Electrical, Trenches for sewer, small steps so far.

Well we have AC power wiring to the meter/switchboard position, it may be the wrong cabling but we have something. They have also started the trenches for the sewer connection, excavated the 3m deep hole for the connection to the main line at the rear of the block.
The AC has been provided as approx 10m of single phase supply , the used 16mm sq cables, being setup for a standard domestic 63A supply.  After checking with my sparky, given we have an induction cooktop ( max 42A) and a Pyrolytic Oven (Max 19.4A) , this will exceed the rating of the main circuit breaker.
It pays to check what the MAX Demand  of your home will be and ensure they ( your builder ) are going to order the correct sized mains supply for the home, their sparky should have worked this out for them as per the AS3000 wiring rules.  A few phone calls today to them, finally got on to the estimator "KP" and he was checking to see what has happened.  We gave them the appliance specifications a few times now, last time in Feb when we signed the contracts.  My estimate suggest a 100A single phase or better a 3 Phase supply should be installed.... I can see a variation coming. I don't want future problems with tripping the main circuit breaker every time the oven fires up in clean mode.  Lets see how this one progresses.
