The redevelopment of this site will create 30 residential lots and 7 multi-dwellings site of approx. 350 apartments. The civil works included demolition, remediation and relocation of major services.

Key Considerations

  • Undertaking major servicing investigations and costs in relation to relocation of major water and sewer services within the site.
  • Undertaking engineering investigations and providing a report and costs on designs.
  • Partaking in design workshops with the project team and providing valuable engineering advice.
  • Reviewing environmental and geotechnical reports and incorporating findings into engineering reports.
  • Coordination and management of Environmental and Geotechnical investigations for the site.

Project Challenges

Site Remediation and Demolition

As the site was used as an old nursery there were a several sources of contamination to consider. To ensure the subdivision works could proceed without unhindered, JDSi recommended a forward works stage which included clearing, demolition, remediation, service relocations and preparation of tree transplants to de-constrain the site.

Infrastructure

The project required relocation of major infrastructure to de-constrain the site and enable effective planning outcomes. Relocation of the existing DN535 water main enabled larger multi-dwelling sites adjacent to Salvado Road, however investigations to relocate the DN2100 sewer main were cost prohibitive and therefore this area was developed as high amenity POS.

Bulk Earthworks Strategy

The Bulk Earthworks strategy for the site was to ensure a cut to fill balance whilst creating single residential lot and multi-dwelling lots with basements. To maintain flexibility during construction the multi-dwelling sites where only excavated as required to ensure no import fill or exporting of clean material was needed.

Stormwater Management

Due to the site being adjacent to a conservation category wetland and Environmental Projection Policy Lake (Mabel Talbot Lake), management of the 100 year ARI was required within the site. JDSi designed the stormwater system in accordance with the approved UWMP requirements which included rain gardens, underground storage and soakwells. There were a number of factors to be considered including groundwater levels, retention of significant trees, high amenity landscape, parking embayments and lot access.
