    Project FeasibilityEconometricModel

    The f ac to r s a f f ec t ing the f eas ib i l i ty and the po ten t i a lprofitability of a new project are of concern to marketers,

    developers and investors (Figure 1.1). Complex econometric

    models, which analyze these variables, have been developed

    to run on large computers . (Econometr ics i s the use of

    mathematical and statistical methods to develop and verify

    economic theo r ie s ) . Economet r i c mode l tha t can be

    developed on a PC is described here.

    In developing a PC econometric model, six factors must be

    considered.

    Capital Costs

    The capital cost of a new project can usually be determined

    with reasonable accuracy (say within 15%). Capital cost is

    an extremely important number for two reasons: first, it is

    required "up-front". The money has to be found and spent

    many years before there is a payout. Second, the overall

    profitability of a project is usually measured in terms of

    Object ives

    After reading this unit, you will be able to:

    y Understand the concept of

    l capital costs

    l working capital

    l operating costs

    y Appreciate the concept of product revenues and the interplay ofeconomic environmental factors impacting project feasibility

    y Determine techno-economic feasibility of a project

    Activity 1A

    Establish capital cost of a project

    familiar to you. Select the mostexpensive component of capitalcost and list out ways to minimizeits cost. (In case you have notdealt any project, select/formulate a project which will becalled your project in futureactivities.)

    Return on Investment (ROI). Many operating concerns and

    investors set their goals on ROI (say, a minimum of 20% per

    ann um pr e-tax). The average annu al ROI is th e tota l earnings

    d iv ided by the spec i f i ed p ro jec t l i f e t imes the to ta l

    investment. A 10% increase in capital cost wil l cause a

    corresponding 10% decrease in ROI for a project with a

    10-year life cycle. A 20% ROI on a project with a 10-year life

    means that the project will earn 20% for 10 years, which is200% on the life of the project or 100% over 5 years. This is

    equivalent to a payout period of 5 years.

    The need to mainta in a h igh ROI to att ra ct investors explains

    why there is so much pressure to keep the ini t ial capital

    investm ent to a m inimum. Fr equently, desirable options and

    expansions are deferred. Features that will improve yields

    or increase efficiency are carefully examined if they add to

    the cost.

    Activity 1B

    Establish working capital of your

    project. Determine inventorylevels of various components soas to minimize working capital.

    Work out operating costs of yourproject. List out action plans forreducing operating costs.

    cost of a new project. Major items that make up the capital

    cost ar e: (1) Land an d sit e developmen t costs , (2) Engineering,

    (commissioning) costs. The land or the site costs should be

    noted separately since they will have residual value after

    the end of the project life. For all projects there should be a

    substantial sum set aside for start-up (say 15 to 20%). This

    sum may need to be higher for new unproven projects and

    could be less for established projects. A suitable contingency

    or management reserve needs to be included in the capital

    cost estimates.

    considered necessary. Working capital although required

    "up-front", also has a residual value at the end. Inventory

    can be sold off and cash value realized on completion of the

    plant life.

    Operating Costs

    Figure 1.4 lists the typical items that go into the make-up of

    operational costs. These are costs which, in general , are

    proportional to the plant throughput. They are necessary to

    run the plant.

    The major operating costs of a process plant are the costs of

    feedstock, raw materials, utilities and other consumables.

    It is not un usu al for t he a nn ua l cost of feedstock an d ut ilitiesfor a process plant to exceed the capital cost by a significant

    factor. This is often recognized by the fact th at a m ajor rea son

    for considering a new plant is the availability of feedstock,

    raw materials or a key utility at an especially advantageous

    price. In many cases, the physical location of the plant

    may be dictated by the location of available feedstock or

    Normally, an investor or developer will want to make sure

    that there is a guaranteed source of feedstock and supplies

    of key utilities at fixed prices. Long time contracts may be

    signed, in advance, for the supply of feedstock and utilities.Such a m ove may go a long way in r educing the m ajor pa rt of

    the risk in a new project venture.

    Product Revenues

    The key objective of the project is to earn revenue from the

    sale of the products. For the project to be successful, there

    must be a secure mar ket. The main featur es that marketers

    will attempt to establish are (1) Is there a demand for the

    products and will this continue or preferentially increase

    over the life of the project? and (2) Will the price of the

    products r ema in st able or in crease over t he life of th e project?

    The total profitability of the project is set by the margin

    between the cost o f p roduct ion and the se l l ing pr ice of

    products. The selling price must be competitive initially and

    so far as can be seen remain competitive over the life of the

    project. The potential markets should be identified and the

    ability of the buyers to pay must also be evaluated. Many a

    project has failed because although there was a need for the

    product, the buyers did not have the capacity to pay. Most

    astute developers will attempt to negotiate long-term "baseload" sales contracts at preferential prices. They will find a

    financially sound buyer who will take a substantial portion

    of the product at a rate that is at tractive and guaranteed

    over a period of five or more years. This establishes a base

    operating level and a base income for the project.

    The operating level is also a key to project success. Large

    plants benefit from "economies of scale". A large throughput

    achieves higher operating efficiencies and also allows many

    fixed or sem i-fixed costs t o be dist ribu ted over h igher volumes

    of product result ing in a lower unit cost . The theory of economy of scale is admirable if there is demand for the

    volume of product produced. Large plants can be big money

    losers if they are not run at full capacity. In any feasibility

    study, the level of plant operation is a major contributor to

    overall profitability.

    Economic Factors

    Economic factors, in gener al, cann ot be pr edicted over a long

    period. These include the rate of inflation, interest levels,

    foreign currency exchange rates, and the general businessclimate. Interest, inflation and foreign currency exchange

    rates can be built up in the econometric model to see the

    effect on profi tabil i ty . Different high/low rates may be

    selected over the life of the project to determine the best

    and worst that could happen. From this, the profi tabil i ty

    risk can be established. In some cases it may be possible

    to hedge against adverse conditions by buying forward or

    by inco rpo ra t ing ad jus tmen t s o r e sca la t ion c lauses in

    contracts.

    Government Influences

    City, state a nd centra l governm ents can have a major impa ct

    on a project. New taxes may be introduced or existing rates

    may be changed. Regulations may be passed, particularly

    with regard to environmental concerns, that may require

    additional capital expenditure and add to the operat ing cost.

    Tax incent ives may be made to compet i to rs in another

    location.

    Nothing can be done about future government influences.

    The best that can be done is to pick up an area where the

    government seems stable. Look carefully at the history andcheck out al l pending legislat ion. Select backward areas

    offering tax concessions over the life of the project.

    The Econometric Model

    The first step in preparing an econometric model is to set

    up t he columns and rows required. In t he example given h ere,

    the operating life of the plant will be 10 years, with a three

    year construction period. A column of values will be required

    for each year. An initial design value and a final value are

    also needed. A reference column and a description columncomplete the picture resulting in 17 columns overall. These

    are labeled A through Q.

    The rows under the columns now deal in sequence with the

    fac tors a l ready descr ibed to g ive the f inancia l p ic ture .

    Reference should be made to the econometr ic model in

    Figure 1.5. This model is an example to illustrate method

    and technique. The actual values are not necessarily in line

    with commercial practice.

    C o l u m n H e a d i n g s : Columns a r e iden t i f i ed wi th the i rheadings and year numbers.

    General Factors

    u Row 1: Avera ge Inflat ion Ra te, per cent . This row shows

    the predicted rate of annual inf lat ion for the entire

    project life of 13 years.

    u Row 2: Compounded Escalation factor (CEF). Row 2

    converts row 1 into a compounded multiplier. CEF for

    year

    N = (1+I1/100)x(1+I2/100)..x(1+IN/2/100). For year N

    average inflation rate is taken at mid year point, hence

    N/2.

    u Row 3: Plan t Opera ting Rate, per cent (POR). The plant

    operat ing rat e is a key variable in the profitability study.

    A 60% operating rate is considered for year 1 rising to

    100% over the first five years.

    Activity 1E

    List out economic factors that

    could affect profitability of yourproject. Establish their trend ofchanges based on the analysisof data of recent previous years.

    residual, this value equates to plant cost minus scrap

    value divided by plant life. There are different methods

    of calculat ing depreciat ion. This is the straight l ine

    method.

    u R o w 2 7 : Deprecia ted Book Value , $M. This i s an

    accounting Figure and is equal to the capital cost minus

    th e residual value minus the a nnu al depreciation to date.

    u Row 28: Actual Annual Profit, $M. This value is the

    total annual revenues (Row 23) minus the total annual

    o p e r a t i n g c o s t s ( R o w 1 6 ) a n d m i n u s t h e a n n u a l

    depreciation (Row 26).

    u Row 29: Discounted Annual Profit, $M. This converts

    the annual profit in row 28 to the present day value by

    dividing the actual annual profit by the compounded

    escalation factor (Row 2).

    discoun ted an nu al pr ofit (Row 29) is divided by the t otal

    initial design capita l cost to give the ROI. The fina l value

    gives the average over the plant life.

    Loan Alternative

    The econometric model up until now has assumed that all

    the capital needed will be provided by the XYZ company.

    An alternative to this is to raise a loan with fixed interest

    rate over the project life including the construction period.

    The loan repayment will be fixed and can be considered as

    operating cost. The balance of any profit and the residual

    cost a re t hen a vailable to the compan y and can be r elated to

    a lower investment cost.

    To check out the economics of this alternative, a case is

    assumed such that $250M is taken as loan over a 13 year

    period. An additional $125M is raised as capital by the XYZ

    shareholders.

    u Row 31: Loan/Interest Repayment, $M. This shows the

    annua l in te r es t due on $250M loan a t 18% s imp le

    in teres t .

    Activity 1H

    Modify econometric model of

    your project by assuming debtequity ratio of 1:1, i.e. projectfinancing through 50% loan and50% equity.

    u Row 32: Cumulative Cash Flow, $M. This is the same

    as row 24 except t he project sta rts with $375M in h and

    and $45M in interest is paid out each year.

    u Row 33: Cash Retained, $M. Available cash initially

    exceeds requirements. Later excess cash is retained to

    build up capita l to pay off the loan. To compa re t he loan

    alternative with the base case, the final cash retained

    equals the loan plus investment capital , leaving the

    residual value the same as the base case.

    u Row 34: Interest on Cash in Hand, $M. The excess cash

    in hand will earn interest. It is assumed that interest

    will be earned at the annual inflation rate in Row 1.

    u Row 35: Declared Annual Profit, $M. In this case profit

    can be declared at any level supported by the cash flow

    less the cash retained.

    u Row 36: Discounted Annual Profi t , $M. This is the

    present or the discounted value of the annual profit.

    Row 35 is divided by CEF.

    alternative, the profit is divided by the shareholders'

    capital of $125M only since this is t he sh ar eholders' t ota l

    investment. As can be seen, although the total profit

    earned is lower, the ROI is considerably higher due to

    the reduced investment.

    Analyzing the Financial Picture

    Now that the econometric model is complete, it is possible

    to examine the profitability of the venture. The base case

    yields an average annual ROI of 20.72% over the 10 yearswhich is at t he desired t ar get level. Actu ally, th e profita bility

    ma y be higher t ha n sh own, since not all th e working capita l

    is expended initially and some interest could be earned on

    excess cash in hand . Also the r e s idua l va lue p lu s the

    depreciated value exceeds the initial investment. If desired,

    the econometr ic model could be adjusted to show these

    details, however, the base case results shown are probably

    close enough for analysis and decision making.

    Activity 1I

    Calculate ROI for the following

    two alternatives of your projectfinancing :

    - 100% equity

    - 50% equity and 50% debt(loan).

    Modifying the Variables

    Now that the econometric model has been set up, unlimited"What if" simu lat ions ma y be car ried out to see t he effect on

    the bottom line. The inter-meshing equations on the spread

    sheet instantly adjust all related values in the columns and

    rows to show the new picture. To illustrate this, following

    five "what ifs" are simulated.

    u Case A. Project capital cost overruns by 50%.

    u Case B . Annual inf lat ion rate runs 15% higher than

    predicted rate.

    u Case C. Operating rate runs 10% lower than hoped forin first five years.

    u Case D. Due to competitive market, proposed price of

    product A to ABC company must be reduced by 10%.

    u Case E . Market for product B is less buoyant than

    anticipated, cut by 20%.

    All of these changes can be entered singly or in combination

    and the spread sheet will instantly adjust. Figure 1.6 shows

    the effect on the annual discounted ROI per cent of each of

    the above "What ifs" and compares the changes against the

    base case.

    Activity 1J

    factors on the profitability of yourproject as illustrated in this Unit.

    The analysis of contingency, risk and sensitivity analysis isan essential part of capital cost estimation. An estimate, by

    definition, is an approximate computation of the probable

    cost. It is unusual that the project final cost matches the

    initial estimate. Those who are unfamiliar with estimating

    methods may expect more details and more accuracy in an

    estimat e tha n is achievable. There ar e so ma ny variables an d

    unknowns at the time an estimate is prepared that arriving

    at a reasonably close overall cost estimate is more art than

    science. Skill and judgment is needed to identify and predict

    the unknown.

    Those unfamiliar with estimating methods are more likely

    to accept a contingency figure which can be supported by

    analysis than a number which appears to be someone's best

    guess. Simple systems, which can be readily applied to a

    variety of estimates for the analysis of contingency and risk,

    are described hereunder.

    Object ives

    After reading this unit, you will be able to:

    y Establish risk components in project cost estimates

    y Establish the sensitivity of cost estimates to various riskcomponents

    y Provide appropriate contingency in the cost estimates to coverthe risk factors

    Activity 2A

    Write down the risk factors in cost

    estimates of your project.

    Definitions

    The following are generally accepted definitions:

    u Contingency: A provision for an occurrence dependent

    upon chance, accident or uncertain event.

    u Risk: Exposure to mischance, danger, hazard, injury,

    damage, bad consequence or loss.

    u Sensit ivi ty: The quality of being keenly susceptible and

    responsive to external forces.

    u Analysis: A separating or breaking up of any whole into

    i ts par ts so as to f ind out the i r na ture , p ropor t ion ,

    function and relationship.

    Types of Project Estimates

    Contingency, risk and sensitivity analysis can be applied to

    any part of a project cost estimate such as:

    u Fixed capital

    u Working capital

    u Operat ing cost

    Here we will discuss the application of contingency, risk and

    sensitivity analysis to the fixed capital cost estimates. The

    concept can equally apply to working capital and operating

    cost estimates.

    Fixed Capital Cost Estimation

    The f i r s t s t ep in the p repa ra t ion o f f ixed cap i t a l cos t

    estimates is to sub-divide the project into its units or areas.A typical refining or a petrochemical complex may be sub-

    divided as shown in Figure 2.1. This is not intended to be a

    complete list. It merely illustrates the first step in breaking

    down an ove ra l l complex in to spec i f i c un i t s , a r eas o r

    categories to facilitate cost estimation.

    The next step is to take each of these major subdivisions and

    apply a common code of accounts which will apply to all

    project subdivisions as shown in Figure 2.2.

    techniques and the use of common codes of accounts assist

    with the build up of cost statistics and the transfer of cost

    data and ratios from one project to another.

    Estimate Accuracy

    Having prepared the unit and overall project estimates, the

    next question is "What is the accuracy?" A higher level of

    accuracy may be expected than is realistic. However, if the

    accuracy probabi l i ty i s assessed by a formal analy t ica l

    p rocedu re , then i t w i l l be more l ike ly tha t a r ea l i s t i c

    contingency will be set.

    The accuracy of an es t imate depends upon the pro jec t

    def in i t ion and a lso on the t ime and ef for ts spent on i t s

    preparation. Figure 2.5 indicates typically the probable

    accur acy of estima tes at each pr oject definition st age. Moving

    At stage 0, when the project is still in the initial conceptual

    phase, an order of magnitu de estimat e may ha ve an a ccura cy

    of between 30 to 50%.

    At s tage 1, when p rocess des ign has been f ina l i zed , a

    preliminary or factored estimate from equipment costs may

    be prepared with an accuracy of between 15 to 25%.

    At stage 2, when basic engineering is complete, i.e. piping

    and ins t rumenta t ion d iagrams, p lo t p lans , a r rangement

    studies etc. have been completed, a definitive estimate can

    be prepared with an accuracy of 10 to 15%.

    At stage 3, on completion of engineering wh en final d ra wings

    and bills of materials have been completed and all material

    has been pur chased, a deta iled estimate can be prepared with

    an accuracy of 5 to 10%.

    Stage 4, corresponds to mechanical completion of erection,

    but even at this time, the final actual cost of project is not

    known precisely.

    The last stage 5, at financial completion, is when the final

    actual cost is known which is when all the bills have been

    sett led. This may be af ter several months of mechanical

    completion.

    If the above ranges of accuracy are typical and has been

    proved by experience from many projects, then if one can

    define the stage of project definition, the likelihood is that

    t h e a c c u r a c y w i l l f a l l s o m e w h e r e i n t h e s h a d e d a r e a

    indicated. It follows that an average contingency within the

    range shou ld be a l lowed , depend ing upon the spec i f i cproject.

    Figure 2.5 also indicates that the accuracy is related to the

    proximity to the completion date. An estimate is more likely

    to be accurate if the time to completion is reduced. If there

    is a long schedule period, the probabil i ty of inaccuracy

    increases.

    The Need for a Contingency

    Regardless of the time and effort spent in preparation of anestimate, there is always the possibility of errors due to:

    u En gineering err ors an d omissions

    u Cost and rate changes

    u Construction problems

    u Schedule s lippages

    u Miscellaneous unforeseen

    u Estimating inaccuracies

    D u r i n g t h e p r e p a r a t i o n o f t h e e s t i m a t e , e a c h i t e m i s

    costed by estimating the man-hours or material content and

    applying a cost rate. At the preliminary est imate stage,

    This is covered by a design margin applied to the equipment

    and bulk mater ia l ca tegor ies and is an in tegra l par t o f

    The contingency is required to cover those events which

    could occur during progress of any normal project. Complete

    coverage to cover wor s t poss ib i l i t i e s cou ld r equ i r e a

    significant contingency for each code of accounts. The sum

    of these con t ingenc ies wi l l g ive a ve ry l a rge ove ra l l

    contingency for the total project.

    The probability that things will go wrong on all accounts is

    unlikely. Therefore, the overall contingency does not need

    to be the sum of the maximum individual contingencies. It is

    an average cont ingency tha t should be adequate i f i t i s

    assumed that not all things will go wrong and some things

    may go better than planned. The practice, therefore, is to

    determine average contingency for each account. This is

    totaled and kept as a separate overall contingency, available

    to the project as a whole.

    Prepare a contingency

    worksheet of your project in linewith Fig.2.6.

    Method of Determining Contingency

    The method of arriving at a reasonable contingency requires judgmen t . So , i t i s des i r ab le tha t a cons i s t en t log ica l

    procedure be used in its development. The procedure should

    separa te wha t m ay be term ed "average contingency" and the

    "ma ximum risk cont ingency," which would be t he contingency

    required to cover the worst case.

    Average contingency is determined by examining the project

    definit ion stage for each code of accounts and applying

    average es t imat ing accuracy fac tors appropr ia te for the

    specific project. The maximum risk contingency (discussed

    later) is determined by examining problem areas in each codeof accounts.

    The average accura cy ranges ar e tak en from t he chart shown

    in Figure 2.5 for each stage of definit ion. The probable

    accuracy selected for a specific project will be within the

    ranges shown in Figure 2.5 for each stage. Whether the

    Figure selected will be at the top or bottom end of the range

    will be determined by the variables and unknowns for the

    specific project.

    For example, a Gulf Coast project for a conventional process

    unit would be at the lower end of the range, while a non-

    standard process unit at an overseas site would be at the

    upper end o f the r ange . P rocess unknowns , sou rces o f

    engineering, procurement and construction, the schedule

    period, market and economic factors could all influence the

    selection of the probable accuracy for the specific project.

    Following this evaluation, a chart as shown in Figure 2.6 is

    drawn up for the specific project being evaluated.

    To evaluate the average contingency, a standard worksheet

    form is used as shown in Figure 2.7.

    Figure 2.7: Conting enc y Workshe et Form

    Columns 1 & 2 on the left hand side of the form list the

    equipment and bulk materials by code of accounts. The form

    may be subdivided under material, subcontracts and labour

    in a similar manner to the way in which the unit estimate is

    built up.

    Column 3 shows the current estimate value or most recent

    forecast value in dollars.

    Colum n 4 expresses the value in column 3 as a percentage of

    the es t imate to ta l . This i s used for sensi t iv i ty analysis

    (discussed later).

    Column 5 through 10 indicate the percentage of column 3

    that has been defined through to the stage indicated. For

    example, if the project is in the initial conceptual stage, then

    it will show 100% under stage 0. If the account has passed

    through the definit ive est imate stage and 50% has been

    purchased, then 50% would be at sta ge 2 and 50% at st age 3.

    The object is to identify the degree of definition for the

    account by al locating the total 100% in the appropriate

    columns from stage 0 to stage 5. This allocation need not be

    too precise. It can be perform ed on a n a pproxima te judgmen t

    basis. I t is of par t icular value if the project est imate is

    reviewed at periodic intervals and contingency reevaluated

    i s to iden t i fy the major i tems of r i sk and to assess the

    maximum cost impa ct of the risk. The next step is to at tempt

    to assess the percentage probability that this risk will occur.

    The net risk then becomes the multiple of the maximum cost

    of the risk times the probability. The sum of all the net risks

    for each of the risk possibilities gives the total maximum

    risk contingency required (see Figure 2.8).

    a v e r a g e c o n t i n g e n c y e v a l u a t i o n a n d a m a x i m u m r i s k contingency evaluation. Again an overall contingency put

    into an estimate need not necessarily be the sum of these

    two. I t requires judgment to assess which number i s a

    reasonable contingency to apply against t he estima tes. It may

    be policy to include the two contingencies as separate items

    i.e. including the a verage cont ingency as pa rt of th e estima tes

    and m ainta in a ma ximum risk contingency as a separ ate fund

    to offset any major risk items that have been identified.

    SensitivityHaving carried out the contingency and risk analysis, the

    last step is to do a sensitivity analysis. The term may be

    interpreted in many ways. But in general, the requirement

    is to determine cost areas which could change significantly

    and which, in turn, would have the greatest impact on the

    overall project cost which will be more sensitive to changes

    in some accounts than others. For example, if one account

    represents 1% of the total cost, then a 100% overrun in this

    account will only effect the total by a maximum of 1%. On

    th e other han d, if another account represents 20% of the t otal

    cost, then a 10% overrun on this account could affect the

    total cost by 2%. Thus the total cost has greater sensitivity

    to this account than the first.

    As the project proceeds, so sensitivities will change as some

    of the accounts become firm and committed. Sensitive areas

    will be those accounts which still have the largest dollar

    va lues ye t uncommi t t ed and wh ich r equ i r e the l a rges t

    contingency.

    The analysis o f average and maximum r isk cont ingency

    provides an effective means of establishing sensitivity. A

    qu ick r ev iew o f the r equ i r ed ave rage con t ingency and

    maximum risk contingency against each of the account codes

    will indicat e ra pidly the potent ial ar eas with high sensitivity

    i.e. the cost accounts which may have the maximum effect

    on the total cost forecast both in the areas of overruns and

    potential cost savings. It is, therefore, a valuable exercise to

    identify the highly sensitive areas. Following on from this,

    one may introduce some additional surveillance with checks

    and balances in these areas to a t tempt to min imize the

    potential overrun and maximize the potential for reducing

    the overall project cost.

    Having performed a review of each account for average and

    maximum contingency to identify potential areas of high

    sensitivity, the next step is to identify the impact of any

    spec i f i c cos t changes . Fo r example , changes in l abo r

    productivity, cha nges in wa ge ra tes or exten sion t o the pr oject

    schedule. For specific risks of this type, sensitivity covers

    can be constructed to show the impact of these cost changes.

    Figure 2.9 illustrates two types of such curves. The first

    shows the e f f ec t on l abou r cos t o f chang ing l abou r

    productivity combined with the changes in the labour cost

    rates. As can be seen, the total labour cost is extremely

    sensitive to reduction in labour productivity, more so than

    increase in labour rate.

    The second chart shows the effect of increased schedule time

    on project cost. It shows, for example, that the effect on

    A new project is "initiated" when owner and contractor enter

    into a contract or agree to start work with "letter of intent"

    while the contract is being finalized. From the contractor's

    viewpoint, the owner has now become the "client".

    Manpower Build-up

    In order to build a plant, an Engineering & Construction

    (E&C) contractor must spend money at the proper rate to

    meet the required completion schedule. Money translates

    to man-hourswhether it is home office engineering hours,manufacturing hours or field construction hours. To achieve

    progress, man-hours must be spent. On a project where short

    schedule is of prime importance, calendar time can be saved

    by selecting designs already completed, standard equipment

    already fabricated, or material in stock. Even when these

    methods are used, there are still a large number of hours in

    engineering, manu facturing a nd const ruction which must be

    expended during the project execution.

    Object ives

    After reading this unit, you will be able to:

    y Understand the basic steps required to be taken at the time ofinitiating a project

    y Explain importance of the various initiation steps at project initiationstage

    y Explain how an effective communication channel should beestablished with the client and other team members

    y Emphasize importance of freezing project technical data at theinitiation stage itself

    Activity 3A

    Make a list of the major initiation

    steps for your project.

    The E&C must achieve a rapid mobil ization and smooth

    application of man power, without flat periods, fluctuations,

    or excessive peaks, which will match the project budget and

    schedule. This is where the skill of E&C plays an important

    part. Figure 3.1 shows the relationship between home office,

    manufacturing and construction man-hours. The solid curves

    show the desired rate of mobilization and build-up with rapid

    spread of work through manufactur ing and const ruct ion

    giving optimum peak manpower application consistent with

    the needs of the project schedule. The dotted curves show

    the impact if early engineering is delayed. This results in

    s t e e p e r m o b i l i z a t i o n c u r v e s i n m a n u f a c t u r i n g a n d

    construction with higher man-power peaks which, in turn,

    lead to inefficiency and greater cost.

    Figure 3.1 illustrates the importance of a fast engineering

    start. Every man hour below the optimum curve during the

    early engineering phase may add four to five times these

    hours to the peak du ring the m anu facturing an d constr uction

    phases if the scheduled end date is to be met. Conversely,

    overstaffing in the early phases ahead of date development

    will also lead to inefficient man hour utilization.

    Major Initiation Steps

    As soon as a project has been awarded, a project manager(PM) begins a ra ce against time a s th e leader of a tea m, when

    th e team, th e rules and the course m ay yet have to be defined.

    The initiation of a project puts great pressure on him to get

    the project moving. Table 3.1 lists the steps in the initiation

    of a project. The list is not compr ehens ive but shows th e more

    important activities of a project manager.

    These steps do not necessarily occur sequentially. Several

    may occur in parallel. The list in Table 3.1 can be assembled

    into an activity network as shown in Figure 3.2. All of theseactivities should be undertaken within the first few weeks

    of project awa rd. E ach of the a bove steps is described in more

    details below.

    Prior to the project award, the E&C would probably have

    submitted technical and commercial proposals. PM's job of

    initiating a project may be easier if the proposal period has

    been fairly extensive and the E&C has spent a considerable

    t i m e a n d e f f o r t i n p r e p a r i n g d e t a i l e d t e c h n i c a l a n d

    commercial proposals.

    At the time of award, the scope of the project may have

    changed f rom the enquiry document . The proposal may

    have been modif ied, added to or adjusted by a ser ies of

    let ters or clar if ication meetings held pr ior to the award.

    I t i s e ssen t i a l tha t PM ca re fu l ly check th rough a l l o f

    the proposal documentation and assemble a complete file

    o f p roposa l documen ts , l e t t e r s , t e l exes , t e l ephone and

    meeting notes. He thus has a complete record of what was

    requested, what was offered and what was accepted in the

    To ensure continuity and a smooth job start, the E&C will

    want to involve the nominated PM and the key members of

    the proposed project team in the proposal activities and pre-

    awar d contr act discussions.

    Establish Client Communication Channels

    If a PM is to maintain control over the project , he mustesta blish with t he client t ha t h e is the official comm un icat ion

    channel between the E&C and the client for all major aspects

    of the project. During the proposal stage, contacts with the

    client may have been many and varied from commercial,

    project and process engineering, legal, financial and others.

    Client ma y have become used t o dealing with mu ltiple people

    and expect to continue to do so.

    PM has to take over the scene delicately but firmly both with

    th e client a nd within his own organizat ion. This ensures t hat

    all fut ure commu nicat ions a re chann eled th rough h im so that

    he can maintain control. He will recommend to the client

    that similar arrangement is followed in client's organization.

    A client PM should be appointed through whom all major

    commu nicat ions a re channeled. This does not mean tha t t here

    i s n o c o m m u n i c a t i o n o r d i r e c t c o n t a c t b e t w e e n o t h e r

    members of the client and contractor's organization. It does

    mean that any such contacts/communications are either in

    th e presence of PM or with his pr ior k nowledge and t hat the

    subject matter is properly recorded and approved by the PM.

    Client Kick-off Meeting

    As soon as possible, after project award, PM should hold a

    kick-off meeting with the client and go through a check list

    to make sure tha t there i s to ta l agreement be tween the

    contr actor and client with r egar d to th e project requirements.

    A comprehensive project procedure is necessary for effective

    covering equipment, materials and services which must then

    be adapted to suit the specific project. The basic areas to

    which project numbering system and procedures are applied

    are :

    u Tagging and identification of equipment and materials;

    u Numbering of technical documents, specifications, data

    sheets, drawings, requisitions and purchase orders;

    u Procurement commodity codes;

    u Scheduling activities in engineering, procurement and

    u Estimating equipment, materials and services;

    u Recording man hours on timesheets in the home office

    and field;

    u Recording project scope changes;

    u Project accounting and invoicing;

    u Project cost and progress reporting;

    u Project document management.

    In addit ion, a large project must be subdivided into i ts

    various units, areas and plant elements to facilitate control

    and reporting. Too great a degree of subdivision merely adds

    to work and confusion. The best solution is to have the

    minimum number of sub-project numbers which will give

    reasonab le con t ro l . On a ma jo r mu l t i -un i t p ro jec t , t he

    following breakdown is recommended:

    u Overall project number for summary cost reports and

    comm on/bulk r equirement s;

    u I n d i v i d u a l s u b - p r o j e c t n u m b e r s f o r e a c h m a j o r

    identifiable process unit within the complex;

    u One or more sub-project numbers for off-site systems,

    depending upon size and scale;

    distinct locations such as marine terminal, remote road

    or rail loading or dispatching stations etc.

    Prepare Project Plan

    On completion of the above steps, PM should prepare a

    p ro jec t p lan . Th i s p lan de f ines the p ro jec t ob jec t ives ,

    priorities and philosophies. Its preparation fulfills a number

    of functions:

    u It requires that the PM, as leader of the project, takes

    the t ime to access the project needs at an ear ly date

    and present his intended plan of execution. Individual

    communications or meetings are no substitute for the

    writ ten plan.

    u It provides a basic reference and briefing document for

    those who wi l l u l t ima te ly be invo lved in p ro jec t

    execution.

    u I t a l lows the E&C management to rev iew the p lan ,

    p r o v i d e g u i d a n c e a n d a s s i s t a n c e a n d , t h e r e a f t e r ,

    support the plan throughout project execution.

    The project plan wil l normally include background data;

    scope of work and services by E&C and client; split of work

    with others (process licensors, other contractors); basis of

    con t r ac t ( l i ab i l i t i e s , gua ran tees ) : r egu la to ry and o the r
