• Replace existing Plate and Frame Heat Exchanger with expanded capacity designed to use during winter months
• Replace 4160 Volt Unit Substation and Transformers with 480 Volt Unit Substation and Transformers to match new VFD Chiller requirement. Provision of redundancy to 480 Volt Transformer
• Design of BacNet DDC Controller for secondary loop to accommodate increased demand in chilled water system
• Design for required temporary power
• Design to minimize shutdown of chillers
