McHenry County seeks a qualified GIS consulting firm to provide comprehensive enterprise‑geodatabase administration, ArcGIS Server support, custom GIS web‑application development, ArcGIS Online/Portal management, network‑administration guidance, and on‑call emergency support over a two‑year period.

The County will negotiate a contract with up to three firms after evaluating technical approach, experience, specialized expertise, staff capabilities, workload capacity, and past performance. • Enterprise geodatabase design, administration, and SQL Server reporting services. • ArcGIS Server and Portal application development using .NET, C#, JavaScript, ArcObjects, and related technologies. • After‑hours and weekend emergency response (2‑hour response time) with a formal SLA. • Training, knowledge transfer, and documentation; optional on‑site visits as needed.

Budget estimate

$300,000 – $1,200,000

No contract value is disclosed. Based on a two‑year professional‑services engagement for a county‑wide GIS program, comparable contracts in Illinois range from $300,000 to $1.2 million, depending on staffing levels, hourly rates, and the extent of on‑call support. A modest estimate assumes 2‑3 full‑time consultants at $100‑150 k per year, plus additional task‑order work, yielding a total likely between $300k and $1.2M.
