keeping multifaceted information on file. Rendering
this information in electronic format makes it possible
for doctors to have complete patient information right at
their fingertips, whether it is accessing lab results, fielding
a call on the weekend and being able to review needed
information via the internet, or making a referral.
“During the design stages of the center, emphasis was
placed on the migration from a partially integrated net-
working system to a fully integrated networking system
as well as security, with the ability to expand and yet to
preserve the integrity of this system,” said information
technology (IT) manager Andrew Cooper. “Today’s
technology is temporary in that today’s technology is
obsolete tomorrow,” according to Cooper.
Design Challenges and Versatility Faced
The center was faced with challenges early on, such as
being unsure how to proceed with construction of the
data center room, and knowing that the integrity of the
computer network was essential to the overall operation
of the center. Additionally, because versatility is essen-
tial to rapidly developing medical technology, consid-
erations had to include the ability to replace equipment
without an expensive retrofit.
During the initial stages of construction, the design
and layout of the data center room had not been final-
ized. Included in the design, however, were self-con-
tained HVAC systems and a raised floor system. Ralph
Butcher, city of Columbus electrical inspector, suggest-
ed the center explore the option of utilizing NEC 645
