Outstanding ratings from exhibitors and visitors
Are we headed in the right direction with BAU's concept and services? We ask ourselves this question at end of each exhibition. Which is why we had the opinion research institute TNS Infratest conduct a survey of visitors and exhibitors on our behalf again at BAU 2025. The evaluation of the surveys is currently underway.
