Our geotechnical investigation services form the foundation for safe, efficient, and cost-effective design and construction. By understanding subsurface conditions, we provide critical insights that guide engineering decisions across infrastructure, underground structures (tunnels, shafts, caverns), building, transportation, energy, and industrial projects.
Purpose and Importance
Geotechnical investigation is a fundamental step in the planning and design phase of any civil engineering project. It enables the identification and evaluation of soil, rock, and groundwater conditions, which are essential for:
- Determining soil bearing capacity and settlement behavior
- Designing appropriate foundations and retaining structures
- Assessing slope stability and landslide potential
- Evaluating seismic site response
- Managing groundwater and drainage systems
Scope of Services
Our geotechnical investigations typically involve:
- Desktop Studies and Site Reconnaissance
- Preliminary assessment using geological maps, satellite imagery, and historical site data to identify potential geotechnical risks.
- Field Investigations
- Borehole drilling, test pits, cone penetration testing (CPT), standard penetration testing (SPT)
- In-situ testing such as permeability tests, vane shear
- Geophysical surveys (e.g., seismic refraction, resistivity) for subsurface profiling
- Laboratory Testing
- Classification tests (Atterberg limits, grain size distribution)
- Strength tests (triaxial, direct shear, unconfined compression)
- Consolidation and permeability tests
- Engineering Analysis and Reporting
- Foundation recommendations (shallow, deep, mat, etc.)
- Earthwork and ground improvement advice
- Seismic site classification
- Slope and embankment stability evaluations
- Assessment of liquefaction potential
Deliverables
We provide clear, concise, and comprehensive geotechnical reports that include:
- Site description and geological setting
- Summary of field and lab findings
- Interpretation of subsurface conditions
- Engineering recommendations for design and construction
- Risk assessment and mitigation strategies
Our Approach
With a multidisciplinary team and a data-driven approach, we tailor each investigation to project-specific needs, site conditions, and regulatory requirements. Our focus on quality, safety, and communication ensures that clients receive dependable geotechnical insight for confident decision-making.
