The 21 hectare project site is located on the south coast between the suburbs of Thirroul and Bulli. Being previously a brick foundry and clay/shale quarry, Stockland Developments purchased the site for the purpose of developing it into a residential subdivision comprising approximately 200 lots.
The scope of work for this project included the following.
- 560,000m3 of bulk earthworks.
- Remediation of 260,000m3 of uncontrolled fill to a depth of up to 8m.
- Re-alignment and restoration of two live creeks.
- Asbestos remediation.
- Acid soil remediation.
- Design and construction of two bridges.
- Design and construction of retaining/acoustic walls.
- Stormwater pit and pipe installation works.
- Flexible pavement works including sub-base, base course, spray seal and asphalt.
- Services reticulation including electrical, lighting, gas, communications, sewer, recycled and potable water.
- Landscaping and creek regeneration.
Notable outcomes of this project were as follows.
- Developed an integrated retaining/acoustic wall solution along the existing rail corridor resulting in cost and space savings.
- Acoustic walls constructed with no disruption to RailCorp assets or services.
- An asbestos remediation strategy was developed that reduced offsite disposal costs by over $15 million.
- Maintained a high level of environmental compliance during creek works through the construction of diversions and armour rock levies.
- Successfully managed sensitive Aboriginal heritage issues through regular consultation with the community.
