Note to Reader • This presentation was prepared for the purposes of answering e-mail questions from the prior year. This years version may look substantially different.
Question 1 • “What exactly is a ‘factored equipment estimate’ ?“ • What’s a “base cost”, “bare module cost” and what’s included in the latter? • What factors are applied to get a total estimate of the plant? • What do these factors take into account?
Equipment Purchase Price Equipment Factor “Off Sites” Cost Direct Field Labour (DFL) Direct Field Cost (DFC) 0.25 x DFC 0.25 x DFC Indirect Field Cost (IFC) 1.0 to 1.6 x DFL Home Office Engineering Allowances Total Project Cost (ITC) From Equipment Price to DFC Estimate • DIRECT FIELD COSTS • Equipment Cost • bulk materials & labour to install • off-sites (pipe racks, rail spurs …) • INDIRECT FIELD COSTS • engineering, freight, insurance, overhead • CONTINGENCY AND FEES • first fill of plant, taxes, duties • escalation • Tanks and Vessels • Columns and Trays • Pumps and Compressors • Exchangers • Heaters TOTAL PROJECT COST x Factors • Plus Off Sites, ie Piperacks,Rail Spurs, Tank Farms etc Direct Field Cost
Estimate • DIRECT FIELD COSTS • Equipment Cost • bulk materials (piping, valves, instruments) & labour to install • off-sites (pipe racks, rail spurs …) • INDIRECT FIELD COSTS • engineering, freight, insurance, overhead, const supervision • CONTINGENCY AND FEES • first fill of plant, taxes, duties • escalation TOTAL PROJECT (CAPITAL) COST
Method 1: Lang Factored Estimate Total Capital Cost = Flang * (Sum Of Purchased Cost of Equipment) Flang = 4.74 for fluid processing plant

Method 3: The CAPCOST Approach Equipment Parameters (Pressure, MOC, Size, Hp …) “Base Cost” = Purchase Cost of Equipment - in Carbon Steel and 0 barg Which One Do We Want? Bare Module Factor = f (Factorpressure, Factormaterial) BARE MODULE COST (Directs and Indirects) - installed equipment in actual materials and actual pressure Module Factor = 1.18 MODULE COST OF PLANT - for expansion to an existing Plant -contingency 15%, fees 3% CHEE 470 Stops Here Grass Roots Factor = 1.30 GRASS ROOTS COST OF PLANT - infrastruction (utilities, off-sites aux. Buildings, product storage, loading and unloading facilities ...)
Determine Equipment Cost Note: Price for Carbon Steel Construction and 0 Bar(g) Fixed Tube exch with 28 m2 = $6500 Convert To Today’s $’s using the CEPCI value
Factor to Today’s Cost $6500 * (1999 CECPI / 1996 CECPI) = today’s cost $6500 x (390.6 / 381.7) = $6650 in 1999
Pressure Factor (Fp) Pressure Factor Fp = 1.14
Bare Module Factor FBM Fp Fm 1.14 x 3 = 3.42 Therefore FBM = 7 Bare Module Cost = Base Cost x FBM = $6650 x 7 = $46,550 Nowhere is the purchased cost of the equipment (at design press and materials)
Module Cost Of Plant Add Contingency and Fees (building permits, environmental permits etc.) Module Cost = 1.18 S (of Bare Module Cost for all equipment) Module Cost = 1.18 x $46,550 = $ 54,900
Question 2 • What is a capital cost?
Capital Cost • What’s “Capital ?” • Capital is the money required to build a plant or facility • It’s separated from “Expense” money because of the Tax implications imposed by Revenue Canada, IRS, etc.
Facility Timeline Facility Creation Facility Operation Conceptual Engineering Detailed Engineering & Construction Start-up Capital $ Expense $ Expense $ Expense $ - Operating Expenses -Depreciation Capital Cost
Capital vs Expense • Once the plant is running ‘Expenses’ are small items or costs which are incurred yearly, or have about a 1 year life. • i.e. Software, Office supplies, wages, advertising, heat, lighting, ... • When Calculating Yearly Income Subtract your Expenses From Your Income
Capital vs Expense • ‘Capital’ are expensive items or items which have more than a year of life. • i.e. House, lawnmower, TV, computer, chemical plant equip, first fill of chemicals • Revenue Canada etc. only allow you to subtract a % of the Capital every year to account for the wearing out of the facility (depreciation). • This is called the “Capital Cost Allowance”
Capital vs Expense • Capital Cost Allowance ( CCA ) • Works Like a Bank Account • Revenue Canada allow a % of the remaining asset value to be claimed Remaining Asset Value Time (years)
Taxable Income • Income That’s Taxable (Net Income) Taxable Income = Income - Expenses - CCA Can’t use CCA if Expenses are greater than Income (can’t use CCA to claim a loss) CCA can be ‘banked’ for later years where profit is occurring
Capital - The Point • Capital is only allowed to be ‘depreciated’ over years and thus it’s ability to minimize taxable income is limited. • Expenses are claimed in the year they’re paid. They’re better for minimizing your taxes. • The Games People play
The Capital Cost Estimate • The tax implications of Capital money requires that you know how much Capital was spent on any asset. • The business financial analysis (NPV etc.) requires that you know the Capital Cost and the Operating Cost well ahead of actually spending any significant amounts of money.
Capital Cost Estimate • Summary: The cost to initially build the facility which will be depreciated over time.
Question 3 -CAPCOST - arrggh! • “When our tube/shell design pressures are below those which CAPCOST recognizes, do we simply take the minimum CAPCOST pressure and size on that basis?”
Off The Shelf Items • Piping, Valves, Pumps and most equipment have been standarized in design pressures of the connecting Flange • Standards are called 150, 300, 600, 900, 1500, 2500 “lb” flange ratings. • A 150lb rating 150 psig rating, temperature is important in the ultimate strength of the item • Along with standard flanges are standard pipe wall thickness (Sch 40, Sch 80 etc.) ASME Code
Heat Exchanger Standards • TEMA - Tubular Exchanger Manufacturers Association • dictates minimum requirements for exchanger mechanical design • Legislation does not require TEMA standards be used.
ASME- Pressure Vessel Standards • ASME Code • It started in Chicago after a major explosion in a shoe factory that had a boiler. The boiler explosion caused the government to start regulating pressure vessels (including boilers). • A tool for regulating manufacturers of pressure vessels, heating exchangers, and piping, not pumps, not compressors (no rotating equipment)
ASME- Pressure Vessel Standards • Since the explosion in Chicago codes were developed for the guidance in the calculation of pressure vessels, tables of metal strength vs temp • Safety factor of 4 has historically been applied to the mechanical strength of metal, recently (this year) it was reduced to 3.5
ASME Code Sections I - Power Boilers II - Materials (properties i.e. allowable stresses) III - Nuclear Power Plants IV - Heating Boilers V - Non Destructive Examination VII - Guidelines for the Care and Operation of Heating Boilers IX - Welding and Brazing Qualifications X - Fiber-Reinforced Plastic Pressure Vessels XI - Rules for Inservice Inspection of Nuclear Power Plant Components
Minimum Design and CAPCOST • Allowing CAPCOST to choose a minimum makes sense since the manufacturer would do the same.
Question 4 - Unknown Equipment • To size the reactor cooling jacket do we send you our data? Is there significant expense in the jacket? • Jacket cost is about $35,000 for the reactor.
CAPCOST - User Added Eq. • Treat as an additional piece of equipment • Bare Module factor is irrelevant
Question 5 - Storage Tanks • How do you do the costing for the cone roof storage tanks?
User Added - Storage Tanks $239,000 Multiply by 2 to get “bare module cost”
Question 5 -Agitator • “How can we account for the agitator (shaft, seal + motor) cost in our estimate?”
Agitator Costs $65,000 Multiply by 3.0 to get “bare module cost” in CAPCOST
