Multiple Dates sources to one set of records

[Ben Moore]

I am trying to create a list of dates from multiple tables to create a gantt chart.  My projects have Shipping dates, Installation dates and task item dates.  Each of which come from their own tables.  Is there a good way to import all of these dates into one table related to the project, each with it's own record of Start date and end date.

I'd rather have:

Project | Item | Start_Date | End_Date|

than:

Project | Install_Start_Date | Install_End_Date| Ship_date | Ship_Arrive_Date | Task_Start_Date | Task_End_date
