| **Total direct** | **295.3** | **$28,063** | **$6,080** | **$34,143** |

### Loaded totals (×1.3225)

| Trade | Labour loaded | Materials loaded | Trade loaded |
|---|---|---|---|
| Formwork | $5,697 | $4,927 | $10,624 |
| Steel fix | $3,335 | $825 | $4,160 |
| Concrete place+finish | $17,628 | $278 | $17,906 |
| Curing | $2,010 | $1,912 | $3,922 |
| Joints | $2,287 | $99 | $2,386 |
| Site overhead | $6,156 | — | $6,156 |
| **Total loaded ex GST** | **$37,113** | **$8,041** | **$45,154** |

## Headline numbers

- **Total ex GST direct: $34,143**
- **Total ex GST loaded (×1.3225): $45,154**
- Loaded uplift over direct: $11,011 (32.25% — matches multiplier)
- Total labour MH: ~295 hrs
- Sanity-check vs Bid Prep §7 magnitude estimate ($48,140 loaded): worker take-off comes in **6% below** §7 estimate. Difference within expected refinement band; §7 was conservative magnitude pre-line-itemisation.

## Variance sources (worker estimate vs sanity §7)

| Line | Worker estimate | §7 estimate | Delta | Reason |
|---|---|---|---|---|
| Total labour direct | $28,063 (295 MH) | $30,400 (320 MH) | −8% | Productivity rates refined per line; less padding |
| Total materials direct | $6,080 | $6,000 | +1% | Aligned |
| Total loaded | $45,154 | $48,140 | −6% | Composite of above |

## Quantity confidence + RFI gate

**All quantities provisional ±20-30% pending architectural setout RFI** (RFI #1 in Bid Prep F3 + Q-G4). Lines most sensitive to architectural confirmation:
- 150mm slab area (currently 169 m² provisional)
- 125mm pathway extent (currently 120 m² provisional)
- Seating terrace footprint (currently 25 m² provisional)
- Joint lengths (derive from slab perimeters)
- Trimmer-bar count at openings (currently 6 provisional)

If architectural plan reduces total slab area by 30%, total drops ~$10K loaded. If increases by 30%, total rises ~$10K loaded.

## RFIs gating final submission

1. **Architectural setout drawings** — HIGH (quantity ±30% band)
2. **Concrete grade for 125mm pathway** — LOW $ (HC pays supply premium)
3. **Pavement spec template carry-over (St Ives reference)** — NIL $ (designer confirmation only)
4. **Working hours + Saturday allowance** — LOW (variation rate if Saturday)
5. **Programme dates + continuous run** — MEDIUM (broken programme = variation rate per std excl 7)
6. **Shelter shop drawings (post footings)** — LOW–MEDIUM (additional pad footings if confirmed)
7. **Stormwater drainage drawings** — LOW (slab penetrations + trimmer count)
8. **Piering** — MEDIUM (scope expansion via variation if confirmed)

## Flag items for Rocky at sanity-check

| Q-D2 | Saw-cut 24-hr window risk for late-afternoon pours | Standard pricing; Rocky may add explicit off-hours saw-cut variation line |
| Q-E | Productivity reductions: DEB1 +30%, existing-slab +15-20%, stepped SF1 +10-15% | Confirm calibration at sanity-check |
| Q-F4 | Format choice — both lump-sum + BoQ-response | Confirm at sanity-check or RFQ receipt |
| §7 variance | Worker total 6% below §7 magnitude — within refinement band | Confirm acceptable |

## Worker layered exclusions feed-back to revision-2

Following carve-outs derived from this take-off; **add to exclusions-2627.md revision 2**:

- **A7 corrected:** cure period 7 days (not 14)
- **A10 (NEW):** Existing-slab interface productivity reduction 15-20% built into per-line rates; LFCS not responsible for unforeseen interface conditions beyond drawings rev D
- **A11 (NEW):** DEB1 deep-edge-beam productivity reduction 30% built into rate; LFCS not responsible for delays from DEB1 prop-removal cylinder-test timing per S000 concrete note 9
- **A12 (NEW):** Stepped SF1 seating terrace productivity reduction 10-15% built into rate
- **Detailed Excl 53 (NEW):** Quantities provisional ±20-30% subject to receipt of architectural setout drawings; final price subject to confirmed quantities
- **Detailed Excl 54 (NEW):** Density coring 75-100mm Ø within 2 days per pavement spec §14.2.5 — destructive testing + core repair cost via HC, not LFCS
- **Detailed Excl 55 (NEW):** Late-afternoon pour saw-cut window: if 24-hr SJ saw-cut requires off-hours work per pavement spec §11.3.6, variation at LFCS Rate Card V1.7 night/weekend loading (8-hr minimum charge)
