The Missouri Department of Transportation, St. Louis has determined that there is only one known approved distributor, MoboTrex, Inc. to provide repairs for Yunex, formally known as Siemens TS2/Type 2 controllers, Siemens TS1/TS2 controllers, and Siemens Eagle EPAC controllers for the St. Louis District. St. Louis District does not outright purchase new Siemens/Yunex controllers any longer. This SFS is for the constant repairs needed. Job number JS63088 from 2014 involved 800 plus of these Siemens/Yunex installed on our intersections. 600 plus controllers are still running our intersections. This will be an ongoing requirement. Repairs by unauthorized repair facilities could void any warranty and/or functional responsibility on the part of the respective manufacturer. This notice shall meet the single feasible source posting requirements for one calendar year and in association with the needs described. Contract Period: April 11, 2025 - April 10, 2025
