CHURCHILL PUMP STATION DECONSTRUCTION PROJECT - WAIKATO
PROJECT OVERVIEW
The deconstruction of the Churchill Pump Station Waikato was a landmark project characterised by its complexity and scale. This initiative involved the complete dismantling of a heavily reinforced concrete dam, a feat that required meticulous planning and execution. The project encompassed the full removal and disposal of debris, which was transported to Nikau’s dedicated recycling facility in Meremere. Chosen by the Waitako District Council, Nikau was tasked with delivering a solution that not only adhered to stringent economic and environmental criteria but also met precise timelines.
NIKAU’S PROJECT APPROACH AND SOLUTIONS
Nikau's strategy for the Churchill Pump Station Waikato deconstruction project was anchored in rigorous project management and a strong dedication to environmental stewardship. Our approach involved several key components:
1. Sediment Control Measures:
- Implementation: We established extensive sediment control protocols to manage and mitigate the runoff of concrete slurry and other demolition by-products.
- Impact: These measures were crucial in safeguarding the surrounding natural environment from potential contamination, thereby adhering to regulatory and environmental standards.
2. Demolition and Recycling Operations:
- Concrete Cutting: Our specialised concrete cutting team employed wire saws to meticulously cut 10-tonne sections of the dam. These sections were then safely lifted and removed using a 250-tonne mobile crane, ensuring precise and controlled dismantling.
- Concrete Recycling: More than 800 tonnes of concrete were processed and crushed at our recycling facility. This recycled material was repurposed for future construction projects, thus supporting the circular economy and reducing waste.
- Steel and Metal Recycling: Over 200 tonnes of steel were recovered from the dam structure. This steel was sorted, processed, and recycled, reflecting our commitment to maximizing resource efficiency and minimising environmental impact.
CONTRACTOR RESPONSIBILITIES
Nikau’s role encompassed several critical responsibilities, showcasing our expertise and adherence to high standards:
1. Sediment and Erosion Control:
- Installation and Management: We installed robust sediment and erosion control systems to effectively manage environmental impact and prevent contamination of the site.
- Compliance: These controls were in line with environmental regulations and best practices, ensuring the project’s minimal ecological footprint.
2. Concrete and Steel Recycling:
- Concrete: We successfully processed and recycled over 800 tonnes of concrete, facilitating its reuse and reducing reliance on new raw materials.
- Steel: The recovery and recycling of more than 200 tonnes of steel underscored our dedication to resource efficiency and sustainability.
CONCLUSION
Nikau’s comprehensive approach to the Churchill Pump Station Waikato deconstruction project ensured the highest standards of safety, efficiency, and environmental responsibility. Our meticulous planning and execution reflected our commitment to both project success and sustainability.
