Value Delivered
We completed this large, complex HVAC system removal and replacement project without disrupting the facility’s daily operations. The retrofit took place within a 50-story building, but no outside lifts were permitted. To overcome this challenge, we applied expert vertical logistics planning to remove old equipment and bring in new using the existing building elevators.
Throughout the process, we collaborated with the general contractor to transport equipment in adherence to strict safety guidelines within the partially-occupied facility. We also worked closely with the manufacturer to ensure more than 100 new custom air handling units would fit properly into the allowable space.
Our work helped achieve a comfortable, energy-efficient environment in compliance with corporate energy guidelines. The project earned LEED Silver certification.
