Geophysical methods in civil engineering provide valuable information about the subsurface structures and properties, which are used to improve design and construction, reduce risks, and optimize project costs.
Construction planning and excavation
– detect buried objects, such as utilities, pipes, and rebar
– detect subsurface anomalies, such as sinkholes or underground voids
– detect and map subsurface magnetic anomalies, such as buried metal objects, UXOs or geological structures
– detect buried infrastructure, such as pipelines and tanks, which aid field operations management and minimize the risk of accidents
Engineering design and foundation
– compressional and shear wave subsurface velocity profile
– VS30 calculation to classify soil types for earthquake engineering
– depth and properties of subsurface layers
– slope and embarkment stability analysis
– subsurface structure mapping and hazard identification: faults, folds, geological model
– 3D images of the subsurface structure
– detect and map subsurface material features, properties and dimensions
Infrastructure assessment and monitoring
– concrete structure evaluation: crack detection, void mapping, structural defect identification for bridges, buildings, tunnels
– concrete and asphalt pavements thickness assessment to determine the state of roads, runways, and highways
Geophysical methods can be used for a wide range of environmental applications, such as groundwater exploration, contaminant mapping, and landfill characterization.
Groundwater exploration
– non-invasive investigation of the 3D subsurface properties of soils, sediments, and rocks to characterize potential groundwater reservoirs;
– geophysical mapping of the bedrock, fractures, and other subsurface structures that may affect groundwater flow
– assess soil stability to evaluate landslide risk and contamination paths of groundwater
– investigating the subsurface electrical properties of soils and rocks, to identify groundwater resources
Contaminant mapping
– identify and map surface and subsurface pollutants and their spatial distribution
– identify the presence of subsurface features such as buried objects, voids, and fractures to determine pollutant sources and travel pathways
– identify the presence of buried materials that can cause potential hazards
Geohazard identification and risk assessment
– determine the P and S wave velocity profiles of the subsurface, to assess the seismic hazard and terrain stability
– evaluate and model the underground geological features to evaluate slope stability, terrain stiffness, seismic hazard and landslide risks
Geophysical techniques serve as potent means for the non-invasive detection and examination of archaeological sites. Employing geophysical investigations in archaeology represents an optimal approach to streamline excavations, reduce project expenses, and direct efforts towards areas with the highest potential.
Site identification and mapping
– locate buried foundations, walls, and structures, map burial sites and identify subsurface features.
– identify changes in soil composition that may indicate anthropic activities
– locate metal objects, such as artifacts and coins
– locate voids, such as underground chambers and tombs
Geophysical methods play a vital role in the exploration, development, and production of oil and gas resources. The selection of the appropriate method(s) depends on the geology of the target area, the size and depth of the reservoir, and the exploration objectives.
Mapping of geological structures
– detect and map magnetic minerals associated with hydrocarbon-bearing rocks, such as iron-rich minerals in sedimentary basins
– monitor subsurface injection operations, like CO2 sequestration, by imaging the subsurface and identifying changes in fluid distribution and subsurface deformation (magnetometry)
– detect changes in subsurface dielectric properties, such as the presence of hydrocarbon reservoirs, by imaging the subsurface and identifying areas of high acoustic impedance contrast (GPR)
Seismic supervision and planning
– client representative services from negotiation of contract to final deliverables, from terms of contract, project planning, field operations supervision and data QC, to final deliverable evaluation
– determine the survey parameters, such as the survey area, line spacing, receiver and source configurations, and environmental considerations
– monitoring the data acquisition in real time and ensuring that the quality of the data meets the specified standards
– ensuring that the survey operations comply with health, safety, and environmental regulations and standards, as well as contractually agreed acquisition terms
Well permitting
– locate and negotiate with the landowners on behalf of the Client to secure the future location of the well
– obtaining all relevant permits and approvals for the Building Permit
– elaborating technical documentation for the well pad and road building
– obtaining the Environmental approval
