Mayo Clinic Mankato Hospital

THE PROJECT

Project Highlights

Vertical and horizontal expansions adjacent to five different existing structures
Fast-track schedule
Integrated steel delivery process

Mayo Clinic Mankato Hospital Surgery Suite Renovation and Expansion further improves the health system’s ability to provide state-of-the-art healthcare services and improve the patient experience. The project involved vertical and horizontal additions adjacent to five existing structures with five different vintages and structural systems, including cast-in-place concrete and steel. The renovation reimagined a storage space into a new surgical suite with eight operating rooms built on top of an existing emergency room. A new patient “hub” area aids in patient/public circulation and is provisioned for future expansion, based on MBJ’s study and retrofit for three future additional stories.

OUR SOLUTIONS

The vertical addition and surgical suite expansion presented several project challenges including minimized disruption to the existing hospital functions, misalignment of existing floors, and low ceiling clearance in what would become operating rooms. The project also required calculating for snow drift loads in areas not originally designed to carry the added load. As a solution, MBJ framed over the existing roof with structural steel in order to set the new roof high enough to create an interstitial space for mechanical equipment. This also aligned with the existing floor of the original hospital bed tower, an important design feature to ensure floor alignment for future expansion.

In addition to the design challenges of adding onto an existing hospital, the design was produced on a fast-track schedule using an integrated steel delivery process, which integrates the steel fabrication detailing with the overall structural design. By using BIM as a tool to begin detailing before the design was completed, MBJ reduced the shop drawing production and review time by several weeks, saving both time and money.
