Renovating and upgrading electrical infrastructure in existing healthcare facilities presents a distinct set of challenges, where legacy systems, space constraints, and ongoing operations must be balanced against current code requirements. This presentation focuses on electrical design within remodel and renovation projects, where applying new standards to existing conditions requires both sound engineering judgment and practical constructability considerations. With an emphasis on the 2026 updates to the FGI Guidelines and NFPA 70, this session will explore how evolving requirements impact the evaluation and design of electrical systems in existing facilities. Particular attention will be given to diagnostic and patient care spaces, where system reliability, redundancy, and code compliance are critical to patient safety and clinical operations. Topics will include the application of current codes to partial renovations, maintaining compliance within constrained infrastructure, and determining when upgrades to essential electrical systems are triggered. The session will also examine how these code changes influence the design review process, including identifying compliance gaps, coordinating phased construction, and aligning engineering solutions with both regulatory expectations and real-world installation constraints. Presented jointly by a design engineer and an electrical contractor, this session will offer both design and field perspectives, highlighting practical challenges, lessons learned, and strategies for delivering code-compliant solutions that are also constructible and maintainable. Attendees will leave with practical tools to more effectively evaluate existing conditions, anticipate code-driven design impacts, and avoid common pitfalls that can lead to costly redesigns or construction conflicts - ultimately improving both project outcomes and coordination across the design and construction team.
