Federal Government

Yeh has worked for and with several of federal government agencies either through our existing contracts or as a subcontractor on contracts with our teaming partners. Agencies that Yeh has worked with included: Federal Highway Administration, Bureau of Land Management, National Park Service, Bureau of Indian Affairs, General Services Administration, Department of the Interior, National Forest Service and the Division of Fish and Wildlife. Yeh makes a significant effort to meet with the various agency personnel to discuss and understand the specific agency’s requirements, procedures and end product needs. This effort and our experience with various agencies on past projects provides Yeh with a solid basis from which a high quality product will be delivered for future projects. As part of Yeh’s internal quality control, each contract is reviewed regularly at the principal level to ensure that all issues and potential problem areas are addressed and receive the attention necessary for proper resolution.

State and Local Governments

Yeh has worked for many of the state and local governments either through our existing contracts or as a subcontractor on contracts with our teaming partners. Yeh has worked for most of the county and municipal governments around our offices in Denver and Glenwood Springs. In addition, our project work in the Durango area has been for some of the local governments and with our recent opening of the Durango office, we anticipate an increase in our project work in this area. Several of the large projects have included work for Colorado Department of Transportation; Regional Transportation District; and the cities of Denver, Aurora, Aspen, and Lone Tree. We have also worked for special agencies such as the Colorado Historic Society and the Independence Pass Foundation. Work for these agencies has typically entailed the renovation and restoration of historic structures or features.

Private Sector

Yeh has worked with a wide array of private sector clients including architectural and engineering firms, commercial and residential developers and builders, mining companies, oil and gas companies and contractors. Our client’s projects have included roadways, bridges, transportation corridors, buildings, residential construction, retaining walls, temporary shoring and rehabilitation of existing structures. One very unique project we did for a contractor in the city of Aspen was the Innsbruck Inn renovation which, included geotechnical investigations, engineering design and construction observation and testing.
