Structural deterioration affects the safety and performance of infrastructure facilities and so life extension is an area of increasing economic importance. The project will provide improved techniques for making sound assessments of the remaining safe service life of existing deteriorating infrastructure such as jetties, piers, bridges, buildings, etc. The incorporation of on-site inspection and test data will, in many cases, allow for the extension of safe service life beyond what was originally intended by the designers. This will provide substantial economic benefits since as much as 3% of Australia's GDP is lost due to corrosion and other forms of structural deterioration.

结构恶化会影响基础设施的安全和性能，因此延长寿命是一个日益重要的经济领域。该项目将提供更好的技术，以便对现有日益恶化的基础设施（如码头、桥墩、桥梁、建筑物等）的剩余安全使用寿命进行合理评估。在许多情况下，现场检查和测试数据的结合将使安全使用寿命延长到设计者最初预期的时间之外。这将带来巨大的经济效益，因为由于腐蚀和其他形式的结构恶化，澳大利亚的GDP损失高达3%。
