The VA San Diego Healthcare System in San Diego, CA, is conducting market research via a sources-sought notice to identify qualified small businesses—including SDVOSB, VOSB, 8(a), HUBZone, and other small businesses—capable of electrical preventive maintenance on its primary electrical substation systems. The work includes inspection and testing of switchgear assemblies, switches, medium- and low-voltage circuit breakers, oil-filled transformers, and protective relays per manufacturer procedures and NETA standards, plus oil sampling and infrared thermographic inspections. The contractor must provide engineering personnel, tools, and approved test equipment and deliver a comprehensive engineering report on test data, findings, abnormalities, and recommendations; repairs cannot begin without proper authority approval. The applicable NAICS code is 238210, no subcontracting opportunity is anticipated, and the VA may consider an SDVOSB set-aside if adequate responses are received, with alternate set-aside or full-and-open competition possible otherwise. Interested offerors must be registered in SAM and complete ORCA, SDVOSB/VOSB responders must be registered in SBA DSBS, and written responses are to be emailed to the listed contract specialist.
