A large portion of the Yelgun to Chinderah Freeway was located in areas underlain by soft soils. Construction of the road embankments in these areas presented significant constraints and risks to the project, involving short term instability and long term settlement. Due diligence was carried out to ensure development of effective solutions and control and reduction of risks. A risk management system was implemented integrating design, construction, and field testing and monitoring to achieve the stringent project requirements. The design and construction were constantly reviewed and modified as required in response to the field performance. This process allowed flexibility in design and construction and was proved to be successful and cost effective.
