Abstract
There is a need for improved digital decision support in civil engineering and administration of structures. This paper describes a conceptual digital decision support platform for lifetime extension of concrete structures aiming to close gaps regarding fragmentation of current decision tools and combining economic and environmental decision making for lifetime extension activities. A current version of the platform is used in the ongoing project Excon and the paper describes remaining work towards the end of the project, future improvements outside of the project timeline, and limitations regarding the methodology used in the platform development.
