Yes they are link logically. I have no constrait dates except for the milestones. Please note, all my estimating and scheduling is not complete due to the client not giving me a start date. Thank you.

I see you have milestones as predecessors to a number of tasks and other milestones as successors.

You have a couple of options:
1. Set deadlines against the deliverable milestones. If predecessors slip, you'll see you are going to miss your milestone date.
2. Filter tasks using the successor field. For example, Task ID 6 "FM Pre TA LoCat" has 10 predecessors. Insert the successor field and auto filter for Task ID 6. If you want to automate it a bit more, use spare flag fields (Flag1 through Flag20) to create filters for key milestones.
3. Make sure you save a baseline and focus on those tasks whose variance is significant.
4. As you are using Project 2013 look at the task path command in the Format Ribbon. It's a marvelous way to see driving predecessors to tasks.
