Scoped from the civil drawings and the geotechnical report, built in a fixed order.
Where Blackwood drainage fails
Most drainage problems at Blackwood are not the pipe, they are the level: a run laid too flat to move water, a pad graded back toward the house, or discharge pushed onto a neighbour. Every run is fall-tested before backfill, which is the cheapest moment to fix a flat pipe, long before the paving or slab goes down.
Compaction you can show
Pads are compacted in lifts with testing arranged to the level your engineer specifies, and the test results travel with the completion documents. Where the ground is fractured rock close to the surface beneath a thin clay cover, doing it by eye is not good enough and the paperwork is not optional.

The ground under Blackwood
Start with the ground and Blackwood makes more sense: fractured rock close to the surface beneath a thin clay cover. With blocks that are rolling foothill ground with blocks falling away to the south, the cut, the batter and the drainage are decided by the land itself, not by a standard detail copied from another suburb.
Pads and benching at Blackwood
Detention and dispersion are built to the approved plan, including tanks and basins where mains stormwater is not available. On flat or gently rising ground at Blackwood, surfaces are graded to pits and discharge goes to the legal point, not the low corner of the block.
