With more than 2,000 employees, several of which reside in Dubuque, Bellevue, Peosta and the surrounding communities, Tri-City has proudly contributed to projects in 46 states, two U.S. territories and six countries. Tri-City Group looks forward to continuing that high-quality work, taking care of employees and customers for another century — one project at a time.
Tri-City has evolved from its roots as an electrical contractor to include low voltage technology solutions, power testing solutions, engineering and integration services, renewable energy services, drone services, structural steel erection, fire protection systems, automated solutions and robotics, millwright construction services and more. In 2024, Tri-City Group added three more companies to its family of businesses: Treiber Construction Company, Industrial Steel Erectors and B&B Masonry and Restoration. Expanding awareness of Tri-City’s full breadth of capabilities established the organization as a trusted, reliable partner to whom clients can turn for a variety of needs and projects.
Electrical contracting has come a long way since the late 1800s – and so has Tri-City Group. But while its capabilities and services have expanded over the last 130 years, Tri-City’s mission and values remain the same, keeping employees and their families, customers and communities as top priorities while redefining what’s possible in the industry.
