Geotechnical Engineering

Sound infrastructure begins with understanding what’s underground. DLZ provides comprehensive geotechnical engineering services — from initial site reconnaissance through final design and construction support — for transportation, water resources, and complex infrastructure projects. The work is technical and consequential: the data gathered and analyses performed directly influence foundation decisions, construction costs, and long-term performance.

With in-house drilling, laboratory testing, geotechnical engineering and construction monitoring capabilities, clients benefit from a fully integrated approach. That means the engineers designing the foundation are working directly from data they helped collect — improving accuracy, reducing risk, and keeping projects on a more efficient path from investigation to design.
