Specifications include, but are not limited to: The Department of Corrections (DOC) desires to establish a contract for a TUCS stationary cooking vessel via a single feasible source with TUCS Equipment, Inc., the sole source manufacturer. The stationary cooking vessel being requested by DOC is the only stationary cooking vessel with a trough design and lifting design agitator to keep food being produced in suspension, and is proprietary and only sold by TUCS Equipment, Inc. According to RSMo 34.044, a single feasible source can be utilized when the product/service requirement is proprietary and only available from a single provider. As a result, this represents a proprietary requirement that meets the criteria as a single feasible source under RSMo 34.044 and the State is pursuing this acquisition as a Single Feasible Source.
