About this file
This document is a sole source confirmation letter from ZKxKZ LLC dated March 6, 2025, pertaining to a state and local contract opportunity with Sarasota County, Florida. The letter confirms that ZKxKZ LLC's Vortex recycled modular roadway product is a sole source system developed exclusively by the company for use in the State of Florida. The product is covered by four distinct patents, including three US patents and one European patent, issued between July 2020 and May 2021.
The letter substantiates ZKxKZ LLC's unique position as the sole provider of this modular roundabout system, which is critical for the county's intended three-year procurement. The patents cover various aspects of the modular block system and roundabout construction methodology, including designs for interconnectable boards and system implementation. Sarasota County's procurement strategy allows for potential competitive solicitation if other respondents can demonstrate the ability to supply equivalent products, though the county prioritizes ZKxKZ LLC's authorized sellers.
