At Integrated Design & Associates Ltd, our site & 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 in Lichfield
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 in Lichfield 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.
