McConnell Dowell is pleased to announce the early completion of the Waste Line Replacement Project for Queensland Alumina (QAL) in Gladstone, Queensland. After signing the contract in June 2020, the company’s market leading pipeline and marine construction expertise provided a strong foundation for the project’s success.
The Waste line Replacement Project involved the:
- Design of the new Waste Line 4 and the augmentation design of the support structure
- Removal of the existing DN350 WL4 pipeline
- Augmentation of the support structures, including approximately 1400 piles within tidal and marine zones
- Installation of the new above ground waste piepline - 8.8 km of DN 350 SCH 60 steel pipe.
Over 150,000 hours were worked on site with zero lost time injuries and no environmental incidents recorded. The team’s strong focus on quality was also evident with zero weld repairs recorded. The project contributed to the economic well-being of the region through maximum use of local industry.
This important new asset will help protect the local waterways and environment around Gladstone.
