Redbank Motorway Estate Stormwater Works
DN3000 Pipes Support High-Capacity Drainage for Major Industrial Development
Background
Delivering High-Capacity Stormwater Infrastructure for a Large Industrial Estate
Redbank Motorway Estate is a large logistics and manufacturing development spanning more than 100 hectares along the Brisbane River, approximately 20km south-west of the Brisbane CBD. The scale of the development and extensive hardstand areas required robust stormwater infrastructure capable of managing significant runoff during major Queensland storm events.
The Challenge
Managing Large Stormwater Flows in a Challenging Site Environment
Construction of lead-in infrastructure for the estate included new and upgraded external roads, along with major sewer and stormwater works. The stormwater system needed to accommodate very high flow volumes, while also addressing challenging site conditions, including steep grades, aggressive soils and direct discharge into the tidal Brisbane River.
Durability and long-term performance were critical requirements for the stormwater pipeline.
The Solution
Supplying Large-Diameter Concrete Pipes with Enhanced Durability
Shadforth engaged Humes to supply large-diameter steel reinforced concrete pipes capable of handling the required stormwater flows. Humes manufactured and supplied more than 200 metres of DN3000 stormwater pipes, including units with freshwater cover and salt water cover to suit varying exposure conditions across the site.
The pipes were designed to deliver a 100-year design life, providing confidence in long-term performance for this major industrial development.
Outcome
Efficient Installation and Reliable Performance Delivered to Program
Through close coordination with the contractor, Humes supplied the pipes in line with the construction program, supporting efficient installation of up to 16 pipes per day. The stormwater works progressed smoothly, allowing key project milestones to be met while delivering a high-capacity drainage solution suited to the scale and demands of the development.
