The USGS National Water Quality Laboratory requires replacement of its aging wastewater SCADA computerized control system, originally installed in the mid-2000s, to reduce operational downtime and maintain environmental compliance. The new system must use Inductive Automation Ignition Perspective or equivalent, replicate current Genesis32 monitoring screens and alarms, and integrate with existing Allen Bradley PLC proprietary logic owned by others without violating intellectual property rights. The contractor will provide all labor, software, programming, configuration, installation, testing, commissioning, documentation, and operator training, with cutover coordinated to maintain wastewater compliance capability. This is a sources sought notice for market research only, not a request for proposals or quotations, and no contract will be awarded from responses. The applicable NAICS code is 541512 (Computer Systems Design Services) with a $34.0 million size standard, and the requirement may be set aside for small businesses or procured through full and open competition.
