GARDNER ZEMKE CO

Gardner Zemke Co. specializes in the construction, maintenance, and modernization of critical power infrastructure, with deep expertise in high-voltage transmission systems, switchyard components, and hydroelectric plant upgrades. The firm executes complex electrical and mechanical interventions at federal dams and power facilities, including transformer refurbishment, circuit breaker corrections, disconnect switch replacements, and cable separation projects. Their technical proficiency spans power line construction, specialized wiring installations, and the servicing of mechanical power transmission equipment such as low-voltage bushings and diesel generator systems. They demonstrate a unique ability to integrate precision electrical work with structural and mechanical upgrades in mission-critical, high-risk environments, often under stringent operational constraints at active federal power plants. The company maintains a strong, recurring relationship with the Department of the Interior, delivering essential infrastructure support for major hydroelectric projects including Hoover Dam and Glenwood Powerplant. They also regularly serve the Department of Defense, performing transformer upgrades, switchyard modernizations, and power system enhancements at military installations. Their work consistently involves high-voltage systems, substation equipment, and facility-wide power reliability improvements tailored to federal energy security standards. Their primary focus is on NAICS 237130—power and communication line construction—which encompasses the installation and repair of transmission lines, substations, and associated structures. Complementary work in transformer manufacturing (335311), specialty trade contracting (238990), and mechanical power transmission (333613) underscores their integrated approach to power system lifecycle management. They position themselves as a niche provider for federal hydropower and defense energy infrastructure, combining civil construction with advanced electrical and mechanical systems expertise. Gardner Zemke Co. is a small business entity based in Albuquerque, New Mexico, with no government certifications on record. Their geographic presence is centered in the western U.S., where they deliver mission-critical services to federal energy facilities, leveraging regional familiarity with large-scale hydroelectric and military power assets.
