It is possible to extend the service life of large concrete structures in order to avoid demolishing and building new ones. It can contribute to industry and society saving in the order of NOK 100 billion, and to reducing national greenhouse gas emissions in the order of 10,000 tonnes over the next ten years.

The overall goal is to develop a generic decision-making and interaction model for choosing a management strategy for existing concrete structures, and which also includes environmental performance in the same way as cost. It involves a change of focus from demolishing and building new to rather increasing the useful life of existing structures. In addition to major savings, it will meet society's requirements for safety and help reduce the huge maintenance backlog. The vision is that the structures will have their digital twin, as a tool for efficient management, operation and maintenance.
