ELECTRO-TEST & MAINTENANCE, INC

Electro-Test & Maintenance, Inc. specializes in precision electrical installation and infrastructure upgrades for mission-critical federal facilities, with demonstrated expertise in high-voltage system modifications and regulatory compliance-driven retrofits. Their work on the GDE Regulator Tank Replacement project indicates deep proficiency in nuclear energy infrastructure maintenance, including the safe deinstallation and replacement of specialized electrical components tied to radiation control systems. The contractor brings technical mastery in conduit routing, grounding systems, load transfer procedures, and adherence to NFPA 70 (NEC) and DOE Order 420.1B standards for facility safety. Their focus on high-stakes, low-tolerance environments suggests a specialization in working within radiologically controlled areas, with strict protocols for contamination control, lockout/tagout, and nuclear-grade documentation. The company maintains a focused relationship with the Department of Energy, delivering specialized electrical modifications to nuclear energy and defense infrastructure. Their engagements center on maintaining operational continuity during upgrades to reactor support systems, control panel wiring, and auxiliary power distribution networks critical to facility safety and regulatory compliance. This consistent alignment with DOE suggests a trusted role in sustaining national nuclear security and energy research missions. Electro-Test & Maintenance operates exclusively within NAICS 238210, positioning itself as a niche electrical contractor serving federal energy and defense sectors. Their market presence is defined by technical precision in high-risk environments rather than broad commercial construction, distinguishing them as a specialist in nuclear and government-regulated electrical systems. As a small, locally based entity in Black Hawk, South Dakota, the company operates as a two-person limited liability structure with no federal certifications on record. Their geographic proximity to DOE facilities likely supports rapid response and on-site coordination, reinforcing their role as a reliable, hands-on contractor for mission-critical electrical maintenance in secure federal environments.
