Tonnage of Dunnage

Big Doings Behind, Atop the Clinical Center

A 600-ton crane lifts dunnage steel to the Bldg. 10 roof. The crane worked for two full weekends and at night in order to provide a safe environment for occupants.

As part of E-wing renovation at the Clinical Center, a 600-ton crane was used to hoist steel to the roof of Bldg. 10 during the last two weekends of August.

The steel, known as dunnage, was used to support rooftop mechanical/plumbing items such as exhaust ductwork stacks and fans, energy recovery units, piping, framing, air-cooled chillers and an air-handling unit.

The project was coordinated by Jeanne Keegan of the Division of Design and Construction Management, Office of Research Facilities.
