## Quantity table — provisional

**Critical caveat:** dimensioned architectural plan NOT supplied. All m/m²/m³ values below derived from visual scaling of S50/S100/S200 against grid spacing assumed at 3m typical. Subject to ±20–30% revision once architectural setout received.

### Formwork (S+I+S)

| Element | Qty | Unit | Source | Productivity assumption |
|---|---|---|---|---|
| SF1 perimeter strip footing forms (top edge gridline 1-2 + side returns @ A + F) | 30 | lin m | S100 | 2 sides × 0.5 deep = 30 m² form face |
| SF2 internal strip footing forms (gridline 2 between C-E) | 10 | lin m | S100 | 2 sides × 0.5 deep = 10 m² form face |
| SF1 stepped-lift forms — seating terrace (3 lifts visible, ~6m run each) | 18 | lin m | S51 | stepped: avg ~0.7m form face per lin m → ~25 m² form face (extra labour for stepping) |
| DEB1 drop edge beam forms (top edge gridline 1-2; 1200 deep × 300 thick) | 13 | lin m | S200 | 1.2m face one side + 0.3m soffit + ends; ~22 m² form face + heavy props |
| 150mm internal slab edge formwork (where DEB1 + existing wall not forming) | 30 | lin m | S200 | 0.15 deep edge form ~5 m² form face |
| 125mm pathway slab edge formwork (perimeter of pathway, less DEB1 length) | 80 | lin m | S200 | 0.125 deep ~10 m² form face |
| Seating terrace concrete formwork (150 slab + step + nosing per S51) | 25 | m² | S51 | stepped slab forms; complex |
| Riser formwork (S200 "concrete riser" at local removal of existing wall) | 1 | item | S200 | small bespoke form |
| Total form face | ~140 | m² | combined | productivity 4–6 m²/manhour set, 12–15 m²/manhour strip |

### Steel fix

| Element | Qty | Unit | Source | Notes |
|---|---|---|---|---|
| SL82 mesh top + bottom — 150mm slab | 169 × 2 = 338 | m² fixed | S200 | A1 cover 30/30/30; plastic chairs (no metal/wood/agg) per spec §8.2 |

### Concrete place + finish

| Element | Qty | Unit | Source | Productivity |
|---|---|---|---|---|
| 150mm slab on ground (internal, function room footprint provisional 13.0 × 13.0 = 169 m²) | 25.4 | m³ | S200 | ~160 m²/day pavement productivity (Assumption A8); function room ~1 day place + finish |
| 125mm pathway slab (external; provisional perimeter strip ~120 m²) | 15.0 | m³ | S200 | ~160 m²/day pavement productivity |
| DEB1 drop edge beam (13 lin m × 1.2 deep × 0.3 thick) | 4.7 | m³ | S200 | beam place: ~10 m³/day for stepped/deep beam |
| SF1 strip footings (30 lin m × 0.45 × 0.5) | 6.8 | m³ | S100 | footing place ~20 m³/day |

### Curing

| Element | Qty | Unit | Source | Method |
|---|---|---|---|---|
| Polythene + hessian — 150mm slab | 169 | m² | S200 | pavement spec §10.3.1 hessian moist; min 7 days per spec §10.1.1 (NOT 14 — earlier exclusions skeleton A7 to be revised) |
| Polythene + hessian — 125mm pathway | 120 | m² | S200 | ditto |
| Polythene + hessian — seating terrace 150mm slabs | 25 | m² | S51 | ditto |
| Polythene + hessian — DEB1 + footings + risers + stairs (approx surface area ~30 m²) | 30 | m² | S100/S200/S201 | ditto |
| **Total curing area** | **~344** | **m²** | combined | hessian 2× turn + maintenance over 7-day cure period |

### Joints

| Joint type | Qty | Unit | Source | Method |
|---|---|---|---|---|
| Sawn control joints (SJ) — max 4m spacing | ~60 | lin m | S200 (visible SJ symbols around perimeter + internal at re-entrant corners) | provisional; 4m grid on ~169 + 120 m² + saw within 24 hrs of pour per spec §11.3 |
| Keyed construction joints (KJ) — max 10m spacing | ~25 | lin m | S200 | painted bitumen first cast face per typ detail |
| Expansion joints — max 20m spacing | ~10 | lin m | S200 | pre-formed filler per spec §11.2 |
| Isolation joints (IJ) — 10mm polyethylene | ~80 | lin m | S200 | between walls/columns + new slab — material supplied by HC per envelope item 24, LFCS installs |
| Joint sealant + backing rod | ~95 | lin m | S200 detail | sealant material by HC; LFCS installs sealer flush per spec §11.6.2 |

## Joint productivity note

Joint forming + cutting is labour-intensive vs lineal-metre rate-card. Saw cut MUST be within 24 hrs of pour per S200 SJ detail + spec §11.3.6 — places NIGHT or weekend saw-cut risk if pour late afternoon. Cancellation premium per Rate Card V1.7 may apply if HC recall LFCS off-hours. Flag for posture grill Q-D2.

## Drop edge beam DEB1 productivity flag

DEB1 at 1200mm max deep × 300mm thick + 13 lin m run + N12-300 horiz at base + 4F12 TM at top + N12-200 horiz reinforcement is a **deeper-than-standard slab edge** — productivity reduced vs typical 300–400 deep edge beam:
- Forms: heavy props + waling; slower set + strip than standard
- Reo: deeper cage with multiple bar layers; slower fix
- Place: pump-only feasible; tremie + vibrator at base
- Strip: 24-hour minimum per spec §6.5.1, 28-day OR 14-day-with-cylinder-test for prop removal per S000 concrete note 9
- **Productivity reduction: ~30% vs standard edge-beam baseline. Built into rate.**

## Existing-slab interface productivity flag

Tooth slab + tooth stair into existing slab/brick wall (Section 1 + 2 of S201) + drilled-and-epoxied dowels + locally removed existing wall to accommodate concrete riser are all interfaces with existing structure. Productivity reduced vs greenfield slab:
- Drill + epoxy dowels: ~3 min/dowel (drill 16mm × 150mm + dust extract + 2-part epoxy + insert + clean) × ~50 dowels = ~2.5 hrs incl. setup + curing wait time
- Toothing detail (S200 typ toothing detail): saw-cut + chip + clean existing slab face + waterproof bond agent + new pour. Slow productivity.
- Wall demolition coordination — NOT LFCS but LFCS has wait/standby time
- **Productivity reduction: ~15–20% vs greenfield first-pass. Built into rate.**

## Open RFIs (from take-off)

1. **Architectural setout drawings** — figured dimensions of function room footprint + pathway extent + seating terrace extent. Primary RFI; quantity confidence ±20–30% until received.
2. **Concrete grade for 125mm pathway slab** — drawings rev D S200 concrete quality table says 32 MPa; pavement spec Table 1 says 35 MPa compressive + 4.5 MPa flexural. Spec wins by precedence for pavement-classified element. RFI to designer to confirm intent.
3. **Pavement spec § 1 Introduction** — references "St Ives Showgrounds proposed carpark development" — template carry-over from another project. Confirm spec applies to Strathfield Parks Airey Park as intended.
4. **Piering** — S100 + S200 note "PIERING MAY BE REQUIRED. ENGINEER TO CONFIRM DURING CONSTRUCTION". If piering confirmed, scope expansion via variation. Provisional NIL in first-pass.
5. **Shelter shop drawings (post footings)** — S51 refers to shelter shop drawings for post footings — not in inbound set. Additional pad footings under shelter pavilion likely. Provisional NIL until received.
6. **Stormwater drainage drawings** — S200 refers to drainage drawings for pump well + sump locations. Sumps + waterstops NOT LFCS but trimmer bars + slab penetrations affect take-off. Provisional NIL.
7. **Geotech report S2348_GL_02_Rev0** — referenced but NOT in inbound set. Bearing capacity assumed 210 kPa stiff clay AS2870 H1. Geotech reading NOT required for take-off but flagged for completeness.
8. **Curing duration discrepancy** — exclusions skeleton A7 says 14-day cure; pavement spec §10.1.1 says minimum 7 days. Reduce A7 to 7-day cure in revised exclusions list. Cure cost reflects 7-day not 14.
9. **Number of openings + slab penetrations** — TR (2N12-1200 long trimmer bars) symbol on S200 indicates openings, but exact count + size depends on architectural penetration schedule. Provisional 6 openings.
10. **Cast-in services + conduits >25mm Ø** — S000 concrete note 7 requires spacing; per envelope item 22 cast-in items supplied by HC. RFI to confirm M+E + Hydraulics drawings supply count + locations.
