Why Excavations Near Boundaries Matter
Excavations near neighbouring buildings carry risks such as subsidence or structural damage. The Party Wall etc. Act 1996 regulates excavation work within specific distances and depths to protect adjoining properties.
When a Party Wall Notice Is Required
If excavation work occurs within certain distances from a neighbour’s foundation—usually 3 to 6 metres depending on depth—a Party Wall Notice must be served. This enables the neighbour to assess and respond to potential risks.
Surveyor’s Role During Excavation
Party wall surveyors review excavation plans and assess risks. They recommend protective measures such as shoring, underpinning, or vibration monitoring. Surveyors also conduct condition surveys before excavation starts to document the neighbour’s property state.
Ongoing Monitoring
During excavation, surveyors may conduct regular site visits to ensure protective measures are followed and to detect early signs of damage.
Importance of Early Planning
Building owners should engage surveyors and engineers early in the planning process to design safe excavation methods that comply with the Act.
Communicating with Neighbours
Clear, transparent communication about the excavation scope and timeline helps neighbours understand the process and reduces the risk of disputes.
Ensuring Safe and Compliant Excavation
Following the Party Wall Act’s requirements helps ensure excavation proceeds safely and protects the interests of all parties involved.
