Consolidating electrical services across six buildings on an academic medical center campus, with over a million square feet, and with no disruption to service is no small undertaking for the engineering team at BSA LifeStructures!
Memorial Medical Center in Springfield, Illinois, recently opened its new Patient Care Tower, along with several other projects, through its “Advancing Care by Design” campaign. Some improvements to the existing electrical infrastructure of the campus were undertaken at this time, but additional upgrades were required.
BSA LifeStructures kicked off the “South West Electrical” project with completed schematic designs in October 2015 and construction beginning in January 2017.
Key design considerations included:
Planning for this project took over eighteen months due to extreme complexity and extensive survey work. Many services, such as medical gas, water, and mechanical duct work, needed to be relocated to make space for electrical conduits.
A few significant project metrics identified:
Emergency Power Capacity
Two new 2000 kW generators were installed and paralleled with existing 1500 kW generators for increased emergency power capacity. With the increasing number of equipment and devices requiring emergency power access, it was determined that 2000 kW generators were necessary to accommodate estimated future loads. Because of these larger new generators, the existing paralleling gear required custom modifications to accept the larger-associated over-current devices.
The existing service building on campus houses the generators and paralleling gear. This building is located 1,600 feet from the new electrical building where all electrical services are centralized. Because of this extensive distance, two step-up transformers were installed at the service building to increase feeder voltage from 480 V to 12.47 kV for campus distribution. Each transformer is capable of carrying the entire emergency load, providing necessary redundancy for the emergency power system.
A project of this magnitude requires considerable planning and strategic effort. With a true partnership between Memorial Medical Center and BSA LifeStructures, Phase One of the South West Electrical project will be completed in April 2018, just 15 months after breaking ground.
At BSA LifeStructures, we engineer inspired solutions to improve lives.
