Measurement Book

The record of what was actually built, measured on site and signed for. An entry says how many units of a BOQ line were done, at what length, breadth and depth, and where on site - and somebody separate from the person who measured it certifies it. Only certified work moves a BOQ line, and only certified work can be billed.

Switch: Settings > Site Work > Measurement Book. Permissions: Record Measurements to write an entry, Certify Measurements to sign one.

Why it matters

With the book off, a BOQ line's completed quantity is moved by the site diary's own "done today" figure. Nobody signs for that figure, so a running-account bill can charge a client for work nobody has agreed was done - and when the client disputes it, there is nothing to argue from.

With the book on, quantity reaches a line only through a measured entry that has been certified. The completed figure is recomputed from the certified entries rather than added to, which is what makes striking one work: un-certify a measurement and the line moves back by exactly what that entry contributed, to the paisa.

Two people, on purpose

Recording and certifying are separate permissions because on any job of size they are separate people: the site engineer holds the tape, and somebody else signs for what it read. That separation is the entire reason a measurement book exists. On a small builder both land on one person - that is a choice the business makes, not one the app forces, so grant both by hand if that is how you work.

Where it appears

Construction shell: Measurement Book in Site Operations (pick a project), with a badge counting measurements recorded and not yet signed. A Site Engineer seat lands on this screen when they sign in. Also the Measurement Register report, across every job at once.

Flow

flowchart TD
    A[Site engineer measures a BOQ line
units × length × breadth × depth · location or chainage] --> E[(Entry recorded · awaiting signature)]
    E --> Q{Certified?}
    Q -->|not yet| E
    Q -->|signed| R[Completed quantity RECOMPUTED
from every certified entry on the line]
    R --> D[RA bill draft = certified − already billed
at the BOQ rate]
    D --> B[(RA bill raised)]
    Q -->|struck off| U[Un-certify: the line moves back
by exactly what that entry contributed]
    U --> R
    R --> V[BOQ variance: physical progress
against money burnt]

Recompute, never add: an increment cannot be undone, and a measurement struck off has to leave no trace in the figure.

Screens

Measurement Book - the job's entries, what each measured, who signed it and whether it has been billed. The quantity is worked out from the dimensions as you type, so nobody multiplies by hand.
Certify / Un-certify - one action on the row, behind Certify Measurements. Both recompute the line immediately.
Measurement Register - every entry across every job, so somebody can find the entries that have sat unsigned for a month on a site nobody is watching.

An entry that has been billed cannot quietly change. Cancel the bill first; that releases the work so it can be measured and billed again.

Setting it up

flowchart LR
    A[Settings > Site Work
Measurement Book on] --> B[Enter the BOQ lines first
a measurement is measured AGAINST one]
    B --> C[Add a Site Engineer seat
Record Measurements]
    C --> D[Give Certify Measurements
to somebody else]
    D --> E[Record the first measurement]
    E --> F[Certify it · the BOQ line moves]
    F --> G[Raise the RA bill from what is certified]

Switch it on, put the BOQ and the two seats behind it in place, then measure — in that order, or the first entry will have no line to measure against.

Switching it off hands the completed quantity back to the site diary, so bills stop being backed by a signature. Existing entries stay in the book.
