I am trying to complete a schedule that another planner has already started. Unfortunately, he hasn't linked his pre-construction activities together. For example, there are preparation for submittal activites with predecessor "effecvtive start date"; they all start at the same time.
My Question is, How can I link those activies in a way that I do not have them all start at the same time and not delay my construction activites. Should I look at the free float? please explain as I am new to planning.
