Kerro measures your drawings, tracks the work done on them and builds your payment application with the evidence behind it. Every variation, RFI and instruction is kept and chased. Need to know something about a job? Ask, and it answers from your own records.
Most firms keep the take-off in one spreadsheet, progress in another and the application in a third, and the three never quite agree. In Kerro they are one line of work.
01
Pipework, ductwork, containment, fittings and equipment are taken off on the drawing itself. A new revision is laid over the old one with every change boxed, and once the take-off is signed off, anything the drawings say differently is listed as a possible variation.
02
Recorded on the drawing: tap the runs that are done, stage by stage, with the photos behind them. The office approves what site records, and a stage that needs a test counts only once a passed test covers it.
03
One register from the instruction to the agreement, including work not instructed yet. Each step writes its own letter: the notice, the confirmation of a verbal instruction, the quote. And what the work took is set against what was agreed.
04
Your contract's own lines, valued from the measured progress to the penny, with variations, dayworks, materials, retention, CIS and VAT, and the Construction Act's dates worked out. It goes out as a PDF and in Excel, the progress drawings behind every figure attached.
What you measure is what you track and what you apply for.
