Six documents you need for piling

While it’s important to get the design and installation of the pile foundations right first time, one thing you may not have considered are the documents you need to submit to ensure the foundations are approved by building control.

To help minimise any delays you need to ensure your paperwork is right - here are six documents you’ll need.

Before piling construction

• Geotechnical site investigation report (to below the pile toe)
• Foundation drawings and pile layouts (with pile reference numbers and loadings)
• Calculations to show how the load on each pile was calculated
• Pile design calculation (for vertical, horizontal and heave forces) and a copy of the pile set design

Before further work over the piles

• (a) Confirmation and justification for the proposed number of pile load tests and (b) copies of reports (e.g. static /dynamic / CAPWAP)
• Pile integrity tests and installation logs (with pile numbers referenced to the pile layout drawing)
