Risk Management Group and their Task:

During construction stages of suspension bridge there may be several risk factors, so to mitigate these construction risks, a risk management group of six members with extensive experience in the disciplines of project management was formed ,which is as follows:

Praveenkumar Rajachintala as a Team Leader

Hari boppudi as an Infrastructure Engineer

Ricky Ponting as an Environmental Engineer

Stew Edward as a Risk Manager

Andrew Wallis as a Geo-Technical Engineer

Mitchel Johnson as a Technical and Legal officer

The main task of the risk management group is to set out the key issues and concepts involved in effective risk management in a clear and accessible way. To achieve specific goals and objectives of the project the risk management group has to deal with risk identification, its analysis and evaluation and treatment. Also the task of Risk management group is to monitored risk and effectiveness of control measures to ensure the changing circumstances do not alter risk priorities.

Project Phase:

Due to increase in population of the city as well as suburbs the city council decided to develop the transportation facilities to the people by constructing suspension bridge. The 800 M long bridge links suburbs to the city centre. The construction work is planned to complete within four different phases

Phase I (Preliminary Phase)

Detailed survey of geology and topography of the site

Selection of shortest distance for bridge construction

Phase II (Design Phase)

Analysis of survey data

Moment and Load Considerations in Design (Dead load, live load, wind load and seismic loads)

Design of structural elements (Piers, abutments, pavements etc.)

Phase III (Construction Phase)

Foundation works for piers and abutments

Construction of anchor on each side

Building of bridge towers on concrete footing

Stretching the cable over the towers and setting into anchor on each side

Attaching trusses to the main cable

Phase IV (Completion and Inauguration Phase)

The bridge ready for public use

Risk Identification:

The main aim of risk identification is to identify the risks that may affect the progress of the project. So, it is important to identify and categorize risks that may adversely affect the project. Some of the distinct project risks identified by our team members are listed below

Environmental Risks

Air Quality Deterioration

Disposal of Hazardous waste problem

Problem on disposal of surplus quantity of Earth

Water Quality deterioration

Technical Risks

Incomplete planning and designing

Error on Environmental impact assessment

Unexpected geo-technical issues

Lack of skilled construction personal

Inaccurate contract time estimation

Variation in operation cost

Legal Risks

Problems with local anti development residents

Failure to carry out work in contract time may lead to potential legal liability

Work place health and safety issues

Purpose of the Risk Proposal:

Risk proposal is a document containing evidence of systematic approach to risk identification and analysis. It provides decision makers with a risk management plan, for approval and subsequent implementation of the project. Risks involve both threat and opportunity, organizations which better understands the nature of the risks can manage them more effectively. Ultimately the risk proposal demonstrates the need for changes in project plans and helps decision makers to take necessary actions.

A systematic procedure to identify the risk is not sufficient to find all kind of risks. Approaches used to identify risks must include tools and techniques such as checklists, judgements based on experienced, brainstorming etc. In this project the risks identified by our team is categorized into three types

Environmental Risks

Technical Risks

Legal risks

These risks are analysed to separate the minor acceptable risks from the major risks. We then assign a priority to each risks based on their consequences and likelihood that those consequences may occur. Our team found major risks in technical issues relating to the contract time estimation and the other risks on Environmental and legal issues are analysed as a minor risks and can be accepted after minimal further Treatment. All the risks identified and its treatment is briefly described on Appendix III.

Monitoring and Review:

It is necessary to monitor risks, the effectiveness of risk treatment plan, strategies and the management system. Risks and the effectiveness of control measures need to be monitored to ensure changing circumstances do not alter risk priorities. Ongoing review is essential to ensure that the management plans remains relevant. In any project it is necessary to regularly repeat the risk management cycle.

In this suspension bridge projects monitoring and review of factors which may affect the likelihood and consequences of an outcome, factors which affect the suitability or cost of the various treatment options should be frequently monitored and reviewed.

Conclusion and Recommendation:

In this project most of the risks identified are minor and could be managed by effective risk management technique. So with this project our company could get

more financial benefits as well as goodwill in the public. And also the profile of the company could reach to high standards
