Underground expansion at the Mayo Clinic
COVER
STORY
Making Expansion Possible: Mayo Clinic
Located on rolling bluffs on the Zumbro River's south fork in
Southeast Minnesota, Rochester is the state's third largest city
and is the home and birthplace of the renowned Mayo Clinic, a
nonprofit academic medical center focused on integrated
health care, education and research. Mayo Clinic employs
more than 4,500 physicians and scientists with another 58,000
administrative and allied health staff across three major
campuses: Rochester, Minnesota; Jacksonville, Florida; and
Phoenix/Scottsdale, Arizona. Originally developed as a
stagecoach stop, Rochester has become a national destination
for medical care, drawing more than two million visitors
annually to Mayo's Minnesota location.
Since January 2022, Veit & Company has been working on
the construction of the Mayo 1st Ave Tunnel, which comprises
three tunnels (pedestrian, utility and services), and the RMC
Loading Dock projects in Rochester. These adjacent projects are
on the Mayo Clinic's ever-expanding campus and represent its
continued dedication to improvement and advancement as a
leading medical service provider in the industry.

These two projects will make way for the demolition of
the Colonial building, a patient care facility built in 1914,
and the construction of a new Proton Building. Mayo Clinic
has proton beam facilities at its locations in Rochester and
Arizona, each housing their own particle accelerator that
drives protons to nearly the speed of light before delivering
therapeutic radiation to tumors. This new facility will
further expand Mayo's ability to treat cancer patients.
Ground Conditions
Expansion of an existing, active operating facility always
poses challenges to contractors. The owner needs to maintain
access to existing facilities as well as limit the impact on daily
operations. This is compounded by the sensitive nature of the
precision medical work performed at the Mayo Clinic. This
was made even more difficult due to the extreme proximity to
the existing structures that house the robotic surgery units,
MRIs and other vibration-sensitive equipment.
