The California Department of Public Health (CDPH) is procuring a new, modern statewide disease‑surveillance platform – the Future Disease Surveillance System (FDSS) – to replace the legacy CalREDIE system. The contract will be a single‑award, non‑cloud, on‑premises solution hosted in the State Data Center, encompassing full project planning, design, agile development, data migration, implementation, stabilization, and a one‑year Maintenance & Operations phase, with up to four additional one‑year extensions. The solicitation requires extensive certifications (CUF, DVBE, TACPA), a detailed cost workbook, and strict staffing qualifications (project manager, solution architect, business analyst, DBA, QA manager, security analyst). Evaluation will be merit‑based, scoring technical compliance, out‑of‑the‑box requirements, narrative response, and cost.
