## Status

**Stage:** Bid (in prep, dayworks variation per RFI 36) · **Bid due:** This week, exact day TBC · **Type:** TfNSW dayworks (T+M)
**Active Bid:** `recJFeA83SRGOne1s` — `2626-bid-v1-CC-rev5` — **$43,143 ex GST / $47,457 inc GST** (FRP-INSTALL-ONLY scope after Cowork's rev3-5 refinement)
**Bid history:** 6 revs (Cowork v1 superseded · CCC rev2-rev4 superseded · CCC rev5 Active)

## What I Know

- LFCS = pure FRP install only on demolition + reconstruction of an existing brick kerb-inlet pit (750×800×850mm) sitting on top of a **live** DN900 RCP at Forest Rd / Boundary Rd, Peakhurst NSW.
- New pit = TfNSW R0220-style cast-in-situ stormwater pit constructed AROUND the live pipe.
- **Mack Civil supplies:** concrete + reo + lintel (R0220-03) + grate (R0220-04) + step irons + sand bedding + backfill + pipe + ERSED + traffic control + lighting + survey + spoil disposal + machine excavation + demolition.
- **LFCS supplies:** formwork ply + Bituthene + curing compound + grout/hydrophilic seal + small tools + ute&tools. Nothing else.
- Pricing posture = **defensible-for-variations** per Rocky's grill (Rate Card V1.7 night rates $140 trade / $150 supervisor are the basis; variations bill at the same rate).
- Programme = night-only Sun-Thu typical TfNSW (per RFQ Construction Programme — confirm with Mack).
- **Midnight crossing loading applies** — Rate Card V1.7 clause: extra 8 hr day rate per person per shift. Easy to miss; cost CCC rev1-2 $9,080 before Cowork caught it Round 2.
- Compliance: TfNSW R11 + R53 specs (project-specific Oct 2024). Hold Points: 4.4.2 Cert of Conformity, 5.2 CCTV inspection, R53 2.4.3 NATA mix project assessment. Witness Points: 4.3 + 4.7.2. ~1.5 supervisor-days of QA admin ($1,425) + Engineer Cert of Conformity ($500 LS external).
- Designer = TfNSW Standard Drawings (R0220-01, R0220-03, R0220-04, R0220-28).
- Hornsby Bid (`hornsby-bid-v1`, $324K Submitted Mar 2026) was used as STRUCTURE template for the quote layout — NOT rate basis (Mazzitelli QS uses $100/hr, not LFCS $85/hr).

## Job-specific notes / risks / open items

1. **#1 RISK: RFI 36 contractor acceptance NOT YET SIGNED** by Mack Civil (page 5 of RFI). LFCS should NOT commit fixed-price labour/materials until signed. Track via Airtable RFIs row `rec12vNzv7QRNbaog`.
2. **AfC drawings NOT in pack.** Working from R0220 standard + RFI 36 proposal sketch. Quantity assumptions per `00-brief.md` "Quantities at a Glance" — verify against AfC when supplied. Carry assumption clause in submission.
3. **Live DN900 RCP through pit footprint.** Existing pipe carries flow during construction. Non-destructive excavation around required (R11 4.7). Strike risk = high consequence (TfNSW NCR + flow stoppage). Pipe-strike repair excluded unless caused by direct LFCS strike.
4. **R11 + R53 spec compliance burden** — TfNSW Project Quality Plan, Hold Points (4.4.2 Cert of Conformity for joints pre-backfill, 5.2 CCTV inspection, R53 2.4.3 NATA mix project assessment), Witness Points (R11 4.3 + 4.7.2), Identified Records (R53 3.3.2 concrete temperature). ~1.5 days supervisor admin. Engineer Cert of Conformity required ($500 LS, external).
5. **Dayworks docket discipline** — RFI 36 §5: each shift signed by MC Site Sup + TfNSW SO at end of shift. Unsigned = unpaid. Site supervisor hand-delivers + LFCS keeps originals + photo-copies.
6. **5 unknowns from Huss check-in 2026-05-04** still in flight (per `00-brief.md` Huss section): bid contact, exact bid date, pricing basis (Lump Sum vs T+M), RFI acceptance status, AfC drawings. Rocky to chase Mack Civil.
7. **Pricing iteration history** — 5 revs (v1 → rev5) tracked in AB-Test-Tracker.md Rounds 1-3. Active = rev5 ($43,143 FRP-install-only). Cowork's scope-refinement caught what CCC's initial rev1-4 missed (supply-side defaults + midnight crossing loading).
8. **Hornsby reference Bid** (`hornsby-bid-v1`, $324K Submitted Mar 2026) was used as STRUCTURE template for 2626 quote layout — NOT rate basis (Mazzitelli QS uses $100/hr, not LFCS $85/hr).

## Patterns (cross-cutting concept notes — read for context)

This job follows the **TfNSW R0220 Stormwater Pit Pattern**. Applicable concept notes (read these for the lessons baked in from prior pit jobs):

- **`[[lfcs-standards/concepts/TfNSW-R0220-pit-pattern]]`** — FRP-install-only convention default, supply boundary table (Mack supplies concrete + reo + lintel + grate + step irons + sand bedding + backfill + everything else), R11 + R53 spec compliance burden, R0220 standard drawings, midnight crossing loading watch
- **`[[lfcs-standards/concepts/Defensible-for-variations-posture]]`** — pricing strategy applied here; Rate Card V1.7 night rates ($140/$150 supervisor) are the basis. Variations bill at the same rate = clean QS defence. Cowork's scope-refinement rounds (rev3-5) settled on FRP-install-only at $43,143 ex GST.
- **`[[lfcs-standards/pricing-checklist]]`** — universal pre-pricing checklist; Common Misses log includes the midnight-crossing-loading miss CCC hit on rev1-2 (caught by Cowork in Round 2)

## Common Rocky-queries — quick handlers

- **"What's the active bid?"** → Airtable `Bids` filtered by Job=2626, Status!=Superseded → Active is `2626-bid-v1-CC-rev5` ($43,143 ex GST, FRP-install-only).
- **"What's the bid history?"** → `Jobs.Bids History` link → 6 rows (5 CCC revs + cowork-lfcs's superseded v1).
- **"Is RFI 36 signed yet?"** → Airtable `RFIs` rec12vNzv7QRNbaog → `Contractor Acceptance Signed?` checkbox. Status=Responded means TfNSW SO signed but Mack Civil hasn't.
- **"What are the LFCS-scope materials?"** → Per rev5: formwork ply + Bituthene + curing + grout/seal + small tools + ute&tools only. Everything else by Mack.
- **"What's the QA admin?"** → 1.5 supervisor-days @ $95/hr ($1,425) + Engineer Cert of Conformity ($500 external).
- **"What's the midnight crossing loading?"** → $9,080 per Rate Card V1.7 ("Night Shifts extending past midnight will incur an extra 8 hours at day shift rate"). Every shift on this job crosses midnight if night work — 5 trade shifts × 2 men + 3 sup shifts × 1.
