Geotechnical Investigation

Is the study conducted to assess soil and rock properties, foundation conditions, and stability for infrastructure projects through utilizing industry-standard methods such as Standard Penetration Test (SPT), Cone Penetration Test (CPT), and sonic drilling, along with traditional techniques like trial pits.

STANDARDS

BS 5930:2015 - Code of Practice for Site Investigations
Unified Soil Classification System (USCS)

ISO 14688 - Geotechnical Investigation and Testing

ASTM D1586 - Standard Penetration Test (SPT) of Soils.

ASTM D2488 - Standard Practice for Description and Identification of Soils.

Geophysical Surveys

This survey involves determination of the position, in three dimensions of natural and
man-made features on the surface of the Earth. These features are then represented in analogue
form as a contoured map, plan or chart, or in digital form such as a digital ground model (DGM).

Hydrogeological Studies

These studies involve thorough analysis of groundwater flow, aquifer characteristics, and water quality to inform sustainable water resource management and infrastructure design. By utilizing methods such as pumping tests, tracer studies, and aquifer testing to address challenges related to water availability, contamination, and sustainable management practices.

Seismic Hazard Analysis

Is the evaluation of seismic risks and ground motion parameters to ensure structural resilience and safety in seismic-prone regions through utilizing probabilistic seismic hazard assessment (PSHA), ground motion modeling, and site response analysis to address challenges related to seismic design, risk mitigation, and structural safety.

Geochemical Analysis

Conducting detailed examination of soil and water chemistry to identify contamination sources, assess environmental risks, and support remediation strategies. Utilizing techniques such as X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS), and chromatography to address challenges related to pollution assessment, resource management, and environmental protection.

Geological Surveys

Is systematically mapping and characterization of geological formations to understand terrain properties, geological hazards, and resource potential through utilizing field mapping, remote sensing, and GIS analysis to address challenges such as resource exploration, hazard assessment, and land-use planning.
