McKenneys completed an HVAC overhaul for an Assurant office tower, replacing a chiller plant and the supporting air handling units (AHUs) with no building downtime.

The ChallengeThe insurance provider needed to remain oper-ational while a rooftop chiller plant and AHUs on each floor were replaced. The mechanical room had significant space constraints for the

chiller plant and new AHUs had to be disman-tled to fit through 36" doorframes. The build-ing also required a complete controls retrofit to increase visibility and energy savings.

The SoluTionUsing a crane over two consecutive week-ends, McKenneys demolished the existing chiller plant, then staged all the new material, including prefabricated piping, for delivery to the roof. Mezzanine level walls were removed,

then rebuilt, to accommodate the new equip-ment as it was installed. During multiple weekends, the team also carefully organized the new AHUs breakdown, delivery to each floor, and reconstruction in the shortest amount of time.

The ReSulTSThe new chiller plant, AHUs and system controls were successfully installed with no disruption to Assurants building occupants.
