Bid meetings and other special events can be listed by Project Owners in a number of ways, most notably within the RFP/Project documents themselves (see How do I find the Documents for the Opportunity? for more info on this). However Project Owners also have the option of using the Custom Events feature to list special Project dates and events on the opportunity page itself.
If the Project Owner has listed Bid Meetings and other special events on the opportunity page, you can find steps on how to view that information on our How do I find the schedule for a Project? page. Otherwise, please check through the available project documents or contact the Project Owner for more specific information.
