Hi Forat,

First of all the recovery schedule is a revision of the Master Schedule updated on a certain data date, this revision is usuall called by the Engineer requested the Contractor to submit this recovery to show how is he going to recover the incurred delays up to date, so there are couple of questions you have to answer your self before starting it:
1- If you are on the side of the Contractor, do you think you are entitled of any EoT or you do admit that the delay is ALL caused by YOU as the Contractor, if the answer is "No" then go to step 2, otherwise, DO NOT SUBMIT a recovery schedule, first of all you have to get your EoT for the duration you think you’re entitled for, then you can submit a recovery schedule for the remaining delay caused by you (the Contractor i mean).
2- If you have finalized your EoT claim with the Engineer, or incase you are not entitled of any, then you can start analyzing your updated schedule, i would do it this way:
- Filter the longest current path (the path with the highest negative float), track the activities causing the delay and list the reasons and the ways it can be solved (increasing manpower, purchasing a new shutter system, airflight delivery,...etc).
- Discuss with your management the problem, and the options available to solve it, let the team decide whats the best thing to do, and apply the change to the schedule.
- Update the schedule, and see if there is another critical path arising after you corrected the first path, and repeat the steps above.
- If you reach at any point that the delay cannot be recovered, just report it to your management, and again let the team take the decision ( Extra Cost or Liquidate Damages) its a nice team work so do it properly and you will get the results.

My advise, dont make assumptions or commitments without consulting the project team, they will all have an input and it will always be valuable.

Cheers
