Earthworks & Drainage — Stirling 5152
Earthworks & Drainage in Stirling, SA 5152
Stirling 5152 is 13.6 km south-east of the Adelaide CBD and inside the 60 km service area. Over shallow loam over ironstone and shale, turning to slick clay in the winter wet, surfaces are regraded to pits and pipes laid with checked fall rather than relying on the ground to take water. Hills drainage handles big winter volumes, springs that appear after rain and gullies. Systems are sized for Hills rainfall and protected from blockage.

Ground conditions at Stirling
Hills drainage handles big winter volumes, springs that appear after rain and gullies. Systems are sized for Hills rainfall and protected from blockage.

What goes wrong on Stirling jobs, and how it is avoided
The problems listed come off this ground and this housing stock rather than a generic list. Each one changes the scope, and each is priced as its own line rather than buried in a rate.
01
Ground: shallow loam over ironstone and shale, turning to slick clay in the winter wet, which decides the trench depth and the soakage.
02
A scope that named one job on the quote and delivered another on site
03
Access or levels discovered after the price was agreed, forcing a variation
04
Work sequenced out of order, so finished surfaces are trafficked by the next trade
05
Drainage left to chance, so the finished work moves or ponds in its first winter
06
A boundary detail agreed verbally with one neighbour and disputed by the other
How it goes
The order the work happens in at Stirling
Drainage is surveyed before it is dug: levels establish where water enters and leaves, the design fixes pits, pipes and grades, trenches are cut, lines laid and tested, pits set, and surfaces regraded and reinstated. At Stirling, access is typically sloped driveways and tight bends — machine selection and delivery logistics decide half the job, so machine size and delivery staging follow that rather than the finished drawing alone.
01
The problem: A waterlogged yard in July — standing water, dying lawn, mud to the back door.
02
Survey: Levels are shot across the site; the water's path (and where it stalls) is mapped.
03
Earthworks: Cut and fill reshapes the site — high ground lowered, hollows filled, falls established.
04
Trenching: Stormwater trenches are cut to grade, falling continuously to the discharge point.
05
Ag-pipe: Slotted ag-pipe wrapped in geofabric is bedded in screened aggregate — the underground drainage web.
06
Pits: Collection pits and channel drains are set at the low points and connected.
07
Backfill: Trenches are backfilled and compacted; surfaces are reinstated over the top.
08
Raining: The same site in the rain — water moving, pooling nowhere, gone in minutes.
Why AOI
One written scope for Stirling
The drainage design and discharge point are agreed before trenches are cut, so the system you pay for is the system that works in winter. The Stirling scope is written against the ground the block actually has: shallow loam over ironstone and shale, turning to slick clay in the winter wet.

Quotes for Stirling
A written quote follows the site visit at Stirling. What moves the number is the cut and fill volumes, the drainage design, the ground and the disposal. The block carries shallow loam over ironstone and shale, turning to slick clay in the winter wet, so ground handling is priced from that rather than from an average.
