The project was to hydraulically place 370,000 m3 of sand to raise the surface level of the Kingscoast Estate by 3 metres. The sand was dredged from an adjacent sand quarry by the Nu Bounty, a 450mm bucketwheel cutter suction dredge in combination with a 500mm, 2,000 hp booster pump. The slurry was pumped distances up to 2,000m through a 560mm poly pipeline to the estate. Considerable savings and advantages were achieved over traditional methods.
It takes time to adapt to new regulations and methodologies; however the Chinderah Bypass contract saw Neumann Contractors placed in a situation that required experience that was yet to be gained. No precedence had been set so a sharp learning curve was essential. The Chinderah Bypass was a technically complex project that required a combination of best management practice and the conception of new industry practises to achieve the desired end.
Neumann’s were awarded the civil works contract, for the Gold Coast Convention and Exhibition Centre project, where the relocation of the major waterway, essential services and environmental issues presented some demanding challenges. This project brought its own unique complexities as it involved several different concurrent tasks.
