Preparing recovery or revised schedules is a very common task during project execution, monitoring and controlling. When there is a slippage in the project finish forecast date or scope addition or omission or a change in the construction methodology or constructability method, the schedule baseline is no longer effective in the monitoring and controlling process.
Therefore, a recovery or revised schedule should be prepared, approved and maintained as a new baseline to monitor and control the project. However, there is a difference between a recovery and a revised schedule as follows:
Recovery schedule: if there is a slippage in the project finish forecast date because of one of the above-mentioned factors but the project team still believes that there is a realistic chance of completing the project on time by taking additional measures, then the contractor may be requested to submit a recovery schedule.
Revised schedule: if there is a slippage in the project forecast finish date because of one of the above-mentioned factors and the slippage is so much that the project completion date is no longer realizable, the client may request, and the contractor may submit a revision of the schedule with a new, realistic completion date.
