Sophisticated material handling will be necessary to lower the old unit, then lift and reinstall the new unit and appurtenances. Material handling must be performed by Barnhart Crane and Rigging, utilizing method number 2 in the attached material handling engineering study. Due to majority of the work being performed inside of Hall C and at height, overall work site safety consciousness and precise project coordination with Jefferson Lab staff and project subcontractors will be vital to project success.
