Key Challenges and Risks:

• Design finalisation.
• Obtaining statutory authority approvals including Crown certification.
• Conducting the project on a heritage site, requiring careful consideration of preservation measures.
• Working around flora of high heritage significance, which required a high level of environmental sensitivity, extensive protection measures, compliance with regulations and working in partnership with the project arborist.
• Remediation of site contamination including removal of hazardous waste and asbestos.
• Constructing a large retaining wall in close proximity to heritage significant trees, which required careful handling and monitoring to ensure safety and environmental compliance.
• Coordination with adjacent contractors to ensure that none of the works were impeded by each other’s activities, which required effective communication and planning.
• Completing the project in a residential area while ensuring effective stakeholder management both internally and externally.

Project Components:

• Removal of the existing timber boardwalk.
• Installation of new screw piles.
• Construction of a new boardwalk with Fibre-Reinforced Plastic (FRP) materials.
• Intricate design with curved radiuses for custom made balustrades.

Key Challenges and Risks:

• Working in a sensitive environment, which included the flying fox nesting season required careful planning and coordination to minimize any disturbances to the ecosystem.
• Working in a high-water table environment, which required the use of specialised equipment and techniques to prevent any damage to the swamp and its flora.
• Protecting trees and their root systems while screw piling, which required careful monitoring and communication with the client and other stakeholders.
• Designing and constructing curved radiuses for balustrades, which required customised solutions and close attention to detail to ensure compliance with quality, safety and environmental standards.
