Manassas, VA (March 1, 2024) – Today Rinker Design Associates (RDA) announced a strategic partnership with Trilon Group (Trilon), a family of infrastructure consulting businesses. The partnership gives RDA access to additional capital and resources to expand its services in the Virginia, Maryland, and broader Mid-Atlantic markets, while better serving our clients.

RDA is a professional civil engineering and surveying services firm established in 1982. Since then, we have built a solid reputation for providing conscientious and reliable service to municipalities, governmental agencies, and private industries throughout Virginia. We take pride in offering high-quality deliverables and support services that meet project, budget, and schedule requirements, exceeding our clients’ expectations.

RDA is honored to have received numerous project awards from the Virginia Transportation Construction Alliance, the Design Build Institute of America, and the Heavy Construction Contractors Association, and most recently, we were recognized as a top 500 Engineering News-Record (#408) Design Firm, as well as a top 50 Mid-Atlantic Design Firm (#15) for 2023.

Despite RDA’s fast-paced growth over the last few years, RDA leadership identified the need for additional resources to support our growth ambitions. To achieve these goals, RDA leaders searched for a strategic partner that could help provide significant opportunities for staff to grow their careers and expand service offerings to clients.

“We believe Trilon is the ideal partner to help elevate RDA’s growth potential. Not only do they have access to capital and resources, but they have the track record and know-how on how to take AEC firms to the next level.” commented CEO Mo Kim. “We’re excited to join a family of firms across North America that are growth oriented, relentlessly focused on clients, and share similar values. I know together we’ll be able to achieve more than a standalone basis.”.

Trilon is backed by Alpine Investors, a people-driven private equity firm. It was formed with the vision of building the next Top 10 design firm in North America by bringing together the nation’s best infrastructure consulting firms. Trilon will support RDA to accelerate the growth and careers of their employees.

“We are excited to support RDA with investments in talent, technology, and targeted M&A to help them realize their growth ambitions, and we are thrilled to partner with RDA as they embark on the next chapter in their success story,” said Trilon Group CEO Michael (Mick) Renshaw. “RDA has built an incredibly strong culture that promotes performance and service. Their vision and values speak to Trilon’s intention of delivering critical infrastructure more quickly, affordably, and impactfully.”
