Certainty has a
meridian.

Cellect holds every scheme to one copper line. Cost, programme and site truth are measured against the same locked baseline, and the movement away from it is the thing you are shown first.

02 · The record

This is week 34 at Ardleigh Wharf.

Baseline fixed 11 Feb 2026. Each bar is measured from a copper zero, the ledger’s own repeat of the page’s datum, so a package that has left tolerance is visible before you read a single figure.

† Contingency movement is a drawdown released into the packages above, not a saving, so its bar is clamped to the scale rather than allowed to set it. Figures on this page are an illustrative scheme.

03 · The method

It takes three moves, and they only work in order.

Fix the baseline

One locked datum for cost, programme and scope. Everything after it is measured against that line, not against the last version of the truth.

Catch the drift

Design, procurement and site signals reconciled while there is still room to act on them, rather than at the valuation that closes the month.

III

Prove the out-turn

Owners, approvals and evidence stay bound to the number, so the report you hand a lender is the report your team already works from.

CostFacade +5.8%

Every design move re-priced

Residual and build cost re-cut the moment a drawing changes, not at the next valuation.

Programme6 days late

One critical path

Design, buy-out and build dependencies held in a single sequence, so a facade delay shows up as a completion date.

Site66% certified

What the site actually says

Progress valued on the day it is measured, not on the day the certificate is typed.

Risk3 outside gate

Variance you can still act on

Movement past the contractual gate of ±2.5% is flagged in plain language, before the month closes on it.

Evidence travels with the number

Drawings, quotes and approvals stay attached to the figure they moved.

An honest out-turn

Forward cost and dates restated as facts arrive, not at quarter end.
