The official fib Congresses or Symposia are organised on behalf of the fib by one of its National Member Groups. The Congresses take place once every four years. The Symposia are organised every year except when a Congress takes place.

The ICCS (fib International Conference on Concrete Sustainability) takes place once every four years. The main objective of the conference is to contribute to sustainable development through dissemination of advanced knowledge which is based on research results and developments in the fields of concrete structures and associated technologies. 

The International Symposium on Conceptual Design takes place every two years. It is a one-of-a-kind event specifically addressed to creative designers of all experience levels.

Meetings of fib's bodies (for ex. General Assembly, Technical Council, Commissions or Task Groups) are as much as possible held in conjunction with these events.
