Project Highlights
  • 11-story, 200,000 SF headquarters
  • Largest downtown development in Duluth history
  • Cast-in-place, post-tensioned concrete and structural steel
  • Significant lateral system designed for Exposure D wind loads

maurices Headquarters, spanning an entire city block in the heart of downtown Duluth, is the largest downtown development in the city’s history. The result of a public-private collaboration, the 11-story, 200,000-square-foot office building serves as the headquarters for the leading retailer of women’s clothing and accommodates 600 employees. Essentially three buildings in one, the complicated project features a two-story grand entrance lobby and retail space at the ground level with two connections to the skyway system on Level 2, a 500-car parking structure for the city of Duluth integrated into Levels 3-6, and open office floors on Levels 7-11. The project also includes a fitness center and a rooftop terrace overlooking the city with views of Lake Superior. The large mixed-use development establishes Duluth as a destination and signifies the growth and potential of the city.

  • Structural engineering


Due to the building’s location in downtown Duluth adjacent to Lake Superior, the structure was required to meet Exposure D wind loads. To address this high wind load, MBJ designed a more significant lateral system than a typical 11-story building would require. The structural systems are cast-in-place, post-tensioned concrete on Levels 1-7 and steel-framed slab on metal deck on Levels 8-11, as well as the roof. The transition from a post-tensioned concrete parking facility to a steel office building required significant coordination at the interface between the two. The elevator core was surrounded by braced frames at the office levels, while the braced frames were embedded into the concrete core at the parking levels due to the high Exposure D wind loads. MBJ also utilized rock anchors to assist with resisting overturing at shear walls.

The foundation is shallow drilled piers bearing on high-capacity bedrock. The building’s location on a significant hill presented a fair amount of unbalanced earth pressures that required perimeter basement/retaining walls at the up-hill side of the site for resistance. While the front entrance to the building is at Level 1, the parking access is at Level 2 from the adjacent street. A covered entrance to the parking was built between two historic buildings along with a bridge over an alley to access the parking facility. Significant coordination was also required to tie the building to two existing skyways.

The LEED Silver-certified headquarters features reclaimed materials and substantial glass windows on the upper levels that let in natural light.
