Use this guidance to check what may be needed before you submit information.
If the wording on your planning condition, tender request or site constraint is unclear, send it to EnviroSolution and we can advise which report, survey or assessment is likely to be relevant.
Before You Instruct a Phase 2 Ground Investigation
A Phase 2 Ground Investigation is typically required to support planning conditions or confirm risks identified during a Phase 1 Desktop Study. Before commissioning works, gather all relevant documents including planning decision notices, previous reports and site history. This ensures the investigation is properly scoped and avoids unnecessary delays.
Key Considerations for Site Works
Access, services, boundaries and working restrictions should be confirmed before fieldwork begins. Consider whether additional elements such as groundwater monitoring, gas monitoring or geotechnical input are required. Aligning these early prevents the need for repeat visits and reduces overall project cost.
What the Report Needs to Deliver
A compliant Phase 2 report should clearly define the conceptual site model, present investigation results and provide a robust risk assessment. Where planning is involved, the conclusions must directly address the wording of the planning condition to support discharge.
