What Ragnar Benson, Llc does

Ragnar Benson Construction, LLC is a heavy-civil construction firm founded in 1922 and headquartered in Rockford, Illinois, operating today as a subsidiary of MasTec, Inc. within MasTec's Clean Energy and Infrastructure segment. The company delivers three interconnected core service lines: Rail Infrastructure Services (Class 1 rail facility construction and renovation, intermodal facilities, ports, commuter light-rail stations, classification yards, mechanical repair and fueling facilities, automobile marshaling terminals, and mainline capacity improvements); Environmental Management Services (hazardous materials handling, soil stabilization, and contaminated water treatment); and Building Construction Services (general contracting and construction management for commercial and industrial markets).

The firm executes projects through multiple delivery models — general contracting, construction management, preconstruction, and design-build — applying conventional heavy-civil construction methods, specialized environmental remediation teams, and a "We Care" safety program that has earned NRC Platinum Level Safety Awards in 2016, 2017, 2018, 2019, 2021, and 2022. Primary customers are Class 1 freight railroads, with secondary segments in transit authorities, port operators, and industrial/commercial developers; Kansas City Southern is the most prominent named enterprise reference. The company is MBE-certified and recognized as a long-standing Chicago-area builder.

Ragnar Benson operates as a privately held subsidiary of MasTec, having passed through William Charles, Ltd ownership in 2005 and IEA ownership in 2018 before the 2022 MasTec acquisition. Revenue is project-based and custom-quoted with no public pricing disclosure. The company maintains a corporate website and LinkedIn presence as its primary marketing channels, plus a dedicated careers portal for talent acquisition. No software, API, AI, or data products are part of the offering — it is a pure-play services business.
