## Q7 — Sanity checks (auto-flags)

- [x] Total bid > $100K — yes ($542K Cowork / $857K V1) — large job, expected
- [x] Total bid < $20K for night-works pit — N/A (day shift, large job)
- [x] No midnight crossing loading line — correct (day shift only)
- [x] Defensive exclusions Block B included — yes, 23 items in Tender Summary Sheet 4
- [ ] Reo qty back-calculated from drawings — N/A (Vaughan supplies reo, not in LFCS scope; productivity assumes typical density)
- [ ] More than 2 LFCS-supplied major materials — only formwork + curing + small consumables (NOT a TfNSW dayworks pit, so the 2-material rule doesn't apply directly; substation FRP-install-only is the same FRP-install-only pattern)

## Open items for Rocky

1. Confirm ALL [TO CONFIRM] items above before submission.
2. **Posture decision:** V1 ($857K) vs v-CW-rev1 ($542K) vs hybrid? — see 00-Bid-Prep.md §4.
3. Confirm CW1+CW2 6-wk plant allowance — is Acrow AW8 the right system, or hire Symons/Doka instead?
4. Confirm Liam's existing 42 V1 exclusions are correct → carried into Block A of v-CW-rev1.
5. Confirm any additional defensive exclusions to add to Block B.
