SC Engineers served as the Engineer of Record for this complex project which provided an assessment and mapping of the existing direct digital control (DDC) system architecture as well as system repairs and modifications necessary to upgrade the Naval Medical Center San Diego's HVAC controls to non-proprietary, open-protocol DDC systems. The process included verification of the various protocols, network access methods, topologies, type, and capacity of each DDC controller. SC Engineers produced a comprehensive Bureau of Medicine and Surgery (BUMED) Utility Monitoring and Control Systems (UMCS) Engineering Requirements Manual that provides 23 guidelines for topics including Cybersecurity, Configuration Management, Graphical User Interface Requirements, Database Management, Point Naming Conventions, and Fault Detection and Diagnostics Software, tailored to the requirements specific to an acute care hospital. The manual provides templates for AutoCAD UMCS design and shop drawings, standard sequences of operation, and Commissioning Plans and Functional Performance Tests. SC Engineers also provided open protocol graphic templates for the UMCS Graphical User Interface software as well as design for a state-of-the-art Command and Control Center.
