## Pavement specification — P171342-SP-001-0 rev 0 (15 sections + 4 prelim pages)

| § | Title | LFCS-relevant | Notes |
|---|---|---|---|
| 1 | Introduction | Flag (template carry-over) | "Construction of the joint reinforced concrete pavement base for the pedestrian footpaths at **St Ives Showgrounds proposed carpark development**" — text references St Ives Showgrounds carpark. Different project. Template doc reused. RFI to designer requested to confirm intent. |
| 3 | Referenced Documents | Yes | AS1379, AS1478.1, AS2758.1, AS2870, AS3582 (parts 1+2+3), AS3600, AS3799 (curing compounds), AS3972, AS/NZS 3679.1, AS/NZS 4671. ASTM C171-07 sheet curing materials. |
| 4 | Materials | Yes (key conflict) | **TABLE 1: Pavement element "Base" → Strength Compressive 35 MPa, Flexural 4.5 MPa**, slump 80, max agg 20, max sublot 30m³ or one day's pour. Cement type, min cement content, max SCM, max w/c — all "to be nominated by Contractor." **Conflicts with structural drawings rev D S100/S200 concrete quality table → 32 MPa for slab on ground.** RFI required: which strength applies to 125mm pathway slab? Drawings call it slab-on-ground (32MPa); spec calls it pavement base (35MPa flexural-rated). Spec wins for pavement base by precedence if drawings ambiguous. Wax-based curing compounds NOT recommended (slippery); curing compound must comply AS3799 + tested. |
| 5 | Equipment | Indirect | LFCS provides own equipment. |
| 6 | Formwork | Yes | Steel or seasoned-dressed-timber planks with metal angle/channel along top edge, full base depth, 3mm/3m straightedge tolerance, 3mm vertical alignment from required level, 6mm form-face tolerance from alignment, stake max 1.5m apart. Form-removal 24 hrs minimum. Subbase 6.4 maintained smooth/compacted/dampened. |
| 8 | Placing + fixing reinforcement | Yes | AS3600 laps; chairs/spacers/stools metal/concrete/plastic only (no wood/aggregate/brick); placing tolerances per AS3600. |
| 9 | Placing, compacting + finishing | Yes (productivity-critical) | 24 hrs notice prior to pour. Concrete max 90 min from batching; truck temp 5–35°C; ambient <10°C or >30°C requires §13 precautions. Slump tolerance ±15mm at 80mm specified. Re-tempering only with approval per a–g protocol. **Min place rate 20 m³/hr** + plant/crew capable. >30 min interval = transverse construction joint. Compaction by internal vibrator + vibrating-beam screed (>200mm thick = vibrator first). Min 1 vibrator per 7 m³/hr placed + 1 standby. Float-screed-test 3m straightedge. Trowel (powered, after surface hard enough); broom texture across full width 500mm broom. |
| 10 | Curing | Yes | **Min 7-day cure** (NOT 14 — earlier assumption A7 in exclusions skeleton overstates; reduced to 7 days here). Initial wet curing within 3 hrs of finish OR strip. Methods: hessian moist + ponding, sprayed membrane (AS3799), or impermeable sheet (ASTM C171). Hessian must overlap ≥150mm. Sheet curing must overlap ≥500mm + tied/weighted. |
| 11 | Joints | Yes | All joint locations per drawings. Isolation/expansion: pre-formed filler, sealed top + edges, dowels per Cl 11.5. Contraction: weakened-plane or key, tooled OR sawn (3-5mm wide × ¼–⅓ depth) — saw-cut timing varies by ambient. Construction joints: at end of day or 30-min interruption. Dowels straight + parallel + tolerance ±10mm both directions; bonded-in or PVC sleeve to first-placed; 300mm clearance from transverse joint for round dowels (150mm for plate dowels). Joint sealant: clean groove, sealer flush or ≤5mm below surface. |
| 12 | Protection | Yes | 7 days minimum traffic exclusion; mats/plates/timbers if construction equipment crossing earlier; cleaning + barrier replacement same day. |
| 13 | Adverse weather | Yes | Hot weather (>30°C ambient, >35°C concrete): sprinkle forms/reo/subbase, shade aggregates, cool mix water, mid-day avoidance, aliphatic alcohol spray. **No concrete in rain; protect <24-hr concrete with waterproof covers.** |
| 14 | Testing + acceptance | Indirect | LFCS makes cylinders + delivers, mould 2 pairs cylinders per sublot (1 pair 7-day + 1 pair 28-day) per AS1012.7; **flexural beam test** per sublot (AS1012.1, RMS T304, AS1012.8 cure) — flexural testing rare for park pavement; **NATA lab cost via HC** per envelope item 28. Density check via cores 75–100mm Ø within 2 days — **destruct test invasive; HC/owner pays for core repair**, LFCS not responsible. Rejection: porosity, displaced reo, displaced cast-ins. |
| 15 | Construction tolerances | Yes | Surface flatness ≤5mm/3m. Thickness ±5mm tolerance from specified, else cores on 3m grid until conforming, replace deficient panels. Surface grinding limit 10% of panel area or 3% of total base area before remove-and-replace mandate. |

## Sheets NOT in this drawing set (RFIs)

- Architectural plans + setout + levels + falls — drawings note 9 (S100, S200) explicitly says "refer to architectural drawings for all setout, levels, falls etc." Architectural set NOT supplied. **Quantity take-off cannot be confirmed dimensionally without arch plan.** Provisional take-off uses visually-scaled estimates from S50/S100/S200 grid spacing — flagged in Bid Prep as primary RFI.
- Stormwater drainage drawings — note 5 (S200) refers for "location of pump well + sump pits". Sumps + waterstops + drainage are NOT LFCS but locations affect slab penetrations + trimmer bars for pricing.
- Geotech report S2348_GL_02_Rev0 — referenced but NOT in inbound set. Bearing capacity assumed per drawings note 1 (210 kPa stiff clay). Geotech read-through NOT required for first-pass take-off (founding-layer responsibility lies with HC + geotechnical engineer per drawings note 5).
- Shelter shop drawings (post footings) — referenced from S51 ("REFER TO SHELTER SHOP DRAWINGS FOR POST FOOTINGS") — NOT in this set. Post footings under seating-terrace shelter pavilion may be additional pad footings beyond S100. RFI required.

## Vision-extraction confidence per sheet

| Sheet | Text-pass extracted | Vision-pass needed | Confidence on key data |
|---|---|---|---|
| S000 | Yes | No (notes only, no plan) | High — notes clear |
| S50 | Partial — geometry only | Pending vision pass on dimensioned overlay | Low — no figured dims; relies on grid-scale-bar |
| S51 | Yes — sections + details | Vision pass useful for stepped-SF1 quantity-counting | Medium — visual count of stepped SF1 lifts |
| S100 | Partial — schematic clear, dims partial | Vision pass useful for grid spacing scaling | Medium — figured dims absent on this sheet (grid only) |
| S200 | Yes — slab thicknesses, joint symbols, schedules | Vision pass useful for slab-extent perimeter scaling | Medium — figured dims absent |
| S201 | Yes — RLs, sections | No additional vision needed | High — RLs explicit |
| S300 | Yes (out of scope) | n/a | High |

Vision-pass status: text-pass extraction sufficient for first-pass provisional take-off. **Architectural-plan RFI is the primary blocker, not vision-pass density.** Vision-pass on S100/S200 would refine perimeter lengths but cannot recover figured dimensions that are not on the sheet.
