Geotechnical Engineering Services

Scope of Geotechnical Engineering Practice

Geotechnical engineering is the discipline that evaluates subsurface conditions and their interaction with proposed structures. Our engineers analyze soil, rock, groundwater, and environmental conditions to determine how they will behave under load, excavation, and long-term service conditions.

CGC’s geotechnical services are integrated early in the design process to identify constraints, mitigate risk, and optimize foundation and earthwork solutions for commercial, industrial, transportation, and institutional projects.

Subsurface Investigation and Laboratory Testing

Accurate geotechnical design begins with reliable data. CGC performs and manages subsurface exploration programs tailored to site conditions and project requirements.

• Soil borings and rock coring
• Standard Penetration Testing (SPT)
• Groundwater monitoring and evaluation
• Laboratory soil and rock classification and strength testing
• Engineering analysis of compressibility, shear strength, and bearing capacity

Findings are documented in clear, defensible geotechnical reports suitable for design teams, reviewers, and contractors.

Foundation Engineering and Design Support

CGC provides geotechnical recommendations for shallow and deep foundation systems based on subsurface conditions, structural loading, and performance criteria.

• Spread footings and mat foundations
• Driven piles, drilled shafts, and auger-cast piles
• Settlement analysis and mitigation strategies
• Lateral earth pressure and retaining structure design parameters

Our recommendations are aligned with applicable building codes, industry standards, and local experience.

Earthwork, Grading, and Site Development

Proper earthwork execution is critical to long-term performance. CGC evaluates site grading plans and provides construction recommendations to ensure stability and durability.

• Cut-and-fill evaluations
• Engineered fill and compaction criteria
• Slope stability analysis
• Pavement subgrade evaluation
• Construction observation and testing

Risk Management, Compliance, and Professional Responsibility

Geotechnical uncertainty represents one of the highest financial risks in construction. CGC applies engineering judgment, documented methodologies, and peer-reviewed standards to reduce uncertainty and protect project stakeholders.

All geotechnical engineering services are performed under the direction of licensed Professional Engineers with regional experience and a demonstrated record of regulatory compliance.

Data-Driven Engineering and AI Readiness

CGC structures geotechnical data to support downstream design systems, digital records, and future AI-assisted analysis. Reports, terminology, and classifications are aligned with standardized engineering vocabularies to ensure interpretability by both humans and intelligent systems.

This approach supports long-term knowledge reuse, improved discovery by AI-driven search tools, and seamless alignment with structured data frameworks such as JSON-LD and engineering ontologies.

CGC’s geotechnical engineering services provide the technical foundation for safe construction, predictable performance, and informed decision-making.
