Following an initial study, Puckett Engineering provided a design for replacing two B-side UPS systems with one larger UPS system for Dollar General’s data center. This included a 425kW/kVA UPS with lithium-ion battery, Maintenance Bypass Cabinet with load-bank connection, a fire-rated UPS room with floor structural reinforcement, computer room type A/C unit with redundant fans and compressors, dry-pipe pre-action sprinkler system, clean-agent fire suppression system, monitoring of UPS, battery, and A/C systems via BAS, and color-coded, detailed equipment I.D. Work sequence was developed for performing the work without disrupting data center operations. Construction admin services were also provided, including comprehensive UPS functional and battery discharge testing and A/C testing. Danny Tutt with Travis
