This acquisition will provide RS&H a substantial presence in the Colorado market.

CHARLOTTE, NC – RS&H, an employee-owned architecture, engineering and consulting firm in the United States has acquired Tsiouvaras Simmons Holderness (TSH), a Colorado-based transportation engineering and consulting firm. RS&H was advised exclusively by 7 Mile Advisors, a Charlotte based M&A advisory firm, on the the transaction.

Based in Jacksonville, FL, RS&H ranks as ENR’s #65 Top Design firm and has expanded from its roots in the Southeast to provide services nationally. The transaction provides RS&H with a substantial presence in the Colorado market, which the firm has served through its Aerospace & Defense, Aviation, and Corporate Practices since 2005. RS&H is also currently performing construction assessments and independent assurance testing services as owner representative for the $2.2 billion Central 70 Public Private Partnership (P3) in Denver.

Building on this momentum in the state, TSH brings an excellent reputation for innovative planning and design of complex infrastructure projects as well as construction project management, administration, and field observation. Clients include state and local governments, as well as heavy civil construction contractors engaged in design-build projects. TSH is currently designing the I-25 Express Lanes project in concert with the Kraemer-IHC joint venture, in addition to several other state and local transportation projects.

“TSH’s staff is well-respected in the Colorado market for high-quality work and a commitment to their clients and employees,” said RS&H CEO David T. Sweeney. “We look forward to working with our new partners to continue to serve TSH’s existing Colorado clients as well as extend the full spectrum of our joint capabilities to existing and new clients in the West.”

“Highly strategic acquisitions among AEC firms, like RS&H’s acquisition of TSH, are providing tremendous value in terms of competitive advantage and sustainability, especially for privately-held companies. A combination between an industry leader like RS&H and a highly desirable firm with a niche market position, as TSH has in Colorado, provides for mutual opportunities neither firm could achieve on their own. At 7 Mile Advisors, we pride ourselves on helping our clients navigate and close the right transactions for their long-term strategies.” says Neil Churman, Director at 7 Mile Advisors and leader of the firm’s AEC practice.
