THE PRE-CON PACK™ STAGE 04 · THE LEDGER

The Ledger

Every line quantified. Every order committed.
The unpriced Bill of Quantities becomes the financial backbone of the project — every line item traceable to a specification clause, every procurement commitment tracked against budget. This is where pre-construction turns into commitment: orders placed, suppliers locked in, and the gap between target and actual begins to close.

Handover note to Stage 05 — Green Light Stage 05 opens Wed 17 June 2026. This is the final QA pass before handing the project to the delivery team. Inputs: all 5 client deliverables (PS, DSW, DI, SEP, UPB), plus the live procurement tracker and risk register. The QA gate checks: every specification clause traces to a BoQ line, every BoQ line traces to an order, every order is programme-compliant, and the financial baseline is clean enough for Margin Cockpit to inherit. Three items still need closure: WP-06 reception order (due Wk 9), WP-11 AV order (due Wk 9), WP-08 accent finishes order (due Wk 9). Delivery plan (PDP) drafted alongside Stage 05 QA and issued as the sixth client deliverable at handover.

THE LEDGER — SNAPSHOT

Orders placed. Budget holding.

A project that enters site with structured procurement — orders placed against like-for-like evaluations, commitment tracked against budget at line-item level, bonds secured, sub-contracts issued — starts construction from a position of financial control. The pre-mobilisation margin uplift of £27,950 is the first result the Margin Cockpit will inherit.
