Concrete Cost Guide Bunbury

Compare written scopes, not isolated metre rates.

What the job involves

Mobilisation, demolition, access, pumping, base preparation, reinforcement and decorative finishing can outweigh raw concrete volume on residential jobs.

Decisions that shape the scope

Preparation

Excavation, disposal, base and compaction.

Structure

Thickness, reinforcement, joints and edges.

Placement

Supply, access, pumping, labour and curing.

Finish

Texture, colour, exposure, sealing and clean-up.

Local planning point

What to check in this market

Include verge approvals and crossover work where relevant. A broad online price is not a property-specific offer.

Compare like with like

Ask each responding provider to put the proposed scope, assumptions, exclusions and responsibilities in writing. A lower figure is not a saving if it omits preparation, access, disposal, approvals or completion work that another quote includes.

For a Greater Bunbury enquiry, send the actual site address with the measured footprint. State whether the estimate includes a private driveway, a shed slab or work at the public frontage. Ask the responding provider to confirm design and approval responsibilities for that property, rather than treating a bag yield or national driveway rate as a local specification. The Bunbury driveway page helps describe access and finish choices for the enquiry. Check the local access scope.

Enter your measurements or observations, then calculate. This is a planning aid; confirm the proposed work on site.

100 mm is a private light-vehicle example, not a design. Changing project clears thickness.

Method: area = length × width; volume = area × thickness/1000; allowance volume = volume × (1 + allowance/100). Default 8% allowance and rounding up to 0.1 m³ are assumptions, adjust to suit.

Example: 6 × 4 m at 100 mm, 8% = 24 m², 2.4 m³, 2.592 m³ with allowance; indicative order 2.6 m³. Ask a supplier about delivered concrete.

Cement Australia Concrete Mix: 110 × 20 kg bags/m³, shown only at ≤1.0 m³ (our rounding, adjust to suit). ARC: rough one-layer sheets = area/12.4, rounded up, 6 × 2.4 m sheets including standard laps; not reinforcement design. CCAA minima: foot traffic 75 mm; vehicles under 3 tonnes 100 mm; 3–10 tonnes 150 mm. Not slab/crossing specifications.
