# 2627 — Clarification & Exclusions (skeleton)

## 2627-specific overrides applied this revision

These deviate from Standard. Confirmed at Phase 1 intake gate (assumptions-log-2627.md).

| Standard | 2627 override | Reason |
|---|---|---|
| Labour: direct × 1.10 cont × 1.15 margin = 1.265 | **Labour: direct × 1.15 cont × 1.15 margin = 1.3225** | Rocky 2026-05-08 — drawings rev D pre-IFC, full pre-IFC posture |
| Materials: direct × 1.15 margin × 1.10 cont = 1.265 | **Materials: direct × 1.15 margin × 1.15 cont = 1.3225** | Orchestrator-applied parallel uplift; flagged for Rocky review at sanity-check |
| Concrete grade per element schedule | **32 MPa all elements** (footings + slab on ground + pathway slab + drop edge beams) | STR25020 S100/S200 concrete quality table |

(Worker may add overrides in Phase 3 first-pass take-off; Rocky reviews in Phase 4 sanity-check.)

## Detailed Exclusions, Assumptions & Inclusions (29+)

### Exclusions

29. All bulk earthworks (excavation, backfill, compaction, lean-mix blinding placement) — by earthworks sub
30. Steel screw piles, bored piles, driven piles — by piling sub (drawings S100 + S200 note "PIERING MAY BE REQUIRED. ENGINEER TO CONFIRM DURING CONSTRUCTION" — pier scope is variation if confirmed)
31. Triton mattresses (geofabric) — n/a (no marine works)
32. Shotcrete application — n/a
33. Demolition (including local removal of existing wall below to accommodate concrete riser per S200 note) — by demolition sub
34. Precast supply — n/a (sandstone retaining wall blocks supplied by HC per S51 detail; LFCS does NOT lay)
35. Precast install (lift, place, level, set, brace) — n/a
36. Precast bedding anchors — n/a
37. Connection or fixing TO precast — n/a
38. Stainless steel handrails — by metalwork sub (per drawings — handrails on seating terrace)
39. Hydraulic / plumbing fixtures — by hydraulics sub
40. Mechanical, Electrical, Hydraulic, Fire, P&ID work — by MEPF subs
41. Landscape (planting + softworks + hardworks + furniture + signage + paving units laid as units + brick edge supply + line marking + kerb + gutter beyond LFCS in-situ pavement scope) — by landscape sub
42. Waterproofing trades (FRC sheet, bitumen paint, polyurethane coatings, sealing per drawings S200 note 6 — "ALL EXPOSED SLAB TO BE WATERPROOFED BY APPROVED SYSTEM") — by waterproofing sub
43. Masonry / blockwork / brickwork — 190mm block walls + brick walls per S100 + S200 — by masonry sub
44. **Sandstone block retaining wall** (300×300×1000 long blocks per S51 detail) — supply + place by masonry / specialist sub. LFCS does NOT lay.
45. **Brick walls** (per S100 brick wall above + S200 typical brick wall) — by masonry sub
46. **Block walls** (190mm block above + below per S100 + S200) — by masonry sub
47. Falsework engineering temp works design + verifications — by HC's structural engineer
48. Bypass pumping / temporary stormwater diversion — by HC
49. Out-of-hours, weekend, night-shift work — variation at LFCS Rate Card V1.7 night/weekend loading
50. NCRs, defects, rework arising from drawing variation post-current-rev-D — variation
51. Confined space entry, hazardous area certifications, biohazard PPE — variation
52. Cancellation premium (minimum 8 hrs charged per Rate Card V1.7) — noted
53. **Quantities provisional ±20-30%** subject to receipt of architectural setout drawings (drawings note 9 S100 + S200 "REFER TO ARCHITECTURAL DRAWINGS FOR ALL SETOUT, LEVELS, FALLS ETC." — architectural set NOT supplied in inbound drawing pack rev D). Final price subject to confirmed quantities; quoted total derives from visually-scaled provisional quantities against grid spacing.
54. **Density coring 75-100 mm Ø within 2 days** per pavement spec §14.2.5 — destructive testing taken by NATA lab; **HC pays for core repair** (drill-hole patch + bond agent + epoxy fill). LFCS not responsible for core repair cost or labour.
55. **Late-afternoon pour saw-cut window** — sawn control joints must be cut within 24 hrs of pour per pavement spec §11.3.6 + S200 SJ detail. If 24-hr saw-cut window forces off-hours work (early evening, late night, weekend), variation at LFCS Rate Card V1.7 night/weekend loading (8-hr minimum charge per item 52). LFCS programmes pours to allow standard-hours saw-cut where feasible; HC programme constraints that force late-afternoon pours = variation.
56. **Concrete grade conflict 32 vs 35 MPa for 125mm pathway slab** — drawings rev D S100/S200 concrete quality table specifies 32 MPa; pavement spec P171342-SP-001-0 Table 1 specifies 35 MPa compressive + 4.5 MPa flexural for "pavement Base" element. RFI required for designer clarification. **LFCS placing labour unaffected by grade**; HC concrete-supply line absorbs supply-cost premium (~$300 across 15 m³ pathway). LFCS not responsible for grade-clarification delay if RFI unanswered.
57. **Pavement spec template carry-over** — pavement spec P171342-SP-001-0 §1 Introduction references "St Ives Showgrounds proposed carpark development" (different project). Substantive clauses §4–§15 generic and applied as relevant. RFI flagged for designer confirmation; bid relies on substantive clauses regardless. No pricing adjustment.
58. **Flexural beam testing per pavement spec §14** — LFCS makes + delivers beams; NATA flexural lab cost via HC (per item 28). Designer to confirm flexural retention for pedestrian-load pathway (more typical for heavy-vehicle pavement). Possible scope reduction if flexural waived.

### Assumptions

A1. **Concrete grade 32 MPa** all elements per STR25020 S100 + S200 concrete quality tables. (Supersedes any earlier 25 MPa indication.)
A2. **Working hours** 7:00 am – 3:30 pm Mon–Fri unless HC instructs otherwise.
A3. **Programme** TBD (to be confirmed by HC at RFQ stage). Rates assume a continuous run; broken programme = variation at day labour.
A4. **Drawings rev D** — current rev. Worker to flag any post-rev-D updates at Phase 3.
A5. **Site classification AS2870 Class H1**, bearing 210 kPa stiff clay (per drawings note 1 + geotech S2348_GL_02_Rev0). LFCS not responsible for verifying bearing capacity (item 14 above).
A6. **Saw-cut joint timing** — within 24 hours of pour per S200 SJ detail.
A7. **Curing** — polythene + hessian per pavement spec §10. **7-day cure** per pavement spec §10.1.1 minimum (corrected from 14 days at revision 1; pavement spec wins by precedence).
A8. **Productivity** — pavement scope assumed at 160 m²/day (industry standard for in-situ concrete pavement); footings + slabs assumed at standard LFCS rate-card output, with productivity adjustments per A10–A12 below.
A9. **Adverse weather** — excluded; variation at day-labour rates per item 7.
A10. **Existing-slab interface productivity reduction 15-20%** built into per-line rates for tooth slab + tooth stair into existing slab/brick wall + drill+epoxy N12-400 dowels + local wall-removal coordination (drawings S201 sections 1+2 + S200 typ toothing detail). LFCS not responsible for unforeseen interface conditions beyond what is shown on drawings rev D — any additional dowel / waterproofing / patching arising from existing-structure conditions revealed during construction is variation.
A11. **DEB1 deep-edge-beam productivity reduction 30%** built into formwork + reo + place rate (1200 deep × 300 thick × 13 lin m; multi-layer cage; tremie place; heavy props). LFCS not responsible for delays caused by DEB1 prop-removal cylinder-test timing per S000 concrete note 9 (28-day OR 14-day-with-cylinder-test gates prop removal; if HC's NATA cylinder testing programme delays prop removal, standing time is variation).
A12. **Stepped SF1 seating terrace productivity reduction 10-15%** built into rate (3 stepped lifts per S51).

### Inclusions (LFCS supplies)

I1. Plastic spacers (no metal chairs — galvanic corrosion)
I2. Polythene + hessian curing for 7-day cure (per A7 corrected)
I3. Formwork ply + timbers + props (assumed LFCS-supplied unless drawings note TCE-supplied — confirm at Phase 0 grill Q-A3)
I4. Diamond saw + dust suppression for joint forming
I5. Megapoxy bonding agent (rare; usually TCE — flag if drawings spec'd)
I6. Concrete pumping vibration ONLY where LFCS placing crew runs the vibrator (pump itself by HC per item 19 above)
