXPLAIN BASIS OF CHOICE
     METHOD D - LANG
        FACTORS
   BASED ON PEC (4.7x TO 6.0x PEC)
   BASED ON CORRELATION FOR A
    LARGE NUMBER OF PROJECTS
   OFTEN AS ACCURATE AS DETAILED
    FACTOR METHOD
   TYPICAL LANG FACTORS ARE
    SHOWN IN TABLE 6-10
