Macalester College Music Building: Structural & Civil Engineering for Major Renovation and Expansion

Project Overview

BKBM provided structural and civil engineering services for the complete renovation and third-floor addition to the existing Music Building at Macalester College, the first phase in the renewal of the greater Fine Arts Facility. The project involved extensive expansion, modernization, and integration with a complex campus environment.

Project Highlights

• Comprehensive Renovation & Expansion:
  • Full renovation of the existing Music Building, including the creation of an entirely new building envelope to enclose previously exposed concrete framing.
  • Third-floor addition to increase program capacity and functionality.
  • Construction of a new two-story Commons area above an existing basement foundation, connecting four existing buildings and improving campus circulation.
• Structural Engineering Solutions:
  • Framing system featured post-tensioned concrete floors and steel bar joist roofing for structural performance and durability.
  • Accommodated challenging retrofits involving integration of new construction and existing structural elements.
• Civil Engineering & Site Redevelopment:
  • Redevelopment of 3.6 acres, including a new parking lot, plaza areas, and permeable paved sidewalks for enhanced site access and sustainability.
  • Engineered site demolition, grading and drainage design, and comprehensive stormwater management systems.
  • Designed a stormwater system with 72-inch diameter perforated tanks in the north parking lot to manage runoff from both current and future campus development phases.
  • Addressed complex grading for the below-grade service door entry and routed a new storm sewer system to avoid existing utilities.
