The Sydney Modern Project marks a major expansion of the Art Gallery of New South Wales, transforming the 153-year-old institution into a unified, two-building cultural campus. The addition of the new Naala Badu building to the north of the original gallery, now known as Naala Nura, has almost doubled exhibition space and introduced a sequence of galleries, public spaces and landscapes that connect art, architecture and the surrounding environment. Since opening, the expanded gallery has attracted more than two million visitors in its first year of operation.
Designed by SANAA, the new building responds closely to the site’s complex topography at the edge of The Domain, adjacent to Sydney’s CBD. The project spans a steep escarpment and bridges over the Eastern Distributor motorway, while also incorporating two decommissioned Second World War naval fuel tanks embedded in a former sandstone quarry. A series of interlinked pavilions is arranged across five levels, allowing the building to sit lightly within the landscape while establishing strong physical and visual connections across the site.
The architectural concept prioritises openness and flexibility, creating new types of spaces for exhibitions, performance and learning. The expansion enables a broader presentation of the Gallery’s collection and provides a significant new platform dedicated to Aboriginal and Torres Strait Islander art and culture, reinforcing the Gallery’s civic and cultural role.
Structurally, the building comprises interconnected steel-framed systems supported by a reinforced and post-tensioned concrete podium formed within a deep excavation. Extensive use of existing structures informed the foundation strategy, addressing the site’s constraints while enabling the architectural vision. Delivered through collaboration between the Art Gallery and Infrastructure NSW, the project brought together Architectus as executive architect, Arup as multidisciplinary engineer, Richard Crookes Constructions as lead contractor, and Australian-fabricated structural steel supplied and erected by Samaras, demonstrating the central role of steel in achieving this complex and highly integrated cultural development.
The Hinuera Sheds project demonstrates how steel can play a central role in more sustainable construction. Using around 380 tonnes of structural steel, including nearly 200 tonnes of repurposed Steltech beams from a demolished building, the project shows how existing steel can be given a second life without compromising performance or safety. This approach significantly reduced the need for new materials and lowered the building’s embodied carbon.
Rather than designing first and sourcing materials later, the structure was engineered around the available recycled steel. Engineers, fabricators, and the construction team worked closely to inspect, adapt, and integrate the reused beams into the final design, proving that reclaimed structural steel can meet modern standards and support large, high-performance buildings.
Beyond steel reuse, the project incorporates solar panels, rainwater collection for firefighting, and large-scale native planting, creating a facility designed for long-term efficiency and low environmental impact. Together, these elements reinforce steel’s compatibility with sustainable building systems and circular design principles.
Awarded the 2024 Sustainability Award, Hinuera Sheds stands as a clear example of how steel construction can move beyond recycling to true reuse. The project highlights steel’s durability, adaptability, and long lifecycle, positioning it as a practical and effective material for delivering environmentally responsible construction today.
The Oohi Bridge West Viaduct is a three-span continuous steel box girder bridge with an orthotropic deck, delivered in Okayama City under an Early Contractor Involvement (ECI) system to minimise disruption to National Highway 2. The viaduct is 149.3 m long and comprises approximately 1,250 tonnes of structural steel.
A key design decision was the change from a concrete to a steel intermediate pier, enabling an integrated superstructure–pier large-block erection. This approach allowed the central span to be installed in a single night using multiple-axle special bogies, significantly reducing traffic closures while improving construction efficiency and safety.
Large steel blocks of up to 600 tonnes were assembled at ground level and transported using bogies with a combined capacity of 1,500 tonnes. Detailed structural analysis addressed load distribution, pier inclination and temporary stresses, ensuring stable and accurate installation within a constrained urban site.
Further steel-based design changes, including steel wall railings and high-strength bolted connections, shortened the overall construction programme. The use of BIM and CIM supported erection planning, traffic management and coordination with stakeholders, contributing to the project’s recognition as Innovation of the Year in 2024.
This project addresses a critical challenge facing the construction sector: reducing embodied carbon while enabling circular economy practices and design for disassembly. By rethinking the steel–timber interface, it responds to the limitations of conventional composite flooring systems, which typically restrict effective disassembly and reuse. The development of novel steel-to-timber shear connectors allows composite action while enabling structural components to be separated and reused at end of life, aligning with the objectives of the European Green Deal.
The core innovation lies in the connector design. By combining a dedicated shear connection device with bolted fixing, the system achieves high load-bearing capacity while protecting timber elements from damage during installation and disassembly. Laboratory testing, including push-out tests and full-scale beam tests, confirms structural performance comparable to established composite systems, with minimal slip under service conditions and limited permanent deformation at ultimate states.
Beyond structural performance, the solution delivers clear practical benefits for implementation. The connectors support demountability, preserve the integrity of steel and timber components, and enable reuse without compromising capacity. Together, the technical validation, robust performance, and alignment with circular construction principles explain why the project has been selected for recognition.
