Abstract: When schedule delays impact important contract milestones beyond key deadlines, a recovery schedule may be the only chance a project has to achieve those milestones. This paper will explore lessons learned from two projects that were significantly delayed and used recovery schedules to achieve project success. This paper will also discuss guidelines from the AACE Recommended Practice 54R-07, “Recovery Scheduling – As Applied in Engineering, Procurement, and Construction.” Essential to recovery schedule success is the decision by project shareholders to revise the definition of project success as accomplishing only the most important project goals. The recovery schedule is then developed by revising the original schedule logic to allow for additional resources to work concurrently. The use of targeted overtime for critical and near critical activities, as defined by updates of the recovery schedule, is another important recovery tool. The recovery schedule is also used to warn against any future owner responsible activities (i.e. shop drawing approvals, permits, inspections) that could impact the accelerated project. This paper will also discuss recent case law pertaining to recovery schedules.
