They are also researching the field of robotics with the aim of fully automating the examinations in five years. The concealed position of the concrete, under a layer of tiles, complicates the problem.” To solve that, the researchers attached microphones and sensors to the tile-tapping hammers used in the tap tests, enhancing the quality of the information they gather. The head of field projects at the Getty Conservation Institute, Susan Macdonald, explains: “It is often difficult to determine how well a concrete building is holding up until it the damage is already under way. Monitoring the steel-reinforced concrete of the opera house is fundamental, in order to prevent any leakage that may result in cracks ruining the concrete and putting the whole structure at risk.
The initiative funds conservative projects for modern buildings, the majority of which has employed new materials with unknown aging properties like concrete. Getty Foundation, along with the University of Sydney and Arup group are taking on the conservative operations of Sydney Opera House, as a part of Getty’s foundation “Keeping it Modern” initiative.
