Geological and geotechnical surveys

Why are geological and geotechnical surveys needed?

Geological and geotechnical surveys are fundamental for understanding the subsurface conditions of a site, which is crucial for safe, efficient, and sustainable construction and land development. These surveys provide detailed information on soil and rock properties, groundwater conditions, and geological hazards that directly affect the design and stability of structures. Understanding these factors early on helps DGE clients mitigate risks such as foundation failure, soil erosion, landslides, or unexpected ground movements. Early surveys enable optimized design choices, reducing costly modifications, delays, and safety issues during construction and through the lifecycle of a project.

DGE experts have delivered geotechnical and geological surveys for infrastructure, energy, and industrial developments, providing reliable risk assessments and design inputs for safe and sustainable land use.

Key elements of geological and geotechnical surveys

The surveys involve thorough field investigations including soil sampling, borehole drilling, in-situ testing, and laboratory analysis. This data forms a comprehensive picture of the site’s geotechnical properties, informing:

• Foundation design and earthworks planning.
• Ground improvement and stabilization needs.
• Safe excavation and slope stability measures.
• Assessment of risks from groundwater or seismic activity.
• Compliance with environmental and construction regulations.

The customer journey: From investigation to informed design

DGE clients start by assessing site suitability and potential risks prior to construction or redevelopment. Surveys inform engineering decisions, ensuring that structural foundations are designed to accommodate site-specific conditions. Ongoing monitoring during construction can be arranged to verify site behavior and adapt as needed.

Geological and geotechnical surveys safeguard our clients investments by preventing structural failures, improving project efficiency, and enhancing safety for workers and eventual occupants. These surveys are an essential foundation for any construction project aimed at long-term resilience and regulatory compliance.
