Sedgwick County hired a single vendor to provide comprehensive preventive maintenance and on‑call/emergency support for a fleet of 22 backup generators located across county facilities. The work includes routine inspections, parts replacement, testing of automatic transfer switches and load‑bank capability (if later requested), and detailed reporting within 30 days of each service. Vendor must submit unit‑by‑unit pricing, hourly on‑call and emergency rates, and a parts markup, and must honor a one‑year warranty on labor and parts. The contract is initially for one year with four one‑year renewal options, and the county retains the right to add or remove generator sites as needed.
