Some Deanside lots need piers under the slab where the engineer wants the load carried down past softer or filled ground. We look into each hole before the concrete arrives.
One of our inspectors will call you back. If it is urgent, call 1300 471 805.
Most estate lots here take a waffle raft, but piers turn up under fill, near easements and on sloping corners. When they are specified, their depth is the most important number on the engineering.

Usually less than an hour on a house lot. We need the holes open and safe to look into.
Then there is nothing left to see. Ask your supervisor for the drilling date as soon as it is set.
No. We report what we found against the drawing. The engineer is the one who certifies the footings.
No. Many have a waffle raft with no piers at all. Your engineering drawings will show whether they are needed.
The engineer's footing plan and AS 2870.
Yes. The holes are open and easy to explain, so it is a good stage to attend.
