Calling for Construction and Real Estate Procurement professionals

Hi. For a new ambitious and Wordwide project, I'd like to get in touch with Procurement colleagues with experience in Construction and Real Estate at Global/Corporate level, currently based in Switzerland. The intention is to share some ideas and get a deeper understanding of the best practices to be applicable in these categories. A preference would go to people who have been working in global companies with multiple offices and locations and who have been able to create and manage global standard catalogues (f.i. McDonalds, IKEA, ZARA, etc.). If you know anyone corresponding to this profile, please let me know. Thanks for your help. Paolo
