Mill City Museum: Structural & Restoration Engineering for Historic Mill Renewal

Project Overview

BKBM provided engineering design services for the restoration and adaptive reuse of a landmark 19th-century mill complex in Minneapolis. Originally built in 1879 and having survived three devastating fires (1928, 1991, and 1996), the project focused on transforming the historic ruins into a vibrant cultural, educational, and community resource.

Project Highlights

  • Historic Restoration & Stabilization:
    • Designed both temporary and permanent bracing systems for nine stories of rubble wall shell to ensure site safety and structural stability during and after construction.
    • Conducted a comprehensive evaluation of the complex’s structural integrity and renovation potential for its transformation into the St. Anthony Falls Heritage Center.
  • Adaptive Reuse & Modern Amenities:
    • The renovated facility now houses an Interpretive Center, open and private offices, exhibit spaces, a museum store, classrooms, and a cafeteria.
    • Sensitive restoration preserved the character and authenticity of the historic mill while enabling modern programming and building systems.

Engineering Solutions

BKBM developed custom structural bracing strategies to stabilize fire-damaged rubble masonry, protect historic elements, and safely accommodate new uses. Engineering analysis ensured the integrity of the existing shell, supporting sustainable reuse and cultural preservation.

Results & Impact

The Mill City Museum project reimagined an iconic industrial site as a leading destination for history, culture, and education. BKBM’s engineering enabled the safe restoration and long-term viability of the complex, supporting the museum’s mission to engage the community and celebrate Minneapolis’ industrial heritage.
