“Recently, your team attended a site in Huddersfield as a subcontractor through one of our suppliers. I was impressed with your team, the supervisor, and the quality of the paperwork”

Basement Impact Assessment (BIA)
Basement extensions are extremely popular right now especially in and around Greater London. A basement impact assessment is a study to check the history of the site, this determines the geology and hydrogeology conditions and the risk of surface water flooding, slope stability problems and any other issues that may arise.
We deliver a quick turnaround on, pre-development basement feasibility assessments, basement impact assessments (for planning) and basement flooding investigations (for existing basements).
Our basement assessment can consist of one or more of the following:
Pre-development basement feasibility assessment
Due diligence summary, outlining the main constraints and potential geotechnical hazards that may be present and whether further assessments are required. Potential options for your basement feasibility and design will be analysed.
Read moreBasement impact assessments (for planning)
Study report to inform you of the risks and hazards to the design methodology of your basement project. This level is required to support a planning application.
Read moreBasement flooding investigation (for existing basements)
Detailed assessment of an existing basement- sources of water ingress that resulted in damage or impairment to the basement functionality. This will identify mitigation measures to enable continued use of the basement.
Read morePhase 1: Preliminary Risk Assessment (PRA)
We conduct a desk study to identify potential contamination risks through historical record reviews, site conditions, and nearby land uses, helping clients understand possible liabilities and guide further investigation.
Read morePhase 2: Site Investigation
Our team performs site investigations, including soil and groundwater sampling, to accurately assess contamination levels, laying the groundwork for effective remediation planning.
