Empowering Growth Through Quality Construction

When Ed and Lois Altmann founded the company in 1982, they wanted to put their hard-earned construction knowledge to work.

Focusing on efficient construction, cutting-edge processes, and tried-and-true building methods, Altmann Construction quickly became one of the regions preferred general contractors.

Today, we combine decades of experience with a commitment to quality craftsmanship and collaboration. With strategic partnerships, like our work with Butler Manufacturing™, we bring value-driven construction and transparent pricing to our customers.

Our building process begins by understanding your unique needs and goals, for your specific business or organization. With a hands-on approach, we self-perform key services to maintain the highest level of quality and keep solid timelines.

Our extensive portfolio includes a wide range of commercial and light industrial construction projects including: retail, municipal, and government agencies, healthcare and medical facilities, educational, religious, manufacturing, and agricultural facilities.
