Acid Tank 4 Remediation Project

Project Brief

RMK Civil was engaged by BHP Billiton to complete the Acid Tank 4 Remediation Project at the Olympic Dam site, a key mining operation in Australia. The project required careful planning, technical expertise, and a strong commitment to safety, quality, and efficiency. With a total project value exceeding $10 million, RMK Civil delivered the work on time and to a high standard, restoring critical infrastructure to full functionality.

Solution

RMK Civil applied its expertise across several capabilities, including excavation, steel fixing, formwork, concrete, and civil engineering, to deliver the project. Key activities included:

• Controlled Demolition and Waste Removal: Damaged concrete and contaminated materials were removed in sections to minimise risks to workers and the environment.
• Reinforced, Coated Concrete Installation: High-grade reinforced concrete with protective coatings was installed to ensure long-term durability and resistance to chemical exposure.
• Quality Assurance: Comprehensive testing and inspections were carried out to ensure the repair met industry standards and client expectations.
• Streamlined Project Management: The team managed resources and schedules efficiently, maintaining momentum while upholding strict safety protocols throughout the project.

Outcome

The Acid Tank 4 remediation was successfully completed within the 5-month timeframe, allowing BHP Billiton to resume operations as planned. The reconstructed tank floor met durability and performance specifications, providing a guaranteed minimum lifespan of 20 years.

"Ryan would like to express appreciation for the effort that RMK put into this project. In part due to RMK’s effort, the project overall was executed successfully as planned to achieve a successful return to service for Acid Storage Tank 4."
