Where the engineer has specified piers, we check the holes and the steel after drilling and before concrete fills them for good.
One of our inspectors will call you back. If it is urgent, call 1300 471 805.
The Werribee Plains can put weathered basalt within a metre of the surface, and piers on Mambourin lots are drilled through reactive clay towards it. Whether each pier reached the depth and bearing the engineer asked for can only be seen now.

Depth, diameter, cage position, cover and how clean the base is, each measured against the engineer's pier schedule.
The engineer adds them where the soil report shows deep fill, soft ground or rock at varying depth. Not every lot gets them.
Usually less than an hour for a standard house.
No. Once filled with concrete, depth and steel placement cannot be seen again.
The engineer or the building surveyor's inspection does. Our report records what we saw against the drawings.
The report records the measured depth beside the specified depth so the builder can drill further or refer it to the engineer.
