Construction of a large scale water source
expansion project is always exposed to
some construction risks that can lead
to delay and cost overruns. Commonly
encountered risks and uncertainties
include floods during construction,
foundation conditions, variations
in construction materials, weather
conditions, environmental impacts etc.
Risk management decisions made during
the construction stage must evaluate the
effects of the actions taken to mitigate
the risks. Whatever is done to a dam
during construction will have an impact on
its future performance.
Thi s ar t icle de scribe s t he ri sk
management plan (RMP) formulated for
the implementation of a major water
source expansion project. The framework
of the RMP and the related issues in its
implementation are presented.

he Expansion of Mengkuang Dam Project
with a construction contract value of RM 607
million was awarded by KeTTHA (Ministry of
Energy, Green Technology and Water) to China
International Water & Electric Corp (M) Sdn Bhd
in 2012. This major water source augmentation
project increased the reservoir active storage
from 22 to 73.5 million cubic metres (MCM) and
the raw water supply capacity from 350 to 650
millions of litres per day (Mld). The water source is
vital for the Sg. Dua Water Treatment Plant which
provides over 80% of the potable water supply to
the Penang state. The project is located in the
State near Bukit Mertajam as shown in Figure 1.
