Umbagong District Park Pedestrian Bridges wins small projects category at the 2023 Steel Sustainability Awards.

The Umbagong District Park Pedestrian Bridges project triumphed in the small projects (under $10 million) category at the 2023 Steel Sustainability Awards. The initiative involved replacing the aging timber bridges, built in 1986, with robust steel alternatives, enhancing safety and access while preserving the park's natural beauty.

ACT Steelworks, the only SSA-certified fabricator in the ACT, led the project, collaborating with TCL architects, Sellick Consultants engineers, and head contractor Complex Co. The team aimed to minimize environmental impact, using the existing bridges as guides and leveraging natural rock outcrops as foundations, reducing the need for new materials. The new bridges were designed to be wider, accommodating pedestrians, cyclists, and mobility devices, with added features like a lookout area and seating.

Project manager James White emphasized the importance of an efficient design, using smaller steel member sizes for manual handling, eliminating the need for heavy machinery. All steel was sourced from InfraBuild Steel, optimizing material use, while existing timber was repurposed for park seating, and steel offcuts were used for plaques. Waste materials were appropriately recycled, and the steel components received corrosion protection through hot dip galvanizing and a durable PUR7 paint system.

The rusted steel finish, blending with the natural surroundings, ensured the bridges' longevity with minimal maintenance. This project showcases a harmonious blend of sustainability, functionality, and aesthetic integration, setting a high standard for future infrastructure projects in natural settings.
