On August 28, 2018, the morning was stormy with downpour after downpour.
I arrived at the chiller hoist at 6:45am to be greeted with dark clouds rolling in. Minutes after I got to the site, the rain began. The wind shifted and the rain came at us sideways. Those of us at the job site ran for cover under a nearby bridge.
This lasted for a few hours as we milled about discussing the next steps.
Was the hoist going to be canceled? We only had a permit for so long. It wasn't ideal.
By 10am, the sun started to show and the hoist was back on. I took the elevator to the roof of a historic building near McCormick Place and could see everything: Soldier Field, Willis Tower, Lake Michigan, and more.
F.E. Moran had replaced most of the chillers on the roof of a historic downtown Chicago building. However, one row of 20-year-old chillers had yet to be replaced.
On August 28, we removed the old hood and chillers with a crane hoist. We then hoisted up the new chillers and put the hood back.
See the crane hoist below.
