Infrastructure Upgrades- Cooling Tower & Chiller Replacement, Elevator Modernization, Security & MEP Infrastructure Upgrades

‍

The DW Hammer Team has been continuously working at 77 W Wacker Drive since 2017. The cooling tower & chillers project consisted of replacing 4-existing cooling towers located on the rooftop of the iconic 77 W Wacker Drive office building. The overall project was completed in 2-phases over a 6-month schedule. Originally a 24-month schedule, DW Hammer was able to cut the schedule down to 6-months by having the existing cooling towers demolished and removed using the building's freight elevator. The new cooling towers were also built in-place on the roof versus using the traditional helicopter-lift method. The build-in-place method saved the building over $350,000.

DWH completed the modernization of 19 Passenger Cabs, 1Freight, 4 Shuffle Elevators with integration of destination dispatch and put in all new custom LED Blade Floor Indicators. Installation of new building security system including Bluetooth Card Readers, Destination Dispatch Integration, Video Integration, Solo insight visitor management system and Cohesion Building Management Software. MEP Infrastructure Upgrades – including all new supplemental cooling to all elevator machine rooms, electrical infrastructure upgrades, Code Compliant upgrades to elevator pits, shafts and machine rooms.
