Project Details

This project featured the construction of a 30 megalitre post-tensioned concrete reservoir to service the Gold Coast Desalination Plant mixing and storage requirements as an essential part of the South-East Queensland (SEQ) water grid.

This reservoir was a critical component of the SEQ water grid roll out, requiring tight management of the construction program to ensure delivery on time. Thorough planning and strict control of all activities on site, resulted in Alder Constructions completing the project ahead of schedule, despite delays due to inclement weather.

The 3000 m² post tensioned concrete slab was constructed in a single pour requiring 30 concreters to complete

350 tonnes of reinforcement and 100 kilometres of steel tendons.
90 tonnes of structural steel and metal sheet roofing that completely enclosed the tank.
Ancillary metal works, including davit arm, ladders, platforms and handrails.
