The VA seeks Architect/Engineer design services to replace/upgrade the fire alarm system at the Lexington VA Healthcare System, Troy Bowling Campus, covering Buildings 1, 1A, and 4, including hospital space, parking garage, and crawl space, while keeping the existing system in service until the new one is active. The A/E must perform field investigations and as-built verification, design cutover phasing, correct specified FCA deficiencies, and ensure integration with systems such as door magnets, elevators, HVAC, kitchen hoods, sprinklers, specialty suppression, door locking, smoke dampers, and duct detectors. The estimated construction magnitude is $10,000,000 to $20,000,000, and A/E service costs must not exceed 6 percent of the estimated construction cost plus related-service fees. This is a total Service-Disabled Veteran-Owned Small Business set-aside; interested firms must submit SF330 qualifications packages only, and a negotiated firm-fixed-price price-proposal solicitation will go only to the highest technically rated A/E firm after SBA DSBS verification and SAM registration. The successful A/E must provide a four-hour response time for the Lexington VA Healthcare System during design and construction-period services.
