Geoss Guidelines On Local Practices For Pile Foundation Design And Construction Verified

8. Documentation and Approval (BCA/GEOSS)

Pile design report: Must include geotechnical model, pile capacities, settlement analysis, negative skin friction calculation, and rock socket verification.

Construction record: For each pile – driving log (driven piles), boring log (bored piles), concrete pour record, test results.

As-built drawings: Pile locations with deviations clearly shown.

Jacked Foundation Piles: Guidelines on the installation of jacked piles, including draft recommendations for ground movement control.

Necessity of Verification: Deep foundations are required when surface soils are weak or unstable. GEOSS guidelines mandate that the design must be verified against actual ground conditions during construction to ensure safety and serviceability.

How Local Practices Are Verified

In cases where parameters are not verified by a load test, designers must adopt conservative recommended values for bored piles as specified in the Joint BCA/IES/ACES/GeoSS Circular 2. Design Methodology (Eurocode 7)
