Liberty Industrial was engaged to carry out the dismantling and removal of the B48 Liquor Burning Stack at Alcoa’s facility in Wagerup, Western Australia. The project involved the stabilisation of the dilapidated stack and staged dismantling using two large hydraulic cranes.
- A massive 500t hydraulic crane with 60 meters of main boom and 91 meters of fly was utilised to remove the stack sections.
- A 250t crane was used to gain access.
- Our team undertook structural assessment and monitoring to assess the environmental performance and structural integrity of the shortened stack after the removal of the first piece.
- Extensive stage planning was undertaken to ensure that there were no collisions between the two cranes.
Our team engineered a solution to maintain stack stability at all times during the dismantling process and completed the project without any incident. Our safe, reliable and affordable solution allowed the project to be completed on schedule despite various challenges.
