MDS Engineering provided specialized electrical and airfield lighting design services for the rehabilitation of Runway 10-28 at Baltimore/Washington International Thurgood Marshall Airport (BWI). The project included a full reconfiguration of the runway’s HIRL system, new series circuit layouts, FAA-compliant fixtures, and integration with the Airfield Lighting Control and Monitoring System (ALCMS) for real-time visibility and control. Through detailed coordination and resilient design strategies, MDS delivered a code-compliant, operationally robust system that enhances airfield safety, reliability, and long-term maintainability at one of the region’s busiest transportation hubs.
