McCain Traffic Signal Controllers

The Missouri Department of Transportation, St. Louis District is issuing a single-feasible-source solicitation for McCain ATC eX2 NEMA Controllers with EPAC DB37 D Module, with responses due June 4, 2026 by 3:00 p.m. Central Time. The sole authorized distributor for McCain Traffic Products in Missouri is Pinkley Sales Company, the only vendor determined capable of providing the controllers and factory-authorized service, warranty, and repair support for existing installations.

The scope covers routine and emergency replacement controllers needed across more than 1,200 intersections throughout the St. Louis District. The eX2 controllers are specified because their advanced functions are exclusive to these particular locations and are compatible with existing software and programming. Repairs by unauthorized facilities void manufacturer warranty and functional responsibility; MoDOT has justified the single-feasible-source determination under Missouri regulation 7 CSR 10-11.020 based on proprietary specifications, warranty requirements, software compatibility, and the requirement for factory-authorized maintenance.

The contract period runs from execution through May 31, 2027, with two optional one-year renewal periods. Pricing must be submitted by the each (EAC) unit on a Blanket Purchase Agreement basis, with Net 30 payment terms and FOB shipping. MoDOT will evaluate bids using multiattribute scoring methodology. Price increases are not permitted during the first six months of the contract or any renewal period without written justification and MoDOT approval. Contractors must register with MissouriBUYS, comply with state and federal nondiscrimination and drug-free workplace requirements, maintain adequate liability insurance naming MoDOT as an additional insured, and submit required business compliance exhibits. No pre-bid conference or site visit is scheduled. Responses are submitted electronically through MissouriBUYS.
