# Concrete Pricing — Quick Reference

## Spec translation

| Site term | Standard notation | Notes |
|-----------|-----------------|-------|
| "40mpa" | 40 MPa | Standard structural strength |
| "80mm slump" | 80mm | Medium-high workability (typical for pump mix) |
| "20mm aggressive" | 20mm aggregate, aggressive | Large aggregate, pump-friendly mix |
| "N32" | 32 MPa | Older spec — convert to MPa for modern plants |

## Typical Sydney readymix rates (ex-GST, 2026 guide)

| Grade | Slump | Aggregate | Day rate/m³ | Night rate/m³ |
|-------|-------|-----------|-------------|---------------|
| 40 MPa | 80mm | 20mm | $220–$265 | +15–25% |

Night shift loading varies by plant. Call to confirm.

## Minimum orders and surcharges

- **Most Sydney plants: minimum 3m³ per load**
- 1.5m³ pour = below minimum → **short load surcharge** applies
  - Typical: $50–$150 extra per load (varies by plant and distance)
- Some plants run small agitator trucks for sub-3m³ pours — ask specifically
- **Fastest path**: call the plant directly. They quote over the phone in 2–3 minutes if you have the specs ready.

## What to have ready when you call

1. Exact specs: 40 MPa | 80mm slump | 20mm aggressive aggregate
2. Volume per pour: 1.5m³
3. Number of pours: 3
4. Site address (for delivery radius)
5. Time window for pour (day vs night)
6. Pump or direct pour?

## Notes on Boral's online quote tool

- Boral's "Request a quote" form is multi-step and requires postcode progression
- The calculator page (`/concrete-calculator`) redirects to a 404 on the new site
- Online self-service doesn't replace a phone call for custom specs
- Boral's main concrete enquiry line is the reliable path for custom mixes

## High-end project estimates (session data, 2026-06-07)

**Specs:** 40MPa | 80mm slump | 20mm aggressive aggregate | night delivery | 3 × 1.5m³ pours = 4.5m³ total

**Per m³ (ex-GST):**
- Base: $220–$265/m³
- Night loading (+20–30%): $336–$416/m³

**Per pour (1.5m³):** $504–$624
**Total (4.5m³):** $1,512–$1,872

**Extras likely:**
- Short load surcharge (1.5m³ under 3m³ min): $80–$150/load × 3 = $240–$450
- Agitator/pump hire: $200–$400/hour
- After-hours dispatch: $50–$150

**Realistic all-in high end: $2,000–$2,800 + GST**

## Pricing strategy for LFCS quotes

- Get 2–3 plant quotes before giving Rock any benchmark
- Concrete is typically 30–50% of total pour cost
- Add 10–15% contingency for short load fees on small pours
- Note: plants in different Sydney suburbs quote differently — a plant closer to the job = cheaper delivery
