Abstract- Earned Value Management (EVM) is one of the
best method to track the progress of a construction
project. It takes into account both the time and the cost
factors to evaluate its performance and forecast its
completion time and cost. This paper discusses about how
Earned Value Analysis (EMA) is introduced to a
residential construction project. It calculates the
performance in cost and schedule and pin points areas
where improvements have to be made. It is predicted that
if corrective actions are not made as per the current
situation, the project will get delayed by 17 days and also
that the contractor is estimated to make an additional
profit of over six lakhs than what was originally planned.
Key Words:Earned Value Management, Earned Value
Analysis (EVA)
1. INTRODUCTION
In developing countries like India, the construction industry
faces a lot of project over runs due to the large amount of
uncertainties. These project overruns are primarily
attributed to time and cost overrun [1].
The conventional way of evaluating the budgeted cost is by
analysing the difference between the planned and actual
costs that arises in the project. Earned Value Management
introduces a third variable called Earned Value which would
give a clearer understanding of the budgeted cost and the
schedule. It acts as an early warning to the project manager
to spot and control potential problems that may arise so as
to maximise profits and minimize delays [1] [2].
EVM is regarded as one of the best methods to track the
project progress and its performance. It is said to have
originated from the US Defence Agencies back in the ͳ96Ͳ’s.
EVM is extensively used in the manufacturing industry and
later found its way to the construction industry after it was
standardized by the Project Management Institute. Using
EVM the project manager can assess how ahead or behind
the project and if the project is over budget or under budget
[3].
By using three variables, the planned value, earned value and
the actual cost other variables like schedule variance, cost
variance, schedule performance index, cost performance
index, budget at completion and so on can be computed.
Using these computed variables the performance can be
maintained or improved. It will even give a heads up
concerning the required cash flow for the project, thereby
giving ample time for the clients to raise the money [4].
2. IMPORTANT EARNEDVALUE MANAGEMENT
TERMS
The basic terms associated with Earned Value Management
[1] [2]
Planned Value (PV): It is the amount of money budgeted to
be spent at a particular point of time.
Earned Value (EV): It is the amount of work in terms of cost
that is actually accomplished at a particular point of time
with respect to the planned value.
Actual Cost (AC): It is the actual amount of money spent for
the corresponding planned and earned value.
Cost Variance (CV): It is the difference between Earned
Value and Actual Cost. (EV-AC)
Schedule Variance (SV): It is the difference between Earned
Value and Planned Value. (EV-PV)
Cost Performance Index (CPI): It is the ratio between
Earned Value and Actual cost. If CPI greater than 1 then the
project is under budget and CPI less than 1, then the project
is under budget.
Schedule Performance Index (SPI): It is the ratio between
Earned Value and Planned Value. It indicated how much
ahead or behind schedule the project is at a particular point
of time.
Critical Ratio (CR): It is the product of Cost Performance
Index and Schedule Performance Index. It indicates the
overall performance of the Project with respect to both cost
and time.
Estimate at Completion (EAC): It’s a prediction of the total
project cost based upon the current trends in project
performance.
Variance at Completion (VAC): It is the difference between
the planned budgets at the beginning of the project to the
Estimate at Completion. This value denotes how much more
profit or loss the contractor will make on that Project.
Time Estimate at Completion (EACt): It predicts the
completion time of a Project based on its current
performance. EACt = (BAC / SPI) / (BAC / months)
