Project Highlights
  • Big room planning using lean construction process
  • Integrated steel delivery
  • Designed for future expansion

Mayo Clinic East Expansion, as part of a campus-wide growth initiative, aims to further boost patient capacity over the next two years with the addition of over 240,000 square feet of space. Four distinct areas make up this large expansion project: 1) a four-story vertical expansion to the clinic, which is also provisioned for eight additional future stories, 2) new operating rooms, 3) a new cafeteria, and 4) horizontal expansions at the loading dock, where MBJ was required to manage several complex building interactions. The loading dock was moved to the east, making room for a new basement and additional floors, while the floors above were designed to span over the new loading dock to ease the movement of trucks to and from the dock area. The operating room expansion required close coordination with the owner to meet stringent vibration criteria. Like the clinic addition, the cafeteria is also designed for future expansion.

Mayo Clinic challenged the design and preconstruction team to reduce baseline budget cost by 10 percent. Several project approaches were used to facilitate a more efficient design and construction process, starting with “big room” planning, where all stakeholders met in a proactive, face-to-face environment. Using Lean practices, the team focused on collaboration and innovation to drive value while holding a hard line on the target cost throughout the design. Big room meetings continued throughout the project and as a result, MBJ was able to identify a key integrated steel delivery process that considerably shortened the schedule. We reduced bid uncertainty by delivering a connected steel fabrication model concurrent with an early steel bid package at end of schematic design. By leveraging the team’s steel expertise and BIM automation technology, we optimized the steel member and connection design after fabricator award. As a result of these efforts, the team reduced the cost of the project by $1.1 million.
