Sachse Construction performed core and shell work, elevator shaft modifications, demolition, and façade restoration for the historic Marquette Building in Detroit, Michigan.

The project encompassed core and shell renovations across ten floors, including extensive foundation work to prepare the structure for a one-story vertical expansion using structural steel.

Throughout the project, the team navigated several significant challenges. Stabilizing the existing foundation was essential to support the planned upper-floor renovations. Restoring the historic façade also required careful attention to detail to preserve the building’s architectural character while replacing deteriorated terracotta. In addition to cleaning and preservation work, the team used custom molds to recreate terracotta pieces where original elements were too damaged to salvage.
