What RockSol Consulting Group does

RockSol Consulting Group is a privately held, full-service civil engineering firm headquartered in Thornton, Colorado, founded in 1996 to deliver geotechnical engineering, rock mechanics, and tunneling services. The firm has expanded into a multi-discipline consultancy providing transportation engineering, traffic engineering, structural engineering (including Accelerated Bridge Construction), geotechnical engineering, construction management and inspection, materials testing, and environmental services to public-sector clients across the western United States. Its core technical infrastructure includes four in-house AASHTO-accredited laboratories (Thornton, Loveland, Colorado Springs, Grand Junction) with US Army Corps of Engineers validation and CDOT Round Robin participation, supported by ISO 9001:2015 quality management certification.

RockSol serves a single-segment B2G customer base, with the Colorado Department of Transportation functioning as the anchor client across multiple flagship projects (I-25 North Express Lanes Segments 5 and 6, US 40 Berthoud Pass West Resurfacing, SH 7 Lower Permanent Repairs, SH 21 Powers and Research Interchange). The firm additionally serves county governments (Mesa County), municipalities (City of Glenwood Springs, City of Arvada), and state agencies outside transportation (Colorado Parks and Wildlife), and has delivered projects involving federal lands highway programs and NEPA compliance work.

The business model is professional services revenue generated through competitive RFP procurement and on-call task-order contracts with government buyers. Pricing is contract-based, typically structured as not-to-exceed amounts under multi-year arrangements. Distribution is exclusively direct-to-government with no intermediaries; relationships are cultivated through on-call contract awards, project performance, and long-tenured engagement (the firm's first client, secured in 1996, remains an active customer). The firm operates from six offices in Colorado, Wyoming, and California, with stated headcount of approximately 280 employees including 66+ professional engineers and 100+ construction managers and inspectors.

Broad incumbents

• Stantec: Global engineering, architecture, and environmental services firm with a large North American transportation infrastructure practice. Competes directly with RockSol on CDOT and municipal projects but at much broader scale and service breadth.
• WSP USA: Global engineering consultancy with one of the largest US transportation practices, serving CDOT and other state DOTs on highways, bridges, and transit. Direct competitor for large public infrastructure engagements, though offering a far broader portfolio.
• AECOM: Global infrastructure consulting firm with a large transportation practice serving CDOT and federal agencies. Competes with RockSol on large transportation programs, though at significantly larger scale and broader capabilities.
• Jacobs Solutions: Global engineering and professional services firm with a major transportation, water, and environmental infrastructure practice. Competes with RockSol on CDOT and municipal contracts but at vastly larger scale across multiple geographies.

Direct peers

• Kimley-Horn: Large private US engineering consulting firm with deep transportation, structural, and environmental practices serving state DOTs and municipalities. Closely comparable to RockSol in being private, employee-owned, and transportation-infrastructure focused, but at materially larger national scale.
• Michael Baker International: Engineering, planning, and consulting firm with a strong transportation practice serving state DOTs and federal agencies. Comparable in providing bridge, highway, geotechnical, and CM services to public-sector clients.
• Gannett Fleming: Employee-owned engineering firm with a strong transportation, geotechnical, and construction management practice serving public-sector clients. Comparable in size, ownership structure, and service mix to RockSol, with overlapping western US presence.
• HDR Inc. Employee-owned engineering consultancy with a major transportation practice serving state DOTs (including CDOT). Direct competitor for highway, bridge, and geotechnical engineering work with similar full-lifecycle service delivery.

Regional players

• Yeh and Associates: Colorado-based geotechnical engineering consultancy with strong tunneling and rock mechanics heritage — directly comparable to RockSol's original 1996 founding focus on geotechnical, rock mechanics, and tunneling services.
• CTL | Thompson: Colorado-based geotechnical engineering, materials testing, and construction observation firm. Closest regional competitor to RockSol, sharing the same Colorado footprint and similar geotechnical/lab service portfolio for public-sector clients.
