Sanford Middle School Addition & Renovation: Structural Engineering in Minnesota

Project Overview

BKBM provided structural engineering services for a major modernization and expansion of Sanford Middle School, a historic facility in South Minneapolis. The goal was to preserve the school's historic character while providing new, flexible spaces to accommodate a growing and diverse student population.

Project Highlights

  • Modern Expansion within a Historic Context:
    • Demolished a portion of the existing 3-story, 1920s concrete-framed school to make way for a new 60,000 SF, four-story steel-framed classroom addition, and a 7,000 SF gymnasium.
    • New additions were nestled into the existing structure and immediately adjacent to the historic auditorium, ensuring a seamless connection between old and new.
  • Respectful Historic Integration:
    • Salvaged original stonework and introduced new architectural features to authentically merge modern construction with the historic facade, meeting community feedback for preserving school identity.
  • Challenging Structural Modifications:
    • Upgraded and adapted the historic structural system to accommodate modern mechanical systems.
    • Worked collaboratively with the contractor throughout construction, addressing unforeseen and complex existing conditions quickly and creatively to keep the project on track.

Engineering Solutions

BKBM’s approach combined careful assessment of historic framing with innovative design strategies to accommodate new mechanical systems, code requirements, and community expectations. Close coordination and ongoing problem-solving with the entire construction team were essential for integrating structural upgrades within the project’s tight urban footprint and historic envelope.

Results & Impact

The Sanford Middle School project delivers modern, flexible learning spaces while celebrating the site’s architectural legacy. The resulting facility meets the demands of current and future enrollment, reflects community values, and preserves the historic character of a beloved Minneapolis institution—ensuring it remains a cornerstone for generations to come.
