Dallas’ Rone Engineering Acquired by California-Based RMA Companies

Founded in 1972, Rone has provided expert professional services on some of Texas’s most iconic engineering projects—including the DFW Connector, the Midtown Express, the Gates of Prosper 800-acre mixed-use development, and the Medical City Dallas expansion.

Dallas-based Rone Engineering, a leading geotechnical engineering, materials testing, and environmental services firm, has been acquired by California-based RMA Companies in a deal that expands RMA’s family of businesses.

RMA said it now has completed 11 acquisitions with leading firms throughout the nation as it builds a national platform for geotechnical engineering, environmental consulting, construction materials testing, inspection, and certification services to support the development of critical infrastructure.

“Our team at Rone Engineering is thrilled to join the RMA family of companies,” Rone President Richard Leigh said in a statement. “The partnership with RMA will accelerate our growth in the South-Central region and expand our service capabilities, so we can better serve our clients. In addition, joining RMA creates new professional growth opportunities for our team members. This is an exciting next chapter for Rone.”

Financial details of the acquisition were not released.

“The addition of Rone to the RMA family marks our seventh acquisition of 2023, which has been a monumental year of growth,” RMA CEO Ed Lyon said in a statement. “Rone operates offices in the critical Texas Triangle that is poised to receive over $17 billion in IIJA funding over the next five years. We’re excited to partner with Richard and his team to expand the services that Rone can offer their clients and to be able to serve our existing RMA clients in the Texas market. The combination of our firms will create exciting opportunities for both our clients and our employees.”
