SEMA Construction, Inc. is a mid-sized contractor focused on heavy civil infrastructure and related construction services. With more than 30 years of leadership in the field, the firm prioritizes safety, high-quality workmanship, and adherence to owner specifications, a performance driven by its workforce. The company acts as a full-service contractor and self-performs about 70% of major construction work scopes, enabling more rapid and flexible delivery. It is based in Centennial, Colorado. About 80% of SEMA’s work is for government entities, with most projects awarded through competitive bidding across traditional, design-build, CM/GC, and public-private partnership models. In January 2025, the North Carolina Department of Transportation selected SEMA as the Progressive Design-Builder for the US 19W Emergency Highway Reconstruction Project in Yancey County. The company has also undertaken state transportation projects in Colorado, illustrating its participation in public infrastructure across multiple jurisdictions.
