Your project benefits from our unique and innovative approach

Geotechnical Engineering

Subsurface is our specialty; engineered for performance

Our engineers and geologists utilize local knowledge combined with a variety of exploration methods and advances in technology to characterize the subsurface aspects of each project site. Moreover, our geotechnical engineers’ direct interaction with our clients is integral to maintaining efficient progress from design to construction.

You must inspect what you expect

Our Construction Service Professionals provide experience and capabilities specific to construction engineering and materials testing and special inspection services. Our certified staff is extensively trained, providing reliable, timely, and accurate engineering, inspection, and testing information to advance key project objectives that benefit construction efforts, schedule, and overall quality.

As documentation is key, we have employed a user-friendly reporting program, MetaField®, allowing for efficient and proactive scheduling, real-time and electronic reporting, deviation tracking, and equipment calibration and personnel certification validation and storage. As a result, project stakeholders can instantly access the documents they need, enabling efficient communication and collaboration, as well as greater transparency across the entire project team.

Laboratory Testing

Accuracy, Efficiency, Timely; Advanced laboratory proficiencies

We offer three laboratories nationally accredited by the American Association of State Highway Transportation Officials (AASHTO) across our geographic footprint; Boise and Idaho Falls, Idaho, and Spokane, Washington, respectively. Each accredited laboratory meets or exceeds federal, state, and/or local jurisdictional requirements. Further, our laboratories perform many advanced engineering and construction material tests to support both design and construction.
