Geotechnical Engineering

With a history of saving our clients millions of dollars, our highly regarded engineering staff evaluate subsurface conditions to develop foundation and site development recommendations for planned construction through engineering, subsurface exploration, and laboratory testing. Our core areas of expertise include but are not limited to:

  • LNG plants, petrochemical, landfills, pipelines, levees

  • Commercial Development, universities, and hospitals

  • Transportation highways, roads, bridges

 

 

Construction Materials Testing

Our CMT Division produces thousands of individual reports annually for various laboratory tests and field inspection of construction materials. Most of these involve concrete, aggregates, soils in-place, and bituminous materials. Also, we regularly test brick, granite, stone masonry, mortar, and manufactured elements, such as prestressed beams and precast panels.

Geophysical Services

We possess a wide array of engineering applications to conduct near-surface geophysical explorations, such as locating underground voids, utilities, tanks, piping, potential hazards, geologic features, and anomalies, to enhance your construction projects.

Environmental Field Services

Whether it is consulting or field services for “soft” natural resource management and regulatory analysis projects or “hard” hazardous materials management projects, we have the staff and equipment resources to execute projects that support our clients’ environmental compliance initiatives.

Deep Foundations Testing

Specialized in using Pile Driving Analyzer, Case Pile Wave Analysis, & wave equation analysis (GRLWEAP) to evaluate static axialpile capacity and integrity, and provide complete driven pile deep foundation testing programs for projects of any scope and foundation type.  We also provide drivability & constructability studies, and inspector charts to evaluate the most efficient hammer systems and ensure proper driven pile installations.  

 

We are leading the industry to superior safety standards and implementing cost-effective solutions with revolutionary engineering designs.
