The whole
development,
drawn to scale.
Cellect runs a development’s cost plan, programme and record off one drawing. This is Harlow Yards — 6 levels, 48 flats, 4,838.4 m² gross — and every figure on this page is read back off the section you are looking at.
Cut through the north row of flats, looking north. The two dashed windows on it are enlarged below, at the scale each one needs.Cut through the north row of flats, looking north, and re-cut here to the west half at grid D. The full 38.40 will not hold its 0.25 floor plates at this width, so it is not drawn at it.

The bay2.8× the section above
Change it here, and the ledger already knows.
Every instruction, change order and approval is pinned to the element it moved. The cost plan and the drawing cannot describe different buildings, because they are not two documents.
Envelope
Head at 2.40, cill at 0.90, 24 openings. The window schedule is read off the drawing, so it cannot drift from it.
Fit-out
One flat type, 48 times. Move a balustrade once and 48 line items move with it, priced the same day.
Structure
0.25 of slab, 6 times over 806.40 m². The quantity comes off the section, not out of a typist.
The ground8 elements, 72.8% committed
Under the ground line,
the money.
Eight elements, $21,850,000. Each is drawn as thick as its budget and hatched as far as it is committed, so the hatched ground is the $15,913,450 already spent and the clear ground is the $5,936,550 left.

Substructure is the one line past its budget: $67,750, 3.7% of the element and 0.31% of the whole. At the thickness of this ground it is a mark thinner than the rule under it, so it is cut out and enlarged below.
The cutSubstructure, mark B — 6.3× the section above
Everything drawn here is drawn at the top of this page too, at 0.30 across a 19.40 building — which is why it had to be cut out to be seen.
0.30 of concrete, $67,750.
Nobody re-typed any of that. The survey moved one dimension, and the quantity, the rate, the element line and the revision note followed it in the same afternoon.

The record
latest issue firstNothing moves without leaving a mark. Handover that is not a cliff: the asset arrives with its whole story attached — what changed, when, who issued it, and which element moved. Marks B and C are on the drawings above.
- C
Fit-out packages released for tender. Commitment held at the drawn quantities until returns are in.
Fit-out & finishes — mark C, at the terrace
- B
Ground survey returned. Raft deepened from 0.70 to 1.00 and re-priced; the difference is carried against contingency.
Substructure — mark B, at the raft
- A
Cost plan issued from the feasibility model at the end of concept design.

A scheme, a cost plan, and whatever the last consultant left behind. You get back the section, the ledger cut to the same scale, and a record that starts at A.
