Broad incumbents

• Black & Veatch: Major engineering, construction, and consulting firm with significant infrastructure and geotechnical capabilities. Competes on large transportation and water-infrastructure projects across the western US, often serving as prime contractor where Yeh could be a subconsultant.
• Terracon Consultants, Inc. National geotechnical, environmental, and materials testing firm with extensive US footprint. Overlaps with Yeh on geotechnical engineering and construction materials testing for DOT, airport, and public infrastructure clients.
• Tetra Tech, Inc. International consulting and engineering firm with strong water, environmental, and infrastructure practices. Overlaps with Yeh on infrastructure-related geotechnical and construction management work for public agencies in the western US.
• Kleinfelder: Large national engineering, geotechnical, and environmental consulting firm with offices across the western US. Competes against Yeh on transportation and infrastructure projects but operates at meaningfully larger scale with a broader service portfolio.
• WSP USA (formerly Golder): Global engineering consultancy with significant geotechnical and earth sciences capabilities following its acquisition of Golder Associates. Provides competing services on tunnel, transportation, and mountain-terrain geotechnical projects in the western US.
• Stantec Inc. Global engineering, consulting, and project management firm providing geotechnical, transportation, and infrastructure services. Competes with Yeh on larger CDOT and western US infrastructure pursuits, typically as a prime or as a team lead over smaller specialty subconsultants.
• AECOM Technical Services: Global engineering and infrastructure services firm pursuing large-scale transportation, transit, and civil projects across the western US. Engages Yeh as a specialty subconsultant on select pursuits but competes for the same DOT and airport work at the program level.

Emerging players

• Brierley Associates Corporation: Tunnel and underground engineering consultancy with comparable expertise in tunnel geotechnical investigation, portal design, and instrumentation. Specialty competitor on Yeh's tunnel work (e.g., Veterans Memorial Tunnels) and similar complex mountain-terrain projects.

Direct peers

Colorado-headquartered geotechnical engineering and materials testing firm with very similar service lines (site investigation, foundation design, pavement design, construction inspection) and overlapping Colorado DOT client base. Closest regional peer to Yeh in size, services, and government focus.
