Construction of a new 1.5ha composite lined landfill cell including:

• bulk earthworks
• GCL and HDPE liners
• HDPE pipelines
• drainage aggregate placement with filter geotextile covering

Following on from the success of the cell construction Goldsmith was also awarded construction of a new leachate pond as a variation to the contract.

Construction of the final 2ha landfill cell for Transpacific’s Fraser Road site, including:

• bulk excavation to subgrade
• construction of clay liner
• HDPE and cushion geotextile installation and placement of leachate aggregate

The key challenge overcome on this project depended on Goldsmith’s ability to construct the cell in a deep excavation 3m below ground water level and surrounded by existing waste on all sides.

Construction of a new 1ha composite lined landfill cell including:

• 200,000m3 bulk earthworks
• GCL and HDPE liners
• HDPE pipelines, drainage aggregate placement with filter geotextile covering

Location: Drysdale, VIC
Client: City of Greater Geelong
Start: December 2014

Value: $4.3m

This project required construction of the new 4.5ha composite lined landfill cell 6 and included:

• 24,000m3 of subgrade earthworks
• construction of 500mm thick clay liner
• GCL, HDPE and cushion geotextile supply and installation
• 1.7km of HDPE leachate collection pipelines
• 300 thick aggregate layer
• installation of the separation geotextile layer

Works in Cell 4a included constructing 10 stages of clay separation bund as well as the final stage of clay liner of the southern batter.

Value: $7.7m

Construction of these two large landfill cells included:

• 116,000m3 of subgrade cut to fill
• 78,000m3 of clay liner
• 14.4ha of GCL, HDPE and cushion geotextile installation
• 3.3 ha of geogrid reinforced 300mm crushed rock layer
• 9km of DN110 and DN160 HDPE leachate collection pipes
• 33,000m3 of leachate drainage aggregate
• 11ha of separation geotextile installation

A key feature of this project was Goldsmith’s ability to work though landfill gas issues when piggy back lining the 3.3ha batter over old waste, by developing safe systems of work to enable successful project completion.

This project involved the construction of a new 10ha composite lined landfill cell, including:

• 88,000m3 of subgrade earthworks
• 104,000m3 of clay liner construction
• GCL installation in the base of sumps
• 10ha of HDPE liner and cushion geotextile
• 6.6km HDPE pipelines
• 29,000m3 of leachate drainage aggregate placement
• 10ha of filter geotextile installation

A key to Goldsmith’s success on this project was our ability to produce complying subgrade and clay soils from existing materials on site and in the neighbouring Holcim quarry.

This project involved extending the current active landfill cell to create additional landfill airspace. Construction of the 1.3ha cell extension included:

• a 500mm thick clay liner
• HDPE liner
• cushion geotextile and leachate collection system including DN160 HDPE pipes
• 300mm thick aggregate layer and separation geotextile

Goldsmith was engaged under emergency conditions to assist with the clean-up of Parkwood Recycling Estate (Skippy Bins), following an uncontrolled fire within the stockpiled waste material. Acting on very short notice, Goldsmith provided heavy equipment, operators, supervision and engineering support 24 hours per day, 7 days per week, to assist the fire department and other contractors to put out the fire in waste material. Goldsmith then relocated the material to the neighbouring West Belconnen Resource Management Centre, where our equipment spread and soaked the material, before relocating and placing it in its final location within the landfill cell.

Building on the success of Goldsmith’s previous engagement at West Belconnen, Goldsmith secured the current operations 3 year contract. The focus of the works includes acceptance of asbestos contaminated demolition waste along with other clean fill and asbestos contaminated material.

Since its reappointment, Goldsmith has also constructed new landfill cells on the site to ensure the ongoing acceptance of demolition waste.
