Turn a cleared block into a practical starting point for construction with access, levels and material movement planned together.
A good build starts long before the first slab is poured, and Sutherland Shire Site Preparation sets the foundation for everything that follows. We clear, level and shape the site so your builder gets a safe, workable platform.
Tell us about your block, the proposed build and any plans or surveys you hold. We scope the work to suit access, drainage, soil conditions and the sequence your trades need, so nothing is rushed or repeated.
From Menai and Engadine to Sylvania, Gymea and Cronulla, sloping and bushy blocks are common. Local experience with Shire soils, rock and access helps keep your project on programme and on budget.
Explore the scope ↓We remove vegetation, debris and uneven ground, then shape the site to the required levels, giving your builder a stable and workable platform before construction begins, saving you time later. Set-out pegs and survey marks are protected throughout the work.
Site preparation accounts for water flow, soil type and rock, along with any old fill that needs removing and replacing, so the ground performs as intended and your build is protected from future movement, pooling or erosion problems later on.
Work is planned around your builder, concreter and plumber, ensuring each trade can start on time and the site remains safe, accessible and organised throughout the project from day one. Clear access for deliveries, trucks and machinery is maintained daily.
Site preparation is a sequence. Doing the steps out of order is how you end up re-excavating a platform you just finished.
Lodge Dial Before You Dig and confirm the approved plans, conditions and any tree or heritage constraints before a machine starts. Private pool plumbing, irrigation and stormwater lines never appear on those plans, so ask the owner what is buried.
Sediment fencing, a stabilised entry and inlet protection go in first so mud stays on the block. The Blue Book is the standard reference and sediment reaching stormwater is an offence. Check and repair the controls after every heavy rain.
The builder or surveyor pegs the footprint and benchmark levels from the plans. Work to their pegs rather than guessing, protect them from machine traffic, and ask who re-checks them after stripping, because pegs are easily disturbed during bulk earthworks.
Topsoil and organic matter are stripped and stockpiled, then the pad is cut or filled to formation level. Organic material should not be buried under the building area because it rots and settles, leaving cracked slabs and uneven floors later.
Fill goes down in thin layers and is compacted, with moisture adjusted so it binds properly. Where engineered fill is required, a testing provider checks it to AS 3798 supervision levels and records results the certifier and engineer will want.
The pad is trimmed to the agreed levels with access left clear for the footing or slab crew. Walk it with the builder before the first trench opens, and note any soft spots, rock or levels that still need attention.
The DA or CDC conditions often set work hours, tree protection and sediment control requirements. The contractor needs to see them, not hear them summarised, because a missed condition can lead to a stop-work notice or a costly change later.
A site survey with contours, boundaries and a finished floor level lets the pad be shaped to the design. Without it, cut and fill quantities are guesses, and the quote may change once the real levels are known on site.
It tells you about fill, rock depth, groundwater and site class. Sloping Shire blocks and filled ground are where surprises usually sit, and the report helps the contractor choose suitable machines and realistically price rock, groundwater or soft ground conditions.
Gate widths, street width, overhead wires and where trucks can stand all affect machine size and how spoil gets away. Note steep driveways, narrow cul-de-sacs and parking restrictions, since they decide whether a small excavator or a larger machine fits.
Existing fences, retaining walls and cracks next door are worth recording before heavy machinery arrives. Dated photos or a dilapidation report give everyone a clear, shared starting point if a neighbour later raises concerns about damage from vibration or excavation.
Uncompacted or untested fill under a slab can settle, cracking floors and footings later. Ask up front whether the design needs engineered fill and who will test it, because retesting or removing fill after the slab is poured is impractical.
Raising or lowering ground near a boundary can push stormwater onto a neighbour. Check falls against the approved drainage plan, keep surface water flowing to pits or the street, and talk to the builder before changing any approved finished level.
Stockpile topsoil separately so it can be reused for landscaping rather than being trucked away and bought back. Mixed into structural fill, topsoil also weakens the pad, because organic material compresses, holds water and slowly breaks down under the slab.
Wet ground beside rivers or canals can bog a machine and disturb the subgrade. Planning ground protection or dry-weather windows avoids it, as does choosing lighter tracked plant and keeping trucks on firm access tracks, existing hardstand or the street.
An old sewer branch or buried pool line is often not on any plan. Hand-dig or pothole where records are unclear, and stop if an unexpected pipe or cable appears, so a plumber or the network operator can identify it.
A pad that sits partly on sandstone and partly on fill can move unevenly, because the two support loads differently. It is common on sloping Shire blocks. Tell the engineer where rock and fill meet, so the footing design can deal with it.
A strong build begins with well-prepared ground, and our site preparation experts get the foundations of your project right. We clear, level and shape your block to the required levels, accounting for drainage, soil type and rock before the first trade arrives. Clear planning means your builder, concreter and plumber can start on time without waiting for the site to be ready. Skilled operators work accurately, keeping the site safe throughout. With local knowledge of Sutherland Shire sloping blocks, sandstone and access challenges, we avoid delays and rework, delivering a stable, workable platform that gives your project a confident start.

Ask us about your project ↗Site preparation shapes the ground for construction: stripping, levels, cut and fill, compaction. A site clean is the removal of debris and surplus material, usually near the end of or between stages.
If levels matter to the design, which they usually do, the builder or surveyor should set out the pad. Ask who provides the pegs before you book machines.
Sometimes, if it is clean, suitable material and the design allows. Soil leaving a site may need classification before a receiving site accepts it, so ask about both directions.
Where engineered fill is specified, testing by a geotechnical provider is typically required. Your engineer or certifier will say what applies.
