Coal-tar pitch build up in pipes;

 A significant portion of the structure was raised;

 Soil remediation surrounding foundations; and

 Proximity to Warf

With measures put in place to prevent any environmental impact from the remaining contents of the pipes, work then began on ground level pipes using Major Projects Groups’ LH-30 excavator. Once the raised pipes were disconnected, a large 300 tonne crane was used to lift key sections of gantry onto the ground.

With the transfer tower itself disconnected from the rest of the gantry, it could be brought down. The induced collapse of the tower involved cutting the legs in strategic places and pulling the structure with an excavator. The tower shifted to the north, but remained facing upright to minimise damage to the upper part of the structure and impact to the surrounding area.

The final stage of the demolition process involved falling the remaining raised gantry onto the ground. The remaining scrap steel was then loaded into trucks and removed from the site to be recycled. Before the end of June, all structures and material had been removed.

During the month of July, Major Projects Group completed all remediation works. Using hammer/ripper attachments on excavators, operators hammered out foundations to 400mm below existing surface level and filled the void with slag subgrade and crushed concrete and topped it up with a two-coat seal.
