# 2630 — Clarification & Exclusions

## 2630-specific overrides applied this revision (2026-05-08 rev 4)

These deviate from Standard. Do not generalise to other jobs without confirmation.

| Standard | 2630 override | Reason |
|---|---|---|
| Adverse weather = variation at day-labour rates (per 2629 #37) | **Adverse weather INCLUDED in prelims** at 1 day per fortnight (~5% working days) | Rocky 2026-05-08 |
| Saltwater +5% consumables uplift (Concept Pattern Q-G7 yes-tidal) | **Stripped — site is NOT tidal** (above tide line; standard coastal-air exposure) | Rocky 2026-05-08 |
| Labour rate base $85/hr LFCS Rate Card V1.7 | **$95/hr blended all-in** for all LFCS labour. Build-up: 8hr × $85 + 2hr × $105 + 1hr × $120, divided by 10 hrs nominal | Rocky 2026-05-08 |
| Margin = 16.5% per-line / Materials markup = 10% (Concept Pattern lump-sum-FRP-arm) | **Labour: direct × 1.10 contingency × 1.15 margin = 1.265.** **Materials (LFCS-purchased): direct × 1.15 margin × 1.10 contingency = 1.265.** Same final multiplier; order differs per methodology rule. | Rocky 2026-05-08 |

3. Latent conditions
4. Asbestos / contaminated material handling
5. D&C (design-and-construct) responsibility

37. Setting out of precast anchor positions (registered surveyor)
38. Connection or fixing TO precast units (bolting, grouting bolt recesses, levelling shims, post-tensioning)
39. 50 MPa grout shim under precast units — RFI to Hus; default OUT

42. Stage 1 stair rectification works (6367 SK500/SK501, dated 29/01/26) — separate price, OUT of this take-off
43. Triton mattress hung from existing boat ramp (Variation 6367) — separate price, OUT
44. All Mechanical, Electrical, Hydraulic, Fire, P&ID work (E02, E20, H01-H03)
45. Landscape (planting + softworks + hardworks + furniture + signage incl. Emma McKeon promenade signage + paving units laid as units + brick edge supply + line marking + kerb + gutter)
46. Waterproofing trades (FRC sheet, bitumen paint waterproofing, polyurethane coatings, sealing)
47. Sydney Water building plan approval coordination via ACOR Consultants (Olivia Golombick)
48. Don't-drive-piles-near-sewer compliance + WCC structural engineer approval (per S141 important note)
49. Bypass pumping / temporary stormwater diversion / construction-stage dewatering for tidal water at base-slab level (note: site is not tidal but stormwater drainage may still need coverage)
50. Out-of-hours, weekend, night-shift work (variation at LFCS Rate Card V1.7 night/weekend loading — site is day-shift Mon-Fri default)
51. NCRs, defects, rework arising from drawing variation post-current-IFC (issued 7/7/25 = current basis)
52. Confined space entry, hazardous area certifications, biohazard PPE (none anticipated; if discovered = variation per AS 2865)
53. Cancellation premium (minimum 8 hrs charged per Rate Card V1.7)

### Assumptions

54. Drawings basis: IFC issued 22/12/23–8/2/24 (Issue 1) + revised 7/7/25 (Issue 3). Quantity drift ≥5% between current IFC and any subsequent revisions claimed at submission rate basis.
55. Specifications per drawing notes S002-S004 (concrete grades, reinforcement, formwork, curing per AS3600 / AS3610.1 / AS4671 / AS1379 / AS3972 / AS3799 / AS5131 / AS4100). AS3610.1 Class B finish typical.
56. **Site is NOT tidal** (above tide line; standard coastal-air exposure only, no immersion). Marine cement Type LH/SR BCSC + stainless 316 reo + sulphate-resistant footings = design durability margin against airborne salt aerosol, NOT tidal-immersion driven. No saltwater +5% consumables uplift applied.
57. **Labour rate: $95/hr blended all-in** (override of LFCS Rate Card V1.7 base $85). Build-up: 8hr × $85 + 2hr × $105 + 1hr × $120 / 10 hrs nominal day. Applied to all LFCS labour: formwork, steel fixers, concrete finishers, supervision, leading hands.
58. **Adverse weather: 1 day per fortnight (~5% of working days) built into prelims** at $15,200 allowance (5 days × 4-man × 8hr × $95). Beyond 5% threshold = variation at day-labour rates. (Override of 2629 default which excluded weather as variation.)
59. **Margin + contingency build-up:** Labour direct × 1.10 contingency × 1.15 margin = 1.265 loaded. Materials (LFCS-purchased) direct × 1.15 margin × 1.10 contingency = 1.265 loaded. Same final multiplier; methodology rule requires the orderings remain distinct per category.
60. No BoQ supplied by TCE — LFCS take-off from drawings (vision pass at A1 1:100/1:200; ±20% sensitivity). If BoQ subsequently supplied with materially different quantities, variation applies at submission rate basis.
61. Curing: LFCS supplies polythene + hessian for 14-day cure per S003 C16-C17. Chemical curing compounds (AS3799) NOT used (per Standard Exclusions #9 wording).
62. Insitu 350mm slab (Item 2) cast over Stage-2 base slab (Item 1) — surface preparation: scabble top of base slab + Megapoxy bonding agent + Hilti N16-900 L-bar drilling+epoxy 150mm into base slab per S190/S191 (Hilti chemicals TCE-supplied per Prelims #23).
63. Reinforcement quantity (Grade 316 stainless across SW1/SW2/SW3 + H1/H2/H3 + base-slab matt + edge-beam EB1) is take-off-derived from S171/S172/S190/S191/S192 (vision-pass). ±15% sensitivity carries between current IFC and final BBS.
64. Stainless reo cover: 50mm typical per S173 + S191 notes. Plastic chairs only (no metal chairs that cause galvanic corrosion).
65. Bleacher scope (Item 1 in LFCS): in-situ pour of substrate slab beneath the precast bleacher units. The shotcrete-spec base slab per drawings is poured by traditional formwork+place+finish methodology per Hus 2026-05-08. Precast units, anchors, and connections to precast = OUT (per Detailed Exclusions #34-39).
66. Falsework for ramp underside (Item 3 DDA ramp): rate-only allowance, design-by-others. Engineering temp-works design supplied by HC engineer (Standard #10).
67. Pricing posture: defensible-for-variations. Variation rate basis = same as submission rate basis ($95/hr blended × 1.265 loaded).
68. Programme: 10 weeks LFCS crew on site (Rocky-locked). Tight but achievable with adverse weather buffer.

### Inclusions

69. Supply, install, strip formwork to all LFCS-scope elements (slab edges + wall faces + hob faces + edge beam EB1 + planter wall edges + ramp wall faces + paving slab edges + strip footing edges)
70. Place concrete (TCE-supplied) to all LFCS-scope elements — Items 1-4
71. Install reinforcement and mesh (TCE-supplied) — Grade 316 stainless cage tying + plastic chairs + N16-900 L-bar drilling+epoxy into base slab via TCE-supplied Hilti HIT-RE 500 V4
72. Cure concrete using LFCS-supplied polythene + hessian for 14-day cure per S003 C16-C17
73. AS3610.1 Class B finish typical; decorative finish to Item 4 promenade slab per architect spec
74. 20mm chamfers + pencil-round edges to all exposed concrete edges
75. Joint formation saw cuts SJ1/SJ2/WSJ (60mm × 6mm groove sawn within 24h) — LFCS diamond saw + dust suppression + RPE
76. Construction joint forming + scabbling (top of base slab) + Megapoxy bonding agent application
77. Pre-pour deck blow-out + reo pickup + magnet sweep
78. Hop-up boxes / walk boards over reo during pour
79. Concrete cylinder cast + delivery to NATA lab (TCE pays lab)
80. Edge dressing post-strip + tie-wire stub cut-off + grind flush
81. Cast-in items install during pour (LFCS labour only — items themselves TCE-supplied per Prelims #22)
82. Reo material handling on site (incl. stainless cage delivery + storage with plastic chair support)
83. Slump test stand-by + concrete washout area + bucket setup
84. Curing method submission to WCC for approval per S003 C16
85. Sub-PQP and basic ITP per pour (lump-sum prelim)
86. Daywork docket sign-off chain (LFCS Sup + TCE Sup signatures)
87. Site supervision (LFCS PM/Sup) for duration of works
88. **2630-specific: adverse weather standby allowance — 1 day per fortnight (~5% of working days) built into prelims** (override of 2629 default convention)

2. Site exposure category not confirmed before rate-build
3. Labour rate not confirmed before rate-build
4. Margin and contingency build-up rules not in methodology base

## Status

- Lives in `_Internal/exclusions/exclusions-2630.md`
- NEVER sanitised
- NEVER rendered to external artefacts
- Used as comparison surface during reveal phase against Hus's prior 2630 submission exclusions
- Total numbered items: 88 (target was 30-50; expanded to match 2629 inclusion granularity. If Rocky wants tighter, can compress assumptions/inclusions sections.)
