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

EQUIPMENT FOR PROCESS MODIFICATION

ESTIMATE EXAMPLE

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

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
