On the project I am on, I can only show our Owner specific activities in the schedule as they will not approve a schedule with what my company considers a delay. With this, we escentially have two schedules for our project. Each month we update a schedule and then I copy that schedule, delete out certain asbuilt activities and ensure that the floats are the same. I did a comparison between the two schedules and all the start and finish dates matched for all the activities but the float values were different for some of the activities. How can this be?
