Chiller Replacement Roybal Campus

The Centers for Disease Control and Prevention issued solicitation number 75D301-26-R-73398 for design-build services to modernize the Building 10 central plant at the Roybal Campus in Atlanta, Georgia. This project is designated as an SBA (SBA) set-aside under NAICS code 238220 for Plumbing, Heating, and Air-Conditioning Contractors and PSC Z2AA for REPAIR OR ALTERATION OF OFFICE BUILDINGS. The objective is to replace aging chilled-water plant equipment and improve electrical and controls infrastructure while maintaining continuous campus operations. Simi Khera is the point of contact for this requirement, and responses for this combined synopsis/solicitation are due by June 15, 2026.

The scope of work involves replacing four existing 1,450-ton chillers with new 1,800-ton units, including associated starters, controls, piping, and refrigerant monitoring. The contractor will also replace nine existing cooling tower cells with eight new cells, which requires structural modifications, roofing work, and updated maintenance access. Further requirements include replacing primary chilled-water pumps, condenser-water pumps, and associated starters or variable frequency drives. The project encompasses medium-voltage and low-voltage electrical upgrades, BAS/controls integration, and fire protection modifications to deliver a fully commissioned facility.

Execution must be phased to ensure that no more than two chillers are removed from service at any time, preserving campus operations throughout the performance period. The acquisition provides for all design, engineering, management, labor, and equipment, as well as testing, commissioning, and training. The solicitation, published on April 23, 2026, includes six attachments: a Contractor Non-Disclosure Agreement, a Contractor Employee Non-Disclosure Agreement, a Visitor Request form, a Wage Determination, a Statement of Work, and the solicitation document.
