One Cardinal Way | St. Louis, Missouri
Zagarri Engineering implemented an Emergency Responder Communication Enhancement System (ERCES) at One Cardinal Way, the 29-story residential tower overlooking Busch Stadium in downtown St. Louis. The system was designed and implemented using ADRF public safety equipment to provide reliable in-building radio coverage for emergency responders and meet the requirements of the St. Louis Fire Department.
Zagarri Engineering provided the RF engineering and system integration necessary to enhance public safety radio communications throughout the high-rise facility. Since completing the system in April 2021, our team has continued to support One Cardinal Way through annual ERCES inspections, RF coverage testing, system maintenance, and compliance documentation for the St. Louis Fire Department.
This ongoing partnership helps ensure the system remains operational, compliant, and ready to support reliable emergency responder communications throughout the building.
