1.0 Introduction
All municipal engineers and managers involved in urban infrastructure projects,
frequently face problems in terms of cost estimates, economic and financial
analysis, rate analysis, project benefit cost analysis etc. The question is how to
tackle these aspects to predict or assess cost, how to minimize the risk and
impact of overspends against budgets, and how to ensure that there is an
appropriate balance between technical aspects and the related costs.
Therefore this module has been structured to include the following components
• Overview of SOR and Rate analysis
• Sample infrastructure project cost estimates
• Key concepts of project viability
• Project financial and economic analysis
2.0 Schedule of Rate (SOR) & Rate Analysis Estimation of the project cost is necessary for evaluation of the required
investments in any project. The construction industry is an ocean of activities and
details, too many items descriptions and tiny technical differences but even these
apparently tiny and miniscule detail differences change and affect the analysis,
application of these activities.
The item when is translated into a monetary value through a technical analysis of
the composition of its constituent activities is termed as analysis of Rates. This is
to arrive at a rate based on unit which can subsequently be multiplied with the
quantity of units is called as the item-rate.
A composition of the body made with all the item description, specifications and
rates is commonly termed as the Schedule of Rates. Since the subject of
Schedule of Rates has been raised it is important to understand that whenever
term SOR is applied it indirectly or directly is inferred that one is talking about an
activity or a set of activities pertaining to construction.
Therefore, to understand and interpret a Schedule of Rates (herein after referred
to as the SOR) means working at the various aspects of the item description,
specifications and Rate analysis template.
The SOR forms the basis for most of the developmental works carried out by the
Government. All Government projects use SOR either specific to a particular
department or developed by some other department. The SOR is taken as the
datum for estimation, selection of most competitive bidder, extra item
settlement, cost escalations, dispute redressed, arbitration and award of work.

Module 2.6: Engineering Economics
Like all other states in the country, various state departments all use SORs for
diverse developmental activities. Although, the Schedule of Rates (SOR) prepared
by The Public Works Department (R&B) forms the basis for all other SORs, many
of the departments and organizations have developed their own SORs, at various
time intervals and for divergent needs.
2.1 Need for SOR The SOR is the single most important factor in the preparation of the tenders and
estimates of various developmental works carried out under various departments.
The entire estimates and the projections, awards and arbitrations are based on
these rates that are applied to the items under the development. The costs and
estimates of the various projects and developmental works such as roads,
buildings, bridges, culverts, irrigation, water supply and sewerage projects,
maintenance works depends mainly on the quality and accuracy of the SOR.
2.2 Rate analysis Rate analysis for different activities / items under a project is one of the most
important steps towards estimation of project cost. Comprehensive approach to
rate analysis is given in the table2.1 below.

3.0 Bill of Quantity (BOQ) Bill of Quantity comprise a list of items of work which are briefly described. The
Bills also provide a measure of the extent of work and this allows the work to be
priced. The work included in the item is defined in detail by the rules in the
Method of Measurement. The item descriptions are therefore shorthand to allow
the relevant rules of the Method to be identified. The measure may be a single
item or number, dimension (linear metre, square metre, cubic metre), time (hrs,
weeks) or weight.
Function of Bills • The Bills of Quantities may serve a number of functions as:
• A breakdown of the tendered price, with no contractual status, but providing
information for the selection from tenderers;
• An estimate measure of the work for the tendered price, to be used to arrive
at a revised contract price once the actual quantities of work carried out are
measured. This is the re-measure form of contract.

4.0 Financial Analysis of Infrastructure Projects To judge a infrastructure project from the financial angle, an engineer needs
information about the following two most important aspects:
• Cost of project
• Projected cash flow
4.1 Cost of Project Project cost estimating is usually performed by summing estimates for individual
project elements into a project total. The pieces can vary in size and number from
a few large chunks of a project with known costs to hundreds or thousands of
discrete tasks or individual work packages.
Conceptually, the cost of project represents the total of all items of outlay
associated with a project which are supported by long-term funds. It is the sum
of the outlay on the following;
• Land and site development
• Buildings and civil works
• Plant and machinery
• Technical know-how and engineering fees
• Miscellaneous fixed assets
• Preliminary and capital issue expenses
• Pre-operative expenses
• Provision for contingencies
• Margin money for working capital
• Initial cash losses
4.1.1 Technical Know-how and Engineering Fees Often it is necessary to engage technical consultants or collaborators from
India/or abroad for advice and help in various technical matters like preparation
of project report, choice of technology, selection of plant and machinery, detailed
engineering, and so on. While the amount payable for obtaining technical know-

Module 2.6: Engineering Economics
how and engineering services for setting up the project is a component of project
cost, the royalty payable annually, which is typically a percentage of sales, is an
operating expense taken into account in the preparation of the projected
profitability statements.
4.1.2 Miscellaneous Fixed Assets Fixed assets and machinery which are not part of the direct manufacturing
process may be referred to as miscellaneous fixed assets. They include items like
furniture, office machinery and equipment, tools, vehicles, railway siding, diesel
generating sets, transformers, boilers, piping systems, laboratory equipments,
workshop equipments, effluent treatment plants, fire fighting equipments, and so
on. Expenses incurred for procurement or use of patents, licenses, trade marks,
copyrights, etc., and deposits made with the electricity board may also be
included here.
4.1.3 Preliminary and Capital Issue Expenses Expenses incurred for identifying the project, conducting the market survey,
preparing the feasibility report, drafting the memorandum and articles of
association and incorporating the company are referred to as preliminary
expenses.
Expenses borne in connection with the raising of capital from the public are
referred to as capital issue expenses. The major components of capital issue
expenses are : under writing commission, brokerage, fees to managers and
registrars, printing and postage expenses, advertising and publicity expenses,
listing fees and stamp duty.
4.1.4 Pre-operative Expenses Expenses of the following types incurred till the commencement of commercial
production are referred to as pre-operative expenses: (i) Establishment expenses,
(ii) rent, rates and taxes (iii) travelling expenses, (iv) interest and commitment
charges on borrowings, (v) insurance charges, (vi) mortgage expenses, (vii)
interest on deferred payments, (viii) start-up expenses, and (ix) miscellaneous
expenses.
Pre-operative expenses are directly related to the project implementation
schedule. So, delays in project implementation, which are fairly common, tend to
push up these expenses. Appreciative of this, financial institutions allow for some
delay (20 to 25%) in the project implementation schedule and accordingly permit
a cushion in the estimate for pre-operative expenses.

CEPT, Ahmedabad 26
Module 2.6: Engineering Economics
Pre-operative expenses incurred up to the point of time the plant and machinery
are set up may be capitalized by apportioning them to fixed assets on some
acceptable basis. Pre-operative expenses incurred from the point of time the
plant and machinery are set up are treated as revenue expenditure. The firm
may, however, treat them as deferred revenue expenditure and write them off
over a period of time.
4.1.5 Provision of Contingencies A provision for contingencies is made to provide for certain unforeseen expenses
and price increase over and above the normal inflation rate which is already
incorporated in cost estimates.
To estimate the provision for contingencies the following procedure may be
followed: (i) Divide the project cost items into two categories, viz, ‘firm’ cost
items and ‘non-firm’ cost items (firm cost items are those which have already
seen acquired or for which definite arrangements have been made). (ii) Set the
provision for contingencies at 5 to 10 percent of the estimated cost of non-firm
items. Alternatively, make a provision of 10 percent for all items (including the
margin money for working capital) if the implementation period is one year or
less. For every additional one year, make an additional provision of 5 percent.
4.1.6 Margin Money for Working Capital The principal support for working capital is provided by commercial banks and
trade creditors. However, a certain part of working capital requirement has to
come from long-term sources of finance. Referred to as the ‘margin money for
working capital’, this is an important element of the project cost.
The margin money for working capital is sometimes utilized for meeting over-runs
in capital cost. This leads to a working capital problem (and sometimes a crisis0
when the project is commissioned. To mitigate this problem, financial institutions
stipulate that a portion of the loan amount, equal to the margin money for
working capital, be blocked initially so that it can be released when the project is
completed.
4.1.7 Initial Cash Losses Most of the projects incur cash losses in the initial years. Yet, promoters typically
do not disclose the initial cash losses because they want the project to appear
attractive to the financial institutions and the investing public. Failure to make
provision for such cash losses in the project cost generally affects the liquidity
position and impairs the operations. Hence prudence calls for making a provision,
overt or convert for the estimated initial cash losses.

4.2 Project Cash Flow In engineering many times an engineer comes across many alternatives.
Sometimes they have a proposal to replace the old machine by new advanced
machine. But before doing that they must evaluate the proposal’s worth.
Similarly, engineers may some time need to take decision on investing in new
projects. They may need to evaluate the investment in different infrastructure
projects. For all this, some economic indicator must be there so that the task will
be easier.
The investment decision rules may be referred to as capital budgeting techniques,
or investment criteria. A sound appraisal technique should be used to measure
the economic worth of an investment project. The essential property of sound
techniques is that it should maximize the shareholders’ wealth. The following
other characteristics should also be possessed by sound investment evaluation
criteria:
• It should consider all cash flows to determine the true profitability of the
project.
• It should provide for an objective and an unambiguous way of separating
good projects from bad projects.
• It should help ranking of projects according to their true profitability.
• It should recognize the fact that bigger cash flows are preferable to smaller
ones and early cash flows are preferable to later ones
• It should help to choose among mutually exclusive projects that project
which maximizes the shareholders’ wealth.
• It should be a criterion which is applicable to any conceivable investment
project independent of others.
These conditions will be clarified as we discuss the features of various investment
criteria herein:
A number of capital budgeting techniques are in use in practice. They may be
grouped in the following two categories.
Discounted Cash Flow (DCF) Criteria
• Net present Value (NPV)
• Internal rate of Return (IRR)
• Profitability Index (PI)
• Discounted payback period
Non-discounted Cash Flow Criteria
• Payback Period (PB)
• Accounting Rate of Return (ARR).

Module 2.6: Engineering Economics
We will show in the following the net present valued criterion is the most valid
technique of evaluating an investment project. It is generally consistent with the
objective of maximizing the shareholders’ wealth.
4.2.1 Net Present Value Method The net present value (NPV) method is the classic economic method of evaluating
the investment proposals. It is one of the discounted cash flows (DCF) techniques
explicitly recognizing the time value of money. It correctly postulates that cash
flows arising at different time periods differ in value and are comparable only
when their equivalents – present values – are found out. The following steps are
involved in the calculation of NPV:
• Cash flows of the investment project should be forecasted based on realistic
assumptions.
• Appropriate discounts should be identified to discount the forecasted cash
flows. The appropriate discount rate is the firm’s opportunity cost of capital
which is equal to the required rate of return expected by investors on
investments of equivalent risk.
• Present value of cash flows should be calculated using opportunity cost of
capital as the discount rate.
• Net present value should be found out by subtracting present value of cash
outflows from present value of cash inflows. The project should be accepted
if NPV is positive (i.e. NPV>0).
Example: Assume that project X costs Rs. 2,500 now and is expected to
generate year-end cash inflows of Rs. 900, Rs. 800, Rs. 700, Rs. 600 and Rs. 500
in years. 1 through 5. The opportunity cost of the capital may be assumed to be
10 per cent.
The net present value for Project X can be calculated by referring to the present
value table.
Rs. 900 Rs. 800 Rs. 700 Rs. 600 Rs. 500
NPV = ( (1+

) - Rs.
2,500
NPV = [Rs. 900 (PVF1,0.10) + Rs. 800 (PVF2,0.10) + Rs. 700 (PVF3,0.10)
+ Rs. 600 (PVF4,0.10) + Rs. 500 (PVF5,0.10)] – Rs. 2,500
=
[Rs. 900 X 0.909 + Rs. 800 X 0.826 + Rs. 700 X 0.751 + Rs. 600 X 0.683
+ Rs. 500 X 0.620]– Rs. 2,500
= Rs. 2,725 – Rs. 2,500
= + Rs. 225
JnNURM - Rapid Training Programme Preparation of DPRs
CEPT, Ahmedabad 30
Module 2.6: Engineering Economics
Project X’s present value of cash inflows (Rs. 2,725) is greater than that of cash
outflow (Rs. 2,500). Thus, it generates a positive net present value (NPV = + Rs.
225). Project X adds to the wealth of owners; therefore, it should be accepted.
The Formula For the net present value can be written as follows:
C1 C2 C3 CnNPV = [
(1+ k) +
(1+ k)2 +(1+ k)3 + ……… +
(1+ k)n ] - C0
or
n
CtNPV = ∑
(1+ k)t - C
0
t=1
Where C1, C2 ………represent net cash inflows in year 1,2….., k is the opportunity
cost of capital, C0 is the initial cost of the investment and n is the expected life of
the investment. It should be noted that the cost of capital, k is assumed to be
known and is constant.
4.2.2 Internal Rate of Return Method (IRR) The internal rate of return (IRR) method is another, discounted cash flow
technique which takes account of the magnitude and timing of cash flows. Other
terms used to describe the IRR method are yield on an investment, marginal
efficiency of capital, rate of return over cost, time-adjusted rate internal return
and so on. The concept of internal rate of return is quite simple to understand in
the case of a one-period project. Assume that you deposit Rs. 10,000 with a bank
and would get back the cash of a one-period project. The true rate of return on
your investment would be:
10,800 -
10,000 108,000 Rate of
Return =
10,000
=
10,000
- 10,000 = 1.08 -
1 =
0.08 or
8%
The amount which you would obtain in future (Rs. 10,800) would consist of your
investment (Rs. 10,000) plus return on your investment (0.08 X Rs. 10,000):
10,800 10000 (1.08) = 10,800 or 10,000 =
(1.08)
You may observe that the rate of return of your investment (8 percent) makes
the discounted (present) value of your cash inflow (Rs. 10,800) equal to your
investment (Rs. 10,000).
We can now develop a formula for the rate of return (r) on an investment (C0)
that generates a single cash flow after one period (C1) as follows:
C1- C0 C1r =
C0=
C0- 1
JnNURM - Rapid Training Programme Preparation of DPRs
CEPT, Ahmedabad 31
Module 2.6: Engineering Economics
Equation can be rewritten as follows:
C1
C0= 1+r
C1C0 =
(1 + r)
From above equation the rate of return can be defined as that rate which equates
investment outlay with the present value of inflow received after one period. This
also implies that the rate of return is the discount rate which makes NPV = 0. this
rate may be referred to as the internal rate of return. There is no satisfactory way
of defining true rate of return of a long-term asset. The internal rate of return
(RR) is the best available concept; although it is a very frequently used concept in
finance, yet at times it can be a misleading measure of investment worth.
Internal rate of return is called so because it depends solely on the outlay and
proceed associated with the investment and not on any rate determined outside
the investment. It can be determined by solving the following equation for r:
C1 C2 C3 Cn
C0 = (1+
r)
+
(1+ r)2
+
(1+ r)3
+ ……… +
(1+ r)n
] - C
0
n
CtC0 = ∑
(1+ r)t - C0 = 0
t=1
It can be noticed that the IRR equation is the same as the one used for the NPV
methods with the difference that in the NPV method the required rate of return k,
is assumed to be known and the net present value is found, while in the IRR
method the value of r has to be determined at which the net present value is
zero.
Uneven Cash Flows: Calculating IRR by Trial and Error The value of r in equation can be found out by trial and error. The approach is to
select any discount rate to compute the present value of cash inflows. If the
calculated present value of the expected cash inflow is lower than the present
value of cash outflows, a lower rate should be tried. On the other hand, a higher
value should be tried if the present value of inflows is higher than the present
value of outflows. This process will be repeated unless the net present value
becomes zero. The following illustration explains the procedure to calculate the
internal rate of return.

Module 2.6: Engineering Economics
Illustration:
A Project costs Rs. 16,000 and is expected to generate cash inflows of Rs. 8,000,
Rs. 7,000 and Rs. 6,000 at the end of each year for next 3 years. we know that
IRR is the rate at which project will have a zero NPV. As a first step, we try
(arbitrarily) a 20 percent discount rate. The project’s NPV at 20 percent is:
NPV = -Rs. 16,000 + Rs. 8,000 (1/1.2) + Rs. 7,000 (1/2.2)
+ Rs. 6,000 (1/3.2)
= -Rs. 16,000 + Rs. 8,000 X 0.833 + Rs. 7,000 X 0.694
+ Rs.6,000 X 0.579
= -Rs. 16,000 + Rs. 14,996
= -Rs. 1,004
A negative NPV of Rs. 1,004 at 20 percent indicates that the project’s true rate of
return is lower than 20 percent. Let us try 16 percent as the discount rate. At 16
percent, the project’s NPV is:
NPV = -Rs. 16,000 + Rs. 8,000 (1/1.16) + Rs. 7,000 (1/2.16)
+Rs. 6,000 (3/3.16)
= -Rs. 16,000 + Rs. 8,000 X 0.862 + Rs. 7,000 X 0.743
+ Rs.6,000 X 0.641
= -Rs. 16,000 + Rs. 15,943
= -Rs. 57
Since the project’s NPV is still negative at 16 percent, a rate lower than 16
percent should be tried. When we select 15 percent as the trial rate, we find that
the project’s NPV is Rs. 200:
NPV = -Rs. 16,000 + Rs. 8,000 (1/1.15) + Rs. 7,000 (1/2.15)
+ Rs. 6,000 (3/3.15)
= -Rs. 16,000 + Rs. 8,000 X 0.870 + Rs. 7,000 X 0.756
+ Rs. 6,000 X 0.658
= -Rs. 16,000 + Rs. 16,200
= -Rs. 200
The true rate return should lie between 15 to 16 percent. We can find out a close
approximation of the rate of return by the method of linear interpolation as
follows: Difference
PV required Rs. 16,000
PV ar lower rate, 15% Rs. 16,200 200
PV ar higher rate, 16% Rs. 15,943 257
r = 15% + (16% -15%)
= 15% + 0.8%= 15.8%

4.2.3 Discount Cash Flow Method (Present Value Return on Investment Method) The pay-back period and return on investment (ROI) methods do not consider the
time value of money. Projects with differing cash inflows, as follows, are treated
at par although present value return is higher in the second case. Cash flows
received in different years should not be treated to have a uniform value. Today’s
rupee is more valuable than a rupee to be received a year later. For proper and
sound financial analysis cash flows should be related to time scale.
Project I Project II
1 Year Cash inflows 8,000 Rs. 12,000 Rs.
2 year Cash inflows 12,000 Rs. 8,000 Rs.
Discounting Principle:
Let us consider that Rs. 100 is invested with 15% compound interest/annum. The
table shows earning. It shows that future value of Rs. 100 after 5 years is Rs.
201.14. The discounting principal views the whole exercise from the other end. It
puts the thing in reverse order that Rs. 201.14 to be available at the end of 5th
year is today worth Rs. 100. Therefore, the present value of the future sum of Rs.
201.14 is Rs. 100.
Year 0 1 2 3 4 5
Interest - 15 17.25 19.84 22.81 26.24
Cumulative 100 115 132.25 152.09 174.9 201.14
Discounting the future cash flows is very important in capital expenditure
appraisal. In capital investment, cash outflows take place in first year and also
spread over 2 or more years but cash inflows will start generating after the
project is commissioned and will continue during the lifetime of the project. To
arrive at a decision whether to invest funds or not, it is necessary to make a
comparison between the present value of cash outflows and cash inflows. If the
present value of cash inflows is more than that of the cash outflows, at a given
rate of discount, the capital expenditure proposal merits consideration and
approval. The trial and error method seeks to find out that particular discount
rate at which both cash outflows and inflows become equal in terms of their
present values. A number of trial calculations are made to establish the exact rate
of discount.
Merits of Discount Cash Flow Method: It considers time pattern of such flows and the present value system.
Drawbacks of Discount Cash Flow Method:
It is important that life of the asset is objectively estimated, otherwise
profitability calculations will go wrong, leading to wrong decision being taken.

Depending upon money supply, interest rate may be varying-high rate during
dear money situation an low rate during easy availability of funds. The single
discounting rate ignores the fluctuating trend of future interest rates.

proposals A & B. the proposal A requires an
investment of Rs. 60,000 and B Rs. 1,00,000 (1st
year Rs. 75,000 and 2nd year Rs. 25,000). The net
cash inflows from the investments are as shown in

For a change in rate of interest of 1! (from 16% to 17%) the change in present
value is Rs. 1,656 = (60,673 – 59,017)
The rate of interest which equalizes investment cash outflows with cash inflows is
determined as:16% + {(673 X1) /1656} =16.40%
So the proposal A yield a discounted or internal rate of return is 16.40%
JnNURM - Rapid Training Programme Preparation of DPRs
CEPT, Ahmedabad 35
Module 2.6: Engineering Economics
Similar for proposal B- actual rate of discount
= 20% + {(879 X1) /1356} =20.6482%
Thus proposal B is preferable to A as the internal rate of return is higher for B
that of A.
4.2.4 Pay Back or Pay Off Period Method Pay-back period is the time required for the net cash inflows to equal the amount
of investment i.e. the periods over which the cash inflows pay-off the investment;
the shorter the period, the better is the investment. As capital projects have a
long gestation period, during which many uncertainties may come up, the degree
of risk assumed by a company when planning capital expenditure is directly
linked to the length of time required to recover the investment from the cash
inflow generated by the project. The pay-back period takes care of this important
aspect of risk inherent in investment decisions. If there is two or more competing
project, the one having the shortest pay-back period is selected because the risk
element is the least.
Illustrative Example:
Project A Project B Investment 20,000 Rs. 20,000 Rs. Net Cash Inflows Cumulative Cumulative
1 Year 5,000 5,000 5,000 5,000

Pay-Back Period 3 year 4 year Project A is preferable to project B.
Merits of Pay off Period Method:
It is easy to calculate and can be understood easily by even non-financial people.
In time when dear money conditions are prevailing, the pay-back period method
is very suitable, because of its emphases on quick recovery of the investment
through cash inflows.
The risk element is taken care off in the pay-back period method, as it prefers a
project, which recoups the investment in the shortest possible time period.
It is most useful when the investment is not high and the capital of the project is
recovered in a short period.
The guesswork and uncertainties are less in calculations because it is not
necessary to forecast cash inflows throughout the life of the project.

Module 2.6: Engineering Economics
Drawbacks of Pay off Period Method:
This method does not measure the true profitability of the project as it does not
consider the cash inflows generated throughout the life of the project. It limits
itself to the pay-back period and ignores the cash inflows which arise after the
pay-back period. This method may, therefore, be used only as a supplementary
index along with some other method.
Another serious drawback is that time value of money is ignored. It is proper that
the cash inflows received in earlier periods should be given more value than the
cash inflows received in later periods. Without this important aspect being
considered, evaluation will not be complete and will be therefore misleading.
4.2.5 Rate of Return on Investment Method (R & I) This is an age-old technique used for evaluating capital projects. This measures
the relationship between the return after-tax and expressed as a percentage on
investment.
The rate of return is calculated as:
Average Yearly Undiscounted net cash inflow after tax X 100 CFavROI =
Total undiscounted investment cash outflows =
OF
Total undiscounted net cash flows after
tax Where CFav
=Economic life of the project
Illustrative Example: Project A Project B Total Investment 1,00,000 1,50,000
Net Cash inflows after tax during the life of the project 1,00,000 2,70,000
Life of the Project 10 years 15 years
Annual return 10,000 18,000
Return on investment 10 % 12%
Project B is preferable to Project A
Merits of Rate of Return on Investment Method:
It is a very simple and easy method which can be understood by all managers. It
is this simplicity which accounts for its wide popularity.
Unlike pay-back period method, the entire serviceable life of the project is taken
into consideration. Therefore, the project is considered in its totality.
Drawbacks Rate of Return on Investment Method:
Difficulties and uncertainties associated with the estimation of future sales and
anticipated cost over a long period are influenced by a large number of factors.
The life of an asset, for instance, would depend upon factors such as, its make,
JnNURM - Rapid Training Programme Preparation of DPRs
CEPT, Ahmedabad 37
Module 2.6: Engineering Economics
quality, the extent of its working, the state of maintenance and the manner of
handling during work.
For this method, usually profits (return) are calculated by conventional
accounting practice of taking into account accruals.
Cash flows are relevant in the context of capital investment evaluation, which
consider the time pattern of earnings. Cash generation for different projects may
be start at different points of time and hence, time pattern of cash generation is
important and relevant. Because of these limitations, the ROI technique is not
very useful to make sophisticated analysis in capital investment decisions.
4.2.6 Profitability Index Yet another time-adjusted method of evaluating the investment proposal is the
benefit-cost (B/S) ratio or profitability index (PI). It is the ratio of the present
value of cash inflows, at the required rate of return, to the initial cash outflow of
investment. It may be gross or net; net being simply gross minus one. The
formula to calculate benefit-cost ratio or profitability index is as follows :

ILLUSTRATION
The initial cash outlay of a project is Rs. 100,000 and it can generate cash inflow
of Rs.40,000, Rs.30,000, Rs.50,000 and Rs.20,000 in year 1 through 4. assume a
10 percent rate of discount. The PV of cash inflows at 10 percent discount rate is:
PV = Rs. 40,000 (1/1.1) + Rs. 30,000 (1/2.1)
+ Rs.50,000 (1/3.1) + Rs. 20,000 (1/4.1)
= Rs 40,000 X 0.909 + Rs 30,000 X 0.826 + Rs 50,000 X 0.751
+ Rs. 20,000 X 0.683
NPV = Rs 112,350 – Rs 100,000 = Rs 12,350
PI = Rs 1,12,350 = 1.1235
Rs 1,00,000
Acceptance Rule The following are the acceptable PI are :
Accept if PI > 1
Reject if PI < 1
JnNURM - Rapid Training Programme Preparation of DPRs
CEPT, Ahmedabad 38
Module 2.6: Engineering Economics
May accept if PI =1
When PI is greater than one, then the project will have
positive net present value
Evaluation of PI Method
Like the NPV and IRR rules, PI is a conceptually sound method of appraising
investment projects. It recognizes the time value of money. It is a variation of the
NPV method, and requires the same computations as the NPV method. In the PI
method, since the present value of cash inflows is divided by the initial cash
outflow, it is a relative measure of a project’s profitability.
Financial vs. Economic Analysis Financial and economic analyses have similar features. Both estimate the net benefits
of an investment project based on the difference between the with-project and the
without-project situations. However, the concept of financial net benefit is not the
same as economic net benefit. While financial net benefit provides a measure of the
commercial (financial) viability of the project on the project-operating entity, economic
net benefit indicates the real worth of a project to the country. For a project to be
economically viable, it must be financially sustainable. If a project is not financially
sustainable, there will be no adequate funds to properly operate, maintain and replace
assets; thus the quality of the water service will deteriorate, eventually affecting
demand and the realization of financial revenues and economic benefits.
It has sometimes been suggested that financial viability not be made a concern
because as long as a project is economically sound, it can be supported through
government subsidies. However, in most cases, governments face severe budgetary
constraints and consequently, the affected project entity may run into severe liquidity
problems, thereby jeopardizing even its economic viability.
The basic difference between the financial and economic benefit-cost analyses of the
project is that the former compares benefits and costs to the enterprise in constant
financial prices, while the latter compares the benefits and costs to the whole economy
measured in constant economic prices. Financial prices are market prices of goods and
services that include the effects of government intervention and distortions in the
market structure. In financial analysis, the taxes and subsidies included in the price of
goods and services are integral parts of financial prices, but they are treated differently
in economic analysis.

5.0 Financial and Economic Analysis: Case of Jammu Sewerage Project In Jammu City, there was no hygienic system for domestic excreta collection,
treatment or disposal in the city. In the older section of Jammu the obnoxious
practice of conservancy (service latrines) still continues and in other areas, the
un-treated sewage and sullage is discharged into storm water drains causing a
grave risk to health of sanitation workers and the citizens alike. Newer houses in
relatively more planned and organized colonies have septic tanks but most lack
soak ways and the partially treated effluent is usually discharged into open road
drains which flow into the natural drainage channels that pass through the city.
The components under sewerage sub projects identified are
• Completion of the ongoing construction/Laying of lateral and secondary
sewers in Division A, Phase II;
• Construction/Laying of trunk main sewers in Division A, Phase II;

Subsequent Sub project Phase I:
For these sewerage catchments separate collection systems may not be feasible
due to space constraints, congested area and narrow roads. It is therefore
proposed to provide combined sewerage system to this sewerage zone.
The component would include:
• Intercepting of sewage flowing into the Nallahs and open drains;
• Construction of trunk mains sewers, secondary sewers, laterals and house
connections;
• Provision for diversion of sewerage and storm water before entering to
treatment facility;
• Extension of treatment plant (Planned under the sample subproject) to cater
the additional requirement of 30 MLD.

Economic Analysis 1 Main Evaluation: Table 5.2 presents the results of the main economic evaluation.
The table indicates that the EIRR of the environmental sanitation component is
estimated to be 32.65%. The EIRR value exceeds the economic opportunity cost
of capital of 12% and all subprojects are economically viable. Avoided health
care costs comprise the largest proportion of economic benefits (63%) followed
by time savings in sewage disposal cost (25%) and improved property value
(11%).

1 Economic Analysis of Sample Subprojects Economic Cost: The economic costs of capital works and annual operation and maintenance are
calculated from the financial cost estimates on the following basis:
(i) Price contingencies are excluded but physical contingencies are included because they represent real consumption of resources;
(ii) Import duties and taxes are excluded because they represent transfer payments;1
(iii) The existence of unemployment and under-employment for unskilled workers within the Indian economy means that the opportunity cost of unskilled labour can be considered to be lower than its wage rate – a conversion factor of 0.75 of the market wage rate is used to estimate the shadow wage rate;1
(iv) The market wage rate for skilled labour and the acquisition cost of land are considered to represent opportunity costs, as both factors are in demand;
All costs are valued using the domestic price numeraire, to enable an easier comparison with the information used to measure benefits (e.g. a significant component of benefit is the savings in resources, which would be used in the without project situation).

Sensitivity Analysis. Sensitivity analysis was undertaken in order to test the
robustness of the economic results.
The following changes in parameters and assumptions were analyzed:
• A capital cost overrun of 20 percent;
• Increase in O&M cost by 20 percent;
• Decrease in all project benefits by 20 percent;
• One year delay in implementation; and
• Worst case scenario of combined effect with cost (capital and O&M)
increase by 20 percent; all benefit decrease by 20 percent and one year

5.2 Financial Analysis The financial analysis of the sample subprojects is on an approach governed by
the fact that, firstly, user charges are not very widespread in the state and the
system of property tax does not exist. For the delivery of public services, the
departments and ULBs primarily depend on government subsidies. In this regard,
any upward tariff revision would mean resistance from the users. Secondly, the
Government of Jammu and Kashmir will receive 90% of ADB’s assistance as a
grant and 10% as a loan. Therefore, the weighted cost of capital will not be of
relevance for cost recovery/ remunerative projects. In this regard, cost recovery/
revenue generating subprojects need to be financially viable against a benchmark
cost of capital. Currently, there exists no comparative rate/ tenor combination as
offered by ADB, and the closest market rate for medium tenor funds (10-15
years) is around 9%. The current rate of inflation is in the region of 5%, implying
a required benchmark FIRR of 4% for such projects. In principle, each sub-
project is expected to aim for a FIRR of 4%. The financial analysis for Jammu
Sewer has been carried out on the cash flow. Jammu Sewer is a green field
project
The lessons from the sub project analysis forms the basic principles of financial
appraisal of using balance sheet based financial analysis for service projects with
no cash streams and for cost recovery/ remunerative on the financial returns at
a rate not les than benchmark IRR of 4%. The general principles of engagement
on a sub project are that:
• It should be part of the Sector Master Plan/ Town Development Plan;
• Commitment to conduct an audit of existing situation;
• Development of a business plan by the service provider, addressing costs,
revenues, assets, demand assessment, investment needs and tariff
adjustments over a Seven-year time horizon. The business plan should
• include measurable indicators of performance to be updated and approved
• by the ULB council annually;
JnNURM - Rapid Training Programme Preparation of DPRs
CEPT, Ahmedabad 46
Module 2.6: Engineering Economics
• Improvements in financial management, particularly billing and collection,
and
• Tariffs set at a level sufficient to cover O&M costs during the implementation
period.
• Based on the above assumption of a minimum return of 4%, of Alternative
non-volumetric user charges and property based taxes2 have been worked
out for the sample subprojects. These alternative scenarios have been
compared with the current charges, and the most reasonable structure from
The property tax assumptions are as follows:
Jammu
Population 2001 559000
Households 111800
Households < ARV of 500 30 % 33540
Taxable Household 78260
Taxable Commercial as % of Residential Properties 25
Total Taxable Properties 97825
2 For each sub project three basic charging options were considered.
User charge based recovery of O&M
A combination of upfront connection deposit and a monthly user charge
A combination of a water/ drainage tax as part of property tax and a monthly user charge
Option 3 has been recommended as this is the most doable option.

various alternatives is proposed. The proposed structure also incorporates
reasonable revisions in user charges, fees etc. over the projects’
implementation period.
• Currently the local bodies do not levy property based taxes and the user
charge is the only source for supporting operation and maintenance. In the
absence of database on properties in the city, the average (Annual) rental
value (ARV) of cities of comparable size and economic characteristics has
been used. The user charges have been frozen at a level when the rate of
return is around 4 %, and the most possible option has been selected based
on the reasonableness of the levy. The assumption common for all options
are:
• a 10% increase in capital cost;
• the revision of tax base and user charges at least every five years;
• collection performance for property tax at 80% of current demand
and 50% against arrear demand, and
• that 30% of the household will not be part of the property tax net
due to possible lower rental values.
Based on the analysis as outlined above, the proposed rates are as given in table

there are no

However, even if these charges and taxes are proposed to be implemented in
2010-11, FIRR will not be 4% unless:
• The collection efficiency touches over 80%;
• revisions undertaken every five years if not annually to charges, and
• increasing the consumer coverage substantially
Other actions required will also be in the form of generating public awareness,
enumeration of consumers, creation of a property registry, computerization etc.
The proposed user charges/ taxes based on the required rate of return may
appear to be not feasible at this juncture as the concept of levy of user charges is
recent. GoJ&K may decide to impose lower charges and taxes initially but in such
a situation incremental revisions ought to be steeper than as assumed to ensure
a 4% FIRR over the life of the project. In such a situation, the practical strategy
JnNURM - Rapid Training Programme Preparation of DPRs
CEPT, Ahmedabad 48
Module 2.6: Engineering Economics
is in terms of incremental improvement in recovery of O&M cost by improving
coverage of households, appropriate increases in current user charges, improving
billing and collections and reduction of physical losses. The target should be to
cover 100% of O&M cost by the end of the project implementation period. A
proposal for feasible user charges and taxes for two sample subprojects that
could be imposed to cover 50% and 60% of O& M costs in 2010-11 is presented
in (Table 5.5).

Various scenarios developed in this regard reflect the possibility of improving
performance through basic management measures both on supply and revenue
side.3 However, as with the improvements in electricity supply service in the

the proposed project would be necessary. Table 5.6: Results of the analysis
