Egis, a global leader in architecture, consulting, construction engineering, operations, and mobility services, has acquired RockSol Consulting Group, Inc., a Colorado-based transportation infrastructure firm specializing in engineering, planning, environmental compliance, design, construction management, inspection, and materials testing. The acquisition strengthens Egis’ transportation market position in the fast-growing Mountain States and West region of the U.S.
Founded in 1996 and headquartered in Thornton, Colorado, RockSol is known for the highest standard of reliability and quality in delivering highway, bridge, transit, and public works projects that enhance safety, preserve environmental resources, and improve communities. With more than 240 employees, RockSol serves municipalities, counties, state Departments of Transportation, and federal civilian agencies throughout the Western U.S.
Egis has made expansion in the U.S. and across North America its top strategic priority. The recent merger in August 2025 with the Engineering News-Record Top 100 engineering firm Lochner, together with the acquisition of RockSol, marks a significant step in the company’s growth journey toward becoming a global Top 10 professional services firm.
