Uninterruptible Power Supply (UPS)

Walworth County is seeking bids for the removal and replacement of an Uninterruptible Power Supply (UPS) system for the Walworth County Sheriff's Department Communications Center. The procurement requires a new UPS unit initially sized to provide a minimum of 18 kVA with expansion capability to 28 kVA, operating at 208 volts three-phase input and 208/120 volts three-phase output, with a minimum of 30 minutes of run time under full load. Vendors must have a minimum of five years of verifiable experience in providing and installing UPS equipment and be authorized dealers with repair capabilities. The bid requires submission of a Certificate of Compliance, references of similar work, and a comprehensive cost summary that includes delivery, parts, equipment, materials, start-up fees, labor, travel, and installation expenses. A mandatory pre-bid meeting and site tour was scheduled for May 30, 2017, at 1:30 p.m., with questions due by May 31, 2017, at 3:30 p.m. Sealed bids were due on June 8, 2017, by 10:00 a.m. at the Walworth County Department of Public Works Purchasing Division, with a bid opening date subsequently changed to June 15, 2017, at 10:00 a.m.

There are no specific set-aside designations or restrictions on responding organizations mentioned in the bid documents. The existing UPS system is a Liebert model U125DIS25B2 unit currently operating on 277/480V three-phase power. The county is seeking both stand-alone and modular UPS system options with scalability capabilities. Vendors must provide pricing for the base installation, with optional pricing for 60 minutes of runtime under full load and dual feed configuration. The contract includes a one-year on-site warranty covering parts and labor, commencing upon system acceptance. Vendors must comply with OSHA/ANSI regulations, provide on-site training for six County personnel, and furnish insurance including Workers Compensation, Commercial General Liability, and Automobile Liability with minimum limits of $1,000,000. While no specific budget range is explicitly stated, the comprehensive requirements suggest a significant investment in a mission-critical power infrastructure upgrade for the Sheriff's Department Communications Center.
