Current structural engineering is still predominately driven by a spirit to design and build new structures. The structural engineer’s vocation is to design and build, even when dealing with existing structures. For many structural engineers, the opinion still prevails that an existing structure has a finite service life of 80 to 100 years and then needs to be replaced by a new structure. While this spirit was perhaps rational 50 years ago, it is nowadays far away from modern society’s demands calling for a focused approach on the built infrastructure. Existing structures are an asset and wealth of a society, and structural engineers are more and more often called upon to maintain and enhance existing structures and infrastructure effectively, within the availability of limited (public) funds, instead of replacing existing structures by new construction.

Monitoring of existing structures

Getting more out of existing structures = smart monitoring and efficient assessment
