RISK FACTORS AND MANAGEMENT IN
CABLE STAYED BRIDGE CONSTRUCTION PROJECT – A CASE STUDY OF NHAT TAN BRIDGE
PROJECT IN HANOI
By
Nguyen Ninh Son
Abstract
In
bridge construction projects, even minor problems in any work at any time may
cause serious un-expected consequences. Risk management will reduce and prevent
risks happen to the project. In risk management, we need to analyze risks
firstly. Risk analysis will help to identify potential risks can be happened to
the project, therefore we can restrain risks and maximize reduce damages of the
project.
This
Study mentions about subject: Risk management in bridge construction project in
Vietnam in general and Nhat Tan bridge construction project in particular.
Through this Study, I hope that I can present to Engineers, Managers a overall
view of risks prevention in construction and operation stage of bridge
construction project.
This
Study carry-out risks analysis in Nhat Tan bridge construction project base on
my own experiences and knowledge studied at AIT. Through this Study I hope that
I can present a risk management framework for bridge construction projects.
Executive summary
Rationale of research
This research has been conducted to identify the risk factors in
Bridge construction projects.
Objectives of study
To identify factors of risks
management of constructions project in general and bridge construction project
in particular, with focus on “Risks Factors and Management in Stay Cable Bridge
Construction Project” and apply in Nhat Tan cable stayed bridge construction
project.
Face to
potential risks and what managers should do to minimize the defects and
predict, prevent other risks occur?
Methodology
The exploratory research method is used for literature review,
to study and analyze Risks Factors
and Management in Stay Cable Bridge Construction Project.
Findings and conclusion
The purpose of project risk management is to reduce
the risk in order to achieve the objective of the project such as time, cost,
quality, safety and environment. In particular, risk management helps people
involved as project manager, HSE manager, and quality manager, in setting
priorities, allocating resources and implementing actions and process to
mitigate the risk of the project.
Construction is performed by Contractor to ensure
that the work is completed successfully. Risk factors in construction stage of
cable stayed bridge construction project often occur in: Health and Safety,
Environment, Cost and Technical problems. Main risks included:
·
Delay of land acquisition, seriously affect to
cost and schedule of the project.
·
Low quality of input materials: sand,
aggregate, cement, steel (for fabrication of main girders), cable do not
satisfy requirements of specification.
·
Method statements are not suitable with site
condition and not effective.
·
Lack of supervisor, instruction of Consultant
Engineer in working process.
·
Dangerous working conditions: working in the
large river, working at height.
This research also has conducted
a risk management study for cable stayed bridge construction project. The case
study in this research is the real cable stayed construction project. Some of
solutions given in this research have applied in the real conditions of the
project. They worked effectively and also reduce bad effects, damages of the
project caused by risks.
