Hi All

I have a very unique scenario where we have introduced P6 in a simple form into a PMO that manages the repair and rebuild of earthquake damaged homes.

Currently I have set up each address as a separate project in the EPS. I ahve done this for several reasons:

Each contract is independant- has an independent scope, budget and resources

Contracts come through intermittently and without notice

Each address is updated at a different time depending on when the project manager has visited the site.

Each contract has a schedule baseline set upon the signing of the contract

The powers at be are now arguing that we should roll the projects that we currently have underway into one singular project in P6 - creating the level one WBS as each address with the respective programmes under each WBS - so that we can assign a singular baseline to the group of projects and to report on progress from a higher level.

I am struggling to understand how we will be able to update and schedule individual addresses as we receive updates from the PM's and record the forecast completion date of that address without affecting the other 160 odd address. Also, each address currently has a baseline assigned, is it possible to keep these baseline dates assigned to each project as we roll it into one project, creating an over arching baseline from these existing dates?

Another point is that currently if we deviate massively from the project baseline each planner has the ability to rebaseline the singular address and apply it as a user baseline creating a more useful tool for the project manager to monitor progress from a singular point without affecting the project baseline - is it possible to apply a user baseline to a singular WBS?

What are your thoughts on the structuring, what are the risks and benefits you can see form each structure and do you have any tips on how to manage this singular project if the powers at be have their way?
