Scope of Works
- Installation of a capping layer over the existing land
- Demolition and removal of existing jetties and structures, existing wharf structures and disconnection and removal of existing electrical services
- Supply and installation of sheet pile walls shoring at the northern and southern extent of the project ensuring that the existing heritage wall is supported and remains intact and that disturbance to adjacent sensitive receptors is managed and in accordance with the project conditions
- Excavation and dredging of 3,500m3 of in situ material and transport offshore for disposal

Challenges
- Due to proximity to sensitive receptors, challenges were found in complying with the conditions of the development application and the review of environmental factors with respect to noise and vibration restrictions
- Compliance with the sea dumping permit for the offshore disposal of dredged material
- Coordinating on water access with Harbour Master
- Installation of sheet pile wall shoring with suitably sized equipment to ensure that the existing heritage wall remains intact
