Overview
Construction of a new greenfield wastewater treatment plant to provide wastewater treatment services to new development in the Logan region.
Works Undertaken
Construction and commissioning of:
- 1400m3 of concrete structures, including bunded slabs, roadways, tanks, footpaths and pits
- 2800m of chemical, water and sewer pipework ranging in size from DN90 to OD630
- 4m deep DN3000 chemical collection structure, 6m deep DN2400 pump station and 13 manhole structures up to 4.5m deep
- 1200m of conduit trench with over 5200m of DN50-DN150 conduit, including 42 precast pits and draw rope
Highlights, Innovations and Key Risks
- Success of the project was contingent on working in with other subcontractors engaged directly by the Logan Water Infrastructure Alliance (LWIA)
- Management of resources and staging of works allowed for smooth delivery over multiple work fronts
- The greenfields site is located in an environmentally sensitive area, requiring the use and regular maintenance of environmental controls to control run-off from site. Management of these controls was completed via an Environmental Controls Map (ECM) developed by FB, in collaboration with the LWIA. This allowed for an at-a-glance review of control measures and provided a simple method to monitor the condition of these controls
