What Triunity does

Triunity, Inc. is a privately held U.S. professional services firm founded in Denver, Colorado in December 2003 by brothers Jonnie Thomas and Marvin Thomas, providing engineering and program/construction management (PM/CM) services to public-sector infrastructure clients. The company delivers seven core technical service lines — Program Management & Controls, Construction Management, Utilities Services (including Subsurface Utility Engineering), I&C/Electrical Engineering, Low Voltage Electrical and Security Systems, System Integration and Testing, and Intelligent Transportation Systems (ITS) — across five end markets: Transit/Railroad, Aviation, Municipal Infrastructure, Roads & Highways, and Water/Wastewater.

Triunity generates revenue through project-based professional services contracts awarded by government agencies, transit authorities, state departments of transportation, municipal governments, and port authorities. The go-to-market is enterprise field sales into the public sector, leveraging qualifications-based procurement and incumbency on marquee programs such as RTD FasTracks ($6.5B program total), LA Metro, Sound Transit, MBTA, WSDOT, MassDOT, WMATA, and Port of Seattle SEA APM. The firm operates from offices in Denver (HQ), Bellevue, and Los Angeles, and serves clients in Colorado, California, Washington, Massachusetts, Washington D.C., Texas, and New York.

In 2024, Triunity was acquired by Lochner, a national provider of infrastructure planning and engineering services; the firm continues to operate under its brand and leadership team within the Lochner organization. No public revenue figures are disclosed, and there are no funding rounds on record; the company is bootstrapped and founder-led. Customer concentration is spread across 14+ named government clients, reducing single-customer risk, and the competitive moat rests on 20+ years of past-performance credentials, deep transit/rail PM/CM talent, and incumbency on multi-year public-sector programs.
