Are bored piers inspected before being filled with concrete?

Yes, typically — bored pier holes are inspected before filling to confirm depth, diameter, and ground conditions match what the engineering design expects, since this is the only genuine opportunity to verify these details before they’re permanently covered by concrete.

This inspection can be carried out by the supervising engineer or building surveyor, confirming the pier as excavated is genuinely suitable for the design before concrete is poured.

Skipping this step risks a pier that doesn’t actually match the design intent going undetected — this is exactly why it’s a standard, non-negotiable part of proper bored pier construction.
