Comprehensive Ground Investigation Services in Birmingham and Across the UK

Professional Ground Investigation Services in Birmingham and Across the UK

At Integrated Design & Associates Ltd, our ground investigation typically involves several phases to ensure comprehensive assessment and accurate data collection. Here’s an overview of the different phases:

 

1. Desk Study

A desk study is the initial phase where existing information about the site is collected and analysed. This includes:

• Reviewing Historical Maps and Records: In compliance with the Environment Agency’s guidelines.
• Examining Previous Site Investigation Reports: Following BS 5930:2015, the Code of Practice for Ground Investigations.
• Analysing Geological, Hydrological, and Environmental Data: Using resources like the British Geological Survey.
• Conducting a Risk Assessment: In line with the Contaminated Land (England) Regulations 2006.

 

2. On Site Ground Investigations

This phase involves a physical inspection of the site to gain a preliminary understanding of its conditions. Activities include:

• Visual Inspection of the Landscape and Current Land Use: Ensuring adherence to planning and building regulations.
• Identifying Visible Signs of Ground Instability or Contamination: To comply with the Environmental Protection Act 1990.
• Noting Existing Structures or Features: As per CDM (Construction Design and Management) Regulations 2015.

 

3. Intrusive Investigation

The intrusive investigation is the core phase where detailed subsurface data is collected. Techniques used may include:

• Borehole Drilling: Following BS EN ISO 22475-1 for sampling methods and groundwater measurements.
• Trial Pits: Conducted in accordance with BS 5930:2015.
• Geophysical Surveys: Non-intrusive methods compliant with current industry standards.
• Soil Sampling and Testing: As per BS 1377 for soil testing methodologies.
• Groundwater Monitoring: In line with the Water Resources Act 1991 and BS 6068 for water quality.

 

4. Laboratory Analysis

Collected samples are sent to laboratories for detailed analysis. This phase helps in:

• Determining Soil Classification and Properties: Compliant with BS 1377.
• Identifying Contaminants and Their Concentrations: Following the Environment Agency’s guidelines on contaminated land.
• Evaluating Groundwater Quality and Characteristics: In accordance with BS ISO 5667 for water sampling and monitoring.

 

5. Data Interpretation and Reporting

The final phase involves compiling and interpreting all collected data to produce a comprehensive report. This report typically includes:

• Detailed Descriptions of Ground Conditions: As required by BS 5930.
• Identification of Potential Geotechnical and Environmental Risks: Including compliance with the National Planning Policy Framework (NPPF).
• Recommendations for Foundation Design and Mitigation Measures: Based on Eurocode 7 (BS EN 1997) for geotechnical design.
• Assessment of Compliance with Regulatory Requirements: Ensuring all findings meet UK statutory and regulatory standards.
