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.
