Minnesota State Capitol Restoration



Gephart served as the design-assist electrical contractor for the Minnesota State Capitol Restoration project. With a crumbling exterior and outdated mechanical, electric and plumbing systems, the 382,915 SF Capitol underwent its first major restoration since it was built in 1905.  Gephart was tasked with modernizing the electrical and low voltage systems while adhering to the project’s guiding principles of architectural integrity, building functionality, and life safety and security.



The unique historic spaces and limited footprint of the building required meticulous planning and a great understanding of the design parameters.  Early onsite investigation was essential to identify available pathways for newly added electrical systems to be installed. Gephart’s design department provided BIM services that were utilized to coordinate and maximize the available space and to create a design that allowed all internal systems to be upgraded.

Mockups were used as a quality assurance tool to show the design team and owner what a potential finished product would look like installed.  Gephart used mockups in nearly every installed system including lighting, device plates, security cameras, and card access readers. These mockups ensured there would be no surprises during installation that could delay the completion of the project.



Gephart replaced or modified all existing interior incandescent and fluorescent lighting with LED lighting solutions. Custom, historically-inspired light fixtures were fashioned to preserve the design integrity while adhering to the mounting requirements of the building.  Over 760 historical light fixtures were able to be restored and reinstalled in their original location after making the 2,120-mile round-trip journey from St. Paul, MN to Floyd, VA to be refurbished.

Additional work consisted of installing a 13.8KV primary service and making modifications to standby power, emergency and life systems, lighting controls, fire alarm systems, DAS, security cameras, card access system, WiFi system, campus fiber, building fiber backbone, CAT 6A voice/data cabling, emergency systems intercom, 70V audio distribution system, and the House of Representative’s voting and roll call systems.



Gephart completed this extremely complex and high-profile, multi-phased project one month ahead of schedule while proposing over $1M in cost savings that were welcomed by the owner.  In addition, we exceeded the Targeted Group Business and Workforce Utilization goals set for the project by the State of Minnesota.  A key element to this success was our working with our longtime Construction Partnering Program (CPP) partner woman-owned Gunnar Electric.

Gephart Electric has been an invaluable design-assist trade partner for JE Dunn Construction on the Minnesota State Capitol Restoration project. Over the course of three-plus years, their entire team – from project management to field staff – consistently met the challenges of the project and provided the necessary actions and resources to ensure completion dates were met. Their commitment to collaboration and problem solving is first class. I look forward to working with Gephart Electric again on future projects.”

Rik Myhre, Senior Project Manager, JE Dunn Construction

As the Diversity Manager for JE Dunn, it was an honor to be a part of the project team for the MN State Capitol Restoration & Renovation project. I worked very closely not only with the JE Dunn project team and the state, but also the many trade partners to ensure that both the workforce and targeted group business requirements on the project were met. Gephart Electric, one of our main trade partners on the project, surpassed all my expectations on the diversity participation throughout the duration of the project. Not only did they exceed the goals for both minority and female workforce, but they also met the targeted group business goal for the project. The Gephart project team also played a key role in the success of the various diversity strategies such the Construct Tomorrow program, monthly diversity team meetings, and community outreach events. Working with a company that is so open to learning and embracing the diversity and inclusion participation in the construction industry has been a treat for me. I look forward to working with Gephart again soon!
