OWR GPS Receiver - Small Purchase with Sole Source Conditions

The Illinois Office of Water Resources (OWR) is seeking to procure a Trimble 12i GPS Antenna/Receiver or an equivalent global navigation satellite system (GNSS) integrated antenna/receiver system through a small purchase with sole source conditions. The procurement requires one new, unused GPS receiver with specific technical specifications, including a wideband UHF radio with minimum 2-watt transmission capability and RTK surveying accuracy of 8 mm horizontal and 15 mm vertical. Vendors must provide comprehensive product literature, technical specifications, and product manuals demonstrating compliance with minimum requirements. The solicitation allows for "or equal" submissions, with the burden of proof for equivalence resting on the bidder. The contract opportunity was posted on June 6, 2025, with proposals due by June 12, 2025, and requires a minimum one-year manufacturer's full coverage warranty. Vendors must submit detailed warranty information with their bid, and the brand name is used to establish quality and performance standards rather than restrict competition.

The procurement does not explicitly specify set-aside designations or restrictions on responding organizations. The specification indicates a preference for Trimble equipment or systems fully compatible with existing OWR surveying equipment and software, suggesting potential integration requirements with current technological infrastructure. While no specific incumbent vendors are mentioned, the document implies the agency currently uses Trimble surveying technology. The procurement appears to be a replacement or supplemental purchase for existing GPS surveying equipment. Though no specific budget range is detailed in the provided documentation, the procurement is classified as a small purchase, which typically indicates a relatively modest financial commitment. The standard terms and conditions document accompanying the solicitation provides a comprehensive framework for vendor responsibilities, including insurance requirements, compliance expectations, and potential performance evaluations.
