Basement IMpact Assessment (BIA)

What Is a Basement Impact Assessment?

A Basement Impact Assessment is a detailed evaluation that determines the potential impacts of basement construction on surrounding properties, soil stability, and local water tables. It includes essential elements such as:

• Geotechnical Assessment: Evaluates soil conditions and ground stability for safe excavation.

• Hydrogeological Study: Assesses water tables and drainage requirements to mitigate future flooding risks.

• Structural Risk Analysis: Analyses load-bearing requirements and assesses impact on neighbouring structures.

Required for Planning Permission in Specific Boroughs

In several London boroughs, a Basement Impact Assessment is mandatory for securing planning permission. This assessment demonstrates compliance with local regulations and provides assurance to both property owners and planning authorities that the project will be safe and sustainable.
