  1. MELBOURNE DOCKLANDS PRECINCT DEVELOPMENT & THE FORMER WEST MELBOURNE GASWORKS REMEDIATION PROJECT Andrew Labbett – Associate Remediation Engineer

  2. Presentation Outline • Melbourne Docklands - proximity/size • History of the Melbourne Docklands Area • The Docklands Authority • The Former West Melbourne Gasworks Remediation Project • What it was • What we found • What we did • The visions being realised…

  3. Melbourne Docklands Precinct • Central Business District • Melbourne Docklands

  4. Melbourne’s West – 1864

  5. Melbourne’s West – 1858

  6. West Melbourne Gasworks – 1928

  7. West Melbourne Gasworks – 1937 Contaminant Sources • Wharf/ Coal Loading Area • Coal Stores • Retorts • Purifiers • Sulphate & Ammonia Plant • Gasholders • Tar Pits & Tanks • Plant Upgrades

  8. Dereliction of The Wharfs, Railyards & Gasworks • Ship freight became more containerised – hence bigger, open yards and deeper docks required (Appleton, Webb and Swanston Docks). • Charles Grimes Bridge pushed larger ship docking sites westwards. • Modern day transport methods (air & truck) made large shunting yards redundant. • Discovery & use of natural gas from Bass Strait saw gasworks closed in 1970. • Derelict waterfront area now ripe for “reconnection” with the city.

  9. West Melbourne Gasworks & Docklands – 1989

  10. West Melbourne Gasworks & Docklands – 1989

  11. Docklands Authority

  12. Melbourne Docklands Development Precincts

  13. Wooden Piles…

  14. Coal Tar…

  15. Soil Treatment Processes

  16. Waste Minimisation – Soil Screening

  17. Waste Minimisation – Concrete Recycling

  18. Waste Minimisation – Soil Treatment

  19. Remediation Works

  20. Remediation Project Statistics • 7.6 hectare site • 273,000 m3 material excavated (1.0 – 8.3 m below original grade) • 4100 Wooden Piles & 460 Steel Encased Concrete Piles • 1700 stockpiles • 50,000 truck movements • 35% of excavated material recycled • 69,000 m3 of intra-precinct material imported and used as fill • Over 300,000 tonnes of ‘Contaminated Soil’ to landfill • 40,000,000 litres water treated and disposed (some for dust) • 500 site inductees • $45 M plus for level site.

  21. Victoria Harbour Precinct - 2009

  22. Victoria Harbour Precinct – 2009 (N – S)

  23. Victoria Harbour Precinct – 2009 (W – NE)

  24. Victoria Harbour Precinct – 2009 (S – NW)

  25. Victoria Harbour Precinct – 2009 (S – N)

  26. Victoria Harbour Precinct – 2009 (Mid – S)

  27. Summary of Whole-Precinct Development Benefits • Ability to optimise best sites for purpose (i.e. ensure correct mix of open space, residential, commercial) based on levels of contamination. • “Over-kill” remediation – i.e. sustainability considerations can be made. • Odours, dust & other construction emissions have less impact. • Materials and treatment-space sharing (when appropriate). • Services sharing/ staged development.

  28. Thank You!
