BATTERY RECYCLING PLANT
Enviropacific Services Pty Ltd
May 19 – August 19
Industrial Demolition & Deconstruction
Major Projects Group facilitated the demolition of a large battery recycling plant in Alexandria, NSW. The 40-year-old, 1.7-hectare facility had been used for battery breaking, acid neutralisation and component storage. The site consisted of one main building, several smaller, outer buildings and one 46-metre-high stack.
The site being located amidst a highly built-up, commercial suburb, less than 5kms from the Sydney CBD, presented several major challenges, including very strict dust control requirements and limited space.
SCOPE OF WORK
The works onsite included the demolition of several small metal buildings, the large primary structure, the 46-metre-high stack and the removal of all metal and concrete from site. The project took place over the course of three months from May 2019 to August 2019, in Alexandria, NSW.
Limited operating space;
Close proximity to highly populated area;
Hazardous materials on site; and
Tall structure on site.
Once the principle contractor had conducted the strip out and cleaning of the structures onsite, our demolition work began. We used our 30 tonne Liebherr LH-30 excavator to procedurally remove the plant walls and the 4,000 square meters of metal roof sheets.
A second 29-tonne excavator with a hammer attachment was used to demolish the concrete structures on site and leave a clear level. The materials were loaded into trucks and removed from the site to be recycled.
The removal of the 46-meter stack was the next stage in the demolition process. Due to the limited space and proximity of neighbouring buildings, the stack could not be toppled and instead needed to be lifted in sections by a crane. Two large cranes were used to remove the stack in three separate sections, these pieces were then broken down by an excavator.
Throughout the entirety of the demolition process, water suppression was used extensively to minimise dust from the metal and concrete being removed as well as the vehicles mobilising on site. Both a water cannon and mobile water truck were used for this process.
With all of the buildings demolished and material removed, a clear concrete site was left; ready for future development. The project was completed on time, with no incidents and minimal interference to the surrounding buildings.
