Phase 2 Site Investigation
We provide robust Phase 2 Site Investigations to characterise soil and groundwater conditions, refine the Conceptual Site Model (CSM) and support safe, compliant development. Our investigations are undertaken in line with BS10175, CLR11 and relevant UK guidance, delivering reliable data to inform risk assessment, remediation and planning decisions.
What this Service Includes
- Design of a site-specific investigation strategy
- Intrusive ground investigation
- Soil, groundwater and ground gas monitoring and sampling
- Laboratory chemical analysis by UKAS-accredited laboratories
- Refinement of the Conceptual Site Model
- Generic and site-specific quantitative risk assessment
- Assessment of risks to human health and controlled waters
- Clear conclusions and recommendations for remediation or further work
Our Approach
Our Phase 2 Site Investigations follow a structured, risk-based methodology aligned with recognised UK guidance and regulatory expectations.
Our approach includes:
- Targeted investigation informed by the preliminary CSM
- Collection of high-quality, representative environmental data
- Transparent interpretation of analytical results
- Clear identification of unacceptable risks, where present
- Practical recommendations to support remediation design and planning approval
We work closely with project teams, contractors and regulators to ensure investigations are efficient, coordinated and proportionate.
Why a Phase 2 Site Investigation is Essential
A well-designed Phase 2 Site Investigation provides the evidence required to confirm whether contamination poses an unacceptable risk and whether remediation is necessary. It supports planning conditions, discharge of regulatory requirements and cost-effective remediation strategies.
By clearly defining site conditions at an early stage, this assessment reduces uncertainty, protects project programmes and prevents unexpected issues during construction.
