Every year we bring Donnelly in to do a full diagnostic survey of all the equipment and then we make adjustments. Since the relationship started in 2002, we have not had a machine down. Immediately after Sandy, Donnelly came in and demolished the submerged units, removed them and started to rebuild them so we could be up and running. We were the first building lit on generator power after the storm. Donnelly was there when we needed them most. Donnelly’s there when we just need them. We all work really well together.
