In Fundamental Integrated Site Appraisal Services Limited (FISAS) geotechnical site appraisal is a systematic assessment of the geological and geophysical properties and conditions of the soils of a site to determine its suitability for a specific project or development. It involves a thorough investigation of the site’s geology, soil, and groundwater conditions to identify potential foundation hazards, risks, and constraints to sustainability of the project.
A typical geotechnical site appraisal includes:
1. Site reconnaissance and desk study
2. Geotechnical mapping and soil sampling
3. Laboratory testing of soil and rock samples
4. In-situ testing (e.g., boreholes, trial pits, geophysical surveys)
5. Data analysis and interpretation
6. Reporting and recommendations
The site appraisal aims to provide a comprehensive understanding of the geotechnical conditions at site including:
– Soil physics and rock properties
– Groundwater condition, levels and flow
– Stability and settlement potential of soil
– Earthquake and landslide risks
– Environmental hazards (e.g., contamination, saturation and erosion)
The results of the Site appraisal in FISAS inform site owner decisions on:
– Selection and planning of project Site
– Foundation design and construction
– Earthwork and excavation management
– Drainage and water management
– Risk mitigation and amelioration
Geotechnical site appraisals in FISAS offer integrated solutions to site issues and are crucial in various project development programmes, including construction, infrastructure development, mining, and environmental assessments.
