ESD has been involved with the 77 West Wacker Drive building from its inception as the original design engineer.
A while back, the building’s original cooling towers needed a complete retrofit and replacement. Other contractors suggested using a helicopter to execute the project. With the ESD engineering team’s relationship leading the way, DW Hammer explored other options to mitigate the tremendous risk in flight.
So how does one remove old cooling towers and install massive new ones 52 floors up without a helicopter? Our team proposed that we dismantle the aging towers and bring the steel parts down elevators. Then, we explained how the new ones could be brought up elevators in pieces and assembled in place rather than dropped on the roof whole. In fact, the DW Hammer and ESD team traveled to Baltimore to the cooling tower factory to examine the manufacturing process, the quality of the products and to see exactly how they are assembled and deployed.
