However, it turns out there was a more serious issue. Sydney Water had not ticked off the sewer line encasement and general design changes of the house. Without that, no concrete pour. Fortunately Chris verified this was all to happen, but it was not on the inspector's schedule. Given the circumstances, Denis (the inspector) agreed to come on site and check that all was OK. That's him on the left, talking to Chris and Garry. The person with the orange shirt and back to camera is Sam, form Aqua Civil, who did the recent sewer work, and whose company was required to oversee the concrete encasement of the sewer line. And the other person is Ryan, another of Chris' workers.
About this time, the paperwork was completed and the pouring could commence.
This is the sewer line on the western side, with yesterday's water
pumped out. The sandbags are to hold the line in place when the
concrete is poured. Otherwise, the line is capable of rising to
the surface of the concrete, breaking in the process, and requiring
removing the concrete and pipe and doing it all over again.
The sandbags are removed before the concrete sets, but after it
has hardened and can withstand the force the pipe exerts to rise.
The pump line from the concrete pumper out in the street. It's
quite a pump that will pump
wet
concrete that distance, and uphill too.

The above photos show the backhoe with its collection of tools on the left, and specifically the rock breaking tool on the right.
The concrete pumper and one of the crew. The hopper at the back with the open lid
is where the cement truck delivers its load to be pushed
along the pipe running off to the right.
