Subsurface Intelligence

See more below ground before construction begins.

Geophysical surveys provide non-invasive and minimally intrusive methods for investigating subsurface conditions. For construction and infrastructure projects in Singapore, engineering geophysics can complement conventional soil investigation by helping project teams evaluate geological variability, buried features, underground utilities, possible voids and other subsurface conditions across a wider area.

Subsurface Investigation

Support preliminary assessment of ground conditions before excavation, foundation, tunnelling or other construction activities.

Utility & Feature Detection

Assist in identifying buried utilities, structures, interfaces and anomalous subsurface features where suitable geophysical methods can be applied.

Engineering Interpretation

Convert field measurements into engineering-focused interpretation that can support planning, risk review and subsequent investigation.

Survey Methods

Geophysical methods selected around the engineering question.

No single geophysical technique is suitable for every ground condition or project objective. Survey methodology should be selected according to expected geology, investigation depth, target size, site access, surface conditions and the required engineering output.

Ground Penetrating Radar (GPR)

GPR survey can support detection and mapping of shallow buried services, structural features and interfaces where ground conditions are suitable for radar penetration.

Electrical Resistivity Survey

Electrical resistivity methods can investigate variations in subsurface electrical properties and may assist assessment of geological boundaries, weathering, groundwater-related conditions and anomalous zones.

Seismic Refraction

Seismic refraction surveys use the propagation of seismic waves to support interpretation of subsurface velocity layers, depth to stronger material and changes in ground conditions.

MASW & Surface Wave Methods

Multichannel Analysis of Surface Waves can be used to develop shear-wave velocity profiles and support characterization of near-surface ground stiffness.

Survey methods and achievable investigation depth depend on project objectives, site constraints and actual ground conditions. A project-specific methodology should be developed before field deployment.

Singapore Applications

Built for construction and infrastructure decisions.

Deep Excavation

Additional subsurface information for excavation planning, ERSS-related assessment and investigation of ground variability around proposed works.

Transport Infrastructure

Geophysical investigation for rail, road, station, tunnel and other transport infrastructure environments.

Building Development

Support redevelopment, foundation planning, existing structure assessment and investigation near adjacent buildings.

Underground Utilities

Non-destructive investigation to supplement available records and support safer planning around buried services and subsurface assets.

Site Investigation

Complement boreholes, sampling and laboratory testing by extending interpretation between conventional investigation points.

Ground Risk Assessment

Target potential anomalous areas for further investigation before critical excavation, drilling or foundation activities.

Integrated Investigation

Geophysics works best when integrated with engineering geology and soil investigation.

Geophysical measurements are indirect observations of subsurface physical properties. The strongest engineering interpretation is therefore normally achieved by correlating geophysical results with available borehole logs, geological information, trial pits, utility records, monitoring data and other site investigation results.

How We Work

A survey workflow built around the project objective.

Define the target

Review drawings, known ground conditions, project constraints and the engineering question the survey needs to answer.

Select the method

Determine suitable geophysical techniques, survey spacing, coverage and field configuration.

Field acquisition

Carry out systematic data collection with appropriate positioning, field checks and quality control.

Process & interpret

Process survey data and interpret results in the context of geology, site investigation and construction requirements.

Engineering report

Why GEOUE

Geophysics interpreted for engineering, not just mapped.

GEOUE approaches geophysical survey work as part of a broader geotechnical engineering workflow. The objective is not simply to produce colourful profiles, but to provide project teams with technically relevant information that can support investigation planning, construction risk management and engineering decisions.

Engineering Focus

Survey objectives and interpretation are tied directly to the construction or geotechnical problem.

Integrated Capability

Geophysics can be coordinated with soil investigation, instrumentation, monitoring and engineering review.

Singapore Experience

GEOUE’s technical leadership brings prior professional experience from major infrastructure and construction environments in Singapore.

Frequently Asked Questions

Geophysical Survey Singapore — FAQs

What is a geophysical survey used for in construction?

A geophysical survey can provide additional information about subsurface conditions without relying solely on intrusive investigation. Depending on the selected method, it may assist with mapping ground variability, geological interfaces, buried services, anomalous zones or other features relevant to construction planning.

Can geophysical surveys replace boreholes?

Usually not. Geophysical methods provide indirect measurements and are generally most effective when used together with boreholes, trial pits, geological records and other direct investigation data.

Which geophysical survey method should be used?

The appropriate method depends on the target, required investigation depth, expected geology, surface conditions, access restrictions and required resolution. GPR, seismic methods, electrical resistivity and surface-wave methods each respond to different subsurface properties.

Can GPR be used for utility detection in Singapore?

GPR can be useful for locating shallow buried features and utilities where site and ground conditions are suitable. Detection performance varies with soil conductivity, depth, target material, surface conditions and surrounding interference, so it should not be treated as an infallible standalone method.

What information is included in a geophysical survey report?

A typical report may include the survey objective, methodology, equipment and survey configuration, location information, processed results, interpreted profiles or plans, identified anomalies, limitations and recommendations for further investigation where appropriate.
