Aura Trunk Services
Scope of Works
Since 2015, Shadforth has been a trusted delivery partner for Stockland’s Aura masterplanned community, delivering critical trunk infrastructure that underpins one of Australia’s most significant and sustainable new communities. Our scope has included sewer, water, and stormwater networks, delivered through a combination of open-cut trenching, tunnel boring, caisson construction, and HDD installations.
Key Achievements Included:
Delivered 14km of trunk sewer infrastructure with pipe diameters up to 1200mm and installation depths reaching 11.5m.
Constructed sewer pump stations up to 5.3m diameter and 12.3m deep, including 1km of 355mm HDD rising main beneath Bells Creek and a 1.7km, 450mm rising main with bridge crossing.
Installed 4km of trunk water mains up to 800mm diameter, incorporating large custom valve structures and arrangements.
Delivered over 20km of trunk stormwater infrastructure and more than 4km of RCBC installations up to 3600x2700 in size.
Installed over 100 manholes, 70 custom stormwater structures, and more than 750 lintels and field inlets across the development.
Implemented horizontal and wellpoint dewatering strategies to manage deep groundwater conditions, including a Queensland-first horizontal dewatering initiative at Aura.
Challenges and Innovations
Shadforth has been instrumental in introducing alternative materials and methodologies that has allowed the Aura masterplanned community development to be recognised by the Green Building Council of Australia as Australia’s most sustainable greenfield master planned community.
One of our key innovations was the adoption of smart pits as an alternative to traditional Type G concreted manholes, offering enhanced durability and efficiency. Our successful development and trial of PE-lined upstands at Aura led to industry-wide IPAM approval, making it a valuable addition to infrastructure projects.
Through close collaboration with Stockland and consultants, we have identified and implemented various design optimisations, such as upper-level sewer, manhole to bends, and material substitutions like manholes to maintenance shafts, and PE water to PVC water, which have resulted in significant cost savings and installation efficiencies. Our work with manufacturers has also led to the availability of PN20 water main pipes as a viable alternative to DICL pipes, eliminating delays caused by material shortages and reducing costs for Stockland. Furthermore, our commitment to sustainability is demonstrated by the introduction of PVC and PE recycling bins at Aura, reinforcing responsible waste management practices.
We have also successfully addressed logistical and supply chain challenges by collaborating with suppliers to introduce alternate material types for water main pipes, eliminating delays caused by DICL pipe shortages. Additionally, through rigorous design reviews conducted in partnership with Stockland, we have optimised installation methods and material selections, leading to significant cost and time savings.
