Is it customary to rebaseline and incorporate the changes when any of the following occur?
1. You are utilizing Rolling Wave planning and activities that were once way out in the future and had little or no details now have better information.
2. A contractor has been delayed and the client agrees with the time extensions.
3. You have four quadrants where work will take place. You originally were going to execute like North, South, East, West and now the plan is to work North, South, West, East.
4. Before the project starts you anticipate a budget of $500,000 for a contractor who will be brought in towards the end of the project. The contract amount winds up being $750,000.
Any and all opinions will be appreciated.
