This is a mechanical and electrical design document for the Georgia World Congress Center (GWCC) Authority's GESPC II Building C Chilled Water Plant Upgrades project, prepared by TLC Engineering Solutions, Inc. The project involves comprehensive modifications to the existing chilled water plant located in Building C, including replacement of water-cooled chillers and hydronic pumps, as well as replacement of secondary heating hot water pumps. The scope encompasses three new Trane CVHF water-cooled chillers (one 1,300-ton unit rated at 4160V and two 1,000-ton units rated at 480V), multiple new circulating water pumps including primary and secondary chilled water pumps, condenser water pumps, and heating hot water pumps manufactured by Bell & Gosset. The design includes installation of new refrigerant monitoring panels compatible with R-514A refrigerant, electromagnetic insertion flowmeters (Onicon F-3500 or equivalent), temperature sensors, and BTU meter interface displays. New variable frequency drives with electronic bypass capability are specified for pump operation, and all equipment requires vibration isolation on concrete housekeeping pads with inertia bases. The electrical scope includes connection of existing feeders to new chillers, installation of new breakers and feeders for new equipment, and integration with the building automation system's direct digital controls (DDC) for monitoring operating KW and KWH.

The design specifies detailed mechanical and electrical demolition requirements, including removal of existing 1,100-ton water-cooled chillers, disconnection of refrigerant and electrical services, and reclamation of refrigerant prior to demolition activities. All equipment connections must be verified with manufacturer certified drawings, and field modifications such as piping or ductwork offsets required due to obstructions shall be provided at no additional cost to the contractor. The project requires coordination with existing building elements and other trades, with minimum 6-inch clearance maintained between ductwork and fire-rated partitions. All piping penetrations must be sleeved and sealed, and manual air vents shall be provided at high points in chilled and hot water systems. The electrical connection schedule indicates feeder sizes and circuit requirements for each piece of equipment, with copper conductors rated for MV-90 5KV service. A communication restriction is in effect for this procurement, prohibiting interested firms from communicating with Authority staff, GWCC officials, or their consultants except through formal question submission processes. Finalists and apparent awardees are further restricted from making public statements or press releases regarding their selection, with violations subject to submittal rejection.
