## 2026-05-06
- 2026-05-06 — LFCS — Letter of Offer submitted to TCE for the FRP Package (P424). Filed at `02a/2635_Letter-of-Offer-LFCS-submission_2026-05-06.docx`. Awaiting TCE response.

## 2026-05-12
- 2026-05-12 — LFCS — ACROW formwork system quote received for the abutment walls (panels-and-soldiers + Slims options). Filed at `02c/2635_ACROW_Formwork_Quote.pdf`.

## 2026-05-14
- 2026-05-14 — cowork — Job folder scaffolded in vault per LFCS folder pattern (01-11 sections + _Archive). Files from `Downloads/2635 TCE Hammond Canal Bridge Munmorah/` synced into vault sub-folders. CLAUDE.md + 00-brief.md drafted from Downloads-bundle filenames (BOQ, ACROW quote, 90DD drawings, Letter of Offer, abutment + walkway references). Bid status: LoO submitted 2026-05-06, awaiting TCE response. Open items: cross-check vs `2602 Dec Projects Munmorah Bridge` (potential overlap flagged by Huss in 2626 brief), read prior `TCE-242-HCB-Bridge` (completed) for lessons-learned, and verify scope against BOQ + 90DD drawings before next TCE conversation. → [[01_Daily/2026-05-14]]
- 2026-05-14 — cowork — **CONFIRMED: 2602 Munmorah Bridge (Dec Projects HC) = 2635 Hammond Canal Bridge (TCE HC)** — same physical job, same BOQ, identical $434,461.81 ex GST submission. Different head contractors only. 2602 reverse-engineered grill analysis (cowork-lfcs, 2026-05-06) applies directly to 2635. All Tier 1 grill open items carry over and are unresolved at TCE. → [[01_Daily/2026-05-14]]
- 2026-05-14 — cowork — TCE contact confirmed: **Mohammed Selim**, Project Manager, `mselim@tcecontracting.com.au` (per LFCS Methodology Proposal v2 DRAFT addressed to him). Updated `00-brief.md` frontmatter. → [[01_Daily/2026-05-14]]
- 2026-05-14 — cowork — **WBS v1 DRAFT** built from BOQ + LoO + 2602 grill, filed at `04 - Programme and Scheduling/2635_WBS_v1_DRAFT.md`. 11 stages (Prelims → Blinding → Abutments → Diaphragms → Wingwalls → Super-T Pre-placement → Super-T Launch → Deck → Approach Slabs → Barriers → Demob), tied to BOQ line refs. Programme basis: 7 weeks / 6 wk plant / 8-man crew / ~2,750 mhrs. → [[01_Daily/2026-05-14]]
- 2026-05-14 — cowork — Decision: **blinding pulled into LFCS scope** (currently excluded in LoO — needs variation paper before mob). 100mm thick, full footprint across abutments + wingwalls + approach slabs, +600mm overpour past abutment line for Slim push-pull bolt-down. Rationale: own the datum so we don't fight bad groundworks levels up the whole build. → [[01_Daily/2026-05-14]]
- 2026-05-14 — cowork — **Outbound enquiry list for Mohammed/TCE** filed at `06 - Correspondence/06a - Emails/2635_TCE-enquiry-list_DRAFT.md`. 24 items in 4 tiers; Tier 1 = 7 critical items must resolve before contract execution (bid status, +1000mm barrier geometry, 9.2.2 $29,823 unaccounted, cranage conflict, saw-cut exclusion, SoR empty, blinding scope-add). Queued behind LFCS Methodology Proposal v2 send (photos pending). → [[01_Daily/2026-05-14]]
- 2026-05-14 — cowork — **Decision: build 2635 in SketchUp Pro (30-day trial) using LFCS component library `.rb` plugin** for boss step-by-step deliverable Monday + carpenter work-pack template. Components: Acrow Slim panels, PP25 push-pulls, LVL 95/150/200×45, F17 formply 2400×1200, scaffold tube ø48.3, Super-T girder (parametric), precast parapet barrier, elastomeric bearings, HD anchor bolts, N12/16/20/25 reo. Cowork to write `.rb` overnight, ready Friday Window. Long-term unlock: stage-PDFs for carps replace daily over-the-shoulder supervision. → [[01_Daily/2026-05-14]]
- 2026-05-14 — claude-code-opsman — **Vision pass on 90% DD pack (38 sheets, 21 MB) complete.** Extract written at `03 - Plans and Specifications/03a - Issued for Construction/2635_DRAWING_DIMENSIONS_EXTRACT.md` with full YAML schema + narrative. Headline finds: (1) project name correction — Bridge at Colongra Power Station, Station Road, Colongra NSW; end client GPM; designer Northrop Newcastle; (2) **4 girders not 6** — re-cost WBS Stage 5+6; (3) **parapet IS thrie-beam not concrete** — confirms Rocky hunch, strip $15-25k from base; (4) **diaphragm question resolved** — both end-block (precast in Super-T) AND 3 intermediate per girder (precast) PLUS cast-in-place cross-girder at each abutment; (5) **barrier post anchorage in girder upstand kerb (precaster scope), not deck reo** — repackage Stage 7.2 (drop 1200kg HD bolt assumption, ~315kg N12 dowel bars actual); (6) **canal-wall saw-cut IS in design** — Tier 1 enquiry stays open; (7) WW4 designed 10kPa surcharge vs others 20kPa; (8) **bridge skew = 0°**; (9) no deck drainage on structural pack — query civil drawings re: WBS Stage 5.4 PVC 64.8m; (10) blinding 75mm not 100mm under headstock. Cowork tomorrow rebuilds `.rb` defaults + updates WBS + 00-brief.md from this extract. → [[01_Daily/2026-05-14]]
- 2026-05-14 — Rocky — **Methodology Proposal v2 SENT to Mohammed Selim 17:40 AEST** (cc Mohamed E, Ahmed Gomaa, Liam, Admin). Mohammed RESPONDED INLINE same day. Major scope clarifications: **(1) NO temp walkway** — Gr-01/Gr-04 have cast-in upstand kerbs with thrie-beam + kick-board + pedestrian rails BOLTED ON BEFORE Super-T installation, provides fall protection from Day 1; LFCS deck FRP between inside faces of outer kerbs only; (2) **NO deck scupper drainage** — sheds off to canal direct, BOQ 7.2.2.3 PVC 64.8m unsupported; (3) **All scaffolding LFCS scope** confirmed; (4) **LFCS blinding scope confirmed** — TCE supplies permanent materials; (5) Super-T fabrication NOT STARTED — design changes still possible; (6) Curing per TfNSW B80, 7-day wet curing on deck. Closed RFI items: walkway, drainage, scaffold split, blinding scope, Super-T fab timing, curing. New open: who bolts thrie-beam to outer kerbs (precaster vs LFCS pre-lift), cast kerb dimensions, blinding concrete supply. Full exchange filed at `06 - Correspondence/06a - Emails/2635_TCE-Mohammed_proposal-and-response_2026-05-14.md`. → [[01_Daily/2026-05-14]]

Drawing Analyser methodology saved as reusable pattern in MEMORY.md.
- 2026-05-17 — **NEW SCOPE surfaced from 90% DD analysis (not in 2602 BoQ)** — adds ~$42k ex GST: maintenance access stair Abut B (1 only, ~$9k), maintenance access slabs both abutments (~$16k, Abut A below water RL so dewatering excluded/Arki), lateral restraint blocks at headstocks (~$5k), S87.01 N20 mass concrete plugs + surrounds at drainage outlets (~$2.5k), end-of-deck N28 cage premium for high-density labour ($3-5k), 352 D6 ferrule connections at deck-abutment interface, approved formwork engineer certification per S60.02 ($3k).
- 2026-05-17 — **Mohammed Selim red-line CONFIRMED on drawings:** Item 1 (cast kerb on Super-T precast) CONFIRMED S60.01-02 = LFCS deck edge stop-end only (-$5-10k); Item 4 (no scupper drainage) CONFIRMED no hardware on S60.01-02 (DELETE BoQ 7.2.2.3 = -$3,216); Item 5 (curing) — DRAWING SAYS "minimum 7-day SEAL curing" not wet curing per Mohammed — RFI tension; Item 7 (all scaffold LFCS) — confirmed; Item 8 (no Super-T ferrules) confirmed in design.
- 2026-05-17 — **Spec LOCKED from S20.01 hi-res pass:** Substructure 40 MPa B1, TfNSW TS 01733.1, 18mm ply + 10mm polystyrene formwork, 20×20 chamfer, **7-day SEAL curing minimum** (RFI tension vs Mohammed 7-day WET curing), 27°C max pour temp, F-class NOT stated (RFI).

Reo D500N to AS/NZS 4671, 45mm cover substructure. **8× LEB 480×380×143 H p/n 070909R bearings confirmed** (matches existing buildup ✓). **Abut B reo HEAVIER than Abut A** — AB1-AB25 vs AA1-AA23 + extra bundle (asymmetric design, BoQ may have assumed mirror — RFI MC22 to TCE).
- 2026-05-17 — **10 RFIs (21-30) drafted in caveman style + ContractorOS RFI template** (file: `LFCS/Projects/2635/06b/2635-RFI-batch-2026-05-17.md`). Email TO Robert Logan (DEC, external QS) drafted in v2 with drawing references per RFI + A/B/C triage ask (send Mohammed / Robert answers / carry as exclusion). **EMAIL SENT to Robert Sunday evening — Liam impressed Monday morning.** Pattern saved as `feedback_lfcs_rfi_email_pattern_validated.md` in memory: caveman + numbered + drawing ref + cost-swing flag + A/B/C triage + Sunday pre-Monday-call timing.

Gap vs CC v1 ($407,870) under Option B = +$28k (+6.8%) — defensible. Bid lock-in pending Robert's A/B/C call (Monday) + Mohammed responses to forwarded RFIs.
- 2026-05-17 — `state.json` machine-readable state created at local LFCS/Projects/2635/0. AI Context/state.json. Vault folder retained for HQ-Vault discipline (append-only `_Log.md`, drawings, methodology proposals, RFI register). Local folder = working drive (faster + per Rocky 2026-05-16 decision: "we are not going to change the folder structure on Hasibul's computer we are only doing this for our folders").
