Coffman Consulting Company

The practice conducts high-fidelity physical testing of soil and rock materials to determine essential engineering properties.

• Triaxial Soil Testing

  Specific testing of soil specimens under controlled confining pressures to evaluate shear strength.

• Dynamic Soil Testing

  Evaluation of soil behavior under cyclic and dynamic loading conditions to assess seismic or vibrational response.

• Field-Scale Laboratory Testing

  Large-format laboratory testing designed to simulate complex field conditions more closely than standard bench tests.

Specialized field investigations and testing procedures are performed to evaluate environmental site conditions and containment systems.

• In-Situ Hydraulic Conductivity for Solid Waste Liners

  Direct field measurements of permeation rates in clay and composite liners to verify environmental compliance.

• Geoenvironmental Testing

  Field and laboratory assessments targeting the intersection of environmental concerns and geotechnical design.

Professional consultation, field representation, and expert opinions are provided to support legal proceedings and complex field operations.

• Expert Witness Testimony

  Independent engineering analysis and testimony for legal disputes involving geotechnical and land surveying issues.

• Offshore Technical Representative Services

  On-site engineering oversight and representation for marine and offshore operations.

• Professional Technical Opinions

  Independent reviews and engineering assessments of site conditions and design implementations.

Educational courses are developed and delivered to public and private sector engineering teams seeking advanced technical skills.

• Triaxial Testing Instruction

  Specialized training courses focusing on the setup, execution, and interpretation of triaxial tests.

• Data Reduction Methods Instruction

  Workshops targeting methods to process and analyze raw laboratory and field data.
