CIB, through one of its member institutes, mounts a World Congress every three years which has long been recognized as among the key events in the international building research calendar. Publications CIB considers it to be a prime task to give permanent form to the results of its activities. So a steady stream of technical reports, proceedings, recommendations, registers etc. is published. There is a bi-monthly Information Bulletin featuring highlights in CIB's life. Proceedings from the Congress and Working Commissions Symposia are published.
Membership is predominantly by institutions but individual membership is certainly possible.
With almost 500 members around the world, virtually every major building research Institute is part of the CIB family. Recent years have seen CIB Membership develop in interesting new directions. 150 Universities and Polytechniques, as well as important professional associations and government agencies have joined.
