Conserving the Socks: Diagnosing and treating deterioration of the Sydney Opera House roof pedestals

A systematic review of the Sydney Opera House's concrete roof pedestals, or 'socks,' reveals evolving approaches to diagnosis and treatment, transitioning from repair-focused strategies to conservation-oriented methods. The study examines the efficacy of various diagnostic tools and therapies applied over the structure's lifespan, highlighting gaps in knowledge that require attention for long-term preservation. It also delves into the underlying structural condition by analyzing efforts to investigate and repair one component of this iconic landmark. Notably, deterioration was reidentified in 2007-2008, prompting further testing and treatment, underscoring the dynamic nature of conservation strategies.
