Value Delivered
We performed electrical work for the HVAC system renovation, supporting a complete rebuild of six rooftop air handling units that provide cooling for the Columbus Metropolitan Main Library.
Our team helped evaluate each piece of equipment and safe off all existing circuitry before demolition. We replaced aging electrical infrastructure, provided branch power to auxiliary devices and equipment, and helped ensure system integration with the existing fire alarm and life safety systems.
Working on a historic building, covering 250,000 square feet, required diligent planning and close collaboration with other trades.
Client Objectives
The library wanted to increase the capacity of its current cooling system, which required a complete upgrade of the system's power infrastructure.

- Modification of the existing main switchgear
