Brief the supplier properly
Balance trucks to the loader
Estimate load time, haul time, tip time and return. Enough trucks to keep the excavator loading—no more—gives the lowest cost per cubic metre.
Confirm the tip site
Tip-site hours, material classification (clean fill, VENM, contaminated) and fees vary. Unclassified spoil can be refused.
Check site access and turning
Truck-and-dogs need space to turn and reverse. Confirm road limits, bridge and load restrictions and whether a traffic controller is needed at the gate.
Plan water sources
Water carts need a fill point. Confirm standpipe access, bore water, council permits and fill rates.
For Darwin specifically, tell the supplier the exact site address so they can confirm the depot the machine will come from, the travel or float charge and any NT permit needs.
