Price every instructionthe week it lands.
Cellect is a set of agents that sit on a development’s cost plan, programme and record. They price every change the week it is issued, keep the four teams who cause those changes writing to one ledger, and show you where the job will land instead of where it landed a month ago.
Forecast deviation from datum, week 0 to week 36
Façade re-spec opened the excursion in week 11 on INS-041; Groundworks let below allowance closed it in week 17 on LET-003. Of 13 postings, 2 were made with the forecast standing outside the band.
Where every posting landed
Six packages let against a £48,200,000 datum, and the 13 instructions, lettings and released sums posted against them since. Fills compare along a row, each against that trade’s own largest movement.

What would take it outside.
The programme priced at the weekly preliminaries rate the extension of time was agreed at, against the part of the envelope that is not yet certified. Every figure in the grid is the deviation from datum that combination would produce.
The tightest that still holds is +6 weeks at +2%, with £2,000 of headroom.
From NOT-007, the 3-week extension agreed at £96,000.
One point on the rate moves the out-turn by £45,500.
Every posting carries the lane it came from.
Cost raised 8 of the 13; procurement is the only lane that took money out. Each lane foots to its own figure, and the four foot to the movement the matrix reports.
