All disaster recovery services begin with damage assessments. They should be rapid, accurate, and complete. Included should be accessibility (flooding or debris), structural damage assessment, power verification, network connectivity, photo documentation along with recommendations. Fuel supplies are usually in high demand in these situations so advanced planning is important. Fuel storage and generator refueling processes should be in place prior to the event, along with ongoing operational support to insure power stays up.
Also important in recovery is structural repair, and plans should be in place for mobile welding to occur. Last but not least, is antenna and line integrity. Antennas can be twisted during strong wind scenarios and will need to be re-aligned and connectivity re-established. You will need an experienced organization with significant resources to help you recover quickly.
