This project involved the construction of three occupational road crossings over Barwon Water supply channels, providing durable roadways while maintaining the integrity and operation of the water supply network for Wurdee Boluc Reservoir. Designed for long service lives and minimal maintenance, the crossings were constructed as culvert-style structures founded on reinforced concrete slabs cast within the channel floors.
Kelly Civil Construction’s scope comprised all formwork, reinforcement fixing, and concrete placement activities associated with the construction of the crossing structures. The project required close collaboration with civil contractors responsible for excavation and culvert installation to ensure excavation dimensions, levels, and subgrade conditions met the required design tolerances for the slab foundations.
Construction commenced with the placement of concrete blinding layers to provide level, clean, and structurally sound working platforms for the construction of the reinforced base slabs. Kelly Civil Construction then completed all formwork, steel fixing, and concrete pours for the structural slabs and associated concrete elements.
Our team also assisted with the lifting, placement, and securing of precast culvert sections, headwalls, and wing walls, ensuring accurate alignment and integration of the structures. Following installation, all grouting and waterproofing works were completed by our work crews to provide long-term durability and protect the structures from water ingress and deterioration.
Additional erosion control measures included the application of shotcrete to selected sections of the canal batter. These works assisted in directing water flow and reducing erosion of the natural clay channel walls, improving the long-term stability of the waterway infrastructure.
All works were undertaken in accordance with project specifications, quality assurance procedures, and stringent safety requirements while maintaining the ongoing operation of the water supply channels and surrounding road network. The completed crossings provide robust, long-life infrastructure that enhances access while preserving the functionality and resilience of the Barwon Water channel system.
