EXPEDITED TIMELINE DURING 2ND OUTAGE:
A great amount of planning and preparation goes into the scheduling of a maintenance outage in the power generation industry. Many tasks are dependent on the completion of others. As we work in many outages throughout the year, we understand how important it is for everyone to be flexible and accommodating when plans change. When we learned that the outage schedule was running behind, we worked quickly to increase our staff and timeline to complete our task a week early. We completed the work in 19 days, when we were originally schedule for 27 days.
