3. The Importance of Financial Management in construction projects
Up to date financial records
Monitor your financial position
-Plan your expenditure to be match with
the income; plan the sources of finance
Credit Control
-checking the money status
Knowing day-to day costs
-operational costs
Have a business plan
- cash flow (money in and out)
-Where your money will need to be targeted
-How much emergency fund the company
will be required

4. Cost Control Techniques
Five (5) important methods used for Cost Control Techniques for Construction Projects.
• WBS: is an organised structure that illustrates the scope of work into manageable concepts. Can illustrate
graphically in boxes, text indents, coding, insert some details such as the floor levels
• Method Statement: is a description of how work will be carried out safely by providing information on how
the work to be done. These include: coding, methodology, quantity of work, machinery, manpower and
duration
• Bar Chart: To plan and control documents for communicating schedule information using Project Management
Software
• CPM: Critical path methods
• Cash Flow Diagram:Used to visualize the project progress over time which include of projected expenditure,
actual expenditure and project income

9. Cash Flow-Inflows and outflows

10. Cash Flow Diagram
• The cash flow statement is a document which models the flow of money in
(positive cash Flow) and money out (negative cash flow)
• A graph of cost expenditure V time is needed to derived the cash out and cash in
for the project. The S curve is drawn to represent the plan cost incurred in doing
the project
• A stepped line is plotted against the S curve represent the forecast of the money
that the contractor will be received. In some cases the client will retain a
percentage of the payment.
• The stepped line will cross the S curve and this will indicate the anticipated margin

11. S-curve

12. S -curve
• An S-curve is the piecewise continuous graph showing the accumulated
expenditure of completed construction work of a project against its duration
from start-up to completion.
• The S-curve is considered simultaneously with a step function cumulative curve
representing the interim payments received by the contractor from the owner
according to project progress
• By combining the cost (contractor's expenses) and value (owner's payments)
profiles, having made the necessary adjustments for retention and payment
delays, one can derive the net cash-flow project profile.
• By that, the maximum working capital required by the contractor for the project
and the cost of its lock-up working capital; i.e. the amount of interest charged
to the contractor due to the execution of the project, if the lock-up working
capital is financed by a lending institution

Projected Expenditure
- Projected expenditure is an
anticipated expenses prior to
sales product in due time.
Actual Expenditure
- Results when money is actually
spent on the various supplies,
services and other expense
categories used by the business.
Income
- The revenues allocated
to projects for a given time
period (i.e., payment by client).
Break-even

14. Financial issues in most construction projects
• Contractors incur costs as the construction progresses. As such, contractors have to meet the
ongoing weekly payroll and monthly material payment obligations while waiting for owners'
discrete payments. The gap (capital lock up)between cumulative expenses and actual payments
received needs to be financed.
• `Financial management', plays the most important role in cash-flow forecasting and that special
caution must be taken in anticipating the occurrence of the following project factors:
change of progress;
payment duration;
project delay;
improper planning;
inability to manage change orders;
number of claims.
These factors contributed very high percentages on cash-flow risk compared with the other
factors

15. Improving Project cash Flow
Several financial manipulations that may improve contractors' project cash-flow/
working capital.
• `Front-end rate loading' is the practice of increasing the rates for items of the
construction work that take place early in the project. This keeps the overall
cost of the work the same but has the effect of increasing the level of payments
early in the project and reducing borrowing costs.
• Advance payment at project initiation as a percentage of the total contract sum.
This payment is then subtracted from the interim payments to the contractor.
• A possible reduction in the retainage percentage, if accepted by the owner, will
have a positive effect on contractor's cash-flow/working capital needs.

16. Normal Vs Non-normal cash Flow
• Normal cash flow project:
- Cost negative follow by a series of positive cash inflow
- One change of sign

17. Non-normal cash flow project
• Two or more changes of sign
• Example mining project

18. Capital Expenditure: Importance
• Importance: stems from 3 inter-related reasons:
Long term
Effects
• Current capital expenditure
provide framework for future
activities
Irreversibility
• Reversal of decision on capital
expenditure may occur a substantial
loss
• No wrong judgment on capital
expenditure
Substantial
capital outlay
• Usually involve substantial capital
outlays.

19. Capital Budgeting
• Therefore, capital budgeting is a systematic approach to
determining whether a company’s planned major capital
investments are worth pursuing.
• Capital budgeting is concerned with the justification of capital
expenditures. It can provide a rationale to select between
alternative projects:
• The QUESTION IS………….Which proposed project will most
increase the company’s value over time?

22. Time value of money
• Money has time value. A dollar received today has a greater value
than a dollar received at some future time .
• Time value of money is the idea that money available at present time
is worth more than the same amount in the future, due to its potential
earning capacity.
• When money is borrowed, the interest paid is charge to the
borrower. Interest compensates the depositor/lender for the time
value of money.

23. Time value of money (cont..)
• Therefore when deciding among alternative projects to invest, we
must take into account the operation of interest and the time value of
money.
• For example investors are willing to forgo spending their money now
if they expect a favorable return on their investment in the future

25. Cash Flow diagram
• Cash flow diagrams are visual representations of cash inflows and outflows along
a time line.
• They are used to detect which of the five patterns of cash flow is represented by
a particular problem.
• The cash flow patterns are significant because they allow us to develop interest
formulas. The five patterns of a cash flow are:

26. Cash Flow diagram
• Eg. A company plans to invest RM 500,000 (p) (downward-pointing arrow) to manufacture a new product. The sale of this
product is expected to provide a net income of RM 70,000 (upward pointing arrow) a year for 5 years , beginning at the
end of the first year

27. • Single payment: Present worth; future worth
• Equal payment series: Future worth; present worth factor; sinking fund;
capital recovery
• Linear gradient: gradient present worth; gradient equal payment
• Geometric pattern series: present worth
• Uneven series: A series of cash flows exhibiting no overall pattern.

installment for 5 equal installment

42. Quiz 15
• If Laurel made a RM 30,000 investment in a friend’s business and
received RM 50,000 five years later, determine the rate of return ,i

43. Net Present Value (NPV )
• The basis of NPV method is that all future payments/receipts are
converted to present value.
• NPV can be used as to determine whether a project is profitable enough to
be considered a worthwhile investment.
• Accept the project if positive NPV, reject if negative NPV
• Project with the highest NPV is the most favorable to invest

44. Internal Rate of Return (IRR)
• The internal rate of return (IRR) of a project is the discount rate
(interest) which makes NPV=0
• The purpose is to differentiate between 2 or more projects in order to
choose the least expensive.
• The IRR sometimes is called as discounted cash flow yield (DCF)
Yield
• IRR is the maximum interest rate that could be paid on borrowed
capital

45. Minimum Attractive Rate of Return (MARR)
• MARR is a reasonable rate of return established for the
evaluation and selection of alternatives.
• A project is not economically viable unless it is expected to
return at least the MARR
• MARR sometimes called as hurdle rate, cutoff rate, benchmark
rate and minimum acceptable rate of return

46. Size of MARR relative to other rate of return values

47. Incremental analysis
• incremental analysis is used to analyze the difference between
the two projects;
• Compute the cash flow for the difference between the projects
by subtracting the cash flow for the lower investment from that
of the higher investment

48. Interest paid & Interest Earned
• Two perspectives of interests are: interest paid and interest earned.
• Interest is paid when a person/organization borrowed money/loan and
repays a larger amount over time
• Interest is earned when a person/organization saved/invested/or lent
money and obtains a return of a larger amount over time

49. Example: NPV & IRR
Accept the project if NPV is positive; Reject the project if NPV is negative;
Project with the highest NPV is the most favorable to invest
MARR=10%
Case 1: To find IRR; interpolating between 10% and 20%; IRRA=10%+{10X76700/76700+22100}
IRRA=17.763%; therefore < than 17.63% accept the proposal and > than 17,763% reject the proposal.
Case 2: IRR=33.01%; Less than < 33.01% accept the proposal; > 33.01% reject the proposal

51. Intersection point and Incremental analysis
• When NPV and IRR conflicts with each other, solve the problem:
a) determining the intersection (fisher’s) (using graph paper). An
intersection between the slopes of the cash flow profiles is called Fisher’s
intersection- after the economist Irving Fisher.
b) incremental analysis is used to analyze the difference between the
two projects; Compute the cash flow for the difference between the
projects by subtracting the cash flow for the lower investment from that
of the higher investment;
c) Solve the problem by MIRR (Modified Internal Rate of Return)

55. Comments-NPV
• NPV is absolute measure. It is dependent on the size of the
contribution of the project to the wealth of the company.
Projects that maximizes the total NPV will maximize the total
value of a company.
• The main difficulty is the choice of discount rate.
• The discount rate on the curve where the NPV changes from
positive to negative represents IRR.
• IRR/DCF yield is the max interest rate that could be paid on
borrowed capital.

56. Comments on IRR
• IRR is the value of the discount rate at which NPV=0
• IRR is a relative measure, it does not depend upon the size
of the project or the investment.
