The Department of Veterans Affairs (VA) is issuing a presolicitation notice for a sole source contract aimed at maintaining Data Innovations, LLC's laboratory analyzer VISTA interface and middleware support software. This procurement is necessary due to the proprietary nature of the software, which is essential for providing laboratory services within the VA Healthcare System for veterans. The VA's Network Contracting Office 23 intends to award a firm-fixed price contract to Data Innovations, LLC, as it is the exclusive developer and distributor of the required software. Interested vendors who believe they can meet the contract requirements may submit their capabilities to Contract Specialist Marie Weathers at marie.weathers@va.gov by June 16, 2025, although the government retains discretion over whether to pursue a competitive procurement process.
