An air handling unit installation at a hospital in Seattle was a multi-team effort between Barnhart’s Mount Vernon and Kent branches in Washington. The crew first used their 155-ton Liebherr crane to lift the sections to the roof.
A total of six sections had to be installed into the mechanical room using Barnhart’s Bear Paw link and spreader bars. The work was directly above an operating room and had to be completed on a Sunday, while it was closed.
The Bear Paw was needed to navigate an elevated steel framework 3 feet from the opening. It allowed the front of the unit to be lowered while holding the rear off the structure until it was all the way in the mechanical room.
The sections were transferred to skates and moved into place. The project was completed ahead of schedule, to the delight of the customer.
