Sustainability Project Finalists
Sulwood Drive Pavement Rehabilitation - Woden Contractors
Sulwood Drive Pavement Rehabilitation was delivered by Woden Contractors, applying a highly sustainable foamed bitumen stabilisation methodology to renew a key arterial
road in Kambah. In collaboration with specialist partners Stabilised Pavements of Australia and Downer EDI, the project maximised in-situ reuse of existing pavement materials, significantly reducing waste, haulage and embodied carbon. The works restored safety and ride quality while recycling over 6,400 tonnes of material and achieving a substantial reduction in greenhouse gas emissions compared with traditional deep-lift asphalt.

The project exemplifies how ambitious architectural design and luxury living can align with net‑positive sustainability principles.
Macgregor House - Vdara Construction & Neighbourhood Architecture
Macgregor House was delivered by Vdara Construction in collaboration with joint entrant Neighbourhood Architecture, responding sensitively to a steep site in Macgregor. The compact knock‑down rebuild achieves an impressive 8.3‑star energy rating through passive solar orientation, restrained scale and low‑carbon material choices rather than
costly technology. This carefully crafted home demonstrates how thoughtful design and precision construction can deliver high‑quality, sustainable living within a modest residential footprint.
Kings Highway and Monaro Highway Pavement Rehabilitation - Woden Contractors
The Kings Highway and Monaro Highway Pavement Rehabilitation project was delivered by Woden Contractors as two sequential, sustainability-led road renewals. Located in the
Symonston area, the works prioritised pavement recycling through foamed bitumen stabilisation, reuse of existing materials and the ACT’s first use of flyash as
a secondary binder. The project achieved significant emissions reductions, improved long-term pavement performance and delivered safer, more resilient transport corridors with minimal environmental impact.
