Measurement Book entries
Each entry belongs to a task and a work package and records where it was measured — floor, zone and grid reference —
and the drawing and revision it was measured against. Dimension lines carry the original formula as written
(12.00 × 0.23 × 3.05), the unit it was written in and the normalised quantity, so a reviewer can check the
arithmetic rather than trust a total.
- Entries can be split across tasks when one measurement covers more than one work package.
- Photos, test reports and approvals are attached as evidence and settled against the entry.
- Revisions supersede entries; nothing is overwritten, and the book keeps its own numbering per project.
- A unit registry keeps m, m², m³, running metre, number and tonne consistent across the project.
From measurement to claim
An RA claim draws on certified, unbilled Measurement Book sources. Claim lines reserve quantities, so the same measurement cannot appear on two claims; the claim shows the reconciliation between what was measured and what is being claimed. Deductions (retention, TDS, advance recovery, material debit) follow the subcontractor's agreement terms, and a payment allocation draft can be saved offline and finished later.
Certification and payment readiness
Certification is a separate, versioned decision on the claim. Payment readiness is checked again on the server when a payment is approved, so a claim that lost its basis cannot be paid by accident. An authorised person can override with a recorded reason; the override is part of the audit trail.
The subcontractor's view
A subcontractor statement lists the agreement, the measurements released against it, claims raised and certified, deductions and payments, with the task payment trace behind each line. The statement is what gets discussed on site, so it is the same record the accounts work from.
