Geotechnical Engineering

When structures fail or land shifts, the answers often lie underground. Secretariat geotechnical experts combine decades of engineering expertise with investigative precision to uncover the causes of soil and foundation performance issues or failures and to prevent them from happening again. We evaluate subsurface conditions, foundation and structural performance, and site stability using field investigations, laboratory testing, and advanced analysis.

Our team is trusted by attorneys, insurers, contractors, and owners to deliver clear, defensible findings in disputes, claims, and litigation. Beyond the courtroom, we partner with design and construction teams to assess risk, provide general consulting services, review designs, and support safe, resilient project delivery.

Our Expertise Includes:

  • Differing site condition assessments
  • Foundation performance concerns involving settlement, heave, and cracking
  • Retaining wall and excavation support system behavior
  • Seawalls, wharves, dry docks, and other marine structures
  • Levees, floodwalls, and dams
  • Landslides, slope instability, and subsidence
  • Pavement and roadway distress
  • Evaluation of ground improvements methods
  • Adjacent construction damage assessments
  • Ground-supported solar farm performance issues
  • Buried structure behavior including pipelines, culverts, arches, and other structures
  • Vibration and construction impact analyses
  • Below-grade leakage, flooding, and water intrusion
  • Site investigations, subsurface explorations, and laboratory testing
  • Peer reviews, independent design reviews, and constructability assessments

By integrating with Secretariat’s economic damages, construction, and forensic specialists, we provide more than technical answers—we deliver a complete picture of what went wrong, how to fix it, and the financial implications. Whether you face puzzling structural or geotechnical issues or need assurance before breaking ground, Secretariat offers clarity, confidence, and solutions you can build on.
