The Jesse White State of Illinois Building at 115 S. LaSalle underwent a comprehensive modernization that transformed the historic high-rise into a fully functional, ADA-compliant government facility. The renovation included complete mechanical, electrical, and elevator upgrades; new building automation and IT infrastructure; enhancements to the DMV service center; restoration of the auditorium; and the integration of sustainable finishes throughout.

Completed within an occupied building, the project required detailed phasing and rigorous safety planning to protect building occupants and the public. This complex renovation revitalized a Chicago landmark while significantly improving accessibility, operational efficiency, and comfort for thousands of daily visitors and state employees, reaffirming the building’s role as a vital civic hub in the Loop.

The design team set out to seamlessly blend the building’s historic character with modern functionality. The objective was to comprehensively upgrade mechanical, electrical, and technology systems while preserving the charm and architectural integrity of the original design. A new high-rise serving elevator was added at the first floor to improve accessibility and enhance efficiency for both state operations and public use.

Interior layouts and finishes were carefully reconfigured to support agency needs while showcasing and complementing existing historic finishes. With the building remaining occupied throughout construction, the team employed meticulous planning and phased sequencing to minimize noise, dust, and disruption. Through close collaboration and thoughtful problem-solving, the project delivered a balanced design that honors the past while providing a safe, efficient, and welcoming environment for all.

Delivering a high-quality modernization at 115 S. LaSalle was a collaborative effort that demanded constant coordination, careful planning, and open communication among all trade partners. From the outset, weekly coordination meetings helped keep the team aligned as work moved through some of the building’s most complex scopes—relocating the main electrical transformer room and switchgear, upgrading HVAC systems and cooling towers, and safely performing work within active elevator shafts.

As construction progressed, the team also turned its attention to restoring the building’s exterior character, cleaning the façade and rebuilding removable dock panels to reestablish original architectural detailing. All of this work was completed under tight deadlines driven by tenant move-ins and lease expirations, requiring a phased approach and strategic after-hours scheduling to maintain progress without disrupting occupants.

Daily inspections, 3D coordination, and detailed mock-ups ensured accuracy and consistency from design through installation. Through disciplined planning, teamwork, and proactive problem-solving, the project achieved exceptional craftsmanship—successfully modernizing a historic high-rise while preserving its character and elevating it to today’s performance standards.

Safety was the top priority throughout the renovation of 115 S. LaSalle. Performing work in an occupied high-rise required rigorous planning, daily coordination, and strict adherence to comprehensive safety procedures. All crews completed site-specific training and consistently followed PPE requirements, fall protection measures, and lockout/tagout protocols.

Additional precautions were implemented for high-risk activities, including work within elevator shafts, relocation of the main electrical transformer, and exterior façade cleaning. Weekly safety meetings and daily inspections reinforced accountability and awareness across the site. The project was completed with zero recordable incidents, reflecting the team’s unwavering commitment to protecting workers, building occupants, and the public.

The renovation of 115 S. LaSalle advanced community and workforce inclusion through active apprenticeship participation and the successful achievement of MBE/WBE goals. Local trade partners and small businesses played a critical role in the project’s success, while apprentices gained hands-on experience working on a complex, occupied historic renovation—supporting long-term career growth in the skilled trades.

The completed facility now offers improved accessibility and modernized public services for thousands of Illinois residents, revitalizing a civic landmark and reinforcing the State’s ongoing commitment to community investment and inclusive development.
