The DW Hammer Team recently completed a series of projects at the iconic Willis Tower building in Chicago.  We worked alongside ESD and the building management team to design and install the infrastructure needed for (9) radio network tenants to relocate from the 102nd floor to the 101st and 100th floors.  DW Hammer installed 10 ceiling mounted (8-ton AC units and 10 Unit Heaters) which included running a secondary chilled water looped system throughout the space. The AC units are controlled by the BAS system via pumps and frequency drives.  Over 90-tons of cooling was added with all new electrical infrastructure, a pre-action system, a filtration system for condenser water, fire alarms, plumbing, new lighting, security and grounding systems.  Additionally, the team brought a 2500-AMP Service from the 104th floor ComEd Vault to a new 100th floor base-building electrical room including all new custom-built distribution gear.

The DW Hammer team installed the infrastructure needed for additional tenants to relocate their networks from the 102nd floor which included installing pumps, piping and a Lakos filter for the filtered watered cooling system. The Network Suites portion consisted of all tenants that were electrically fed from the (2) existing building electrical rooms on the 102nd floor needed to be rerouted to the new 100th floor electrical switchgear room. When the new feeds were energized, the old were demoed back to the source.  Radio station networks our team relocated included:

The Tenant Migration project consisted of white-boxing of one-third of the 100th floor where we installed new flooring, lighting, a new dry sprinkler system and painted so that the new tenants could move in.  We installed the infrastructure needed for additional tenants to relocate their network from the 102nd floor which included installing pumps, piping and a Lakos filter for the filtered watered cooling system.

The Network Suites portion consisted of all tenants that were electrically fed from the (2) existing building electrical rooms on the 102nd floor needed to be rerouted to the new 100th floor electrical switchgear room.  New conduit feeders were ran from the new 100th floor electrical switchgear room to each suite for tenants that included Cumulus, Entercomm, WPNA, ION, I Heart Radio, Trinity, Motorola, WGN and WFLD that were located on a mixture of floors from 101 – 107. Once feeders were installed, shut downs took place to remove the existing and connect the new.  When the new feeds were energized, the old were demoed back to the source.
