YEH AND ASSOCIATES, INC

Yeh and Associates, Inc. specializes in construction inspection and consultant engineering services for transportation infrastructure projects, with deep expertise in federal highway and bridge construction oversight. The firm delivers comprehensive construction quality assurance, including field monitoring, compliance verification, and documentation control for state and federal roadways, bridges, and scenic corridor upgrades. Their technical proficiency spans inspection of earthwork, drainage systems, pavement placement, structural elements, and safety compliance under federal standards such as FHWA and MUTCD guidelines. A key differentiator is their consistent execution of complex, geographically dispersed inspection tasks across multiple states, demonstrating adaptability to diverse terrain, environmental conditions, and agency-specific protocols. The contractor maintains a strong, sustained relationship with the Department of Transportation, providing mission-critical construction inspection services across multiple regional offices. Their work supports highway rehabilitation, bridge replacement, and scenic route preservation initiatives, often under task orders issued through multi-agency contracting vehicles. This recurring engagement reflects a trusted partnership built on reliable performance, timely reporting, and adherence to federal procurement and documentation standards. Yeh and Associates operates primarily under NAICS 541330, focusing on specialized engineering services tied to civil infrastructure delivery. Their market positioning centers on niche, high-demand inspection and consulting support within the transportation construction lifecycle, serving as an extension of state DOT engineering teams. They do not engage in design or project management but excel in on-site technical oversight and regulatory compliance validation. As a small business structured as a 2L entity based in Denver, Colorado, Yeh and Associates operates without federal certifications but leverages localized expertise and regional familiarity to deliver consistent, high-integrity inspection services across the western and midwestern United States. Their operational model emphasizes agility, compliance rigor, and direct field-level technical execution.
