Overview
In 2019, a failure of Godman Army Airfield’s lighting system created urgent safety and operational risks. Building on prior work at Fort Knox, the Army Corps of Engineers engaged Iconergy to restore and modernize the airfield. The scope covered two runways, three ramps, multiple parking areas, and five taxiways. The mission: deliver resilient, code-compliant infrastructure while cutting energy and O&M costs.
Solutions
Our team deployed a comprehensive set of electrical and lighting upgrades: ~180,000 linear feet of new airfield cable, ~4,000 feet of conduit, LED retrofits across all runways, taxiways, and helipads, new Constant Current Regulators, and a modern Airfield Lighting Control & Monitoring System. The project also separated the 2400VAC system from the lighting circuits for improved reliability and installed new threshold light bars. Together, these measures restored safety, streamlined maintenance, and ensured FAA-compliant performance.
Results
The project delivered $56K in verified annual savings while providing Fort Knox with safer, more reliable airfield operations. It eliminated frequent ground faults, replaced obsolete equipment, and reduced maintenance complexity. With 100% LED runways and taxiways, the project set a new Army benchmark for resilient, efficient airfield design. Over 50,000 pounds of scrap metal were recycled as part of construction, furthering sustainability goals.
