The U.S. Army Corps of Engineers requires a sole-source justification for purchasing Aveva Edge SCADA software from InSource Solutions for $64,000. This software is essential to update existing Wonderware InduSoft Web Studio SCADA software, ensuring compliance with cybersecurity requirements. InSource Solutions is the only authorized distributor for Aveva software. Efforts to solicit bids through CHESS resulted in negative responses from all vendors, confirming InSource Solutions as the sole available source. The software is critical for operating the Dissolved Oxygen Injection System, a vital component of the Savannah Harbor Expansion Project (SHEP), which maintains dissolved oxygen levels in the Savannah River. Failure to update could halt maintenance dredging and impact harbor traffic. The procurement, under FAR Part 6.302-1, is justified by the unique brand-name software and the critical environmental mitigation it supports.
